A necessarily high standard for physical readiness in tactical environments is often accompanied by high incidences of injury due to overaccumulations of neuromuscular fatigue (NMF). To account for instances of overtraining stimulated by NMF, close monitoring of neuromuscular performance is warranted. Previously validated tests, such as the countermovement jump, are useful means for monitoring performance adaptations, resiliency to fatigue, and risk for injury. Performing such tests on force plates provides an understanding of the movement strategy used to obtain the resulting outcome (e.g., jump height). Further, force plates afford numerous objective tests that are valid and reliable for monitoring upper and lower extremity muscular strength and power (thus sensitive to NMF) with less fatiguing and safer methods than traditional one-repetition maximum assessments. Force plates provide numerous software and testing application options that can be applied to military’s training but, to be effective, requires the practitioners to have sufficient knowledge of their functions. Therefore, this review aims to explain the functions of force plate testing as well as current best practices for utilizing force plates in military settings and disseminate protocols for valid and reliable testing to collect key variables that translate to physical performance capacities.

Streszczenie:
Women athletes are more likely to tear their anterior cruciate ligament than their male counterparts. The female athlete has a complex system of steroid hormones that are continually changing. These sex hormones that fluctuate throughout each month may influence knee injuries, specifically the anterior cruciate ligament. The increased incidence in women is thought to be multifactorial, a combination of structural, anatomical, or biomechanical factors. The NCAA has reported that 75 percent of anterior cruciate ligament injuries are non-contact in competitive jumping or pivoting sports. In this study, the effects of the menstrual cycle on neuromuscular performance were investigated. Fifteen healthy females with regular menstrual cycles completed the various tests of this study for three phases of the menstrual cycle. All females were categorized as moderate or vigorous exercisers from an activity questionnaire. This study used a repeated measures experimental design; therefore, each participant served as her own control. The participants completed a series of two tests, including functional balance and fatigability. Each series was completed during three different phases of the menstrual cycle: menstruation, follicular and luteal. The participants used ovulation kits to predict the luteal phase. These phases were then verified through blood tests at each exercise session. The reaction time and balance test was performed with a BOSU wobble board placed on a force plate. A force platform was utilized to collect center of pressure data from the wobble board. The fatigue test protocol consisted of the participants performing in a pre-fatigue functional test, fatigue protocol and post-fatigue functional ability test. The functional test protocol consisted of two trials of four single-legged hop drills. It was hypothesized that all of the functional tests would have the greatest neuromuscular performance during the follicular phase of the menstrual cycle, and for all of the tests to have differences between the pre- and post-fatigue trials. However, there were no significant differences in the functional tests over the menstrual cycle. There were differences in fatigue in the forward hop and figure eight tests, but the affect of fatigue on performance did not differ across menstrual cycle phases.

No ciclismo, a relação hiperbólica entre intensidade de exercício e tempo de exaustão (tlim) apresenta uma potência crítica (PC) e uma quantidade constante de trabalho que pode ser realizado acima da PC (W ). Alguns pressupostos dessa relação ainda não foram completamente testados e/ou confirmados. Dessa forma, os objetivos da presente tese foram: 1) investigar o efeito de duas diferentes taxas de utilização de uma mesma fração da W na magnitude de fadiga neuromuscular (redução do torque muscular pico); 2) investigar o efeito de duas diferentes taxas de utilização de uma mesma fração da W no tlim de um exercício subsequente realizado no domínio severo. A amostra foi composta por 17 sujeitos saudáveis do sexo masculino (25,6 ± 3,7 anos) que participaram voluntariamente. Para atender ao primeiro objetivo, o torque muscular pico dos sujeitos foi determinado por meio de um sprint isocinético all-out (cadência fixa de 120 rpm) em uma condição controle e após dois testes de carga constante programados para depletar 70% W em 3 e 10 min, respectivamente. Em adição, para atender ao segundo objetivo, os sujeitos realizaram dois testes de carga constante programados para depletar 70% W em 3 e 10 min seguidos por um teste até a exaustão na carga correspondente à PC + 10 W. O torque muscular pico nos testes de 3 min (108 ± 19 N.m) e 10 min (112 ± 23 N.m) foi significantemente reduzido (p < 0,05) em comparação à condição controle (135 ± 20 N.m). Contudo, não houve diferença entre as duas condições experimentais (p > 0,05). Por outro lado, o tlim na carga correspondente à PC + 10 W foi mais longo após o teste de 3 min (15,8 ± 6,4 min) que após o teste de 10 min (10,0 ± 6,8 min). Assim, com base nos resultados encontrados, pode ser concluído que a fadiga neuromuscular no domínio severo é independente da taxa de utilização da W quando o trabalho realizado acima da PC é o mesmo. Contudo, o tlim de um exercício severo pode ser prolongado quando é realizado após uma alta taxa de depleção da W . Isso significa que a magnitude da W pode ser aumentada dependendo da amplitude de variação da carga acima da PC.

