▼ Blood flow restriction (BFR) in combination with exercise has been shown to result in favorable effects on skeletal muscle mass and function. However, most protocols have used an arbitrary pressure or they have based the restrictive pressure off of brachial systolic blood pressure, which is not a valid predictor of arterial occlusion in the lower body. This study sought to determine the most effective low load protocol with and without different degrees of BFR (determined based on limb circumference) and determine how it compares to higher load (HL) resistance exercise. PURPOSE: The purpose of this study was to compare acute skeletal muscle changes following differing resistance exercise protocols. In addition, the perceptual response to each of those protocols was investigated. METHODS: Participants completed five separate visits. On the first visit, participants: 1) completed paperwork; 2) were screened further for eligibility (Blood Pressure; BMI); 3) completed one repetition maximum testing on the knee extension; and 4) were familiarized with the BFR stimulus. Following the first visit, participants were randomly assigned to either group A, group B, or group C. Within each group, the participants were further randomized into which condition they completed first, second, third, and fourth. The conditions included three exercise conditions and one control condition. During each visit, participants had their muscle thickness and circumferences measured on their non-dominant leg. Following this, their dominant leg was prepped for electromyography (EMG). Participants completed a maximal voluntary contraction (MVC) with their dominant leg, rested for five minutes, and then completed the protocol designated for that day. The protocols within Group A included HL exercise at 70% 1RM, exercise at 20% 1RM with 40% estimated arterial occlusion (20%/40 BFR), exercise at 30% 1RM with 40% estimated arterial occlusion (30%/40 BFR), and a non-exercise control (CON). The protocols within Group B included exercise to failure at 30% 1RM, exercise at 20% 1RM with 50% estimated arterial occlusion (20%/50 BFR), exercise at 30% 1RM with 50% estimated arterial occlusion (30%/50 BFR), and a non-exercise CON. The protocols within Group C included exercise to failure at 20% 1RM, exercise at 20% 1RM with 60% estimated arterial occlusion (20%/60 BFR), exercise at 30% 1RM with 60% estimated arterial occlusion (30%/60 BFR), and a non-exercise CON. The 70% 1RM protocol was completed with one minute rest between sets. All other protocols were separated by 30s rest. In addition, after every set of exercise, RPE and discomfort were quantified. During the CON conditions, participants sat in the knee extension device for ~5.5 minutes to mimic the estimated time to complete a normal exercise bout. A comparison across groups was plotted and visually examined to descriptively compare conditions when effect sizes were unable to be calculated (i.e. EMG, perceptual responses).

▼ Sedentary behavior has been found to have independent and negative associations with several cardiometabolic risk factors while interrupting prolonged sedentary time may ameliorate these associations. College classrooms are a traditionally sedentary microenvironment and understudied setting for sedentary interventions. Introducing sit-stand desks into college classrooms may be an effective and sustainable approach to reduce classroom sedentary time of college students. The objective of this study was to test the efficacy of replacing seated desks with sit-stand desks in a college classroom on student’s classroom standing time and sit-stand transitions, as well as health-related and academic behaviors. We recruited 304 undergraduate college students taking one of 14 classes being taught in one of two small classrooms (25 seats per class) to participate. Using a cross-over design, each student’s classroom sitting and standing time were measured by self-report and objectively (direct observation via video camera surveillance) after having access to only seated desks or only sit-stand desks for six continuous weeks. A process evaluation survey was administered at the end of the study to explore student’s and instructor’s perceptions of the intervention and its impact on student engagement. The results suggest that students stood about 9.1% of class time on average when given access to sit-stand desks and about 1.95% of class time when using traditional seated desks, as measured by objective video surveillance data. There was no significant change in sit-stand transitions between sit-stand desks and seated desks. Students reported that a number of academic and health outcomes were favorably impacted as a result of using the sit-stand desks. Social acceptability appeared to be the biggest barrier to use of the sit-stand desks. Overall, students reported a desire to use sit-stand desks again in future classes. Students stood significantly more when provided access to sit-stand desks compared to seated desks. Sit-stand transitions were not significantly increased when sit-stand desks were implemented. Significantly more students reported improvements in academic and health related outcomes than students who reported declines in these areas as a result of using sit-stand desks. A majority of students reported they would use sit-stand desk again in the future and be supportive of adding sit-stand desks to other classrooms on campus. Sit-stand desks are a feasible environmental change in a college classroom to reduce student sedentary time. Advisors/Committee Members: Carr, Lucas J. (supervisor).

