It describes how teachers can be more aware of this challenge before incorporating the use of technology into physical education and health classrooms.

Is Vigorous Exercise Training Superior To Moderate For Cvd Risk After Menopause?, Julia Orri, E. M. Hughes, D. G. Mistry, A. Scala

Kinesiology (Formerly Exercise and Sport Science)

Postmenopausal women have an increased risk for cardiovascular disease through many factors, such as a sedentary lifestyle and reduced heart rate variability (HRV). Endurance training improves coronary risk but the role of exercise intensity is unclear. The purpose of this observational study was to evaluate the effects of moderate versus vigorous exercise on cardiovascular disease risk in postmenopausal women. Thirty-six postmenopausal women who self-reported training at moderate (3–5.9 METS; n = 18; age 58.9 ± 4.4yr) or vigorous intensities ( > 6 METS; n = 18; age 59.7 ± 5.2yr) participated. C-reactive protein (CRP), HRV, VO2max, and stress (Perceived Stress Survey, …

The Association Between Romantic Relationships, Self-Efficacy And Sports Self-Efficacy In Female Athletes As Measured By Salivary Cortisol, Merideth Byl, Ivelina Naydenova

Journal of Counseling and Psychology

This study examined the difference between relationship self-efficacy and sport self-efficacy in female athletes (n=13) through surveys and salivary cortisol. The female athletes provided saliva samples for cortisol measurements through a baseline sample, a behavioral relationship efficacy test sample, and an athletic event sample. Results were gathered through self-reported answers to multiple surveys taken before or after playing Jenga®. The pattern of results supported the hypothesis that there is significant positive correlation between sport self-efficacy and relationship self-efficacy. We also found a significant positive correlation between relationship self-efficacy and relationship satisfaction, but only for male participants. The study’s …

Attenuating The Side Effects Of Caloric Restriction Through Exercise And Increased Protein Intake, Jay A. Petersen

Department of Nutrition and Health Sciences: Dissertations, Theses, and Student Research

The effects of caloric restriction (CR) on weight loss and health outcomes are documented, but few controlled studies have addressed its effect on performance. Fat free mass (FFM) is reduced during CR, which may impair performance. The purpose of this thesis was to explore the capacity of these strategies to attenuate the side-effects of calorie-restricted weight loss: Exercise, which preserves FFM during CR, may be employed to maintain performance in an energy-deficient state, and a high protein intake may work in combination with exercise to further protect FFM and performance. Two studies were utilized to address this purpose. In study …

Research outputs 2014 to 2021

This study examined the suitability of sigmoidal (SIG) and exponential (EXP) functions for modeling HR kinetics at the onset of a 5‐min low‐intensity cycling ergometer exercise test (5MT). The effects of training status, absolute and relative workloads, and high versus low workloads on the accuracy and reliability of these functions were also examined. Untrained participants (UT_abs; n = 13) performed 5MTs at 100W. One group of trained participants (n = 10) also performed 5MTs at 100W (ET_abs). Another group of trained participants (n = 9) performed 5MTs at 45% and 60% max (ET_{45 …}

Rock-Based Fisher Safety Promotion: A Decade On, Kevin Moran Ph.D.

International Journal of Aquatic Research and Education

In the 10 years from 2006 - 2015, seven percent of all drowning fatalities in New Zealand were the consequence of land-based fishing activity (Water Safety New Zealand, 2015). In 2006, a collaborative campaign was launched in the Auckland, New Zealand entitled the West Coast Fisher Safety Project. This paper reports on the findings of annual surveys from 2006-2015 to determine what impact, if any, the safety promotion has had. The most emphatic change in fisher behavior in the intervening decade has been the more frequent self-reported use of lifejackets (2006, 4%; 2015, 40%), and a gradual shift in …

Position Statement: The International Society of Sports Nutrition (ISSN) bases the following position stand on a critical analysis of the literature regarding the effects of diet types (macronutrient composition; eating styles) and their influence on body composition. The ISSN has concluded the following. 1) There is a multitude of diet types and eating styles, whereby numerous subtypes fall under each major dietary archetype. 2) All body composition assessment methods have strengths and limitations. 3) Diets primarily focused on fat loss are driven by a sustained caloric deficit. The higher the baseline body fat level, the more aggressively the caloric deficit …

