Abstract:
Translation into English has recently been completed for excerpts on ear and craniofacial anthropometry from an innovative, unpublished Bulgarian-language doctoral thesis written in 1986 by a plastic surgeon, M. M. Madzharov, MD-PhD; MD-SC. Most remarkable among the many benefits of the translation was revelation of heretofore unavailable text descriptions for 49 dimensions. Of these, 43 explain the titles and abbreviations with summary statistical data on ear measurements for young adults that were published in 1989 in the English language. Especially valuable among these data were four new and unique, long-axial ear lengths, all measured from a common ear landmark. These could locate “station planes” for cross-section views of human ears, similar to those for 3-D coordinate systems in aircraft and spacecraft fuselage engineering. Examples explaining the concepts and values of such a new approach to ear anthropometry are herein introduced, described and illustrated, together with previously recommended improvements in ear anthropometry notation and illustration, a virtual Ear Primary View Plane, a section plane through the ear long axis, newly introduced “semi-width” measurements extending perpendicular to the aforementioned section plane, new concepts of “view depths,” which are measured perpendicularly from the Ear Primary View Plane toward ear surfaces and a previously described three-axis aircraft motion analogy for defining static ear orientation. These innovative approaches are advocated for adoption by future researchers, designers of related hardware, modelers and standards developers.

Abstract:
New hardware technological developments have broadened the scope of anthropometric research by allowing easier, more precise and more comprehensive collection of quantitative information in three–dimensional (3D) form. This information will provide better design and evaluation information for protective equipment and clothing, better modelling information for workspace design, and more accurate information for the biomechanical evaluation of designs. In addition, the ability to identify the surface more precisely allows for the investigation of relationships, in numerical form, between surface and subsurface anatomy on living people. This could have clinical as well as research application. The goal of this session is to provide a forum for exchange of information on the new developments, research and application in the area of 3D anthropometry. One paper presented here discusses devices available for 3D data collection, and their pros and cons for various applications. Also discussed is the new statistical and graphical technology needed for understanding and use of the huge collections of information which result with 3D data collection, as well as methods used in 3D modelling and examples of current 3D research efforts.

Abstract:
Purpose The determinants of physical fitness in children have been given limited attention. In particular, the relative role of chronological age, sex, anthropometry, and body composition in physical fitness of children has been barely investigated. This cross-sectional study investigated determinants of physical fitness using a set of predictive variables including, in addition to chronological age and sex, a large panel of anthropometric measurements as well as body composition. The study was carried out in a convenience sample of children aged 6–12 participating in a summer camp. Methods One-hundred-ninety-three children (128 males) fulfilled all requirements and entered analysis. Health-related physical fitness components (speed, muscular power and balance) were explored by means of field tests, namely the 30-m dash test for running speed, the standing long jump and the seated chest pass test for lower limbs and upper body muscular power, respectively, and the flamingo balance test for static balance. Determinants of physical fitness were investigated by regression analysis using chronological age, sex, anthropometry, and body composition in a hierarchical approach. To minimize the expected effect of collinearity in predictor variables, an original statistical approach using Random Forests analysis was adopted. Results Age predicted 45.2%, 43.6%, 35.6% and 25.6%; and sex 9.5%, 10.7%, 6.3% and 2.0% of variance in the 30-m dash, seated chest pass, standing long jump, and flamingo balance test, respectively. Anthropometry and body composition explained a limited or no percentage of variance. The adjusted R2 (root mean square error) was 0.61 (0.31 s), 0.45 (0.32 m), 0.58 (0.15 m) and 0.41 (0.75 logs) for the 30-m dash, seated chest pass, standing long jump, and flamingo balance test, respectively making these models useful when physical fitness tests are not feasible. Conclusions We highlighted the respective role of chronological age, sex, anthropometry, and body composition in physical fitness of children in the wide age range 6–12 years. Data confirm and expand on previous literature by showing with a strictly conservative statistical approach that chronological age is a main determinant of physical fitness of both boys and girls, sex playing a limited role. The role of anthropometry was even less important, and no role was found for body composition. These findings should be considered when planning/implementing motor development or physical education programs.