▼ In humans, it is thought that both central commands and peripheral feedback from sensory receptors contribute to the control of locomotion. An important problem that exists in human locomotion research is the interactions and balance between the individual contributions of the central (CNS) and peripheral (PNS) nervous systems to the control of muscles during movement are not fully understood. Applying external perturbations such as stretches, tendon taps, and electrical stimulation to the neuromuscular system during walking can help us learn more about how the response to afferent information is modulated during locomotion. To date, most of the research looking at modulation of the response during walking has investigated the soleus and quadriceps muscles. Very little research has focused on the hamstring muscles, which are important during walking, particularly during late swing. One reason for this is that it is difficult to detect H-reflexes in hamstrings following electrical stimulation of the sciatic nerve. The purpose of this study was to demonstrate a new sciatic nerve stimulation technique and use it to study the modulation of the response to afferent feedback during walking. This study consisted of two parts: 1) Establish the presence of an afferent mediated response (H-reflex) during prone lying in hamstrings muscles, and 2) Investigate the modulation of this afferent feedback during walking. Subjects underwent single and double pulse stimulations to the sciatic nerve during prone lying, followed by electrical stimulation at 12 different phases of the gait cycle. For each phase, stimulus response curves were created in which maximal direct (M-wave) and afferent mediated responses (H-reflex) could be determined. Maximal H-reflex (Hmax) was normalized to maximal M-wave (Mmax) to create an H:M ratio that was used to compare modulation of the responses between phases and subjects. Electrical stimulation of the sciatic nerve elicited detectable H-reflexes in biceps femoris during prone lying and walking. The modulation of the response to afferent feedback is not the same for all phases of the gait cycle, particularly in late swing when it has a higher amplitude than the rest of the gait cycle. This modulation was not simply related to background EMG as would be expected during isometric contractions. Thus, there must be both central and peripheral influences on the response. Understanding the control of human locomotion is important for developing rehabilitation programs for patients with lesions of the central nervous system such as stroke or spinal cord injury.

▼ Purpose: To examine the maturity-related differences in the adaptations to systemic and localized fatigue thresholds (FTs) in response to sprint interval training (SIT) amongst adolescent male athletes. Methods: Twenty-seven adolescent male athletes, 11-17 years of age, completed pre-testing, six weeks of SIT, and post-testing. Participants were grouped according to their number of years from peak height velocity (PHV), an estimation of somatic maturity status, into PRE ( < -1.5yr), PERI (between -1.5 to +1.5yr) and POST ( > +1.5yr) PHV groups. Each testing session consisted of a ramp exercise protocol on a cycle ergometer. During the protocol, three systemic FTs, gas exchange threshold, ventilatory threshold, and respiratory compensation point were calculated from gas exchange and ventilatory parameters. Also, three localized FTs, neuromuscular fatigue threshold (NFT), deoxyhemoglobin breakpoint (HHbBP), and oxygenation deflection point (OxDP) were calculated from electromyography (NFT) and near-infrared spectroscopy signals (HHbBP and OxDP) from the vastus lateralis of both legs. Data were plotted versus oxygen consumption and 30-second moving averages were calculated. All FTs were determined using the maximal distance method. Localized FTs were averaged between the two legs. The six weeks of SIT consisted of repeated 20-second "all-out" sprints on a cycle ergometer against a load equivalent to 7.5% of body mass with 4-minute rest periods. Maturity-related differences to the adaptations to SIT were assessed with mixed-factorial ANOVA and magnitude-based inferences. Results: During training, POST and PERI completed significantly greater relative work (p=0.003 and p=0.002, respectfully) and peak power (p=0.025 and p=0.023, respectfully) per session than PRE. Furthermore, POST achieved significantly greater peak rotations per minute than PRE (p=0.001) and PERI (p=0.042) during the first training session. No significant group-time interactions existed for absolute V?O2max (p=0.386), relative VO2max (p=0.341) or maximum workload (p=0.593). However, there was a significant group-time interaction (p=0.030) for FTs, with POST having significantly greater changes than PRE (p=0.026) and PERI (p=0.023), and was the only group to experience a significant improvement in FTs from training (p < 0.001). In addition, magnitude based inferences revealed that POST had Likely improvements in all measures of maximal aerobic performance, while PERI only had Likely improvements in maximum workload and PRE experienced Trivial changes. Furthermore, all measured FTs experienced Likely or Very Likely improvements amongst POST; however, PRE and PERI only had improvements in NFT and HHbBP. Conclusion: SIT improved maximal aerobic performance and FTs in POST, but had limited affects in PRE and PERI. The maturity-related differences in the adaptations to SIT may be due to the differences in performance during the training program or underlying physiological changes that occur with maturation.

