Participants within two different exercise groups were assessed at two time points, 6 months apart. Group and longitudinal invariance was established for a novel, 8-item version of the PACES. The shortened, psychometrically sound measure provides researchers and practitioners an expedited and reliable instrument for assessing the enjoyment of physical activity.

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. …

Exercise Intensity As A Determinant Of Exercise Induced Hypoalgesia, Karen Y. Wonders, Daniel G. Drury

Health Sciences Faculty Publications

The purpose of this study was to examine pain perception during and following two separate 30-min bouts of exercise above and below the Lactate Threshold (LT). Pain Threshold (PT) and Pain Intensity (PI) were monitored during (15 and 30 min) and after exercise (15 and 30 min into recovery) using a Cold Pressor Test (CPT) and Visual Analog Scale (VAS) for pain of the non-dominant hand. Significant differences in PT scores were found both during and after exercise conditions. Post hoc analysis revealed significant differences in PT scores at 30 min of exercise (P=0.024, P=0.02) and 15 min of recovery …

Systematically Controlling For The Influence Of Age, Sex, Hertz And Time Post-Whole-Body Vibration Exposure On Four Measures Of Physical Performance In Community-Dwelling Older Adults: A Randomized Cross-Over Study, Harold L. Merriman, C. Jayne Brahler, Kurt Jackson

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 …

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 …

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; …

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 …

Evidence-Based Practice In Clinical Athletic Training Education, Dorice A. Hankemeier

Human Movement Sciences & Special Education Theses & Dissertations

Evidence-Based Practice (EBP) concepts are becoming more prevalent in the educational curricula of nursing, medicine, physical therapy, and athletic training. The infusion of EBP in the clinical education experience of students has been slow especially in athletic training. The aim of Project I was to investigate approved clinical instructors (ACIs) experience and implementation of EBP with students through emergent design qualitative interviews. Project II was designed to develop and establish the reliability of the Evidence-Based Concepts Assessment (EBCA) to assess athletic trainers' perceived importance, attitudes & beliefs, knowledge, confidence, accessibility, and barriers of EBP. Project III investigated the importance, knowledge, …

Older Athletes' Perceived Benefits Of Competition, Rylee A. Dionigi, Joseph Baker, Sean Horton

Human Kinetics Publications

Intense sport competition is typically associated with young people. Also, much of the literature on exercise for older adults focuses on benefits derived from regular physical activity, such as walking, dancing and fitness classes, and suggests that one should avoid extremely strenuous exercise. The rising phenomenon of older people competing in sport presents a challenge to these assumptions. In 2009, approximately 28,000 athletes from 95 countries gathered in Sydney, Australia to compete across 28 different sports at the World Masters Games. We interviewed 44 competitors (23 females, 21 males; aged 56-90 years; M=72) about what they gained from competing in …

Force Characteristics In Different Shoe Designs, Bryson Nakamura

Summer Research

Women’s shoes are known to be constructed from the same parameters as men’s shoes but on a smaller scale. However, foot and gait characteristics are different between genders The purpose of this study was to determine if mid-sole design has an effect on ground reaction force characteristics during running, cutting and jumping motions. Twenty-two apparently healthy female (73.8±8.4 kg; 1.74±0.06 m) and seven male (73.5±5.3 kg; 1.68±0.02 m) current or recently graduated NCAA Division III athletes voluntarily participated in this study. Subjects wore four shoes with different mid-sole designs while performing five different actions: running, cutting, shuffling, back cut and …

Psychosocial Aspects Of Physical Activity And Fitness In Special-Population, Minority Middle School Children, Jeffrey J. Martin, Nate Mccaughtry, Anne S. Murphy, Sara Flory, Kimberlydawn Wisdom

Kinesiology, Health and Sport Studies

Special-population research predicting physical activity (PA) and fitness with minority middle school children from at-risk environments is rare. Hence, the purpose of our investigation was to evaluate the ability of important social cognitive and environment-based measures to predict PA and fitness with children with developmental delay, cognitive, and emotional impairments. Children (N = 89, ages 11-15) completed questionnaires assessing social cognitive and environment-based constructs, self report PA, and completed fitness testing. Correlational results supported some hypotheses. The descriptive and correlational results also indicated commonalities with similar research on non special-population minority middle school children from at-risk environments.

Knee Range Of Motion: Reliability And Agreement Of 3 Measurement Methods, Paul G. Peters, Michael A. Herbenick, Philip A. Anloague, Ronald J. Markert, L. Joseph Rubino

Physical Therapy Faculty Publications

We conducted a study to compare 3 methods of measuring knee range of motion: visual estimation by physicians, hand goniometry by physical therapists, and radiographic goniometry. We hypothesized that reliability would be high within and across all techniques. We found intrarater and interrater reliability to be satisfactory for visual estimation, hand goniometry, and radiographic goniometry. Interrater reliability across methods did not agree satisfactorily. Between-methods differences in estimating knee range of motion may result from variations in technique among physicians and physical therapists.