Abstract:
Purpose of the study: To register the dynamics of the basic parameters of the physical development of children from the fourth preparatory group, as a result of the implementation of an enriched educational content in physical culture pedagogical situations. 54 girls and 67 boys were investigated and measured twice – at the beginning and at the end of the pedagogical experiment. Anthropometric parameters assessed: height, body weight, chest circumference. Methods: Theoretical analysis, pedagogical experiment, anthropometry, statistical methods. Results: Height: the highest increase in that parameter was found in the Experimental Group of boys and the smallest one – in girls of the Control group. Body weight: boys from the EG showed the highest increase, while the lowest one was found in boys from CG. Chest circumference: the greatest increase was measured in CG of, while the smallest one in the EG of girls. In conclusion, we can underline that the changes in the anthropometric parameters are due both to the laws of biological developments of children at that age, as well as to the applied enriched educational content.

Abstract:
Multiple anthropometric equations have been developed aiming to provide accurate and affordable assessment of body fat composition in male athletes. This study examined correlations of values obtained from seventeen different anthropometric equations to DXA as well as BIA and DXA values. Male athletes ( n = 101 ) from three different combat sports, wrestling ( n = 33 ), judo ( n = 35 ), and kickboxing ( n = 33 ), with an average age of 20.9 ± 4.2 were included. Body fat percentage was estimated using anthropometry, BIA, and DXA. Correlations between anthropometric methods and DXA, as well as BIA and DXA, were determined using Spearman’s rank correlation. Sixteen out of seventeen estimates of body fat percentages using existing anthropometric equations showed strong positive correlation with the values derived from DXA measurements ( r = 0.569 − 0.909 ). The highest correlation was observed using the equation derived by Yuhasz, r = 0.909 , followed by the equations from Oliver et al., Evans et al., Faulkner, and Thorland et al. ( r ≈ 0.9 ). Statistical analysis of body fat percentages from DXA and BIA measurements also showed high positive correlation ( r = 0.710 ). Correlation of seventeen anthropometric equations with BIA and DXA methods revealed that equations by Yuhasz, Oliver et al., Evans et al., Faulkner, and Thorland et al. are suitable alternative for assessing body fat percentage among male athletes from combat sports, showing even stronger correlation than BIA method.

Abstract Introduction. Neonatal anthropometric measurements, including body weight, length, head circumference and abdominal circumference are routine procedures in obstetric and neonatal departments. Standard values for neonatal population are established for body weight, length, head and thoracic circumference, however there are no reference values for neonatal abdominal circumference, futhermore, this measurement currently is not a routine procedure in every obstetric and neonatal unit. In order to evaluate the increase of abdominal circumference in newborns with a disease of organs of abdominal cavity including necrotizing enterocolitis (NEC), the abdominal girth of newborns soon after birth without pathology in the abdominal cavity should be ascertained. Thereby, the average value of the abdominal circumference of newborns in Latvia could be obtained. Aim of the Study. The aim of our study is to measure the abdominal circumference in premature and term-born neonates soon after birth and to define the correlation between abdominal circuit and birth weight. Materials and Methods. The measurement of waist girth was carried out in 460 neonates within 30 minutes after birth. Newborns were divided into 4 groups according to birth weight: extremely low birth weight (ELBW) - under 1000 g, very low birth weight (VLBW) - 1001 g - 1500 g, low birth weight (LBW) - 1501 g - 2500 g and term neonates with 2501 g - 4590 g birth weight. The abdominal circumference was measured in 2 obstetric units in accordance with the previously established measurement methods. Results. There was no statistical difference between abdominal circumference in boys and girls in ELBW, VLBW and LBW groups (p>0.05). Mean abdominal circumference in ELBW group was 18,70 cm (SD=0,84) in boys and 18,67 cm (SD=1,40) in girls, VLBW group was 22,20 cm (SD=1,42) and 21,94 cm (SD=1,29) in boys and girls, respectively. Mean abdominal circumference in LBW group was 24.47 cm (SD=2.36) in boys, and 24.92 cm (SD=2.23) in girls. Independent Samples Test: Mean abdominal circumference was statistically different in boys and girls in 2500g -4590g birth weight group with median value 30.56 cm in boys, and 33.23 cm in girls (p<0,05). Mean value in girls was 3.33 cm higher than in boys. Dependent Variable linear regression: Specific formula for estimation of normal abdominal circumference was developed as a result of this study: y=0.0044x+16.38 (y - abdominal circumference, cm; x - body weight, grams; 0.0044 - regression coefficient; 16.38 - regression constant). Conclusions. The difference of mean abdominal circumference was not statistically significant in boys and girls in ELBW, VLBW and LBW groups, however, the difference was significant in the term-born neonates group. As a result of this study reference values and specific formula were established, which allows determination of normal abdominal circumference in neonates depending on birth weight.