▼ The primary objective of this study was to evaluate the synergistic effects of repeated sprint training in hypoxia (RSH) and beta-alanine supplementation on performance in recreationally active men. Participants were randomly assigned to one of the following groups: hypoxia + beta-alanine (HB, n = 10), hypoxia + placebo (HP, n = 9), normoxia + beta-alanine (NB, n = 11) and normoxia + placebo (NP, n = 8). All participants completed a total of 8 training sessions (each consisting of 3 sets of 5 × 10-s sprints at a resistance of 7.5% of body mass, with 20-s rest intervals between sprints) over 4 weeks on a cycle ergometer either in hypoxia (Oxygen fraction: FiO2 = 14.2%) or normoxia (FiO2 = 20.9%). Participants were instructed to consume a daily dosage of 6.4g (two 800 mg tablets ingested 4 times per day at 3-4 hour intervals) of either beta-alanine or placebo. Changes in performance in a graded exercise test (GXT), repeated sprint test (RST) and 3-min all-out test (3MT) were examined before and after 28-days of training and supplementation. Aerobic performance was measured by maximal oxygen consumption (VO2max), peak power output (PPO). Exercise intolerance was assessed from critical power (CP), oxygen consumption (VO2RCP) and power output (PRCP) at respiratory compensation point. Exercise capacity was measured by total work (TW) during 3MT. Anaerobic capacity was evaluated via anaerobic working capacity (AWC), heart rate response to RST (RST_HR60) and lactate responses to RST (RST_La) and 3MT (3MT_La). Repeated sprint performance was estimated through average power output of the last sprint (RST_AP5) and all sprints (RST_AP). No between-group differences were observed for training volume or supplementation compliance. Anthropometric and hematological measures remain unchanged before and after intervention in all groups. A main effect of altitude was shown for VO2RCP, PRCP, RST_AP5, RST_HR60, and TW, with post-intervention values in the hypoxia groups significantly (p < 0.05) higher (lower for RST_HR60) than the normoxia groups. A main effect of beta-alanine was detected in AWC, with post-intervention values in the beta-alanine groups being significantly (p < 0.05) higher than the placebo groups. Results of this investigation demonstrated that RSH and beta-alanine benefit performance from different perspectives. RSH improved aerobic performance, exercise tolerance, cardiovascular recovery and exercise capacity, while beta-alanine supplementation maintained anaerobic working capacity in recreationally-trained men during the four-week repeated sprint training intervention.

▼ Previous research has investigated the use of music as an ergogenic aid for exercise performance; however, the effect of music on exercise may differ between individuals of varying levels of mental toughness (MT). Purpose: The purpose of this study is to examine the moderating effect of MT on the effect of listening to music during exercise. Methods: The current study used a counter-balanced design, utilizing a mixed-methods approach. Thirty-one recreationally-active individuals (22.13 ± 2.11 yrs, 1.73 ± .10 m, 75.68 ± 14.67 kg, 42.89 ± 5.31 mL·kg·min-1; 65.5% males) were recruited for this study. Participants completed an initial visit to complete a MT questionnaire and create a personalized music playlist of at least 15 songs. Participants completed two familiarization trials and a VO2max test on the treadmill, all on separate days. The experimental trials consisted of two separate conditions: 1) no music (NM); and 2) self-selected music (SSM). For each experimental trial, participants performed a time-to-exhaustion (TTE) run at 80% of their VO2max, separated by at least 48 hours, followed by a post-study interview. Pearson product-moment correlations were used to investigate relationships between performance variables and MT. Moderated regression analysis was used to determine a potential order effect, as well as a potential moderating effect of MT on change in performance between NM and SSM groups. Linear regression analysis was used to determine a potential relationship between MT and change in performance between NM and SSM groups. An alpha level of p ≤ 0.05 was used to determine statistical significance. All qualitative data from post-study interviews was transcribed, coded, and categorized into primary themes. All statistical analyses was conducted via the Statistical Package for Social Science (SPSS) software for Windows version 21 (SPSS Inc., Chicago, IL). Results: Averages were calculated for MT (156.39 ± 9.38), TTE SSM (14.18 ± 4.79 minutes), and TTENM (12.23 ± 5.24 minutes). Correlations were found between VO2max and TTESSM, TTENM, and MT (r = 0.390, p = 0.030; r = 0.519, p = 0.003; r = 0.404, p = 0.024; respectively). Moderated regression analysis revealed a non-significant interaction between MT, music, and order, indicating no order effect (β = -0.416, p = 0.735). Independent samples t-tests revealed no significant difference in MT, performance, or VO2maz between groups of participants who received music first or music second, indicating no effect of order (F = 0.388; p = 0.538; F = 0.537; p = 0.470; F = 0.070; p = 0.794; respectively. Moderated regression analysis, via linear regression, determined no significant moderating effect of MT on the change in performance between trials (ΔTTE) (F (3, 58) = 0.958, r = 0.217, p = 0.498). Linear regression, however, revealed a significant main effect of MT, indicating an inverse relationship between MT and ΔTTE (F (1, 29) = 4.417, r = -0.634, p = 0.044). Discussion: The results from the current study indicate that greater levels of MT were associated with less… Advisors/Committee Members: Garcia, Jeanette.

