Full textAbstract:
This work presents a survey literature review on biomechanics, specifically aimed at the study of existent biomechanical tools through video analysis, in order to identify opportunities for researchers in the field, and discuss future proposals and perspectives. Scientific literature (journal papers and conference proceedings) in the field of video-based biomechanics published after 2010 were selected and discussed. The most common application of the study of biomechanics using this technique is sports, where the most reported applications are american football, soccer, basketball, baseball, jumping, among others. These techniques have also been studied in a less proportion, in ergonomy, and injury prevention. From the revised literature, it is clear that biomechanics studies mainly focus on the analysis of angles, speed or acceleration, however, not many studies explore the dynamical forces in the joints. The development of video-based biomechanic tools for force analysis could provide methods for assessment and prediction of biomechanical force associated risks such as injuries and fractures. Therefore, it is convenient to start exploring this field. A few case studies are reported, where force estimation is performed via manual tracking in different scenarios. This demonstration is carried out using conventional manual tracking, however, the inclusion of similar methods in an automated manner could help in the development of intelligent healthcare, force prediction tools for athletes and/or elderly population. Future trends and challenges in this field are also discussed, where data availability and artificial intelligence models will be key to proposing new and more reliable methods for biomechanical analysis.

Full textAbstract:
It is common for sport science practitioners, including sport biomechanists, to interact with high-performance coaches in the daily training environment. These relationships are beneficial for both scientist and coach, as well as the athletes. However, as indicated by difficulties in transferring new research into coaching practice, these relationships are not functioning as well as they could. The aim of this paper is to examine the various factors that influence the coach–biomechanist relationship in the elite sprinting context and gain an understanding of what impedes and enhances this, which will ultimately maximise an athlete's performance. Sprint coaches ( n = 56) and applied sport biomechanists ( n = 12) were surveyed to determine the participants' experiences working with each other and use of biomechanics in the training environment. Semi-structured interviews with coaches ( n = 8) and biomechanists ( n = 8) were conducted to further explore these ideas. From the biomechanists perspective, the relationship appeared to be less effective than from the coaches' perspective and both groups identified areas for improvement. The coaches had an inconsistent understanding of biomechanics theory and the support a biomechanist could provide in the training environment, while it was acknowledged that biomechanists needed to improve their communication skills. Coach and practitioner education were identified as where these improvements could be facilitated. There are many aspects of the coach–biomechanist relationship that could contribute to establishing optimal practice in the high-performance environment and enhance the transfer of knowledge from scientist to coach. This paper proposes a number of directions that could be taken.

Full textAbstract:
In the current information age, knowledge sharing, as one of the core features, provides a new perspective for innovation and entrepreneurship education (IEE) innovation. This study aims to explore the process of cultivating university students’ entrepreneurial ability, optimize the knowledge sharing environment by establishing a specialized biomechanics knowledge sharing platform, strengthen the proportion of practical teaching in biomechanics-related majors, integrate the latest research results and innovation cases in biomechanics into the innovation and entrepreneurship education, stimulate the students’ innovation interest and entrepreneurial awareness, and further promote the college students in biomechanics field to further development of IEE for college students in the field of biomechanics.. By using the research methods of literature review, questionnaire survey, multiple linear regression and structural equation model, this article analyzes the influence of knowledge sharing environment on students’ entrepreneurial will, biomechanics application ability and overall educational effect after incorporating biomechanics concept. It is found that the various complex problems faced in biomechanics research provide opportunities for college students to cultivate innovative thinking and problem-solving abilities; for example, by introducing the application of biomechanics in medical devices, sports science, biomedical engineering and other fields, students are guided to think about how to develop new products or services using biomechanical principles, thus cultivating their innovative thinking and entrepreneurial spirit. the frequency of dissemination and application of biomechanical knowledge in the knowledge sharing mechanism is positively related to students’ entrepreneurial intention, which plays a significant role in improving the biomechanical knowledge and utilization of the students in the process of entrepreneurship. Carrying out biomechanics-related entrepreneurship programs can cultivate the teamwork ability of college students. In the entrepreneurial process, students from different professional backgrounds, such as biomechanics majors, engineering majors, marketing majors, etc., need to work together to transform biomechanical research results into actual products and market them. This kind of inter-disciplinary teamwork can exercise the communication and coordination ability, resource integration ability and team management ability of college students. The results of this study not only confirm the positive effect of biomechanics-based knowledge sharing mechanism based on biomechanics on IEE, but also provide theoretical support and practical guidance for tertiary education institutions on how to optimize the knowledge sharing environment and improve the quality of entrepreneurship education.

Full textAbstract:
Speciation is a multifaceted process that involves numerous aspects of the biological sciences and occurs for multiple reasons. Ecology plays a major role, including both abiotic and biotic factors. Whether populations experience similar or divergent ecological environments, they often adapt to local conditions through divergence in biomechanical traits. We investigate the role of biomechanics in speciation using fish predator–prey interactions, a primary driver of fitness for both predators and prey. We highlight specific groups of fishes, or specific species, that have been particularly valuable for understanding these dynamic interactions and offer the best opportunities for future studies that link genetic architecture to biomechanics and reproductive isolation (RI). In addition to emphasizing the key biomechanical techniques that will be instrumental, we also propose that the movement towards linking biomechanics and speciation will include (i) establishing the genetic basis of biomechanical traits, (ii) testing whether similar and divergent selection lead to biomechanical divergence, and (iii) testing whether/how biomechanical traits affect RI. Future investigations that examine speciation through the lens of biomechanics will propel our understanding of this key process.