Abstract:
AIM: To study the anatomical variability of the component composition of the body in adolescents in normal conditions, and in autonomic dysfunction syndrome (ADS), using anthropometry and bio-impedance analysis. MATERIALS AND METHODS: The study involved healthy adolescents and adolescents with ADS of the vagotonic, mixed and sympathicotonic types. The values of basic anthropometric (body length and weight, waist, and hips) and bio-impedance metric values (absolute and relative values of fatty, lean, musculoskeletal, and active cell masses) were obtained. The Quetelet index (BMI), and waist-hip index were calculated. Statistical analysis of the data obtained was performed. RESULTS: Low values of anthropometric indicators, absolute values of fat, lean, musculoskeletal masses, and high values of active cell mass were observed in the group of adolescents with the vagotonic type of ADS compared to other groups of examined adolescents. High values of anthropometric indicators, absolute values of fat, lean, musculoskeletal masses, and low values of active cell mass were obtained in the group of adolescents with a sympathicotonic type of ADS. The values of the studied parameters in groups of healthy adolescents and adolescents with mixed-type ADS occupied an intermediate position compared to the groups with vagotonic and sympathicotonic types. CONCLUSIONS: Statistically significant differences in the values of the absolute and relative indicators characterizing the component composition of the body, were revealed in practically healthy adolescents and adolescents with various types of autonomic dysfunction syndrome.

Aim: The aim of the study was to investigate perceived family cohesion and adaptability and its association with trauma, malocclusion and anthropometry in school adolescents. Methods: Cross-sectional study with a representative sample of 921 adolescents from 13 to 19 years old of both sexes, enrolled in state public schools of a northeastern Brazilian municipality. A questionnaire with sociodemographic questions, the FACES III scale was applied and a clinical oral examination (dental trauma and malocclusion) and anthropometric (BMI by age) were performed. For statistical analysis, was evaluated by the Chi-square test. The variables that presented significance in the bivariate analysis of up to 25% were taken to the multivariate analysis (multinomial logistic regression), variables that presented significance in bivariate analysis of up to 25% were taken to multivariate analysis and all conclusions were drawn considering the significance level of 5%. Results: As a result, it was identified that displaced families were associated with low maternal education, agglutinated families associated with the absence of caries. Rigid families were associated with marked overjet and caries. The prevalence of dental trauma (37.5%) was considered high. Conclusion: It was concluded that family cohesion and adaptability were associated with oral health and socioeconomic factors.

Abstract:
Background: Diabetes places extra-burden on those affected with the condition particularly in resource constraint settings. Inaccessibility to affordable diagnostic procedures poses a major challenge to the assessment of cardiovascular status in patients with type-2 diabetes in resource limited settings. The study was aimed at evaluating some easily accessible biochemical markers and anthropometric indices implicated in cardiovascular disease amongst T2DM patients. Methods: One hundred and sixty (160) type-2 diabetic patients grouped into type-2 diabetes only as group 1, type-2 diabetic patients diagnosed with hypertension as group 2, and eighty (80) age and sex-matched controls as group 3, were enrolled in a cross-sectional pattern. Biochemical parameters were assayed using standard laboratory methods. Statistical analysis was performed using the Statistical Package for Social Sciences (SPSS) version 20.0 with statistical significance considered at p≤0.05. Results: The values obtained for diabetic groups were: Glycated Hemoglobin (HbA1c) 9.07±1.99, 10.15±4.98, Total Homocysteine (tHcy) 14.85±52.10, 28.35±100.35, high sensitivity C-reactive protein (hs-CRP) 6.72±6.78, 10.00±11.15, Waist Circumference, 92.58±1.55, 93.65±18.91, Hip Circumference, 96.87±9.01, 98.96±20.33, Systolic Blood Pressure, 113.50±12.94, 135.50±22.72, Diastolic Blood Pressure, 70.75±8.57, 75.38±12.62, Body Mass Index, 25.40±4.70, 26.93±6.50 (among patients) and HbA1c 5.81±0.86, tHcy 0.75±1.44, hs-CRP 5.30±6.19, Waist Circumference 83.15±10.69, Hip Circumference 93.50±22.05, Systolic Blood Pressure, 113.50±10.20, Diastolic Blood Pressure, 77.00±7.19, Body Mass Index, 24.84±4.93 (among controls). Conclusion: The assessment of some cardio metabolic markers and anthropometric indices may provide easy and accessible tools for prediction and assessment of cardiovascular disease in patients with T2DM especially in resource poor settings.