▼ Traditionally, post-exercise muscular alterations have been examined using invasive techniques that lack the ability to single out individual muscle groups. Sonomyography, tensiomyography, and electrical impedance myography allow for noninvasive skeletal muscle assessment. This project aimed to examine changes in muscle contractility and composition that occur in the early stages of recovery following unaccustomed exercise. METHODS: Twenty-one untrained adults (21.9 ± 1.9 y) performed exercise – 10 × 10 maximal eccentric knee extensions – with their nondominant leg. For each repetition, participants moved through 90° range of motion at 90°•s-1 with a passive return to the start position. Each set was separated by 60 seconds of rest. Sonomyography, tensiomyography, electrical impedance myography, and maximal isometric contractions of the knee extensors (RF & VL) of both legs were performed before (BL), immediately after (IP), and 24 hours post-exercise (24H). RESULTS: Peak torque and rate of torque development were unaltered in response to the eccentric protocol. Significant limb × time interactions were noted for reactance, phase angle, and delay time of the exercised VL, and echo intensity of the exercised RF. Compared to the dominant leg, the nondominant leg displayed significantly greater changes (p < 0.05) in VL delay time and RF echo intensity at IP. Following exercise, bilateral alterations were identified for reactance, phase angle, maximal displacement, delay time, contraction velocity, cross-sectional area, and thickness of the RF, as well as resistance, echo intensity, cross-sectional area, and thickness of the VL. No between-sex differences were noted in response to exercise. CONCLUSIONS: In the absence of performance decrements, sonomyography, tensiomyography, and electrical impedance myography successfully detected acute changes in skeletal muscle composition and function following an acute bout of eccentric exercise in untrained men and women. While the exercised leg exhibited specific responses in delay time and echo intensity, bilateral changes are theorized to have occurred due to contralateral stabilization of the non-exercised leg. The current results suggest that different muscle actions (i.e., eccentric and isometric) promote similar consequences to muscle strength, size, echogenicity, contractility, and bioelectrical properties.

▼ INTRODUCTION: Ultrasound assessment of the lower body typically encompasses 10-15 minutes of supine rest prior to examination because of the potential influence of gravitational fluid shifts on tissue size and composition. However, examination of the vastus lateralis (VL) muscle requires individuals to lay in the lateral recumbent position, and this change in position may influence muscle morphological characteristics and their ability to predict muscle function. PURPOSE: The purpose of this investigation was to examine the effect of rest position on ultrasound-derived morphological characteristics of the VL and to determine whether or not rest position affects the relationships between muscle morphological characteristics of the VL and lower-body force and power production. METHODS: Thirty-one resistance-trained males (age: 23.0 ± 2.1 years; height: 1.79 ± 0.08 m; body mass: 87.4 ± 11.7 kg) participated in this investigation. Muscle morphological characteristics, including cross-sectional area (CSA), muscle thickness (MT), pennation angle (PA), echo intensity (UnCorEI), subcutaneous adipose tissue thickness (SFT), and EI corrected for SFT (CorEI) of the VL were assessed in the dominant limb after 15 minutes of rest in 3 recumbent positions: supine (SUP), dominant lateral recumbent (DLR), non-dominant lateral recumbent (NDLR), as well as after 15 minutes of standing (ST) and immediately after laying down (IP). Following ultrasound assessments, participants completed unilateral performance assessments, including vertical jumps (UVJ), isometric/isokinetic testing, and a 1-repetition maximum (1-RM) leg press. RESULTS: A repeated-measures analysis of variance revealed significantly different (p < 0.05) CSA, MT, PA, UnCorEI, and SFT in ST compared to recumbent positions after 15 minutes of rest (NDLR, DLR, and SUP). Additionally, significant differences were observed between recumbent positions for CSA, CorEI, and UnCorEI; however, no differences were observed for MT, PA, and SFT. Different magnitudes of relationships were observed between muscle morphological characteristics measured after rest in different positions and performance variables. However, muscle morphology after IP generally appears to be the best predictor of performance for most variables, although utilizing the NDLR and DLR positions may provide comparable, or potentially stronger results for variables such as IsokPF. The relationship between muscle morphology and various performance variables in ST were weaker compared to the recumbent positions examined, specifically for IsokPF, 1-RM leg press, and for all UVJ variables, except total work. CONCLUSIONS: Muscle morphology differs depending on the rest position utilized prior to ultrasound analysis. These rest positions also affect the ability for muscle morphology to predict lower-body force production. Future research should consider evaluation of muscle morphology of the VL after IP in the prediction of muscle function; however, NDLR and DLR may also be used. SUP and ST provide significantly weaker… Advisors/Committee Members: Wells, Adam.

