BACKGROUNDː Facemask use has been recommended during physical activity to prevent spreading and contracting the virus that causes COVID-19. There have been concerns about negative physiological and perceptual effects of mask-wearing, especially during higher-intensity activities. Emerging research suggests there is a minimal impact of wearing a surgical mask on physiological responses across a wide array of exercise intensities and modalities. However, there are no published data regarding the impact of surgical mask use in hot or temperate environments during high intensity interval exercise (HIIE). Therefore, the purpose of this study was to investigate the effects of surgical mask use during …
The Effect Of Repetition Tempo On Training Volume, Heart Rate, Blood Lactate, And Muscle Oxygenation When Time Under Tension Is Matched In Recreationally-Trained Lifters, Zachary A. Mang
Health, Exercise, and Sports Sciences ETDs
It is commonly reported that resistance training (RT) with slower-repetition tempos leads to greater metabolic stress because they increase the time under tension (TUT) during sets of exercise. However, little information is available on the effect of different repetition tempos on blood lactate concentration, muscle oxygenation, and heart rate (HR) when TUT and proximity to concentric muscular failure are matched during lower-body RT. In a repeated-measures, cross- over design, 11 recreationally-trained females (n = 5) and males (n = 6) performed five sets of belt squat under the following conditions: Slow-repetition tempo (SLOW; 10 reps with 4:2 second tempo) and …

Purpose: To examine the effect of high intensity interval work (HIIW) and moderate intensity continuous work (MICW) patterns on markers of acute kidney injury (AKI) and kidney damage in a hot environment. Methods: Nine males completed two hours of physical work in a hot environment, performing either HIIW [2 minutes at 80% maximum oxygen consumption (VO2max) and 3 minutes at 30% VO2max] or MICW. Blood and urine samples were collected immediately before (Pre) and after (Post), one hour (1hr Post), and 24 hours after (24hr Post) the trials. Urine flow rate (UFR), osmolality (Uosm), and …
Studying Wash-Out During Professional Socializaton, Christopher Mellor
Studying Wash-Out During Professional Socializaton, Christopher Mellor
Health, Exercise, and Sports Sciences ETDs
Teacher washout can disrupt teacher effectiveness and undermine the espoused pedagogy in teacher education programs. Teacher washout occurs once an individual occupies a teaching role after formal training but corresponds with the potency of teacher education programs and K-12 experiences. Teacher washout literature is limited and does not address the socialization process of formal training. The following two hybrid dissertation studies examine washout, wash-in, and never washed-in. By doing so, we can expand the definition of washout and gain helpful insights on the perceptions of pre-service teachers. Implications from these studies provide faculty with proposals for change to decrease the …
Fear Of Failure In Brazilian Jiu Jitsu Practitioners, Frederick J. Williams Jr
Fear Of Failure In Brazilian Jiu Jitsu Practitioners, Frederick J. Williams Jr
Health, Exercise, and Sports Sciences ETDs
The purpose of this study was to understand the lived experiences of Brazilian Jiu Jitsu (BJJ) practitioners and the role that failure plays in their sport. Four male BJJ practitioners, three of which had obtained the rank of black belt and one purple belt participated in the study. Guided by Interpretive Phenomenological Analysis (Smith et al., 2009), three semi-repeated interviews and a singular journal entry were completed with each participant. The final analysis of the interviews and journal entries provided insight into the importance of community and failure as it pertains to personal growth, and the role coaches and teammates …
From Vision To Reality: Building Community-Based Adaptive Sports And Fitness Facilities Across The United States, Mary Beth Schubauer
From Vision To Reality: Building Community-Based Adaptive Sports And Fitness Facilities Across The United States, Mary Beth Schubauer
Health, Exercise, and Sports Sciences ETDs
People with physical disabilities face multiple barriers to activity and sports participation. This study aims to fill a gap in the literature by describing how community-based adaptive sports and fitness facilities are built in communities in the United States. Structured interviews of 11 participants, facility tours, and review of documents and photographs, are incorporated in the data collection and analysis. Understanding the necessary components for facility accessibility for people with disabilities also assists in ease of use by other community members. Three main concepts emerged from the analysis: incorporating viewpoints of people with disabilities in planning stages, use of universal …
Is The Skeletal Muscle Hypoxic Response To Exercise Different Between Endurance Trained And Untrained Individuals?, Roberto C. Nava, Zachary Fennel, Zachary Mckenna, Quint Berkemeier, Flávio De Castro Magalhães, Michael Deyhle, Fabiano Amorim, Christine Mermier

It was previously hypothesized that endurance exercise training blunts the hypoxia inducible factor 1 (HIF-1) response to acute exercise. We investigated whether training status influences the skeletal muscle HIF-1 response to acute exercise. 7 endurance athletes and 8 untrained controls performed a bout of cycling exercise. Skeletal muscle protein levels of HIF-1α and its inhibitors, prolyl hydroxylase 2 (PHD2), factor inhibiting HIF (FIH) and von Hippel-Lindau (VHL) were measured pre, post and 3h post-exercise. HIF-1 target gene expression was assessed via rtPCR and RNA-sequencing. Baseline protein levels of FIH and PHD2 were greater in the trained group. The exercise-induced increase …
Sex Differences In Running Performance: The Role Of The Anaerobic Speed Reserve In Female Middle-Distance Running, Lydia Charlotte Hallam
Sex Differences In Running Performance: The Role Of The Anaerobic Speed Reserve In Female Middle-Distance Running, Lydia Charlotte Hallam
Health, Exercise, and Sports Sciences ETDs
Middle-distance running is an interesting domain in which to study sex differences in athletic performance because of the varied metabolic, mechanical and tactical demands. The Anaerobic Speed Reserve (ASR) represents the difference between an athlete’s maximal sprint speed (MSS) and maximal aerobic speed (MAS). The ASR and MSS are key determinants of elite male 800m performance (Sandford et al., 2018); however, the role of the ASR in female middle-distance running is unclear, considering sex differences in physiology, mechanics and competition factors. We found that sub-groups of female middle-distance runners could be distinguished using the ASR and speed reserve ratio (SRR …
