The IMS consists of hip and wrist acceleration sensors, two piezoelectric respiration sensors on the …

Load Carriage Distance Run And Pushups Tests: No Body Mass Bias And Occupationally Relevant, Paul M. Vanderburgh, Nicholas S. Mickley, Philip A. Anloague, Kimber Lucius

Health and Sport Science Faculty Publications

Recent research has demonstrated body mass (M) bias in military physical fi tness tests favoring lighter, not just leaner, service members. Mathematical modeling predicts that a distance run carrying a backpack of 30 lbs would eliminate M-bias. The purpose of this study was to empirically test this prediction for the U.S. Army push-ups and 2-mile run tests. Two tests were performed for both events for each of 56 university Reserve Offi cer Training Corps male cadets: with (loaded) and without backpack (unloaded). Results indicated signifi cant M-bias in the unloaded and no M-bias in the loaded condition for both events. …

Athletic Training Students' Ability To Identify Scapular Dyskinesis, Priscilla M. Dwelly

Graduate Theses and Dissertations

Scapular dyskinesis refers to abnormal movement patterns of the scapula, which have been associated with injury. Previous investigations have validated the scapular dyskinesis test as a visual assessment method using physicians, physical therapists, and certified athletic trainers. Through educational programs, athletic training students should be taught what scapular dyskinesis is and how to identify it. Therefore, the purpose of this investigation was to (a) evaluate entry-level graduate athletic training students' ability to identify scapular dyskinesis, (b) assess their reliability, and (c) determine if they were able to correctly identify the muscles involved in rehabilitating an individual with scapular dyskinesis. Follow-up …

Physical Therapy Faculty Publications

Though popular, there is little agreement on what whole-body vibration (WBV) parameters will optimize performance. This study aimed to clarify the effects of age, sex, hertz, and time on four physical function indicators in community-dwelling older adults (N = 32). Participants were exposed to 2 minutes WBV per session at either 2 Hz or 26 Hz, and outcome measures were recorded at 2-, 20-, and 40-minute post-WBV. Timed get-up-and-go and chair sit-and-reach performances improved post-WBV for both sexes, were significantly different between 2 Hz and 26 Hz treatments (P ≤ 0.05), and showed statistically significant interactions between age and gender …

Plantar Pressure Distribution Differences In Physically Active Individuals With And Without Functional Ankle Instability During A Side Cut, J'Nai Pittman

Human Movement Sciences & Special Education Theses & Dissertations

Context: Functional ankle instability (FAI) is a popular condition in the physically active population. There is a surplus of evidence to demonstrate how FAI decreases proprioception, balance, and overall athletic performance. However, to date there is no evidence that demonstrates how F AI correlates to alterations in plantar pressure distribution differences in a physically active population while completing athletic tasks. Objective: To assess differences in plantar pressure distributions while completing a side cut in individuals with and without FAI. Design: Observational case-control. Setting: Outdoor field turf and research laboratory. Participants: Fifty ankles from physically active individuals (FAI: age= 21.47±3.02 yrs; …

Acute Arginine Supplementation Fails To Improve Muscle Endurance Or Affect Blood Pressure Responses To Resistance Training, Beau K. Greer, Brett T. Jones

All PTHMS Faculty Publications

Dietary supplement companies claim that arginine supplements acutely enhance skeletal muscular endurance. The purpose of this study was to determine whether acute arginine a-ketoglutarate supplementation (AAKG) will affect local muscle endurance of the arm and shoulder girdle or the blood pressure (BP) response to anaerobic exercise. Twelve trained college-aged men (22.6 +/- 3.8 years) performed 2 trials of exercise separated by at least 1 week. At 4 hours before, and 30 minutes before exercise, a serving of an AAKG supplement (3,700 mg arginine alpha-ketoglutarate per serving) or placebo was administered. Resting BP was assessed pre-exercise after 16 minutes of seated …

Why Is There Still So Much Confusion About Vo2 Plateau? A Re-Examination Of The Work Of A.V. Hill, Richard Vincent Castle

Masters Theses

Maximal oxygen uptake (VO_2max) is regarded as the gold standard for assessing aerobic fitness. In 1923, Hill et al. proposed that VO_2max represents the maximal ability of the body to take in and consume O₂ during strenuous exercise. Recently, however, controversy has arisen over the issue of whether a leveling off, or "plateau" in VO₂ is necessary to verify attainment of VO_2max. Purpose: To compare two different VO_2max protocols and determine if both protocols show direct evidence of an upper limit on VO₂. Methods: Nine runners (18-35 years old) completed …

Self-Reported Exercise And Risk Of Osteoporosis In Prostate Cancer Patients Receiving Androgen Deprivation Therapy, Lori J. Mennen-Winchell