▼ INTRODUCTION: Accurate body composition assessment is crucial for determining health consequences due to excess body fat (BF). While several techniques exist there are few that are accurate, non-invasive, fast, and comfortable for subjects. The Three Dimensional (3D) body scanner is a new body composition assessment method that might serve as another option for investigators and practitioners. The purpose of this study was to determine the accuracy of the 3D body scanner at measuring body composition using dual energy x-ray absorptiometry (DXA) and Air displacement plethysmography (Bod Pod) as criterion measures. The 3D body scanner was evaluated on its ability to work with differences in normal versus overweight subjects as determined by BMI. Also, a new prediction equation was created and compared to that of an existing equation used by the 3D body scanner developed by the Department of Defense (DoD). METHODS: Eighty-Five male subjects (21.70 ± 2.28 yr old; 81.00 ± 12.21 kg; 25.37 ± 3.40 kg/m2 ) completed all body composition assessment techniques on the same day. Tests preformed included: DXA, Bod Pod, and 3D body scanning. Subjects did not eat or drink 2 hr previous to testing and did not exercise 4 hr previous to testing. Data was analyzed using SPSS version 17.0. Bland-Altmand plots, Pearson correlations, and a oneway ANOVA comparing means were performed. A prediction equation (3D MU) was created using a stepwise regression based on correlation to DXA. RESULTS: Mean comparison of body composition techniques were as follows: DXA BF 16.30 ± 4.67; Bod Pod 12.17± 7.19; DoD 13.53 ± 6.43; 3D MU 16.49 ± 4.16. 3D MU had a SEE=3.09 over the entire sample compared to DoD SEE=3.67 and Bod Pod SEE=2.45. Although body volumes of Bod Pod and 3D Scanner were highly correlated (r = 0.984; p =0.001), the 3D Scanner underestimated body volume. Improvement in making consistent estimations of head, hand, and feet are necessary for the 3D body scanner to be used for body composition as Advisors/Committee Members: Ball, Stephen D.

▼ Australian football is a dynamic team sport, which requires players to perform a large number of high-intensity efforts, combined with low-intensity activities throughout a match. Due to the complex and unique demands of the sport, players require an adequate training stimulus to develop and enhance the physical qualities required to succeed at the highest level. The ability to develop physically challenging but appropriate training at an individual level to 1) enhance the technical and physical qualities required, and 2) minimise the negative response to training (i.e. injury, illness, etc.) is a crucial task for practitioners involved in the preparation of elite players. The cost of injury in elite sport is substantial, with player availability seen as a key factor in the success or failure of any professional sporting organisation. It is typically suggested that teams with higher injury rates are more likely to be negatively impacted through poor team performance, compared with teams with lower injury rates. If injuries (particularly non-contact, soft-tissue injuries) can be considered ‘largely’ avoidable, then the role of workload becomes a key component in any sporting organisation to manage and minimise the risk of injury. The notion that workload and injury are interrelated is well established, yet the cost of injury remains significant at the professional level of Australian football. The overall aim of this program of research was to use scientific literature to understand the relationship between workload, injury, and performance in elite Australian football players and then improve the understanding of workload management and modelling of workload variables measured using a commercially available microtechnology unit. The program of research in this thesis first produced a comprehensive literature review to identify the current problem (s). The six subsequent chapters of original research built on the literature review to examine, in elite Australian football, (1) a previously suggested fitness-fatigue model on injury risk, (2) the importance of pre-season training on in-season availability, (3) the use of relative speed zones to model workload at an individual level, (4) a newly proposed fitness-fatigue model, (5) the differences between fitness-fatigue models in an applied setting, and finally (6) the application of a training monitoring system on injury rates. A previously-established monitoring tool, the acute:chronic workload ratio, was used to quantify the relationship between workload and injury in a cohort of professional Australian football players. The size of the acute workload in relation to the size of the chronic workload was calculated as an acute:chronic workload ratio. A very high acute:chronic workload ratio (i.e. > 2.0) for total distance was associated with a 5 to 8- fold increase in injury risk during the season. Similarly, players with a high-speed running acute:chronic workload ratio of > 2.0 were 5-11 times more likely to sustain an injury in both the current…