Youth Program Adult Leader's Directive Assistance And Autonomy Support And Development Of Adolescents’ Agency Capacity, David Hansen, E. Whitney Moore, Nadia Jessop

Kinesiology, Health and Sport Studies

Developing a capacity for exercising agency is an important developmental task of adolescence. Many organized youth programs provide adolescents opportunities to build their capacity to exercise agency. The researchers tested hypotheses that adult youth program leader's directive assistance and autonomy support would promote adolescents’ capacity for agency. They surveyed 441 high school adolescents and 11 adult advisors from 10 Future Farmers of America chapters twice over 2 years. Adolescents self‐reported on their capacity for agency and advisors reported on each adolescent's capacity. Directive assistance and autonomy support correlated with the capacity for agency within both time points. Only autonomy support …

Objective: The consequences of age-related decline in the somatotropic axis of humans are complex and remain largely unresolved. We tested the hypothesis that hGH measurements of plasma by bioassay vs immunoassay from samples obtained from free-living, elderly individuals would reveal a dichotomy in GH activities that are correlated with the functional status of the donors, i.e. their healthspan.

Design: Forty-one men and women of advanced age (men: N=16, age, 80.5±6.5years; height, 173.1±6.9cm; body mass, 81.8±13.0kg) and (women: N=25, age, 80.7±7.2years; height, 157.7±6.0cm; body mass, 68.8±17kg), were recruited for a cross-sectional study. Participants filled out PROMIS (Patient-Reported Outcomes Measurement Information System, …

2017 Faculty Bibliography

A standardized fitness assessment is critical for the development of an individualized exercise prescription. Although the benefits of aquatic exercise have been well established, there remains the need for a standardized nonswimming protocol to accurately assess cardiorespiratory fitness (CRF) in shallow water. The present investigation was designed to assess (a) the reliability of a standardized shallow water run (SWR) test of CRF and (b) the accuracy of a standardized SWR compared with a land-based treadmill (LTM)test. Twenty-three healthy women (20 6 3 years), with body mass index (23.5 6 3 kg$m22), performed 2 shallow water peak oxygen consumption (V_ O2peak) …

Examination Of The Monoamine Oxidase A Gene Promoter On Motivation To Exercise And Levels Of Voluntary Physical Activity, Erin M. Kinney

Senior Theses

Purpose: The purpose of this study was to examine the genetic basis underlying voluntary exercise. Monoamine oxidase A (MAO-A) is an enzyme that acts on monoamine neurotransmitters, such as dopamine, to cause inactivation. There are several polymorphisms in the promoter region of the MAO-A gene, and these variations change transcriptional activity and the amount of MAO-A produced, leading to alterations in available dopamine levels. Interestingly, polymorphisms in MAO-A have been associated recently with physical activity level. This study sought to determine whether there is an association between motivation to exercise, levels of voluntary physical activity, and MAO-A gene polymorphisms.

Physical Therapy Faculty Publications

Background: An observational tennis serve analysis (OTSA) tool was developed using previously established body positions from three-dimensional kinematic motion analysis studies. These positions, defined as nodes, have been associated with efficient force production and minimal joint loading. However, the tool has yet to be examined scientifically.

Purpose: The primary purpose of this investigation was to determine the inter-observer reliability for each node between two health care professionals (HCPs) that developed the OTSA, and secondarily to investigate the validity of the OTSA.

Methods: Two separate studies were performed to meet these objectives. An inter-observer reliability study preceded the …

Could Titin Have A Role In Strain-Induced Injuries?, Craig Perrin, Kazunori Nosaka, James Steele

Research outputs 2014 to 2021

It has been known for some time that strain injuries occur through the excessive lengthening of a muscle. However, the precise mechanism for strain injury remains elusive and has been the subject of recent debate in the Journal of Sport and Health Science, but it seems sensible to consider mechanisms at the level of the muscle fiber. It was previously believed that damage was the result of non-uniform stretching of sarcomeres on the descending limb of the length–tension curve, with the weakest sarcomeres undergoing the greatest deformation and ultimately damaging the myofibril. This non-uniform lengthening was also believed to …