Full textAbstract:
Aging process becomes a miserable phase of lifespan of various individuals. Gerontology and Geriatrics exclusively deal with researching complex human ailments pertinent to old age in order to overcome the challenges posed by several irreversible physiological changes occurring with aging. Inevitably, homeostasis declines and massive allostasis gets organized during aging to destroy the functional independence and survival potential. Controlling the rate of aging process is the only possible self-regulating strategy available to each individual to enjoy Morbidity-Attenuated Life Years (MALYs) but maintaining an optimal fitness competence to travel along the healthy aging trajectory is not effortlessly feasible regardless of the socioeconomic conditions. Fitness evaluations on different age groups enhances the understanding that the aging process might be a premature event among several individuals at an early age itself due to multifactorial reasons, and the biomechanical constraints displayed by such individuals expose the probable wide spectrum of postural and movement dysfunctions or disabilities of unhealthy older adults. Many such health-ruining erroneous postures and movements remain asymptomatic perilously, which when addressed during appropriate stage in life, could repair the impaired physical efficiency to sustain the abilities to counteract the effects of gravitational force on the body. The importance of early detection and rectification of such peculiar biomechanical dysfunctions should become an integral part of public health prophylaxis. The repertoire of biomechanical dysfunctions of premature unhealthy aging needs to be strongly merged with gerontology to strengthen the pursuits to retard unsuccessful aging and accomplish successful aging.

This paper provides an overview of the biomechanical considerations related to ankle injury prediction, prevention, and rehabilitation. Firstly, we discuss the biomechanical factors that contribute to ankle fractures, including loading patterns and bone density. We then explore various biomechanical assessment techniques, such as motion analysis, force measurements, and imaging modalities, which can be used to predict injury risk, guide treatment decisions, and monitor rehabilitation progress. Additionally, we examine biomechanical interventions, including bracing, taping, muscle strengthening, and proprioceptive training, which have proven effective in improving ankle stability and preventing injuries. Furthermore, we highlight the emerging technologies of wearable sensors and computational modeling, which offer new avenues for assessing ankle biomechanics and personalizing interventions. Ultimately, this paper emphasizes the integration of biomechanics with personalized medicine as a promising approach for optimizing ankle injury prevention and rehabilitation outcomes. However, further research is needed to address unanswered questions and explore future directions in ankle biomechanics.

Full textAbstract:
The application of biomechanical methods and techniques in rehabilitation treatment has been explored to deepen understanding of the health recovery of injured athletes, thereby improving their efficacy and quality. There are various methods for using biomechanics, which can help people understand the patient’s movement characteristics and mechanical changes, evaluate the patient’s recovery progress, and optimize the plan. Therefore, this article mainly conducted research and analysis on the application of biomechanics in sports rehabilitation, and explained the specific role of biomechanics in it by comparing before and after sports rehabilitation in different situations. The results showed that after treatment with biomechanical methods, the patient’s muscle strength increased by 9.4%–20.93% compared to the original, and the power value increased by 0.8–4.56 watts. The effect was good for achieving 71.28% muscle activity, and there was also a significant improvement in its sports mechanics indicators. After receiving biomechanical treatment, the quality of motor skills in patients was over 60%, which showed significant improvement compared to before treatment. Therefore, when conducting sports rehabilitation, biomechanical treatment plans should be used to achieve better therapeutic effects.

One of the intended learning outcomes of Physical Education (PE) is for students to develop physical skills. Biomechanics can be used as a discipline to measure the level of physical skill. This study aimed to develop an assessment form to measure the level of physical skill. The movement principle of biomechanics was incorporated into an observation checklist form. The form is meant to help Physical Education Teachers (PET) qualitatively analyze students' physical skills using biomechanics. This study aligns with research and development model which conducted in three phases: need-analysis, development, and model efficiency test. The form was built with two main components: physical skill and biomechanical principles. Physical skill is related to standard movement patterns for a given sporting skill. The biomechanical principle lays the foundation for all movements. This research uses a qualitative approach. A total of 120 PET from 120 secondary schools were involved as subjects in this study. Interviews, observation, and questionnaire were used to collect the data. This research yielded the following result, first, there are problems with integrating biomechanics into an assessment of physical skill. Second, a biomechanics form is developed in the checklist-style observation form to help PET evaluate their students’ learning outcomes. Third, biomechanics form was practical to be used as a learning assessment tool because it met the criteria of validity, practicality, and effectiveness.

Laser vision correction became a popular method of refractive error treatment. The laser vision correction techniques influence the corneal biomechanical properties including corneal hysteresis and corneal resistance factor. The ocular response analyzer and Corvis ST devices are used in clinical practice to measure the corneal biomechanics. Reasonable laser treatment planning, taking into account the impact on corneal biomechanics, may potentially improve the safety of the refractive procedures. Thicker caps in refractive lenticule extraction and thinner flaps in flap-related procedures promote better corneal biomechanics preservation. The myopic refractive treatment appears to have a greater effect on corneal biomechanics weakening than hyperopic correction.