Abstract : During cycling exercise, power output and time to exhaustion (tlim) describe a hyperbolic relationship, with an asymptote known as critical power (CP) and a fixed amount of work that can be performed above the CP (W ). Some assumptions of this relationship have not yet been fully tested and/or confirmed. Therefore, the aims of this thesis were: to investigate the effect of two different rates of utilization of the same fraction of W on 1) the magnitude of neuromuscular fatigue (reduction of peak muscle torque); and on 2) a tlim performed within the severe-intensity domain immediately following the first part of exercise. 17 healthy male subjects (25.6 ± 3.7 years) volunteered to participate in this study. Peak muscle torque was determined through an allout isokinetic sprint (cadence fixed at 120 rpm) in a control condition and after two constant power output tests set to deplete 70% W in 3 and 10 min, respectively. In addition, the subjects performed two constant power output tests set to deplete 70% W in 3 and 10 min, respectively, followed by a constant test at CP + 10 W performed to exhaustion. Peak muscle torque was significantly reduced (p < 0.05) after 3 min (108 ± 19 N.m) and 10 min (112 ± 23 N.m) tests compared to the control condition (135 ± 20 N.m). However, there was no significant difference between the two experimental conditions (p > 0.05). On the other hand, the tlim at CP + 10 W was significantly longer (p > 0.05) after the 3 min test (15.8 ± 6.4 min) compared to after the 10 min test (10.0 ± 6.8 min). In conclusion, neuromuscular fatigue in the severe-intensity domain is independent of the rate of utilization of W when the same work is accumulated above the CP. However, the tlim within the severe-intensity domain can be prolonged when performed after a fast rate of utilization of W which means that the magnitude of W can be increased depending on the amplitude of power output variation above the CP.

Streszczenie:
With improving professionalism of sports around the world, the volume and frequency of training required for competitive performances at the elite level has increased concurrently. With this amplification in training load comes an increased need to closely monitor the associated fatigue responses, since maximising the adaptive response to training is also reliant on avoiding the negative consequences of excessive fatigue. The rationale for the experimental chapters in this thesis was established after considering survey responses regarding current best practice for monitoring fatigue in high performance sporting environments (Chapter 3). On the basis of the results, vertical jump assessments were selected for further investigation regarding their utility in determining neuromuscular fatigue responses. Outcomes from the subsequent series of studies aimed to provide practitioners working in high performance sport with guidelines for using vertical jumps to monitor athletic fatigue. The results from Chapter 4 indicate using the mean value of at least six jumps enhances the ability to detect small but practically important changes in performance from week to week. This study also highlighted large differences (4-6%) in morning and afternoon performance, indicating that the time of day performance is assessed needs to be accounted for when monitoring changes in jump performance. Chapter 5 explored the theory that the time of day effect observed in Chapter 4 can be explained by internal temperature differences. This theory was supported by demonstrating that an extended warm-up period can negate differences in jump performance in the morning and the afternoon. Researchers who are unable to standardise the time of day that assessment occurs are able, therefore, to control for performance differences by manipulating the warm-up protocols. The third study examined changes in vertical jump performance over a three month training period and produced several novel outcomes. A major finding was that unloaded jumps were more sensitive to neuromuscular fatigue during intensive training than loaded jumps (Chapter 6). Furthermore, this set of results showed that all subjects changed their jump technique via a reduction in the amplitude of the countermovement when they were highly fatigued. Using the same data, an analysis was performed to quantify individual differences in within-subject variation (Chapter 7) during normal and intensive training. These results provided the first indication that within-subject variability in vertical jump performance is substantially different between individuals and between different training phases, an important consideration for interpreting the practical importance of performance changes. In Chapter 8 the relationship between vertical jump performance and electrically elicited force of the knee extensors was examined to better understand the mechanism(s) of changes in jump performance associated with neuromuscular fatigue during intensive overload training. The results showed that the fatigue assessed by vertical jump performance was likely not only peripheral in origin as previously suggested by other authors. Further research is required to further understand the mechanisms of reduced performance during overload training, although the preliminary evidence presented implicates central mechanisms. To conclude the thesis, the findings presented in the experimental chapters are summarised, with a series of practical recommendations for using vertical jumps to monitor athletic fatigue presented.

