Effect Of Transcranial Direct Current Stimulation (Tdcs) On Maximal Voluntary Isometric Strength And Endurance Of The Elbow Flexors, Benjamin Kan

Theses: Doctorates and Masters

The present study investigated the effects of transcranial direct current stimulation (tDCS) on maximal voluntary contraction strength (MVC) and the time to failure (TTF) of an isometric muscle endurance test of the elbow flexors. Prior to the main study, the test-retest reliability of MVC and TTF measures was investigated using 10 men (33.2 ± 9.4 y) for the measurements separated by 60 min (within-day) and one week (between-day). Coefficient of variation (CV), Intraclass correlation (ICC, R), a paired t-test and the Bland-Altman plots revealed that TTF at 30% MVC task was reliable, and was able to detect a possible effect …

Feedback Control For Exergames, Jeff Sinclair

Theses: Doctorates and Masters

The concept of merging exercise equipment with video games, known as exergaming, has the potential to be one of the main tools used in addressing the current rising obesity epidemic. Existing research shows that exergaming can help improve fitness and additionally motivate people to become more active. The two key elements of attractiveness - how much people want to play or use the exergaming system; and effectiveness – how effective the exergaming system is in actually increasing or maintaining physical fitness, need to be maximised to obtain the best outcomes from an exergaming system; we put this forward as the …

Load Carriage And Its Force Impact, Robin Orr, Rodney Pope, Verenina Johnston, Julia Coyle

Rodney P Pope

Extract:
Just as history records that military personnel have been carrying heavy loads for over two millennia (Orr, 2010), so too does it show their impact on military force sustainment and combat effectiveness. Around 800BC, the heavy loads carried by Assyrian soldiers reduced their mobility and led them to experiment continually with their shields in order to lighten their loads (Gabriel, 2002). Around 400BC, the long marches of Cyrus’ ‘infamous 10,000’, an army of Greek mercenaries accompanied by Xenophon, would have resulted in numerous stress fractures, torn ligaments, muscle damage, blisters and abrasions. While some of these injuries can be …

A Conceptual Model Of Academic Success For Student-Athletes, Keith Harrison

Dr. C. Keith Harrison

Concern over the academic talent development of Division I student–athletes has led to increased research to explain variations in their academic performance. Although a substantial amount of attention has been given to the relationship between student–athletes and their levels of academic success, there remain critical theoretical and analytical gaps. The purpose of this article is to develop a conceptual model to understand and explain the cumulative processes and characteristics—as a whole and in stages—that influence academic success for Division I student–athletes. Research on student–athletes and academic success is reviewed and synthesized to provide a rationale for the basic elements of …

Effects Of A Simulated Tennis Match On Lymphocyte Subset Measurements, Holly Kell

Masters Theses & Specialist Projects

Research has shown that maximal exercise has a significant effect on cells of the immune system. Specifically, lymphocyte count increases during exercise and decreases to a value lower than baseline following an acute exhaustive bout of exercise. The overall lymphocyte response is well characterized, however, the ability of exercise to affect lymphocyte subfractions is unknown to our knowledge. The purpose of this study was to assess and evaluate the affects of a simulated tennis match across two sessions on lymphocyte subsets.

Initial measurements such as age, height, weight, skinfold analysis, and heart rate were recorded for each player, as well …

The Physical Activity Patterns And Constraints Of Diverse Female College Students, Kathleen Victoria Minkel

UNLV Theses, Dissertations, Professional Papers, and Capstones

Diverse college aged females from a public university in the southwest were asked to participate in an online survey to determine their constraints to physical activity, as well as their current activity level. The groups were compared to establish the differences among the minority groups. Raymore, Crawford, and Godbey’s Hierarchical Model of Constraints was used as a framework when creating the survey. Data analysis showed only one significant difference among the racial/ethnic groups, when looking specifically at the intrapersonal, interpersonal, and structural constraints categories. Hispanic women differed significantly from Caucasian women in their perception of interpersonal constraints on their physical …

Caffeine Supplementation And Moderate Intensity Exercise Modulates The Cytotoxic Lymphocyte Subset (Cd+8) In Naive And Tolerant Individuals, Elizabeth Ann Fedor

Masters Theses & Specialist Projects

The purpose of this investigation was to determine the effects of caffeine supplementation on caffeine tolerant and caffeine naïve individual’s lymphocyte counts, apoptosis and migration levels. In addition, effects of exercise on post-caffeine ingestion lymphocyte counts, apoptosis and migration levels were determined. It was hypothesized that caffeine would alter the immune system cell counts, but that exercise would be able to restore the immune system to homeostasis. Seventeen Western Kentucky University students were tested (males n=7, females n=10; n=7: caffeine tolerant= 200mg or more per day group, n=9: caffeine naïve= 50mg or less per day group). In this double-blind investigation, …