In order to improve resource efficiency and enhance sustainability in biological systems, this study investigates the optimization of biomechanical processes by combining genetic algorithms (GA) with human performance and recovery management. The study aims to minimize injury risks and maximize recovery efficiency by utilizing GA to model biomechanical processes. To ensure a dynamic balance in physical performance, the study presents an ideal optimization framework in which human biomechanics is optimized for enhanced sports performance and injury prevention. The model considers factors such as muscle strain, joint impact, and fatigue recovery to create a holistic biomechanical optimization system. By integrating principles from biological nutrient cycles—such as the efficient use of resources and minimizing waste—the approach highlights the parallels between sustainable agricultural systems and sustainable biomechanics. This framework ensures that optimization strategies not only improve performance outcomes but also maintain long-term musculoskeletal health. The research demonstrates how combining biological insights with advanced computational methods can address both physical health and performance challenges in biomechanics. Through multi-objective optimization, the work offers a novel perspective on integrating biological processes with biomechanics to support sustainable human activity and recovery, contributing to advancements in sports science, rehabilitation, and human physical performance.

The role of corneal biomechanical properties in patients referred to laser vision correction (LVC) is currently being raised. Understanding of corneal biomechanics may support the proper selection of refractive surgery candidates, improve the refractive outcomes and safety of refractive procedures. The Ocular Response Analyzer (ORA) and Corvis ST are commonly used devices to assess corneal biomechanical parameters in LVC. The vertical corneal incisions have a greater impact on corneal biomechanics weakening than horizontal incisions. Maintaining the high biomechanical strength of the cornea following LVC can decrease the potential risk of postoperative ectasia.

Full textAbstract:
The study aimed to investigate the extended effects and interrelations of corneal biomechanics, corneal optical density (COD), corneal thickness (CT), and intraocular pressure (IOP) following cataract surgery. Sixteen eyes were analyzed prospectively. The Corneal Visualization Scheimpflug Technology (Corvis ST) device assessed corneal biomechanics, while the Pentacam AxL® (Pentacam) measured COD and CT. Postoperative data were collected around six months after surgery, with a subgroup analysis of data at nine months. The Pearson correlation was used to examine the relationship between surgical-induced changes in corneal biomechanics and COD. At six months, significant postoperative differences were observed in various biomechanical indices, including uncorrected IOP (IOPuct) and biomechanics-corrected IOP (bIOP). However, many indices lost statistical significance by the nine-month mark, suggesting the reversibility of postoperative corneal changes. Postoperative COD increased at the anterior layer of the 2−6 mm annulus and incision site. The changes in COD correlated with certain biomechanical indices, including maximal (Max) deformative amplitude (DA) and stiffness parameter (SP). In conclusion, despite significant immediate postoperative changes, corneal biomechanics, COD, and IOP experienced a gradual recovery process following cataract surgery. Clinicians should maintain vigilance for any unusual changes during the short-term observation period to detect abnormalities early.

Richard C. Nelson started the Biomechanics Laboratory, one of the first of its kind in the world, on the campus of the Pennsylvania State University in 1967. His vision focused on connecting the physiological and mechanical elements of human performance analysis, specifically sport performance. The lab’s engaging, interdisciplinary environment supported self-designed programs of study, benefiting each individual student. Furthermore, the Biomechanics Lab became the nexus for the development of biomechanics as a field of study internationally. Richard Nelson’s diplomatic skills spread the word initially through the formation of the International Society of Biomechanics. This international effort resulted in the development of national societies of biomechanics around the world, for example, the American Society of Biomechanics. Second, these efforts stimulated the concept of sport performance analysis on the international stage. Richard Nelson’s passion was to analyze individual performances at the Olympic Games. This goal was finally realized, with the development of the Subcommission within the International Olympic Committee Medical Commission and biomechanical analysis projects completed at the 1984 Olympic Games in Los Angeles. Richard Nelson’s vision, mentoring style, and dedication planted and nurtured the seed of biomechanics as a discipline of study around the world.

We propose the time-dependent generalization of an "ordinary" autonomous human biomechanics, in which total mechanical + biochemical energy is not conserved. We introduce a general framework for time-dependent biomechanics in terms of jet manifolds derived from the extended musculo-skeletal configuration manifold. The corresponding Riemannian geometrical evolution follows the Ricci flow diffusion. In particular, we show that the exponential-like decay of total biomechanical energy (due to exhaustion of biochemical resources) is closely related to the Ricci flow on the biomechanical configuration manifold.

Full textAbstract:
Background. Floor gymnastics is a sport that involves explosive, acrobatic, and highly technical movements, requiring advanced biomechanical skills from its athletes. However, these movements often carry a significant injury risk, especially to joints and soft tissues. Common injuries in floor gymnastics include those affecting the ankles, knees, and back, generally caused by excessive force or improper technique in specific movements. Given the high incidence of injuries among gymnasts, understanding the biomechanical factors contributing to injury risk is essential for coaches and athletes seeking to enhance technique and safety. Study objectives. This study aims to identify and analyze the biomechanical factors of critical movements in floor gymnastics and their impact on injury risk. By compiling a systematic review of existing research, it seeks to provide in-depth insights into the link between movement biomechanics and injury prevention in floor gymnasts. Materials and methods. This study used a systematic review focusing on biomechanics and injury risk in floor gymnastics. Data were collected from academic databases such as PubMed, Scopus, and Web of Science using relevant keywords, including “biomechanics,” “floor gymnastics,” “injury risk,” and “key movements.” The inclusion criteria encompassed studies that analyzed biomechanics and injuries in fundamental floor gymnastics movements, such as the flip, handspring, and split leap. Articles that met the requirements were then evaluated to assess key biomechanical findings and the types of injuries associated with each movement. Results. This review identified several fundamental movements with high biomechanical demands that affect injury risk, including the flip, handspring, and split leap. The analysis showed that extreme joint stress, unstable rotation, and suboptimal body control increase the risk of injury in these movements. Each movement displays specific biomechanical patterns associated with particular injuries, for example, excessive pressure on the ankle and knee during push-offs and landings in somersault-type maneuvers. Conclusion. Biomechanical factors play a crucial role in the heightened risk of injury during fundamental floor gymnastics movements. The study concluded that a thorough understanding of floor gymnastics biomechanics can help athletes and coaches identify safer techniques and design training programs that minimize injury risk. Recommendations include prioritizing biomechanical training and proper landing techniques to reduce joint stress. Further research is needed to refine biomechanical analysis and explore more effective injury prevention strategies aimed at enhancing safety in floor gymnastics.