▼ Skeletal muscle fatigue is a multifactorial process that leads to decrements in the force generating capacity of the neuromuscular system. During a maximal unilateral and bilateral contraction, complex interactions occur along the length of the neuromuscular system. These interlimb limb interactions occur with and without the presence of fatigue, however, it is unknown whether illusionary mirror visual feedback moderates the effects. The primary purpose of this study was to examine the influence of unilateral fatigue, with and without illusionary mirror visual feedback, on the maximal force of the fatigued and non-fatigued limb during unilateral and bilateral contraction. A secondary purpose was to examine the bilateral index and whether sex moderated the responses. Thirty healthy right-hand dominant participants (n = 15 males; 15 females) completed this study. After a familiarization session, the participants completed four experimental visits (no-mirror, mirror, non-dominant, and control) in a pseudo-randomized order. The fatigue protocol required the participants to perform nine, 20 second maximal unilateral handgrip contractions. This protocol was performed with (mirror) and without (no-mirror) illusionary mirror visual feedback with the dominant hand. The fatigue protocol was also performed with the non-dominant (non-dominant) hand without mirror visual feedback. Maximal strength and electromyographic (EMG) amplitude of the flexor carpi radialis and extensor carpi radialis were collected for both hands during unilateral and bilateral contractions before and after the fatigue protocol. The relative change (%Δ) in maximal strength and EMG amplitude was compared between visit, contraction, and sex. The bilateral index was also compared between hands and sex. The main findings show that: 1) bilateral force loss was significantly (p < 0.05) greater than unilateral force loss during the no-mirror and non-dominant visit, but not during the mirror visit (p > 0.05), 2) there were no significant (p > 0.05) changes in maximal force for the contralateral, non-fatigued hand during maximal unilateral contractions, yet there was for the bilateral contraction following the non-dominant visit (p < 0.05), 3) there was a significant (p < 0.05) increase in EMG amplitude for the non-fatigued flexor carpi radialis during the mirror visit, 4) there was a significant (p < 0.05) bilateral deficit and it was greater for the dominant hand compared to the non-dominant hand (p < 0.05), and 5) sex did not have a significant influence on any of the comparisons (p > 0.05). Together, these findings present several novel observations related to neuromuscular fatigue and cross-limb interactions.

▼ Sprint performance can be enhanced by interventions for short-term (acute) purposes and/or long-term purposes. Acute neuromuscular responses are usually achieved by using different pre-exercise routines at the end of the warm-up period. Recently, there have been several studies examining the effects of various pre-exercise routines on sprint performance, yet there has not been a research study designed that compared the three most commonly used pre-exercise routines in professional and recreational sports (static stretching, dynamic stretching and foam-rolling). Therefore, this study investigated and compared the results of static stretching, dynamic stretching, self-myofascial release and the control group, in order to provide some general findings in this field of sport performance. The purpose of this study was to examine the acute effects of different pre-exercise routines on 60-meter sprint performance. Moreover, the study investigated whether static stretching impairs sprint performance. Ten students from a Midwestern U.S. University were recruited to participate in this study, with 8 participants successfully finished the study. Each participant underwent all four intervention protocols in a randomized order. A repeated measures ANOVA statistical analysis indicated a significant main effect with post-hoc testing comparing 60-meter sprint results for each pre-exercise protocol did not show statistical significance amongst the selected values: SS time - DS time, SS time - CG time, SMR time - DS time, SMR time - CG time, and DS time - CG time (p=0.061; p=0.259; p=0.356; p=0.111; p=0.265; respectively). However, comparing the results from the SS group and the SMR group showed that the SMR had a significantly greater effect than the SS (p=0.024), The findings of this study indicate that using self-myofascial release is a more beneficial pre-exercise protocol for improving 60-meter sprint performance than either static or dynamic stretching. . Additionally, the results suggest that static stretching does not impair 60-meter sprint performance compared to a control group. Advisors/Committee Members: Brian L. Pritschet.

