Hematological Changes In Response To A Drastic Increase In Training Volume In Recreational Cyclists, Jessie E. Axsom

Senior Honors Projects, 2010-2019

Changes in blood volume contribute to improvement in VO2max with chronic endurance exercise training. Although hematological changes to chronic endurance training have been well documented, it has not been well established whether an increased volume of training in trained individuals preferentially affects plasma volume vs. red cell volume. To answer this question, we studied 8 female and 3 male recreational cyclists before and after exposure to drastic increases in training volume. Following the 10-week training period, mean Hct of the 10 subjects who completed the study significantly (p<0.05) increased from 42.9% to 48.45%. Mean Hb also increased significantly (p<0.05) from 14.6g/dL to 16.4 g/dL. The changes in Hct and Hb were not significantly (p>0.05) correlated with the change in self-reported weekly mileage (R = 0.13 …

Piano Performance Injuries And Preventions, Kristin N. Cordell

Honors Theses

Strength, flexibility, coordination, and determination are all words that come to mind when describing an athlete. Not only do these words apply to athletes, but also to musicians, especially pianists. Each of these characteristics must be found within a pianist in order to achieve success. Although musicians may not look like athletes with large, bulky muscles, they should be considered musician athletes as well.

Just as athletes can become injured during practice or performance, so can pianists. The difference is found in the methods of training each use. Athletes often undergo extensive training to prepare their bodies for intense performance. …

A Divided-Attention Timed Stepping Accuracy Task As A Procedural Learning Intervention Improves Balance And Functional Performance In Healthy Older Adults, Susan Joy Leach

LSU Doctoral Dissertations

For both healthy individuals and individuals at high risk of falling, certain environments, such as a dual-task situation, require more resources than others to prevent a loss of balance. Stepping assessment tasks can be used to predict falls, and it has been suggested that impaired voluntary stepping may be a contributing factor to falls (Lord & Fitzpatrick, 2001). In this research, a stepping task was used not as an assessment, but as a therapeutic intervention. The purpose of this research was to determine how training with a task that provides a procedural learning environment can affect balance and functional outcomes. …

The Use Endocrine Markers To Predict And Monitor Performance In Strengh [Sic] And Power Activities, Jason B. Winchester

LSU Doctoral Dissertations

Hormones are typically considered to be chemical messengers, which are designed to be released from specific cells where they are carried to their target tissues for binding to receptors. It is this binding of a hormone molecule to its specific receptor which allows for an action to occur (Hadley and Levine 2006). Testosterone is the predominant androgen in the majority of mammalian species and is largely responsible for regulation of reproduction and maintenance of sexual function. In addition, in adult mammals, T has multiple other roles including the growth of muscle and bone, hematopoesis, blood coagulation, development and regulation of …