Cross education is the phenomenon by which the untrained limb will experience a gain in strength following a unilateral resistance training program. However, little is known as to the underlying adaptation occurring in the untrained limb. Purpose: To examine the effect of dynamic unilateral resistance training on the strength and neuromuscular adaptations of both the trained and untrained legs. Methods: Eight previously untrained males (22.38±2.92 y, 1.73±0.08 m, 75.26±14.53 kg) completed a four-week unilateral resistance training program, while another eight untrained males (24.00±4.57 y, 1.84±0.05 m, 94.21±16.14 kg) served as controls. Isometric leg extension strength, leg press 1 repetition maximum (1RM), leg extension 1RM, root mean square of the maximal electromyographic amplitude (EMG), submaximal EMG, dynamic neuromuscular economy (NME) and the slope of NME-power output relationship were determined before and after training to assess the changes in strength and neuromuscular adaptations of the vastus lateralis (VL) and rectus femoris (RF) in both the trained and untrained legs. The unilateral resistance training program was conducted on the dominant leg (DOM) in the unilateral resistance training group (URT) and was compared to the dominant leg of the control group (CON). Cross education was measured in the nondominant leg (NON) for both groups. The unilateral resistance training program was completed three days per week for a total of twelve training sessions. Exercises included in the training program were unilateral leg press, unilateral leg extension, bilateral chest press and bilateral low row. All data was analyzed using one-way analysis of covariance of the post-testing values using the pre-testing values as the covariate. Further analysis of the EMG and NME data was performed using magnitude-based inferences. Results: The URT group improved their isometric (DOM:11.03%, NON:4.98%), leg press (DOM:77.63%, NON:64.88%) and leg extension (DOM:46.76%, NON:16.43%) strength after the four weeks of resistance training. There was no difference between the groups in isometric strength in the dominant (p=0.188) or nondominant (p=0.948) leg. For leg extension 1RM, there was a significant difference between groups in the dominant leg (p=0.018), but not the nondominant leg (p=0.482). However, there were significant group differences in both the dominant (p=0.003) and nondominant (p=0.034) leg for leg press 1RM. In terms of maximal EMG, the training groups improved in the vastus lateralis (DOM:29.81%, NON:31.44%) and rectus femoris (DOM:20.71%, NON:6.26%) individually, as well as in total EMG (DOM:24.78%, NON:17.57%). There was a Likely Positive or Very Likely Positive effect of unilateral resistance training on the changes in maximal EMG of the vastus lateralis and rectus femoris in both the dominant and nondominant legs. There was a Likely Positive effect of unilateral resistance training on the submaximal EMG of the dominant vastus lateralis at 75 and 125 watts. Conversely, in the rectus femoris, there was Unclear effects of unilateral resistance training on the submaximal EMG of the dominant leg. There was no consistent effect of unilateral resistance training on submaximal EMG values of the vastus lateralis in the nondominant leg. However, the rectus femoris in the nondominant leg experienced a Likely Positive effect of unilateral resistance training on submaximal EMG. NME improved in the URT group in the VL at 75 (DOM:9.73%, NON:13.42%), 100 (DOM:8.76%, NON:8.21%), and 125(DOM:24.26%, NON:12.8%) watts and in the RF at 75 (DOM:22.25%, NON:15.73%), 100(DOM:24.85%, NON:17.05%) and 125 (DOM:30.99%) watts. In terms of neuromuscular economy, there was a Likely Positive or Very Likely Positive effect of unilateral resistance training on most measures of NME on both the vastus lateralis and rectus femoris in both the dominant and nondominant legs. In terms of NME slope, there was only a Likely Positive effect of unilateral resistance training on the dominant vastus lateralis. Conclusion: Based on these results, it appears that the cross education of strength from unilateral resistance training is modality-specific. Furthermore, the NME of both the vastus lateralis and rectus femoris in both legs appear to improve following unilateral resistance training. However, in the nondominant leg, the improvement in NME appears to be due solely to the increase in maximal EMG, whereas the improved NME in the dominant leg is due to both an increase in maximal EMG and a decrease in submaximal EMG.

