Effects Of Varying Warmup Stimuli On Running Economy, Connor Bigenho
Effects Of Varying Warmup Stimuli On Running Economy, Connor Bigenho
Electronic Theses and Dissertations
Purpose: The purpose of this study was to determine the effects of two potentiating warm-up stimuli (weighted-vest strides and plyometrics) on running economy (RE) over short (5-10 minutes) and longer durations (30+ minutes) of exercise in trained distance runners. Methods: Five recreationally trained male runners were recruited to participate in this study. Each trial consisted of a 10-min self-paced warm-up on the treadmill followed by baseline RE test and baseline leg-stiffness. This was immediately followed by one of two intervention warmup protocols. The protocols consisted of either a series of plyometric movements, 6 x 10-sec strides with a …

Recovery Methodologies And High Intensity Interval Training, Blake W. Johnson, Malcom T. Whitehead
Electronic Theses and Dissertations
The purpose of this study was to determine recovery from Tabata bodyweight high intensity interval training (HIIT) exercise using different recovery assessment methodologies across 24- and 48-hour time intervals. Participants (23.2 ± 3.1 years old, 163.1 ± 19.9 lbs., and 22.8 ± 9.6 % body fat) consisted of 3 females and 7 males (n=10) Individuals who were recreationally trained (4+ days per week, 30+ minutes per day at moderate to vigorous intensity) and conducted both Trial A (24-hours between HIIT sessions) and Trial B (48-hours between HIIT sessions). Before and during each session, heart rate, countermovement jump, perceptual, …
Deception Of Resistance And The Effects On Muscular Fitness And Perceived Exertion, Tyler Mchenry
Deception Of Resistance And The Effects On Muscular Fitness And Perceived Exertion, Tyler Mchenry
Electronic Theses and Dissertations
Resistance training has been a popular tactic that individuals have used to increase muscular fitness for decades. Muscular fitness includes muscular endurance, strength, and power. However, limitations such as self-efficacy and the Central Governor Theory may influence individual maximal performance ability. One training tactic that has been rarely researched is the deception of resistance during exercise, which is assumed to increase performances in all aspects of muscular fitness and improvements in perceived effort. Inconsistent results have been concluded from previous studies that have examined the same topic. Therefore, the purpose of this study was to investigate the effect of resistance …
Effects Of Pre-Workout Caffeine Supplementation On Post-Exercise Hypotension, Shelby L. Gibbs
Effects Of Pre-Workout Caffeine Supplementation On Post-Exercise Hypotension, Shelby L. Gibbs
Electronic Theses and Dissertations
Post-exercise hypotension (PEH) is believed to play a major role in the antihypertensive health benefits of exercise. While it has been shown that resistance exercise is effective at eliciting PEH, commonly consumed sports supplements may attenuate or completely eliminate that response. Caffeine, a popular stimulant, is often consumed prior to exercise. Therefore, the purpose of this study was to investigate the effects of pre-workout caffeine supplementation on the post-exercise hypotensive response in adults with above normal blood pressure. Participants (n = 5) were recreationally resistance trained men and women who consumed placebo or caffeine (3 mg/kg bodyweight) 45-minutes prior to …
The Effects Of Resistance Deception On Muscular Strength, Muscular Endurance, And Perceived Exertion, Broderick L. Dickerson
The Effects Of Resistance Deception On Muscular Strength, Muscular Endurance, And Perceived Exertion, Broderick L. Dickerson
Electronic Theses and Dissertations
Resistance deception during training is a lightly researched topic and is seen as a modification that can potentially act on central control during exercise. Studies that have observed effects of deception while training have yielded mixed results. The effects of deception on strength, muscular endurance, and perceived exertion and the mechanisms of action that may elicit changes are still unclear. Therefore, the purpose of this study is to determine the effects of resistance deception on muscular strength, muscular endurance, and perceived exertion in a trained population. Eight participants finished the study and underwent four trials, one of which was a …
Comparison Of An Acute Bout Of Exercise To A Sugary Snack On Energy, Mood And Cognitive Performance, Erica Knowles
Comparison Of An Acute Bout Of Exercise To A Sugary Snack On Energy, Mood And Cognitive Performance, Erica Knowles
Electronic Theses and Dissertations
Low perceived energy and a decline in cognitive performance throughout the day are common issues, though exercise and food consumption are suggested to improve mood and cognition. The present study compares effects of acute exercise to consuming sugar on mood, energy, and cognitive performance. Subjects underwent blood glucose testing, completed an Abbreviated Profile of Mood States Questionnaire, and Automated Operation Span (OSPAN) and Digit Span tests to measure memory and attention. On two separate days subjects consumed candy or walked on a treadmill for 10 minutes, then measurements were repeated at 30-min, 60-min, and 120-min post. Two-way ANOVA over time …
Comparison Of Post-Activation Potentiation Methods On Power And Sprint Acceleration, Aaron Piper
Comparison Of Post-Activation Potentiation Methods On Power And Sprint Acceleration, Aaron Piper
Electronic Theses and Dissertations
Post-activation potentiation (PAP) is a stimulus used to enhance performance by performing specific interventions prior to subsequent explosive movements. The purpose of this study was to determine the effect of different PAP methods on power and sprint acceleration in resistance trained, college-aged men and women. A total of 13 subjects participated in the study. After determining back squat 1 repetition max, subjects returned for testing on separate days to complete one of four interventions (dynamic resistance, weighted plyometric, isometric, or control) in a randomized order. A standardized warmup was given, followed by a baseline countermovement jump (CMJ) and 20-meter sprint. …
Comparison Of Two Body Weight Screenings Of Self-Conscious Emotions And Coping, Rachel N. Nanez Ms.
Comparison Of Two Body Weight Screenings Of Self-Conscious Emotions And Coping, Rachel N. Nanez Ms.
Electronic Theses and Dissertations
Novel technologies are currently being utilized in fitness and clinical settings. However, there is not much research to examine the emotional responses to such screenings.
PURPOSE: To examine the group differences between the FIT3D and DXA protocol on emotional responses and the differences between weight classifications.
METHODS: The Body and Appearance-related Self-conscious Emotions Scale and WEIGHTCOPE were used to assess self-conscious emotions and intention to utilize 10 different weight-related coping strategies following the scans. Motivation was measured by a 10-point Likert scale measuring motivation pre and post scans.
RESULTS: There were no differences in motivation, affective response, or intention to …
Stop The Pricks: A Validation Study Of A Noninvasive Lactate Threshold Device, Rebecca M. Mcmorries
Stop The Pricks: A Validation Study Of A Noninvasive Lactate Threshold Device, Rebecca M. Mcmorries
Electronic Theses and Dissertations
ABSTRACT
Purpose: The aim of this study is to assess the validity of a noninvasive lactate threshold device (NID) to determine lactate threshold heart rate (LTHR) and aerobic threshold heart rate (AeTHR).
Methods: Twenty-one recreational athletes completed a personalized graded exercise test on a treadmill. All participants wore the noninvasive device and blood lactate samples were taken at the end of 3-minute stages. Lactate threshold heart rate and aerobic threshold heart rate were then calculated using four traditional methods and compared against the same heart rate values calculated by the device.
Results: No significant differences were found in lactate threshold …