Abstract:
Background: Facial anthropometry is the scientific study of measurements and proportions of the human face. There is huge paucity in the metric measurements of face in Indian population. This study is involved in collecting facial anthropometric data of Western Uttar Pradesh population of age group between 18-25 years. Aims and Objectives: This study aims at evaluating predominant facial phenotype, using facial height and facial width of Western Uttar Pradesh population as study subjects. Materials and Methods: The study was conducted on 200 medical and paramedical students of Shri Ram Murti Smarak Institute of Medical Sciences (SRMS-IMS), Bareilly, Uttar Pradesh. The study subjects were of 18-25 year’s age, belonging to Western Uttar Pradesh region. Digital Vernier Caliper was used to measure the facial parameters. The data was analyzed using statistical tool SPSS 16.0 version. Results: In the present study it is found that facial height and width are more in males compared to females. This difference is statistically significant. On analyzing facial index, hyperleptoprosopic face is the predominant phenotype in males as well as in females, followed by leptoprosopic type in males and mesoprosopic type in females. However, gender differences in facial index are not statistically significant at p<0.05. Conclusion: The current study reveals that facial parameters can be used to determine the gender of an individual on the basis of height and width.

Abstract:
This is a study of the factors that affect face shapes, and the techniques that can be used to measure variations in two dimensional representations of faces. The materials included thirty photographs of people in natural poses and thirty portraits that were based on the pose photographs. Visual assessors were asked to score the photographs and portraits in terms of pose (cant, turn and pitch) and also to compare the portraits to the photographs and score them in terms of likeness in the depiction of the face and its component features. Anthropometric indices were derived and used to score the images for the pose variables as well as for aspects of individual variation in external face shape and the spatial arrangement of the features. Geometric morphometric analysis was also used to determine the shape variation occurring in the photographs, the variation within the portraits, and to specifically discern where the portraits differ from the photographs in the depiction of head pose and individual differences in facial morphology. For the analysis of pose it was found that visual assessors were best at discerning the extent of head turning and poorest at discerning head pitch. These tendencies occurred in the visual assessments of both the photographs and the portrait drawings. For the analysis of the individual variation in face shapes it was found that external face shape varies according to upper face dimensions and the shape of the chin, and that vertical featural configurations are strongly linked to external face shape. When the portrait and photograph data were placed in the same geometric morphometric analysis the inaccuracies in the portrait drawings became evident. When these findings were compared to the visual assessments it transpired that, on average, visual assessment was generally congruent with the geometric morphometric analysis, but were possibly confounded by patterns of dysmorphology in the portraits that were contrary to what this study suggests are normal patterns of face shape variation. Overall this study has demonstrated that while anthropometric and visual assessments of facial differences are quite good, both were comparatively poor at assessing head pitch and tended to be confounded by the dysmorphologies arising in the portrait drawings. Geometric morphometric analysis was found to be very powerful in discerning complex shape variations associated with head pose and individual differences in facial morphology, both within and between the photographs and portraits.

Abstract:
The appropriate normalization of exercise performance data for differences in body size underpins the clarification of growth and maturational influences on physiological function. Therefore, scaling is an issue of fundamental importance for all paediatric exercise scientists. The selection and application of a scaling method appropriate for the data and research question being addressed is at least as important as ensuring that the methodology used to collect the data is valid, reliable, and appropriate for use with young people. Several scaling methods are available and some methods can be applied in different ways. Unfortunately, taken as a whole, the extant literature presents a confusing picture as to which of these techniques is preferable, how they should be applied, and the meaning of the results obtained. The aim of this chapter is to clarify these issues through a description of the techniques available for analysing both cross-sectional and longitudinal data sets, highlighting their statistical and theoretical derivations.