Full textAbstract:
The judicial systems of the United States and Canada very frequently utilize expert witnesses in engineering as well as most disciplines of science. Only in the last three decades biomechanists have been recognized and admitted to the courts as expert witnesses to provide opinions in the forensic biomechanics field. Thanks to the efforts of a few individuals, the science of biomechanics is now well accepted by the officers of the court systems of North America. Biomechanists possess the combined knowledge of engineering mechanics, biology, human anatomy, and physiology that makes it possible for them to reconstruct and analyze accidents of all kinds. In spite of the fact that the most obvious utilization of forensic biomechanics is in the area of analyses of injury mechanisms associated with motor vehicle accidents, there are other areas such as occupational, sports and recreational, slip/trip and fall accidents, and various product liability cases where forensic biomechanics expertise is required. In this paper, one litigation case is presented with some technical details and several other cases from different areas are briefly outlined. Because of obvious reasons, cases are presented in a generic format without referring to a particular company or organization.

Full textAbstract:
The role of corneal biomechanics in laser vision correction (LVC) is currently being raised in the assessment of postoperative corneal ectasia risk. The aim of the paper was to evaluate the changes in corneal biomechanics after LVC procedures based on a systematic review of current studies. The results of a search of the literature in the PubMed, Science Direct, Google Scholar, and Web of Science databases were selected for final consideration according to the PRISMA 2020 flow diagram. Included in our review were 17 prospective clinical studies, with at least 6 months of follow-up time. Corneal biomechanical properties were assessed by Ocular Response Analyzer (ORA), or Corvis ST. The results of the study revealed the highest corneal biomechanics reduction after laser in situ keratomileusis (LASIK) followed by small incision lenticule extraction (SMILE) and surface procedures, such as photorefractive keratectomy (PRK) or laser-assisted sub-epithelial keratectomy (LASEK). In SMILE procedure treatment planning, the use of thicker caps preserves the corneal biomechanics. Similarly, reduction of flap thickness in LASIK surgery maintains the corneal biomechanical strength. Future prospective clinical trials with standardization of the study groups and surgical parameters are needed to confirm the results of the current review.

Full textAbstract:
The mechanics, morphometry, and geometry of our joints, segments, and muscles are fundamental biomechanical properties intrinsic to human neural control. The goal of our study was to investigate whether the biomechanical actions of individual neck muscles predict their neural control. Specifically, we compared the moment direction and variability produced by electrical stimulation of a neck muscle (biomechanics) to the preferred activation direction and variability (neural control). Subjects sat upright with their head fixed to a six-axis load cell and their torso restrained. Indwelling wire electrodes were placed into the sternocleidomastoid (SCM), splenius capitis (SPL), and semispinalis capitis (SSC) muscles. The electrically stimulated direction was defined as the moment direction produced when a current (2–19 mA) was passed through each muscle’s electrodes. Preferred activation direction was defined as the vector sum of the spatial tuning curve built from root mean squared electromyogram when subjects produced isometric moments at 7.5% and 15% of their maximum voluntary contraction (MVC) in 26 three-dimensional directions. The spatial tuning curves at 15% MVC were well defined (unimodal, P < 0.05), and their preferred directions were 23°, 39°, and 21° different from their electrically stimulated directions for the SCM, SPL, and SSC, respectively ( P < 0.05). Intrasubject variability was smaller in electrically stimulated moment directions compared with voluntary preferred directions, and intrasubject variability decreased with increased activation levels. Our findings show that the neural control of neck muscles is not based solely on optimizing individual muscle biomechanics but, as activation increases, biomechanical constraints in part dictate the activation of synergistic neck muscles. NEW & NOTEWORTHY Biomechanics are an intrinsic part of human neural control. In this study, we found that the biomechanics of individual neck muscles cannot fully predict their neural control. Consequently, physiologically based computational neck muscle controllers cannot calculate muscle activation schemes based on the isolated biomechanics of muscles. Furthermore, by measuring biomechanics we showed that the intrasubject variability of the neural control was lower for electrical vs. voluntary activation of the neck muscles.

