Exercise Science Faculty Publications

The purpose of this study was to examine the effects of a ballistic or non-ballistic concentric-only bench press (COBP) on subsequent plyometric push-up performance. Fourteen resistance trained men completed two separate one-repetition-maximum (1RM) testing sessions followed by three randomized experimental explosive push-up sessions. These sessions combined a heavy concentric bench press with plyometric push-ups. Using a series of 3 × 10 (condition × time) repeated measures ANOVA, comparisons were made between the effects of ballistic and non-ballistic bench presses on performance of plyometric push-ups to investigate push-up performance variables. Compared with the control condition, both ballistic and non-ballistic bench presses …

Player-Coach Perceptions Of Internal Load, Exertion, And Recovery In Collegiate Male Soccer Players, Michelle L. Eisenman

College of Graduate Studies: Theses & Dissertations

Periodization of athlete training load to improve performance and maximize recovery, while reducing injuries and overtraining, is essential in team sports. Understanding internal load responses and monitoring athlete exertion and recovery can help coaches during a competitive season. Recovery Status (PRS) and Rating of Perceived Exertion (RPE) are two subjective scales used to help quantify training load and recovery. These scales are more useful if there is an agreement between coaches (C) and players (P) assessment of intensity and recovery. PURPOSE: To assess subjective measures (PRS and RPE scores) from P and C during a 13-week competitive soccer season. Furthermore, …

The Effects Of Acute Exercise Intensity On Episodic Memory And False Memory, Emma Kate Dilley

Honors Theses

Previous experimental work demonstrates that acute exercise may enhance episodic memory performance. However, limited research has examined the extent to which acute exercise influences false memory production, and no studies, to date, have examined whether there is an intensity-specific effect of acute exercise and true and false memories. Thus, the present experiment evaluated the effects of acute exercise on episodic memory and false memory. A three-arm, parallel, between-group randomized controlled trial was employed, with participants (Mage = 20.8 years) randomized into a moderate-intensity exercise group (15-minute bout of treadmill exercise at 50% Heart Rate Reserve; N = 20), a high-intensity …

The Effects Of Acute Omega-3 Fatty Acid Supplementation On Delayed-Onset Muscle Soreness And Recovery, Colin A. Butler

College of Graduate Studies: Theses & Dissertations

Delayed-onset muscle soreness (DOMS) is the feeling of discomfort that occurs after being exposed to unaccustomed eccentric resistance training often resulting in diminished athletic performance. Previous research has shown positive effects with omega-3 fatty acid (O3FA) supplementation to ameliorate DOMS. The purpose of this study was to investigate the effects of acute O3FA supplementation on perceived muscle soreness, ratings of exertion, and recovery after a lower body resistance training protocol in college-aged males. A double blind, repeated-measures design was utilized with 10 healthy, college-age males. Participants were placed in the placebo (olive leaf oil) or experimental (O3FA) group, consuming 3,000 …

Although walking gait in sighted populations is well researched, few studies have investigated persons with visual impairments (VIs). Given the lack of physical activity in people with VIs, it is possible that reduced efficiency in walking could adversely affect activity. The purposes of this preliminary study were to (1) examine the biomechanics and energetics utilized during independent and guided walking in subjects with VIs, and (2) compare gait biomechanics between people with VIs and sighted controls.

Methods.

Three-dimensional motion capture and force platforms were used during independent and guided walking at self-selected speeds. Joint angles, moments, external work, and …

Chronic Low Intensity Continuous And Interval Training Prevent Heart Failure-Related Coronary Artery Stiffness, An Ouyang

Theses and Dissertations--Kinesiology and Health Promotion

Heart failure (HF) induced by aortic pressure over-load is associated with increased coronary artery stiffness. Perivascular adipose tissue (PVAT) and advanced glycation end products (AGE) both promote arterial stiffness. However, the mechanisms by which coronary PVAT promotes arterial stiffness and the efficacy of exercise to prevent coronary stiffness are unknown. The present study hypothesized both chronic continuous and interval exercise training would prevent coronary artery stiffness associated with inhibition of PVAT secreted AGE. Yucatan mininature swine were divided into four groups: control-sedentary (CON), aortic-banded sedentary heart failure (HF), aortic-banded HF continuous exercise trained (HF+CONT), and aortic-banded HF interval exercise trained …