Introdução: A avaliação funcional é determinante para a prática da fisioterapia. O uso do teste de elevação do membro (TEMI) na posição supinada, de forma ativa e passiva, permite avaliar a funcionalidade da musculaturaposterior da coxa. Objetivo: Comparar o TEMI ativo e passivo, e de que forma este se correlacionaria com a performance neuromuscular. Metodologia: Análise cinemática do TEMI ativo e passivo, com captura de análise do movimento 3D através do Qualisys Oqus Camera Series (Qualisys), e avaliação da força da musculatura do joelho através do Dinamómetro Isocinético Byodex System 4 Pro™ (Byodex). Resultados: Na avaliação da comparação do TEMI ativo com o TEMI passivo, só se obteve uma diferença estatisticamente significativa (p=0,01), na amplitude máxima de teste, entre a abdução/adução realizada de forma ativa e passiva do membro inferior esquerdo.. Na avaliação da força isocinética, nenhum dos parâmetros avaliados teve uma diferença estatisticamente significativa não existindo qualquer correlação com o TEMI ativo e passivo. Conclusão: Não existem diferenças significativas entre o TEMI ativo e passivo, e os valores deste, não parecem influenciar a performance neuromuscular.
Introduction: Functional assessment is essential for physical therapy practice. The use of the lower limb elevation test (TEMI) in the supinated position, in an active and passive way, allows to evaluate the functionality of the posterior muscles of the thigh. Objective: To compare active and passive TEMI, and how this would correlate with neuromuscular performance. Methodology: Kinematic analysis of active and passive TEMI, with capture of 3D movement analysis through the Qualisys Oqus Camera Series (Qualisys), and evaluation of knee muscle strength through the Byodex System 4 Pro Is Isokinetic Dynamometer (Byodex). Results: In the evaluation of the comparison of the active TEMI with the passive TEMI, only a statistically significant difference (P = 0.01) was found in the maximal test amplitude between abduction/adduction of the left lower limb performed actively and passively. In the evaluation of isokinetic strength, none of the parameters evaluated had a statistically significant difference and there was no correlation with active and passive TEMI. Conclusion: There are no significant differences between active and passive TEMI, and their values do not seem to influence neuromuscular performance.

Streszczenie:
Carnosine (β-alanyl-L-histidine), a histidine containing dipeptide, is one of the most abundant small-molecular compounds in human skeletal muscle. Supplementation with the rate limiting amino acid, β-alanine, has resulted in significant improvements to high-intensity exercise performance. The role of carnosine as an intracellular pH buffer is undisputable, yet other physiological roles have been proposed, including the potential influence of increased carnosine content on regulation of skeletal muscle calcium (Ca2+) kinetics. The movement of Ca2+ is vital during both skeletal muscle contraction and relaxation phases. The overall aim of this thesis was to investigate the effect of β-alanine supplementation on voluntary and electrically evoked contractile properties of in-vivo human skeletal muscle. To examine this research question, there were several aims of this thesis, initially to examine the effect of β-alanine supplementation on intrinsic in-vivo isometric knee extensor force production and skeletal muscle contractility in both fresh and fatigued human skeletal muscle in young (Studies 1 and 2; Chapters 4 and 5) and older (Study 3; Chapter 6) adults. The distribution of the carnosine molecule across subcellular fractions within rat skeletal muscle tissue was explored, as well as the impact of increased carnosine availability on ATPase activity, a measure associated with skeletal muscle relaxation, estimated by Pi generation. In young adults, 28-days of β-alanine supplementation did not significantly influence voluntary and evoked force responses, or the force-frequency relationship, the in-vivo analogue of the force-Ca2+ relationship, in either fresh (Studies 1 and 2; Chapters 4 and 5) or fatigued (Study 2; Chapter 5) skeletal muscle. Furthermore, older adults experiencing pre-existing declines in skeletal muscle function due to ageing, demonstrated no beneficial effect of 28-days β-alanine supplementation on voluntary or electrically evoked skeletal muscle contractions (Study 3; Chapter 6). In young adults, there was, however, a significant decline in skeletal muscle half-relaxation time (HRT) during electrically evoked octet contractions, resting and potentiated twitches (Studies 1 and 2; Chapters 4 and 5). Two possible steps influence skeletal muscle relaxation speed include the Ca2+ removal from the myoplasm and Ca2+ dissociation from troponin followed by cross-bridge detachment. Based on the in-vivo research, it was proposed that there was a direct or indirect mechanism associated with activity of the sarcoplasmic/endoplasmic reticulum Ca2+ ATPase (SERCA) pump, the proposed rate-limiting step of muscle relaxation. In-vitro analysis of ATPase activity demonstrated that SERCA activity was unaffected by increased carnosine concentrations, although there was a significant increase in overall ATPase activity (Study 4; Chapter 7). The results in this thesis showed that β-alanine supplementation was effective in improving skeletal muscle HRT in young adults, although not in healthy older adults. The exact mechanism associated with the in-vivo decline in skeletal muscle HRT remains unclear, yet raising the availability of carnosine in-vitro, does increase overall ATPase activity, although not Ca2+-dependent or SERCA activity.

