A Divided-Attention Timed Stepping Accuracy Task As A Procedural Learning Intervention Improves Balance And Functional Performance In Healthy Older Adults, Susan Joy Leach Jan 2009

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 Jan 2008

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 …


Monitoring Stress During Training, Olivita Couso Jul 2007

Monitoring Stress During Training, Olivita Couso

Seton Hall University Dissertations and Theses (ETDs)

The highly stressful job of law enforcement personnel, rescue workers and soldiers requires them to constantly put to the test their previous training. In order too respond effectively under pressure, the training of these personnel must be preformed under conditions that elicit pressure. The research proposed in this thesis evaluates established training regimens for the degree of stressfulness instilled in trainees from physiological (hypothalamic-pituitary adrenal axis, autonomic nervous system) and psychological perspectives (anxiety). Subjects participating in SWAT and military training were recruited, as well as subjects having no prior SWAT or military training. Individual physiological stress responses measured included heart …


The Effects Of The Front Squat And Back Squat On Vertical Jump And Lower Body Power Index Of Division 1 Male Volleyball Players, Manu Hoani Peeni Jun 2007

The Effects Of The Front Squat And Back Squat On Vertical Jump And Lower Body Power Index Of Division 1 Male Volleyball Players, Manu Hoani Peeni

Theses and Dissertations

The purpose of this study was to compare effects of the front squat and back squat on vertical jump and lower body power index of division 1 male volleyball players. Eighteen NCAA Division 1 male volleyball players volunteered for this study and were assigned either to a back squat or a front squat training program group. Subjects followed the training program for 8 weeks. Counter-movement vertical jump (CMVJ) height and lower body power index were measured at 0, 4 and 8 weeks of the study. A 2x3 factorial ANOVA revealed no significant difference in CMVJ height and power index between …


The Time-Course Of Vascular Adaptations Following Localized Short Term Exercise Training, Jason David Allen Jan 2001

The Time-Course Of Vascular Adaptations Following Localized Short Term Exercise Training, Jason David Allen

LSU Doctoral Dissertations

This is a series of 3 experiments in the area of vasoreactivity. The first study investigated the stability and reproducibility of brachial artery flow-mediated dilation (BAFMD). Twenty-six healthy volunteers underwent 3 scans on 2 days, performed by 2 ultrasonographers, and analyzed by 2 readers. All subjects were tested between 7 and 11am after refraining from food and exercise. Average baseline diameter was 3.48±0.53mm, which increased to 3.71±0.57mm (6.58±4.15%) at peak dilation. ICCC's for days, testers and readers were 0.9188, 0.9394, and 0.8982 respectively. To detect a difference in vasoreactivity of 60% (two-tailed), e.g. 5% vasodilation versus 8% vasodilation, at 90% …
