Risk Management Perceptions And Preventive Practices Of Athletic Directors From Naia Schools, Yan Gioseffi

Health, Exercise, and Sports Sciences ETDs

The increase in the number of incidents associated with sports has led to the rise of litigation, and physical, emotional, and financial damage to stakeholders. Collegiate athletic directors (ADs) have the duty to keep their programs safe.

This study aimed to explore and understand the practices, perceptions, and experiences of ADs from National Association of Intercollegiate Athletics (NAIA) institutions regarding preventive risk management. As risk management is significantly new in the sporting industry, an exploratory study using a qualitative design, grounded in narrative inquiry was conducted using the D.I.M. Process as a guide to collect data from 10 NAIA ADs …

Laterality In The Power Five And Group Of Five Conferences In Women's College Softball, Jon C. Nachtigal

Health, Exercise, and Sports Sciences ETDs

Females in sport are under-represented in data and analysis when compared to their male counterparts. This disparity also applies to women’s softball in comparison to men’s baseball. To help fill this gap, this study evaluated the extent and impact of laterality in women’s college softball’s Power Five and Group of Five conferences from 2015-2017.

This study focused on the extent of a left-sided lateral preference in women’s college softball, possible interactions between throwing hand and batting preference, to what extent the platoon effect exists in the sport, and the extent of positional bias in the sport. As one of the …

A Comparison Of Video Conferencing And In-Person Health Coaching Approaches In Combination With Mhealth Devices On Weight Loss, Physical Activity, And Glycemic Control, Kelly E. Johnson

Health, Exercise, and Sports Sciences ETDs

Background: Compare health coaching efficacy on weight loss, physical activity, and glycemic control between individualized video conferencing (VC), in-person (IP) and control (CG) groups of adults with high BMI.

Methods: Thirty adults (BMI≥30 kg/m²) were randomly assigned to create three groups of 10 members each. Participants received a wireless accelerometer watch and weight scale to sync with their personal smartphones and downloaded apps. Participants assigned to VC and IP received weekly health coaching individualized based on data uploaded over the 12-wk intervention. Steps/day and weight loss were analyzed via analyses of covariance (ANCOVA). Between-group ANOVAs analyzed post-intervention changes …

Hemodynamic And Metabolic Responses During Self-Paced And Ramp Graded Exercise Testing Treadmill Protocols, Nicholas Mark Beltz

Health, Exercise, and Sports Sciences ETDs

Purpose: To investigate: 1) if a self-paced (SP) graded exercise testing protocol elicits similar and reliable maximal oxygen uptake (VO_2max) responses compared to a ramp (RAMP) treadmill protocol; 2) the impact of SP on cardiac output (Q), stroke volume (SV), and arteriovenous oxygen difference (a-vO_2diff); and 3) the metabolic response during SP through blood lactate (BLa^-) accumulation and ventilatory threshold (VT) attainment. Methods: Sixteen recreationally trained men (23.7±3.0 yrs) completed two separate treadmill graded exercise testing protocols. SP consisted of five 2-min stages (10 min total) of increasing speed based on the Borg …

A Comparison Of Exercise Responses During Acute Exposure To Hypobaria In Exercise Trained Males With Coronary Heart Disease And Healthy, Sedentary Males, David Lowell Parker

Health, Exercise, and Sports Sciences ETDs

This investigation was conducted to evaluate effects of acute altitude exposure on selected pulmonary, cardiovascular, metabolic, and psychological variables measured at rest, during, and after submaximal exercise. Comparisons were made between a group of men with coronary heart disease who were participants in an exercise reha­bilitation program (trained CHD's) and a group of healthy, asymptomatic, and sedentary individuals (HI's).

Nine male trained CHD's and 10 male HI's partici­pated in the study, which was conducted during an 8-week period. Initially, all subjects performed a maximal stress test on a bicycle ergometer at 1576m. Maximal values from this test were utilized in …