Abstract:
The capabilities of virtual development of safety systems for occupant safety are increasing with the growth of acceptance, computational power and the usability of tools. Nevertheless, nowadays car safety systems are primarily developed using single statistical representations of humans, like the 5%-ile female or the 50%-ile male body. Hence variation of anthropometry existing in the real-world is only covered to a very limited extent. Recently, several studies developed fast calculating models using methods of rigid body simulation or metamodeling. They suggested investigating rapid or even near-real-time prediction-models for variations of outer parameters, such as airbag characteristics or crash pulse. In contrast, the proposed paper aims to get insight into the impact of human body variation on its crash behavior. This behavior can then be related to a model of a specific percentile. The objective of this approach is to run one simulation with a single representation of a human body and get data for deviated models based on previous simulations. Therefore, the main advantage of this concept is the reduction of the simulation time, needed to get all results of the occupants with different sizes (body mass index, statue, the ratio of sitting height and statue). To test the feasibility of the approach, a 2D rigid body system was created as a simplified model using LS-Dyna and Python. It represents a car's occupant who is restrained by a lap and shoulder belt under the influence of a crash pulse. The joint characteristics were modeled via spring, damper and friction definitions aiming for human-like behavior. To create a database, extensive simulations were carried out by varying the dimensions of body parts, applying a Latin-Hypercube Design Of Experiments scheme. The parameter limits were taken from UMTRI's human shape database. Since the minimal model provides a very limited set of reasonable assessment channels, only kinematic responses like maximum displacement and acceleration of the head and chest were evaluated. The obtained results seem to prove expected correlations between mass and maximum acceleration as well as forward displacement. For the model's training, different combinations of features and targets are tested. For example, the results from simulations with one body measure set are used as feature-vector, while the target-vector is formed by the kinematic characteristics of diverging human representations. After normalizing the data, various regression and machine learning algorithms were applied and their performance evaluated.

Abstract:
Anthropometric data are widely used in the design of chairs, seats, and other furniture intended for seated use. These data are valuable for determining the overall height, width, and depth of a chair, but contain little information about body shape that can be used to choose appropriate contours for backrests. A new method is presented for statistical modeling of three-dimensional torso shape for use in designing chairs and seats. Laser-scan data from a large-scale civilian anthropometric survey were extracted and analyzed using principal component analysis. Multivariate regression was applied to predict the average body shape as a function of overall anthropometric variables. For optimization applications, the statistical model can be exercised to randomly sample the space of torso shapes for automated virtual fitting trials. This approach also facilitates trade-off analyses and other the application of other design decision-making methods. Although seating is the specific example here, the method is generally applicable to other designing for human variability situations in which applicable body contour data are available.

Abstract:
ABSTRACT Worldwide, conducting systematic research and control of sports-competitive activities is a severe premise to a well-programmed and managed training process. An important part of control in sports is determining the level of physical development for each gender and age. The aim of the study was to determine the level of physical development in girls up to U12, U14 and U16. The survey was conducted in March - September 2021. The subject of research are the signs of physical development in girls up to U12, U14 and U16. The object of research are the main signs of physical development. 173 girls were studied, divided into three age groups. All participants are basketball players, registered in clubs in Bulgaria. Sports and pedagogical testing were conducted with the participants with the test battery, which includes 7 indicators. The applied research methods are: review study of the specialized literature and sports-pedagogical testing. Depending on the objectives of the study, the following statistical methods were applied: Descriptive statistics, One-way АNOVA and Comparative analysis by Student‘s t-test for independent samples. The results show that the age has a positive effect on the studied anthropometric characteristics. In the selection of girls up to U12, who practice basketball, we should make some corrections and select taller children. Girls from U14 are more overweight but are within the obesity norms for their age group. There is a selection problem in girls U16. There are no tall children, as desired in basketball, among the three groups.