Streszczenie:
Assessments of skeletal muscle functional capacity or bilateral muscular asymmetry often necessitate maximal contractile effort, which exacerbates muscle fatigue or injury. Tensiomyography (TMG) has been investigated in laboratory settings, as a means to assess muscle contractile function following fatigue; however observations have not been contextualised by concurrent physiological measures. TMG has more sparingly been applied in the field, with elite athletes. The aim of this thesis was to examine acute alterations and underlying variations in muscle contractile mechanics, through the application of TMG, contextualised with established physiological measures; and to apply TMG within high performance sports programmes. TMG successfully detected fatigue, evident from reduced strength, by displaying impaired muscle displacement, accompanied by elevated resting muscle tension. Greater asymmetry was detected in individuals with asymmetric strength; however, symmetry was masked during more complex tasks. Increased day-to-day variability was detected among highly trained athletes compared to recreationally active individuals. Acute training adaptations were detected, in contractile mechanics, in individual muscles. TMG could be useful in establishing fatigue status of skeletal muscle without exacerbating the functional decrements of the muscle, whilst also providing useful screening information for detecting asymmetry which may not be apparent during functional actions.

A dose response relationship between carbohydrate (CHO) ingestion and exercise performance has not been consistently reported. Additionally the underlying metabolic and neuromuscular explanations for an improvement in performance with increasing doses of CHO have not been fully explained. In Chapter 2 of this thesis 20 male cyclists completed 2 h of submaximal exercise followed by a time trial task (531 ± 48KJ). Three CHO electrolyte beverages, plus a control (water), were administered during a 2 h ride providing 0, 20, 39 or 64 g CHO·h-1 at a fluid intake rate of 1 L·h-1. Performance was assessed by time to complete the time trial task, mean power output sustained, and pacing strategy used. Mean task completion time (min:sec ± SD) for 39 g·h-1 (34:19.5 ± 03:07.1, p=0.006) and 64 g·h-1 (34:11.3 ± 03:08.5 p=0.004) of CHO were significantly faster than control (37:01.9 ± 05:35.0). The mean percentage improvement from control was -6.1% (95% CI: -11.3 to -1.0) and -6.5% (95% CI: -11.7 to -1.4) in the 39 and 64 g·h-1 trials respectively. The 20 g·h-1 (35:17.6 ± 04:16.3) treatment did not reach statistical significance compared to control (p = 0.126) despite a mean improvement of -3.7% (95% CI -8.8 to 1.5%). These data demonstrate that consuming CHO at a rate between 39 to 64 g·h-1 is likely to be optimal for most individuals looking to utilise a single source CHO as an ergogenic aid during endurance performances lasting less than 3 hrs. Attempts have been made to try and understand the acute metabolic regulation that occurs when ingesting increasing amounts of CHO. However, no one study has fully investigated the metabolic mechanisms underlying graded increments of CHO ingestion. In Chapter 3 we aimed to utilise stable isotopes and blood metabolite profiles to examine the integrated physiological responses to CHO ingestion when ingested at rates throughout the range where performance gains appear greatest. Twenty well-trained male cyclists completed 2 h constant load ride (95% lactate threshold, 185 ± 25W) where one of three CHO beverages, or a control (water), were administered every 15 min, providing participants with 0, 20, 39 or 64 g CHO·h-1 at a fixed fluid intake