The Effects Of A Mirror On Cognitive Strategy And Performance Of A Muscular Endurance Task, Brianna M. Simmons
The Effects Of A Mirror On Cognitive Strategy And Performance Of A Muscular Endurance Task, Brianna M. Simmons
Electronic Theses and Dissertations
Context: Mirrors are common-place in exercise facilities, however, the effect the mirror has on cognitive strategy (i.e., where the mind’s at) and performance time has not been examined in a muscular endurance task (i.e., a wall sit). Objective: To determine, (1) the mirror’s effect on cognitive state during a wall sit to volitional exhaustion, (2) the mirror's effect on time to volitional exhaustion during a wall sit, and (3) the mirror’s effect on the participant’s rating of perceived exertion (RPE) during the wall sit. Design: Repeated measures design. Setting: Indoor exercise facility. Participants: Twenty resistance-trained Georgia Southern University Students (9 …
Performance Differences Between Two Groups Of Commercial Pigs Following Experimental Infection With Prrs Virus 1-7-4, Erin Little
Performance Differences Between Two Groups Of Commercial Pigs Following Experimental Infection With Prrs Virus 1-7-4, Erin Little
Electronic Theses and Dissertations
Porcine reproductive and respiratory syndrome virus (PRRSV) is the costliest swine disease in North America. Vaccines and management alone have not been effective in controlling this disease. Genetic selection for resilience may be a complimentary approach for controlling PRRSV. The objective of this study was to estimate performance differences between two groups of pigs from the same commercial line following infection with PRRSV 1-7-4: 1) pigs sired by boars selected based on a standard index (TN-S), which emphasized feed efficiency and carcass quality; and 2) pigs sired by boars selected based on an experimental index (TN-E), which emphasized feed intake, …
The Effect Of Delayed Onset Muscle Soreness On Jumping Mechanics And Performance, Ryan J. Engels
The Effect Of Delayed Onset Muscle Soreness On Jumping Mechanics And Performance, Ryan J. Engels
Electronic Theses and Dissertations
Background: Delayed onset muscle soreness (DOMS) is an exercise-induced muscle soreness resulting from high-intensity eccentric muscular contractions. DOMS appears to be more prevalent in athletes at the beginning of an athletic season or when new movements or exercise are first introduced. The acute effect of DOMS on jumping mechanics is currently unknown. PURPOSE: The purpose of this study is to determine the effect of delayed onset muscle soreness on vertical jump performance and jumping mechanics. METHODS: Twenty college aged, recreationally active males participated in this study (age: 21.54 ± 2.61; height: 1.82 ± 0.067; mass: 81.36 ± 9.53). Participants were …
The Effects Of Beetroot Juice On Vo2max And Blood Pressure During Submaximal Exercise, Jose M. Perez
The Effects Of Beetroot Juice On Vo2max And Blood Pressure During Submaximal Exercise, Jose M. Perez
Electronic Theses and Dissertations
Supplementation with beetroot juice (BR) has been shown to reduce blood pressure (BP) at rest and improve several performance parameters during submaximal and maximal exercise. BR effects on BP during submaximal exercise have not been investigated. Furthermore, the effects of BR on VO2max are inconclusive. The purpose of this study was to investigate the effects of BR on VO2max and BP during submaximal exercise. 20 healthy, recreationally trained volunteers (age 21.8±2.35 years, weight 75.10±10.62 kg, height 177.4±6.39 cm) participated in this study, which had a double-blind placebo controlled randomized crossover design. Participants began supplementation with either …