Loma Linda University Electronic Theses, Dissertations & Projects

Prostate cancer is stimulated to grow in response to testosterone. Androgen deprivation therapy (ADT) leads to chemical castration and suppression of prostate cancer cell production. Testosterone levels less then 300ng/ml decreases bone mineral density and could result in osteoporosis. Studies have shown that during the first year of ADT, fracture risk, mainly in hips and spine increases about 50%. In men, 40% of hip fractures result in death. Exercise may reduce the risk of osteoporosis and thus contribute to the prevention of hip and other fractures. There is limited data regarding whether exercise is associated with a reduced risk of …

Post-Exercise Hypotension In Brief Exercise, Jeremiah G. Bush

Masters Theses & Specialist Projects

The purpose of this investigation was to examine whether a single 10 minute bout of exercise, performed at multiple intervals throughout the day to equal 30 minutes, can effectively elicit post-exercise hypotension (PEH). Secondly, it is important to explore whether a light (40% VO2R) or moderate (70% VO2R) intensity is required to elicit PEH within 10 minutes. Subjects (N=11) completed a VO2max test utilizing the Bruce Treadmill protocol. Each subject returned within 3 – 5 days to complete two separate exercising trials. A counter balanced system was employed so that each subject did not perform the same intensity rotation (Counter …

The Effects Of A Lumbopelvic Hip Complex Conditioning Program On Dynamic Knee Valgus In Female Tennis Players, Katelyn Marie Roling

Graduate Theses and Dissertations

Female athletes have a four-to-six times greater risk of sustaining a lower extremity injury than their male counterparts (Hewett, 2000). One explanation for the discrepancy in injury rates is increased dynamic knee valgus angles caused by neuromuscular imbalances of the lumbopelvic hip complex (LPHC). The purpose of this study was to determine if implementing a LPHC conditioning program improved neuromuscular deficiencies. Seven female collegiate tennis players competitive at the NCAA Division I level volunteered for the study (19.7 + .95 years, 167.3 + 7.4 cm, and 60.72 kg + 6.71 kg). The subjects participated in a 16 week LPHC conditioning …

UNLV Theses, Dissertations, Professional Papers, and Capstones

Best practices for assessing developmental skills in young children focus on naturalistic observation in everyday settings, but the effects of environment on test scores, eligibility status and administration time have not been explored. The Peabody Developmental Motor Scales-Second Edition (PDMS-2) was administered to 34 children aged 18 to 59 months in natural and pull-out settings. PDMS-2 total, gross, and fine motor quotient (TMQ, GMQ, and FMQ) scores were significantly lower in the natural environment (p’s≤.014). Based on our results, more children would qualify for services when tested in natural environments using TMQ and GMQ scores. It also took significantly longer …

The Acute Effects Of Static Stretching Of The Gastrocnemius On Limits Of Stability In Young Adults Versus Elderly Adults, Matt Bugnet, Kirk Player

UNLV Theses, Dissertations, Professional Papers, and Capstones

Background and Purpose: Balance is an important part of everyday life for all individuals with many body systems interacting to achieve optimal balance. Proprioceptive organs aid in this interaction, while also acting as stretch receptors. Therefore, it is possible that stretching may influence the overall balance of the individual. The purpose of this study was to investigate the acute effects of stretching on dynamic balance of healthy young and elderly adults. The two groups were used to determine if stretching may discriminately affect balance at different ages.

Subjects: Thirty healthy adults between the ages of 18 and 35 …

UNLV Theses, Dissertations, Professional Papers, and Capstones

Duties of police officers include apprehending suspects, which may involve foot pursuit and firing a weapon at a suspect. Previous studies in biathletes and soldiers suggest that shooting performance is compromised when fatigue is present. Purpose: To investigate the effects of exercise-induced fatigue on shooting performance in police officers. Methods: Nine police officers fired five rapid-fire shots at three targets each with a fifteen second rest period in between each trail. Officers then exercised on a cycle ergometer to 85% maximum heart rate or voluntary fatigue. The pretest shooting was repeated post-exercise. Distances of 4 shots from the center of …

The Self: Your Own Worst Enemy? A Test Of The Self-Invoking Trigger Hypothesis, Bradley J. Mckay

UNLV Theses, Dissertations, Professional Papers, and Capstones

The self invoking trigger hypothesis was recently proposed by Wulf and Lewthwaite (2010) as the mechanism underlying the robust effects of attentional focus on motor learning and performance. The hypothesis suggests that causing individuals to access their self schema will negatively impact their ability to learn and perform a motor skill. The purpose of the present study was to provide an initial test of this hypothesis by causing one group of participants to activate their self schema in a straightforward manner. Participants (N = 32) were assigned to either a self-activated or control condition and asked to practice a wiffleball …