▼ Purpose: This study was designed to track the changes in body composition of college football players before and after a 14-week competitive season while tracking diet changes. The first hypothesis of this study was that collegiate football players would decrease muscle mass and increase their body fat percentage from before to after the season. The second hypothesis was that caloric intake would be greater after the season than before the season. Methods: Body compositions of 53 NCAA Division I football players from South Dakota State University (20 ± 1 years) were tested pre and post season using a DXA. Body mass, lean mass and fat mass were all evaluated. Subjects completed a 3-day diet record at both testing times, pre and post season. All measures were statistically analyzed for pre-post season differences. The players were looked at as a whole as well as broken down into two different groupings: linemen vs. non-lineman (skill) and upperclassmen (juniors and seniors) vs. lowerclassmen (freshmen, red-shirt freshmen, and sophomores). Results: Significant changes in body mass and lean mass were observed over the course of the season for all participants. Body mass declined significantly 1.2% during the 14 week season. The change in body mass (1.7 ± 3.2 kg) was due to a significant decline (1.7 ± 2.3 kg) in lean mass. Fat mass did not change during the course of the season. The significant loss in lean mass was observed in the arms, legs, and trunk. There were differences at baseline between linemen and skill players. Linemen were heavier, had more lean and fat mass than those classified as skill players. During the football season, both linemen and skill players experienced significant changes in body composition. Linemen lost 1.7 ± 2.8 kg of mass and 1.9 ± 1.7 kg of lean mass. Linemen did not experience any change in body fat. Skill players also experienced a significant decline in mass (0.8 ± 2.8 kg) and lean mass (1.0 ± 1.8 kg). The decline in lean mass was greater (p=0.06) for linemen compared to skill players. Regional changes demonstrate that lean mass is lost similarly in the arms, legs, and trunks for linemen but only the legs for skill players. There was no difference between upper- and lower-classmen in body composition measurements at baseline. However, upper-classmen experienced significantly greater changes in body composition compared to lower-classmen. Upperclassmen experienced a decline in body mass of 2.3 ± 2.7 kg and lean mass declined 1.9 ± 1.6 kg. Fat mass significantly increased in the lower classmen (0.9 ± 1.7 kg) but did not change in the upper-classmen. Upper-classmen experienced significant declines in arms, legs, and trunk lean mass, while lower-classmen experienced significant declines in lean mass in the legs and trunk. The macronutrient composition of the diet was not different from pre-season to post-season. Conclusion: The results of this study indicate the body composition, specifically body mass… Advisors/Committee Members: Matthew Vukovich.

▼ Acute lower body exercise elicits adverse effects on balance performance and subsequent fall risk. However, little information exists for upper body exercise and postural sway. The series of experimental studies presented in this thesis investigated the effects of acute upper and lower body exercise on postural sway in healthy young and older adults and determined whether the acute negative effects of exercise can be removed by an improvement in training status. Chapter 4 examined the effects of maximal and submaximal (absolute and relative exercise intensities) arm crank ergometry (ACE) and cycle ergometry (CE) on postural sway in young healthy adults. Cycling elicited an immediate increase in post exercise postural sway whereas ACE did not. Chapter 5 compared the effects ACE, CE and treadmill walking (TM) on postural sway in healthy older adults. Based on the findings of Study 1, submaximal exercise was performed at the same relative intensity (50 % HRE). In agreement with Chapter 4, CE and TM elicited post exercise balance impairments lasting for ~ 10 min post exercise. ACE performed at the same relative intensity as the lower body did not elicit post exercise balance impairments in older adults. Collectively, these acute studies suggest that lower limb exercise may acutely increase fall and injury risk in the immediate period after exercise cessation. This is important because practitioners and clinicians should acknowledge that the prescription of conventional training modes might potentially elicit transient impairments in neuromuscular function. However, in this context it appears that seated exercise with the arms may not induce a significant enough stimulus to cause sensorimotor disturbance to postural stability and thus may be a safer alternative exercise mode for fall risk populations or individuals who are very sedentary. Chapter 6 examined differences in balance performance, as measured by quantitative posturography and functional balance tests, among different age groups. Measures of postural sway were able to distinguish between younger (< 60 years) and older ( > 60 years) adults whereas functional performance tests suggested that balance impairments were observed earlier ( > 50 years). This study enabled a range of tests to be determined for use with subsequent training interventions. Chapter 7 examined the effects of 6-weeks upper or lower body exercise training on postural sway. Upper and lower body training elicited similar improvements in specific (~ 25 %) and cross transfer (~ 12 %) exercise tolerance. Both modes of training elicited favourable balance adaptations. Specifically, upper body training improved mediolateral aspects of postural sway, while lower body training improved anteroposterior aspects of sway. It was proposed that an improvement in cross transfer exercise capacity after upper body exercise reduced the physiological strain experienced during CE, thus reducing post exercise balance impairments and that an increase in abdominal and trunk strength from upper body exercise training…