rate of 1L·h-1. Dual glucose tracer techniques (6,6,2H2 glucose and U13C labelled glucose) were used to determine glucose kinetics and exogenous carbohydrate oxidation (EXO) during exercise. Endogenous CHO contribution was suppressed in the second hour of exercise when consuming 39 and 64 g·h-1 in comparison to 0 g·h-1 (-7.3%, 95%CI: -13.1 to -1.6 and -11.2%, 95%CI: -16.9 to -5.5 respectively). Additionally, consuming 64 g·h-1 suppressed the endogenous CHO contribution by -7.2% (95%CI: -1.5 to -13.0) compared to the 20 g·h-1 treatment. Exogenous CHO oxidation rate increased by 0.13 g·min-1 (95%CI: 0.10 to 0.15) and 0.29 g·min-1 (95%CI: 0.27 to 0.31) when consuming 39 and 64 g·h-1 in comparison to 20 g·h-1 of CHO. Peak exogenous CHO oxidation rates were 0.34 (0.06), 0.54 (0.09) and 0.78 (0.19) g·min-1 for 20, 39 and 64 g·h-1 respectively. Plasma NEFA concentration was 0.10 (95%CI: 0.07 to 0.13), 0.12 (95%CI: 0.10 to 0.16) and 0.16 (95%CI: 0.13 to 0.19) mmol.L-1 higher when consuming 0 g·h-1 in comparison to 20, 39 and 64 g·h-1 respectively. Both 39 and 64 g·h-1 were effective at sparing endogenous CHO stores of which it is estimated that most of this is liver glycogen sparing, but the measured response was highly variable between individuals. Consuming 39 g·h-1 of CHO appears to be the minimum ingestion rate required to have a significant metabolic effect that results in an increase in performance. Recent research has indicated a key role of endogenous CHO sensing and oral glucose sensing in maintaining central drive and peripheral function during endurance exercise tasks. Consuming 39 and 64 g·h-1 of CHO elicits the greatest improvements in performance and also demonstrate a similar metabolic response. The improvement in subsequent time trial performance when consuming 39 and 64 g·h-1 coincided with significant alterations in whole body substrate usage that lead to endogenous CHO sparing at the same ingestion rates. In Chapter 4 we aimed to utilise gold standard neuromuscular function assessment techniques, alongside novel measures, to investigate the effect of consuming different rates of CHO on neuromuscular function during and following prolonged cycling exercise. In a double-blind, randomised cross-over design, well-trained male cyclists (n=20, mean±SD, age 34 ± 10 y, mass 75.8 ± 9 kg, peak power output 394 ± 36 W, V̇O2max 62 ± 9 ml·kg-1·min-1) completed 2 familiarisation trials then 4 experimental trials. Trials involved a 2 h submaximal ride followed by a high intensity time trial task lasting approx. 35 min with each of 0, 20, 39 and 64 g·h-1 CHO ingestion rates during submaximal exercise. Each trial involved pre and post exercise assessments (MVC, Mwave twitch potentiation and force, motor unit recruitment and firing rate assessment using high density EMG) and during exercise (gross EMG amplitude). MVC peak torque values were reduced post exercise by -20.4 nM (95%CI: -26.5 to -14.4) in comparison to pre value on all trials with no differences between trials. The firing rates of early recruited motor units significantly increased by 1.55 pps (95%CI: 0.51 to 2.59) following exercise in comparison to pre-exercise rates. Gross EMG during the 2 h cycling bout revealed a main effect of treatment (p<0.01) but post hoc comparisons provided no clarity and likely reflect methodological issues. Consuming CHO at ingestion rates between 20 and 64 g·h-1 had little to no impact on the neuromuscular function of well-trained cyclists when comparing pre and post fatiguing exercise values. Despite differences in time trial completion time between trials, following exercise to fatigue in an endurance task, no post exercise differences were detected.