Furniture as a functional object must satisfy both artistic and scientific requirements. In particular, ergonomic factors are very important in furniture design in terms of human health and productivity. To make furniture designs at the ideal intersection of science and art, it is necessary to approach furniture design with a scientific systematic. Accordingly, this paper summarizes and analyzes the current state of biomechanics in ergonomic furniture design, covering an overview of the biomechanics utilized in different types of furniture design, biomechanical analysis, and testing methods. In the conclusion of the study, the literature analysis identifies the key topics and areas of future exploration regarding the use of biomechanics in ergonomic furniture design. The findings of the review indicate that (1) the primary studies on biomechanics used in furniture design concentrate on special furniture, such as wheelchairs and transportation vehicle seats, with minimal investigation performed on common furniture; (2) mechanical analysis, experimental testing, and computer-aided ergonomics represent the main techniques applied in furniture design biomechanics; (3) the reliability of biomechanics used in furniture design needs to be improved due to the lack of fundamental parameters of the muscles and skeleton of the human body; and (4) more attention should be paid to the use of biomechanics in the design of common furniture, such as household and office furniture, which affects people’s health and comfort. The scientific and rational application of biomechanics should be integrated into ergonomic furniture design to promote healthy living and enhance work efficiency.

Full textAbstract:
Context: Patellofemoral pain (PFP) is often categorized by researchers and clinicians using subjective self-reported PFP characteristics; however, this practice might mask important differences in movement biomechanics between PFP patients. Objective: To determine whether biomechanical differences exist during a high-demand multiplanar movement task for PFP patients with similar self-reported PFP characteristics but different quadriceps activation levels. Design: Cross-sectional design. Setting: Biomechanics laboratory. Participants: A total of 15 quadriceps deficient and 15 quadriceps functional (QF) PFP patients with similar self-reported PFP characteristics. Intervention: In total, 5 trials of a high-demand multiplanar land, cut, and jump movement task were performed. Main Outcome Measures: Biomechanics were compared at each percentile of the ground contact phase of the movement task (α = .05) between the quadriceps deficient and QF groups. Biomechanical variables included (1) whole-body center of mass, trunk, hip, knee, and ankle kinematics; (2) hip, knee, and ankle kinetics; and (3) ground reaction forces. Results: The QF patients exhibited increased ground reaction force, joint torque, and movement, relative to the quadriceps deficient patients. The QF patients exhibited: (1) up to 90, 60, and 35 N more vertical, posterior, and medial ground reaction force at various times of the ground contact phase; (2) up to 4° more knee flexion during ground contact and up to 4° more plantarflexion and hip extension during the latter parts of ground contact; and (3) up to 26, 21, and 48 N·m more plantarflexion, knee extension, and hip extension torque, respectively, at various times of ground contact. Conclusions: PFP patients with similar self-reported PFP characteristics exhibit different movement biomechanics, and these differences depend upon quadriceps activation levels. These differences are important because movement biomechanics affect injury risk and athletic performance. In addition, these biomechanical differences indicate that different therapeutic interventions may be needed for PFP patients with similar self-reported PFP characteristics.

Full textAbstract:
Abnormal colorectal biomechanics and mechanotransduction associate with an array of gastrointestinal diseases, including inflammatory bowel disease, irritable bowel syndrome, diverticula disease, anorectal disorders, ileus, and chronic constipation. Visceral pain, principally evoked from mechanical distension, has a unique biomechanical component that plays a critical role in mechanotransduction, the process of encoding mechanical stimuli to the colorectum by sensory afferents. To fully understand the underlying mechanisms of visceral mechanical neural encoding demands focused attention on the macro- and micro-mechanics of colon tissue. Motivated by biomechanical experiments on the colon and rectum, increasing efforts focus on developing constitutive frameworks to interpret and predict the anisotropic and nonlinear biomechanical behaviors of the multilayered colorectum. We will review the current literature on computational modeling of the colon and rectum as well as the mechanical neural encoding by stretch sensitive afferent endings, and then highlight our recent advances in these areas. Current models provide insight into organ- and tissue-level biomechanics as well as the stretch-sensitive afferent endings of colorectal tissues yet an important challenge in modeling theory remains. The research community has not connected the biomechanical models to those of mechanosensitive nerve endings to create a cohesive multiscale framework for predicting mechanotransduction from organ-level biomechanics.

This paper examines the critical intersection of biomechanics and hydrodynamics in swimming, focusing on how biomechanical analysis enhances performance and minimizes injury risks. It traces the historical evolution of swimming techniques from utilitarian practices to scientifically informed methods, emphasizing recent technological advancements such as 3D motion capture and computational fluid dynamics. The analysis of stroke-specific biomechanics across various swimming styles—freestyle, breaststroke, backstroke, and butterfly—reveals the unique biomechanical considerations essential for optimizing efficiency. Additionally, the prevalence of shoulder injuries among swimmers is addressed, highlighting the importance of injury prevention strategies, including the correction of stroke flaws and the enhancement of shoulder stability through targeted rehabilitation exercises. The integration of real-time feedback and video analysis during training is proposed as a vital tool for improving technique and safeguarding swimmer health. Ultimately, this review underscores the essential role of biomechanics in enhancing athletic performance and ensuring the long-term wellbeing of swimmers across all levels of competition.