Heart Rate Dynamics During And After Simulated Fire Ground Tasks: Effects Of Physical Fitness And Training, Anssi Ilmari Saari

Theses and Dissertations--Kinesiology and Health Promotion

Firefighting is a strenuous occupation that increases the risk of cardiovascular events. Greater levels of physical fitness and training improve firefighters’ occupational performance, but little is known whether they are related to lower physiological stress and recovery from fire ground tasks. Heart rate, heart rate recovery and heart rate variability have been used to evaluate physical stress in association with exercise and fire ground tasks. However, there is a paucity of research evaluating the effects of physical fitness and training on heart rate dynamics during a simulated fire ground test (SFGT). Therefore, the primary purposes of this study were to …

Circadian Rhythm Phase Shifts Caused By Timed Exercise Vary With Chronotype In Young Adults, J. Matthew Thomas

Theses and Dissertations--Kinesiology and Health Promotion

The circadian system controls 24-hour cycles of behavior and physiology, such as rest-activity and feeding rhythms. The human circadian system synchronizes with, or entrains to, the light/dark cycle (sunrise/sunset) to promote activity and food consumption during the day and rest at night. However, strict work schedules and nighttime light exposure impair proper entrainment of the circadian system, resulting in chronic circadian misalignment. Numerous studies have shown that chronic circadian misalignment results in poor health. Therefore, therapeutic interventions that could shift circadian rhythms and alleviate circadian misalignment could broadly impact public health. Although light is the most salient time cue for …

Effects Of Curcumin And Fenugreek Soluble Fiber Supplements On Submaximal And Maximal Aerobic Performance Indices In Untrained College-Aged Subjects, Jensen Goh Zhong Sheng

Theses and Dissertations--Kinesiology and Health Promotion

Submaximal exercise performance is, in part, limited by the accumulation of metabolic byproducts and energy system capacities. Curcumin and the combination of curcumin and fenugreek soluble fiber (CurQfen^®) have been shown to increase endogenous antioxidants and metabolic byproduct clearance as well as reduce inflammation and lipid peroxidation, and therefore, may enhance submaximal aerobic thresholds. In addition, there is evidence that the galactomannan component of fenugreek, used to enhance bioavailability of curcumin, may also have potential physiological effects related to the up regulation of free fatty acid oxidation Therefore, the purpose of this study was to examine the effects …

An Examination Of The Effects Of Bilateral And Unilateral Very Short-Term Dcer Training On Strength And Neuromuscular Responses Within The Lower Limb Bilateral Deficit, Mark Travis Byrd

Theses and Dissertations--Kinesiology and Health Promotion

The very short-term resistance training (VST) model, utilizing only 2-3 training sessions, has been used to examine early phase skeletal muscle, neural, and performance adaptations. The VST model has previously been used to examine these early phase adaptations in bilateral and unilateral, isometric, isokinetic, and dynamic muscle actions in the limbs of the upper- and lower-body. The bilateral deficit (BLD) is a phenomenon in which the sum of the forces produced unilaterally is greater than the force produced bilaterally during maximal contraction of the limbs. The appearance of a bilateral deficit has been be related to various factors; including training …

The Effect Of Loading Rate On Annulus Fibrosus Strength Following Endplate Fracture, John Mcmorran

Theses and Dissertations (Comprehensive)

Low back pain is the most prevalent cause of chronic pain for North Americans, and its correlation with endplate damage, and deficient mechanical properties in the annulus fibrosus (AF) makes this injury particularly concerning. To date, biomechanical alterations in the AF following endplate fracture have not been well described. Owing to the AF’s collagenous composition, and the intrinsic biomechanics of intervertebral discs (IVDs) during compression, it was hypothesized that the mechanical properties of AF specimens would show rate-dependent alterations in their tensile and adhesive strengths following endplate fracture. The purpose of the present study was to quantify the mechanical properties …