Streszczenie:
In spite of an accumulating volume of information about injury to the musculoskeletal system in recent years, little scrutiny has been focused on the cause and prevention of injury. The large number of injuries to the knee joint and the anterior cruciate ligament ACL ligament in particular, is an alarming sign of the seriousnesso f this problem facing recreational and athletic people around the world. The large number of injuries appears to arise from an unfavourable interaction between `static' connective tissue-related and 'dynamic' muscle-related stabilisers of the joint system (Gleeson et al., 1998; Myers and Lephart, 2000). The functional stability is mediated ultimately by the neuromuscular system (Myers and Lephart, 2000) and it is important therefore to understand the function of the neuromuscular system as fully as possible in order to affect the aetiology and likelihood of injury favourably. The neuromuscular system includes biological 'machinery' offering capability for neuromuscular control (proprioception) and neuromuscular performance (motor actions). The neuromuscular control was quantified by newly-developed and laboratory-based assessmentsin volving the dynamic muscular reproduction of a `blind' target force and the error associated with such efforts may provide greater efficacy of measurement compared to those tests used in contemporary practice which may not indicate an individual's true functional capability to resist injury threats, in particular, to assessth e muscular dynamic intensity associatedw ith sporting endeavours which may functional capability to resist injury threats may be compromised. This thesis is presented as a series of three studies. The aim of this study was to examine between-day reproducibility and single measurement reliability of objective and self-perceived indices of force error in the knee flexors and extensors in men. Results showed that the reproducibility and single-measuremenrt eliability of objective (CE%, VE %) and self-perceived performance (SPCE% and SPVE %) during between-daya ssessmentso f neuromuscularc ontrol NCA1, NCA2 and NCA3 offered compromised precision and efficacy. These indices of performance should be deployed cautiously within both case-study and inter-individual comparisons and must rely on multiple-trial protocols to achieve acceptable levels of measurement precision in such circumstances. The aim of the second study was to examine the effects of serial bouts of acute fatiguing exercise on objective and self-perceived indices of neuromuscular control and performance of the knee flexors in men. In summary, results showed that despite substantial fatigue-related strength and muscle activation impairments, neuromuscular control as measured objectively by NCAI, NCA3 or RJA was not influenced significantly by the fatigue task intervention and that capability in this aspect of neuromuscular control was preserved in response to this type of exercise stress. Furthermore, constant error associated with self-perceived performance was similarly not influenced significantly by the fatigue task intervention. It is plausible that in ordert o provideo ptimump rotectiono f synovialj oints, neuromusculacro ntrol of the kneef lexorsm ay be preservedp referentiallyt o neuromusculapre rformance whenc hallengedb y fatigue-relatede xercises tresses. The third study assessedc oncomitant effects of an episodeo f muscle damage interspersed amongst serial bouts of fatigue on objective and self-perceived indices of neuromuscular control and performance of the knee flexors. This type of exercise perturbation reflects that associated with acute, transient and metabolically-focused effects (fatigue) and that during a more prolonged, mechanical type of disruption to the muscle (EIMD). It was likely to mimic some of the patterns of exercise inherent in sports and training practice and may serve to disrupt dynamic stabilization around the knee joint. Results showed that despite substantial EIMD and fatigue-related strength impairments (the former confirmed in this experiment by means of indirect physiological descriptive variables including a reduced range of movement and an increase in pain upon active movement of the affected limb), neuromuscular control as measured by objective and self-perceived indices of constant and variable error in assessment protocols NCA 2, NCA3 and DNCA was not influenced significantly by the EIMD and fatigue task intervention. It was notable that capability in this aspect of neuromuscular control was preserved in response to this type of exercise perturbation in the three different modes of objective assessments of neuromuscular control used in this study.

The goal of this work is to present methodology to first evaluate the performance of an in vivo spine system and then to synthesize optimal neuromuscular control for rehabilitation interventions. This is achieved 1) by determining control system parameters such as static feedback gains and delays from experimental data, 2) by synthesizing the optimal feedback gains to attenuate the effect of disturbances to the system using modern control theory, and 3) by evaluating the robustness of the optimized closed-loop system. We also apply these methods to a postural control task, with two different control strategies, and evaluate the robustness of the spine system with respect to longer latencies found in the low back pain population. This framework could be used for rehabilitation design as discussed at the end of the paper.