Journal of Athletic Training 52, no. 8 (August 1, 2017): 738–46. http://dx.doi.org/10.4085/1062-6050-52.5.03.
Full textAbstract:
Context: The extent to which lower extremity lean mass (LELM) relative to total body mass influences one's ability to maintain safe landing biomechanics during prolonged exercise when injury incidence increases is unknown. Objectives: To examine the influence of LELM on (1) pre-exercise lower extremity biomechanics and (2) changes in biomechanics during an intermittent exercise protocol (IEP) and (3) determine whether these relationships differ by sex. We hypothesized that less LELM would predict higher-risk baseline biomechanics and greater changes toward higher-risk biomechanics during the IEP. Design: Cohort study. Setting: Controlled laboratory. Patients or Other Participants: A total of 59 athletes (30 men: age = 20.3 ± 2.0 years, height = 1.79 ± 0.05 m, mass = 75.2 ± 7.2 kg; 29 women: age = 20.6 ± 2.3 years, height = 1.67 ± 0.08 m, mass = 61.8 ± 9.0 kg) participated. Intervention(s): Before completing an individualized 90-minute IEP designed to mimic a soccer match, participants underwent dual-energy x-ray absorptiometry testing for LELM. Main Outcome Measure(s): Three-dimensional lower extremity biomechanics were measured during drop-jump landings before the IEP and every 15 minutes thereafter. A previously reported principal components analysis reduced 40 biomechanical variables to 11 factors. Hierarchical linear modeling analysis then determined the extent to which sex and LELM predicted the baseline score and the change in each factor over time. Results: Lower extremity lean mass did not influence baseline biomechanics or the changes over time. Sex influenced the biomechanical factor representing knee loading at baseline (P = .04) and the changes in the anterior cruciate ligament–loading factor over time (P = .03). The LELM had an additional influence only on women who possessed less LELM (P = .03 and .02, respectively). Conclusions: Lower extremity lean mass influenced knee loading during landing in women but not in men. The effect appeared to be stronger in women with less LELM. Continually decreasing knee loading over time may reflect a strategy chosen to avoid injury. A minimal threshold of LELM may be needed to safely perform landing maneuvers, especially during prolonged exercise when the injury risk increases.

Full textAbstract:
Pianists, who attend to the integral relationship of their particular musculoskeletal characteristics to the piano technique at hand, discover an efficient path to technical advancement and, consequently, to injury prevention. Thus, a study of pianist's hand biomechanics in relation to different piano techniques is highly relevant, as hand features may influence various techniques in different ways. This study addressed relationships between pianists' hand biomechanics and the performance of a scale in thirds, as a part of an ongoing series of studies examining relationships between hand biomechanics and performance data of primary techniques. The biomechanics of hand length and width, finger length, hand span, hand and arm weights, and ulnar deviation at the wrist were compared with tempo, articulation, and dynamic voicing (tone balance between two notes of the thirds). Pearson correlation analysis showed a positive association between ulnar deviation and tempo; the other biomechanical features showed no relationships with any of the performance criteria. Qualitative cross-sectional observation of individual profiles showed that experienced pianists perform with a higher degree of synchrony in two-note descent while pianists with organ training background play with a lesser degree of synchrony. All biomechanical features were closely related among one another with one exception: wrist ulnar deviation was not associated with any other biomechanical features; rather, data suggest possible negative associations. This study underscores the importance of wrist mobility in piano skills development. Further research using a complete set of prototype piano techniques and multiple-level pianist-subjects could provide substantive biomechanical information that may be used to develop efficient pedagogy and prevention strategies for playing-related injuries as well as rehabilitation.

Full textAbstract:
Describing body size (anthropometry) and physical properties of the body (biomechanics) are areas of interest both in research and in application. The human factors engineer needs anthropometric and biomechanical information primarily for designing the operator/equipment interface. Available information is piecemeal, incomplete, and often not compatible since researched and provided in various scientific disciplines. However, even the researcher is hindered by the “scatter” of data, measuring techniques, and research objectives. Hence, an effort to standardize in the areas of anthropometry and biomechanics would, if done properly, help both scientists and engineers.

Full textAbstract:
It is possible to improve neuronavigation during image-guided surgery by warping the high-quality preoperative brain images so that they correspond with the current intraoperative configuration of the brain. In this paper, the accuracy of registration results obtained using comprehensive biomechanical models is compared with the accuracy of rigid registration, the technology currently available to patients. This comparison allows investigation into whether biomechanical modeling provides good-quality image data for neuronavigation for a larger proportion of patients than rigid registration. Preoperative images for 33 neurosurgery cases were warped onto their respective intraoperative configurations using both the biomechanics-based method and rigid registration. The Hausdorff distance–based evaluation process, which measures the difference between images, was used to quantify the performance of both registration methods. A statistical test for difference in proportions was conducted to evaluate the null hypothesis that the proportion of patients for whom improved neuronavigation can be achieved is the same for rigid and biomechanics-based registration. The null hypothesis was confidently rejected (p < 10−4). Even the modified hypothesis that fewer than 25% of patients would benefit from the use of biomechanics-based registration was rejected at a significance level of 5% (p = 0.02). The biomechanics-based method proved particularly effective in cases demonstrating large craniotomy-induced brain deformations. The outcome of this analysis suggests that nonlinear biomechanics-based methods are beneficial to a large proportion of patients and can be considered for use in the operating theater as a possible means of improving neuronavigation and surgical outcomes.

