Contralateral Repeated Bout Effect Of The Elbow Flexors Not Observed In Young Women, Bailey Brown

Honors Theses

The contralateral repeated bout effect (CL-RBE) is known as a protective effect in which an initial bout of eccentric exercise reduces muscle damage in the contralateral limb after a similar bout of eccentric exercise. To our knowledge, previous studies on CL-RBE only recruited males or a mixture of both sexes. PURPOSE: To investigate the presence of the CL-RBE of the elbow flexors in women. METHODS: Twelve healthy women (20.9 ± 2.5 years) performed two bouts of 45 maximal eccentric contractions (ECC) of the elbow flexors using the opposite arm separated by 14 days. The isokinetic muscle strength (60°/sec) was measured …

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 …

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, …

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 Effects Of Concussion On Tandem Gait Performance With Secondary Cognitive Tasks, Angel Lomeli

Cal Poly Humboldt theses and projects

Identifying concussions occurs with a battery of cognitive and motor tests. However, these tests are performed independently as primary tasks. Research has demonstrated amplified motor differences due to concussion when performing simultaneous cognitive tasks (i.e. dual-tasks). The Tandem Gait Test (TGT) is used in concussion assessment and has only moderate sensitivity and specificity alone. The aim of this study was to determine the effect of concussion on TGT performance with secondary cognitive tasks. Six concussed participants (age 22.6 ± 2.8) and fourteen healthy participants (age 23.8 ± 2.7) were recruited through the North Coast Concussion Program within 13 days (7 …

Psychological Effects And Treatment Of An Injury On An Athlete: Suggested Treatment Plan For Athletic Trainers And Physical Therapist, Odell Miller

Honors Theses

Injuries that force athletes to lose participation in their sport and or training have a tremendous impact on their mental health. Mental health issues can be detrimental, but often times go unnoticed. For example in 2010, Kenny McKinley, a wide receiver for the Denver Broncos, was found dead after killing himself with a gun. After suffering a knee injury, he had become progressively depressed. Investigators reported that there are statements saying that McKinley didn’t know what he would do without football. According to NCAA’s Sports Science Institute (2017), the psychological response to injury can trigger mental health issues such as: …

Drowning Prevention: Define And Then Gather Evidence Or Gather Evidence To Define?, Nina J. Nyitrai, Suzi Edwards, Nicholas O'Dwyer

International Journal of Aquatic Research and Education

According to the World Health Organization, drowning fatalities are a neglected public health issue ranked as the third most frequent cause of unintentional death by injury. Data used to record drowning incidents are acknowledged as inaccurate. Recommendations on drowning prevention based on these data are currently not informed by accurate, detailed and reliable evidence. Two modifications to current practice are proposed: 1) an Aquatic Incident Report needs to be developed as an extension of the current workplace incident report to prompt for information commonly not included in current drowning reports; and 2) National Water Safety Plans should be modified to …