Abstract Understanding the mechanisms behind human balance has been a subject of interest as various postural instabilities have been linked to neuromuscular diseases (Parkinson’s, multiple sclerosis, and concussion). This paper presents a classification method for an individual’s postural stability and estimation of their neuromuscular feedback control parameters. The method uses a generated topological mapping between a subjects experimental data and a data set consisting of time series realizations generated using an inverted pendulum mathematical model of upright balance. The performance of the method is quantified using a time series realizations with known stability and neuromuscular control parameters. The method was found to have an overall sensitivity of 85.1% and a specificity of 91.9%. Furthermore, the method was most accurate when identifying limit cycle oscillations with a sensitivity of 91.1% and a specificity of 97.6%. Such a method has the capability of classifying an individual’s stability and revealing possible neuromuscular impairment related to balance control, ultimately providing useful information to clinicians for diagnostic and rehabilitation purposes.

The purpose of this research is to enhance the methods used in biomechanical rehabilitation by combining virtual reality, motion capture and biofeedback instrumentation. During training the subject is wearing a head-mounted helmet, in which virtual tasks (i.e. motions) are displayed to him. During training, the patient is asked to follow target motions which are displayed to him and match his own movement to them. During training the patient kinematics and electromyograms (E.M.G.) signals are being tracked by Vicon Motion tracking system. We use an intelligent learning system to learn, on-line patient performance. For training, we use kinematics and electromyogram data provided by the Vicon motion system. Once trained, the system changes and adapts the tasked displayed to the subject for better patient-specific neuromuscular rehabilitation. Moreover, the system creates a more entertaining environment also resulting in a more efficient physiotherapy in adults and especially in pediatric. Besides physiotherapy, this system can be used in other applications, such as performance enhancement in sports training and as an educational tool in any application requiring precise movement and coordination.

Streszczenie:
Four Army pilots participated in a simulation experiment to examine the influence of stick location and sensitivity (gain) on pilot neuromuscular (NM) response, performance, and workload. The experiment employed an active inceptor that was positioned between the pilot's legs or, adjacent to the pilot's right side with an armrest. Two stick sensitivities that varied by a factor of four were evaluated using a single-axis compensatory tracking task in the longitudinal and the lateral axes. The experiment results identified two prominent NM modes at roughly 10 and 25 rad/s; stabilizing the elbow implicated the 10 rad/s mode with forearm motion, and wrist/finger motion with the mode at 25 rad/s. With the longitudinal task using the low stick gain, workload ratings were significantly higher for the side stick than the center stick. A preliminary analysis indicated that the greater resisting force between the forearm and non-compliant armrest (side stick configuration) relative to the resisting force between the forearm and leg (center stick configuration) may be a key factor in the higher workload. This suggests that a side stick's gain in the longitudinal axis should be a function of task such that control displacements are generally small. Overall workload during manual tasks would benefit if this approach were applied to all control axes. A second study was conducted to investigate the significant effect of stick gain on crossover frequency that was observed in the first experiment. These results showed that the ratio of stick rate to stick amplitude is directly proportional to crossover frequency, and that a tradeoff between rate and amplitude reflected by changing crossover is similar to the phenomenon described by Fitts Law, where manual movement time is related to the distance travelled. The implications for design are that stick travel can affect performance much more than stick force provided the stick dynamics do not adversely interact with the NM system. It is recommended that the feel system mode should lie between the forearm and wrist/finger NM modes, and that stick sensitivity selection should be based on mission and operating environment.

A realistic driver model can support the development of new steering technologies by reducing the time-consuming trial and error process of designing products. A neuromuscular driver model, by offering physiologically realistic steering maneuvers can provide insights into the task performance and energy consumption of the driver, including fatigue and muscle co-contraction. Here, two muscles are used in a simplified neuromuscular driver model. To study the effect of driver’s characteristics such as age, gender and physical ability on steering, the muscle parameters are adjusted to represent a particular population. Then, this modified driver model is used to to tune the Electric Power Steering (EPS) assist curves for that particular population.