Glickman, Ph.D. Angela L. Ridgel, Ph.D. PURPOSE: The purpose of the current investigation was to determine the effects of hypoxia (12.5% O2) and low intensity exercise (50% of hypoxic VO2max) on physiological and cognitive performance in a middle-aged group. METHODS: Eight physically active (35.9 ± 5.7 ml·kg-1·min-1), middle-aged (40.5 ± 2 yr) males volunteered to participate in the present investigation. Prior to experimental testing, participants underwent a graded exercise test (Excalibur 1300Wcycle ergometer) to estimateVO2maxin hypoxia. Following pre-experimental testing participants underwent three 5h trials [hypoxia (H), hypoxia with exercise (H+E) and normoxia with exercise (N+E)] consisting of 2h baseline, 1h cycling, 2h recovery. All testing was conducted in a simulated hypoxia chamber (Colorado Altitude Training, Louisville, CO), and oxygen was maintained at 12.5%. Minute Ventilation (VE), Oxygen Consumption (VO2), Heart Rate (HR), Mean Arterial Pressure (MAP), Arterial Oxygen Saturation (SaO2) and Cerebral Oxygenation (rSO2) were measured prior to entering the chamber and every 30 min. In addition, Mood State (POMS), Acute Mountain Sickness (AMS) and Trail Making Tests (TMT) were measured prior to entering the chamber and measured at fivedifferent time points (at 30min and every hr). RESULTS: VE and HR significantly increased during hypoxia and hypoxic exercise (p<0.05). SaO2 and rSO2 decreased significantly during hypoxia (p<0.05), and decreased further during hypoxic exercise(p<0.05). Cognitive function declined during hypoxia (P<0.05), but hypoxic exercise did not alter cognitive function (p>0.05). Moreover, mood state was not changed significantly during pre- and post-exercise during hypoxia (p>0.05). CONCLUSION:These data suggest that normobaric hypoxia induces physiological changes, and in turn results in cognitive dysfunction. Low intensity exercise during normobaric hypoxia leads to further physiological changes, but does not impact cognitive performance.

▼ Hamstring strain injury (HSI) is a persistent cause of time lost in sports that involve high speed running. Clinicians working with sports injuries are therefore often faced with the task of HSI rehabilitation, with the simultaneous aims of minimising time to return to play (RTP) and risk of re-injury. Following rehabilitation and RTP clearance, previously injured hamstrings display elevated risk of re-injury likely, in part, due to persistent deficits in eccentric knee flexor strength and biceps femoris long head (BFlh) fascicle length. Elevated re-injury risk and persistent deficits in hamstring muscle structure and function suggest inadequacies in current rehabilitation practices. The overarching aim of this program of research was to attempt to improve HSI rehabilitation practices. The aim of chapter 3 was to systematically review criteria used to guide HSI rehabilitation progression and determine RTP clearance. The review identified a wide variety of criteria, which were used to progress HSI rehabilitation across the nine included studies. By far the most common guideline was to only perform and progress HSI rehabilitation in the complete absence of pain, despite the fact that such recommendations have never been compared to an alternative approach. Objective criteria were rarely implemented as part of rehabilitation progression and RTP decision making, especially where knee flexor strength was concerned. Three of the nine studies did implement isokinetic dynamometry as an objective measure of knee flexor strength, which is a lab-based methodology rarely available to clinicians dealing with HSI rehabilitation. As such, the need to develop objective measures of knee flexor strength, which could be implemented by clinicians during HSI rehabilitation, was identified. The primary aim of chapter 4 was to establish the test re-test reliability of a novel apparatus capable of objectively measuring knee flexor strength during a range of hamstring exercises commonly implemented during HSI rehabilitation. Secondary to this, chapter 4 aimed to investigate whether this apparatus could identify between-leg deficits in previously injured hamstrings during these exercises. The apparatus displayed moderate to high test re-test reliability for isometric knee flexor strength (ICC = 0.87 to 0.92), peak rate of force development (RFD) during isometric contraction (ICC = 0.87 to 0.95) and mean force impulse during the eccentric slider exercise (ICC = 0.83 to 0.90). Previously injured hamstrings displayed large deficits (d range = -0.88 to -1.09) in mean force impulse during the unilateral eccentric slider isometric knee flexor strength and peak RFD. The novel apparatus provides clinicians with an objective tool to monitor knee flexor strength during exercises commonly implemented throughout rehabilitation. Further to improving objective measures of knee flexor strength, chapter 5 aimed to provide clinicians with exercise-specific guidelines for the progression of a HSI rehabilitation protocol with an…