Research Objectives: This study aims to analyze the role of biomechanics in improving volleyball service performance in Jakarta Pertamina club athletes. Specifically, the study investigates the relationship between biomechanical principles and service effectiveness, as well as identifying key biomechanical factors that contribute to improved service speed and accuracy. Methods: This quantitative study involved 30 volleyball athletes from Pertamina's Jakarta club. Data was collected through video analysis of service movements with high-speed cameras, anthropometric measurements, and service speed and accuracy tests. Biomechanical analysis is performed using special software to measure joint angle, angular velocity, and forces generated during service phases. Statistical analysis uses multiple regression and Pearson correlation tests to determine the relationship between biomechanical variables and service performance. Results: The results showed a significant positive correlation between knee flexion angle (r = 0.78, p < 0.01) and shoulder rotation (r = 0.82, p < 0.01) with service ball speed. Regression analysis revealed that a combination of biomechanical factors, including arm angular velocity, ball release angle, and momentum transfer from foot to arm, contributed by 76% to the variation in serve speed (R² = 0.76, p < 0.001). Improvements in techniques based on biomechanical principles resulted in an average increase in service speed of 15% and accuracy of 22%. Conclusion: This study confirms the important role of biomechanics in improving volleyball service performance. Understanding and applying the principles of biomechanics in training can significantly improve the speed and accuracy of an athlete's serve. These results provide a scientific basis for the development of more effective and personalized training programs for volleyball athletes.

Research purpose: To explore the influence of dance training and creation methods based on the combination of biomechanics and artificial intelligence (AI) technology on dance expression, biomechanics indicators and subjective satisfaction of dancers, to promote the modern development of dance art, and to optimize the dance education and training methods. Study method: A control experiment was designed, and then the subjects were divided into experimental group and control group. The experimental group adopted the dance training and creation method based on the combination of biomechanics and AI technology, while the control group adopted the traditional dance training and creation method. During the experiment, the biomechanical data of the dancers were collected using the 3D motion capture system and EMG measurement equipment, and the AI model was developed for data analysis and training guidance. Study content: The experiment involved the assessment of dance performance, the comparison of biomechanical indicators, and the subjective satisfaction survey of dancers. Rate the dance works, evaluate the innovation of dance movements, the depth of emotional expression, etc., use advanced equipment to measure the biomechanical indicators of peak joint strength and muscle fatigue, and understand the feelings and opinions of dancers on the experiment through questionnaire and interview. Results: The experimental group showed obvious advantages in dance performance, biomechanics, and subjective satisfaction of dancers. Dance works are equally expressive. All scores were significantly higher than the control group, peak joint stress was relatively low, muscle fatigue increased slowly, and dancer satisfaction scores also were significantly higher.

The prevalence of prosthodontic treatment has been well recognized, and the need is continuously increasing with the ageing population. While the oral mucosa plays a critical role in the treatment outcome, the associated biomechanics is not yet fully understood. Using the literature available, this paper provides a critical review on four aspects of mucosal biomechanics, including static, dynamic, volumetric and interactive responses, which are interpreted by its elasticity, viscosity/permeability, apparent Poisson's ratio and friction coefficient, respectively. Both empirical studies and numerical models are analysed and compared to gain anatomical and physiological insights. Furthermore, the clinical applications of such biomechanical knowledge on the mucosa are explored to address some critical concerns, including stimuli for tissue remodelling (interstitial hydrostatic pressure), pressure–pain thresholds, tissue displaceability and residual bone resorption. Through this review, the state of the art in mucosal biomechanics and their clinical implications are discussed for future research interests, including clinical applications, computational modelling, design optimization and prosthetic fabrication.

As biomechanics advances, understanding the structural and functional dynamics of biological systems at molecular and cellular levels becomes increasingly critical. This study investigates a biomechanical framework for analyzing cellular interaction forces and information flow in mechanotransduction processes. Leveraging Data Mining (DM) technology, we evaluate cellular system efficiency and adaptation mechanisms under varying biomechanical stimuli, simulating stress conditions akin to high parallel processing loads. The proposed algorithm achieves an accuracy of 95.27% in predicting cellular response behaviors, with system stability maintained above 90% under simulated mechanical stress. These findings highlight the potential of computational methods to enhance our understanding of cellular resilience and adaptation in biomechanical contexts. Ultimately, this work contributes to the development of robust, adaptive models for studying the mechanobiology of cells and tissues, advancing diagnostic and therapeutic approaches in molecular and cellular biomechanics.

The field of sports biomechanics employs concepts from physics, biology, and engineering to investigate the mechanical characteristics of human motion and how they affect the body’s anatomy and functions. With the development of technology, sports biomechanics has emerged as a crucial component of sports medicine, training, and rehabilitation. To reduce the risk of injury and enhance athletic performance, sports biomechanics examines motions in sports in great length. The purpose of the study is to establish injury prevention and rehabilitation strategies for physical education (PE) teaching based on biomechanical characteristics. The early warning mode of sports injuries is recognized using advanced deep learning (DL) techniques, specifically resilient convolutional neural networks (RCNN). Biomechanical data from wearable sensors is used in this study to find trends related to sports-related injuries. A questionnaire survey of 228 students from various colleges was conducted. Individualized rehabilitation strategies will be provided to injured participants, taking into account their unique biomechanical deficiencies. These programs will be created in conjunction with physical therapists, and they will be updated in response to the patient’s progress toward recovery. The study found that their sports injuries were acute and chronic. This research demonstrated the treatment, prevention, and rehabilitation strategies of injuries in sports. The study emphasizes that biomechanical analysis is crucial for improving PE programs, which will eventually enhance students’ performance and overall health.