Abstract:
Topicality of research is indicated by importance of somatic health level assessment of military personnel that is a basement for fulfilling military tactical tasks and developing future military career. Physical endurance capacities develop during military training and have impact to the body composition parameters, health capacity level. Medical specialists carried out the assessment of health capacity of military personnel annually. The aim of the study is to evaluate the somatic health and its components in military personnel group that includes cadets from 1st till 5th study year in National Defence Academy of Latvia. The evaluation of somatic health level carried out according H.L. Apanasenko methodology that is a complex approach taking in count anthropometric parameters, physiological measurements, and tests` results in standard physical exercises. The statistical methods were used for analysis of data in SPSS version 20. There are fixed statistically significant correlation between somatic health level and anthropometric parameters (body mass, body mass index value) as well physiological parameters (systolic blood pressure value, hand muscle force, pulmonary vital capacity). The significance of the results is that the level of somatic health level connects to the parameters of body composition and functional parameters. Physical endurance capacities are based on somatic health level assessment, individuals with higher body mass index level, with higher blood pressure parameters, with lower vital index value as well with, longer restoring interval after standard physical exercise had lower somatic health level value. The changes of somatic health level in study group showed the impact of military training duration that important for future military career.

Abstract:
Globalized marketplaces are necessitating the consideration of the needs of users from a variety of national and international regions. Relevant body dimensions are known to play a key role in influencing users’ physical interactions with products. The main challenge in designing these products is the unavailability of comprehensive anthropometric databases for detailed analyses and decision-making. This paper presents a new method to this end. Z-scores are computed for each body measure of every individual in a reference population; this can be any population for which a comprehensive database is available. Next, descriptive statistical information (e.g., means, standard deviations, by-percentile values) from numerous studies and surveys are used to estimate distributions of the required body dimensions. Finally, the z-score values from the reference population are utilized to sample from the aforementioned distributions in order to synthesize the requisite virtual target population of users. The z-score method is demonstrated in the context of two existing populations: U.S. military in the late 1980s (ANSUR) and Japanese youth from the early 1990s. Despite certain stated limitations, which are topics of future work in this line of research, the method is shown to be accurate, easy-to-apply, and robust in terms of underlying assumptions.

Abstract:
ABSTRACT Modern handball is characterized by high motor activity and high intensity of game actions, requiring the player to mobilize his physical, mental, and technical-tactical abilities to the limit. Naturally, this is possible only by maintaining a high level of conditioning abilities, which find external expression in the form of various movements. Objective - The present work is to investigate the relationship between some anthropometric parameters and conditioning abilities of adolescent handball players. The contingent of the study are 11-12-year-old handball players who participated in handball groups at HC “Lokomotiv” Gorna Oryahovitsa. Mathematical and statistical methods - variation and correlation analysis. The analysis of the obtained results for the anthropometric parameters of 11-12-year-old handball players shows that the individual units and segments are relatively uniform. This is due to the selection, as well as the development of the child’s organism. The established level of special motor fitness shows that the studied group is homogeneous in terms of the measured fitness indicators. The presence of certain fluctuations in the handball throw and 800 y ball tests is due to the still un-strengthened musculoskeletal system and the level of technical training.

Abstract:
ABSTRACT One of the major problems in strength and conditioning of volleyball is connected with development and control of the anaerobic capacity. At this point, the aim of the study is to research the significance and the possibility of evaluating the speed test that characterizes anaerobic capacity in volleyball. The tasks of the research are: To establish a correlation between speed tests with maximal and submaximal intensity; To determine the relationship between indicator that characterizes anaerobic capacity and speed abilities. The study group was 19 female volleyball players of the under-18 national team of Bulgaria. Methods: To determine the anaerobic capacity and the indicators that characterize it we used the Wingate laboratory test and anthropometric indicators. Field tests were measured through chronometry. The results of the test were further analyzed by statistical methods. Results: The data from the descriptive statistics define the study group as homogeneous. Variation coefficient vary from 3.47% to 17,85%. This is a reason to assume that the received correlation results would be reliable enough. The research identified a high correlation between the speed tests with maximal intensity and the two types of test with submaximal intensity (r = .714; r = .732) but the high and significant correlation between the height of the subjects and the shuttle running type 1 (r = .714) were basis to recommend implementation of the shuttle running type 2 as a field test that characterizes anaerobic abilities in female volleyball players. A negative correlation between the results in sprint tests and the Wingate test determined that better results of speed tests correspond to: higher relative minimal power; smaller power decrement and coefficient of fatigue. At the same, time moderate correlation between results in speed tests and peak power and a negative moderate correlation between speed tests and relative peak power could be interpreted as underdeveloped anaerobic capacity.