Full textAbstract:
Optical properties of the cornea are responsible for correct vision; the ultrastructure allows optical transparency, and the biomechanical properties govern the shape, elasticity, or stiffness of the cornea, affecting ocular integrity and intraocular pressure. Therefore, the optical aberrations, corneal transparency, structure, and biomechanics play a fundamental role in the optical quality of human vision, ocular health, and refractive surgery outcomes. However, the inter-relationships of those properties are not yet reported at a macroscopic scale within the hierarchical structure of the cornea. This work explores the relationships between the biomechanics, structure, and optical properties (corneal aberrations and optical density) at a macro-structural level of the cornea through dual Placido–Scheimpflug imaging and air-puff tonometry systems in a healthy young adult population. Results showed correlation between optical transparency, corneal macrostructure, and biomechanics, whereas corneal aberrations and in particular spherical terms remained independent. A compensation mechanism for the spherical aberration is proposed through corneal shape and biomechanics.

Biomechanics plays a pivotal role in enhancing athletic performance by analyzing and optimizing the mechanical aspects of human movement. This interdisciplinary field combines principles of physics, physiology, and engineering to assess how athletes move, generate force, and interact with their environment. Through biomechanical analysis, athletes and coaches can identify inefficiencies, prevent injuries, and improve technique, ultimately leading to superior performance. Key areas of focus include optimizing posture, movement patterns, joint angles, force production, and the application of external tools or equipment. Advances in motion capture technology, wearable sensors, and computer modeling have allowed for more precise assessments and individualized interventions. This paper explores how biomechanics contributes to maximizing athletic potential across various sports, discusses the role of biomechanics in injury prevention, and highlights emerging trends such as the integration of artificial intelligence and machine learning in sports science. Ultimately, a deeper understanding of biomechanics can provide athletes with the tools needed to push the boundaries of human performance while minimizing the risk of injury.

This paper explores the application of AI technology in the field of English essay grading, inspired by biomechanics. Biomechanics, which studies the mechanical aspects of biological systems, offers unique insights that can be analogously applied to the grading of English compositions. Just as biomechanics analyzes the complex structures and functions of biological entities by understanding the relationships between different components, we focus on natural language processing (NLP) and machine learning algorithms, with the primary objective is to analyze how these advanced technologies, inspired by biomechanical concepts, can enhance the accuracy, efficiency, and objectivity of grading English compositions. By employing various NLP techniques such as lexical analysis, syntactic parsing, and semantic understanding, combined with machine learning models for classification and regression, the study demonstrates significant improvements in grading performance. The findings indicate that AI-powered systems, inspired by biomechanics, can provide consistent and reliable evaluations, thus offering valuable support to educators and students alike.

Full textAbstract:
In recent years, under the theme of vigorously promoting traditional Chinese culture in China, original picture books of traditional Chinese culture have ushered in development opportunities, and a variety of original children’s picture books of traditional culture have come onto the market in a variety of ways. Based on this, this paper explores the path of original picture book content creation from a cultural perspective. It introduces the origins and development of original picture books, as well as the methods and key points of content creation. It analyses the problems of creating original picture books based on a cultural perspective, including traditional story themes, the homogenisation of painting styles and the disconnect between creative content and modern life. Moreover, this paper extends its exploration by integrating biomechanics. Strategies for creating content for original picture books based on a cultural perspective are proposed, including combining tradition with fun, establishing the creator’s own unique style, and selecting stories that are drawn in line with modern education, but also integrating biomechanical knowledge. For example, accurately depicting the biomechanics of character movements to enhance authenticity, endowing cultural symbols with biomechanical - based meanings, and creating interactive experiences related to biomechanics. By incorporating biomechanics, picture books can offer readers a more immersive and educational experience. This paper aims to provide references and lessons for the creation of content for original picture books.

The ideological and political education (IPE) ecosystem in universities is not only an essential component of the broader educational ecosystem but also a microcosm of it. In an era that emphasizes ecology and sustainability, integrating the concepts of the biomechanics field into the ecological environment of IPE in universities holds significant practical implications. Biomechanics, a discipline dedicated to studying the mechanical behavior of organisms, has a profound impact on aspects such as the ecological environment and human health. From the perspective of ecological philosophy, the ecological environment of IPE in universities should fully consider the sustainable development of biomechanical technologies and their influence on human health. This paper presents a dynamic early warning system for IPE in universities based on an improved Support Vector Machine (SVM) algorithm. This system aims to optimize the IPE model and enhance educational effectiveness while incorporating concepts related to biomechanics. We have constructed an evaluation index system for the quality of IPE in universities across five dimensions: basic quality, teaching attitude, teaching method, teaching ability, and teaching effect. These indicators are evaluated through expert scoring to generate a comprehensive assessment of the teaching quality of IPE. Taking into account the close connection between human mechanical responses and the ecological environment in the field of biomechanics, during the evaluation process, we incorporate the impact of the ecological environment on the human biomechanical state (such as bone development and muscle function) into consideration. This approach guides students to establish a correct ecological view and understanding of biomechanical technologies. Model simulations and performance verifications show that the fuzzy neural network undergoes 779 training iterations, with a training target set at 0.05 and a learning rate of 0.09. This model demonstrates a strong ability to provide comprehensive dynamic early warnings for IPE in universities. It has obvious advantages in adaptability, model fitting accuracy, and processing efficiency in the face of information overload, contributing to the continuous development of IPE in universities from the integrated perspective of ecological philosophy and biomechanics.
