The Longitudinal Effects Of Beta-Alanine Supplementation On Isometric Strength, Time To Exhaustion, And Lower-Body Isometric Torque In Female Masters Athlete Cyclists, Jordan Mckenzie Glenn Jul 2015

The Longitudinal Effects Of Beta-Alanine Supplementation On Isometric Strength, Time To Exhaustion, And Lower-Body Isometric Torque In Female Masters Athlete Cyclists, Jordan Mckenzie Glenn

Theses and Dissertations

Within the population of aging individuals exists a subset of competitive seniors or masters athletes (MA). As masters-level competition increases in popularity, MA must find methods to enhance individual athletic performance. Beta-alanine (BA) is an amino acid used to enhance physical capability based on ability increase intramuscular carnosine concentrations. Older adults and females have naturally lower carnosine levels compared to age- and gender-matched counterparts and may experience enhanced benefits from BA supplementation. Purpose: Therefore, the purpose of this investigation was to examine the longitudinal effects of BA supplementation on isometric handgrip strength (HG), time to exhaustion (TTE), total work completed ...


Relationally-Autonomous Reasons As A Predictor Of Collegiate Athletic Performance, Josef Max Katzman Jan 2015

Relationally-Autonomous Reasons As A Predictor Of Collegiate Athletic Performance, Josef Max Katzman

Online Theses and Dissertations

The current proposed study examines a concept that has been looked at before but now using a new specific population. Previous research examined shows that reasons for motivation affect goal attainment and success. The current study is looking at how relational autonomous reasons for motivation play a role in goal attainment in athletes. Eastern Kentucky University athletes were administered a short questionnaire and their previous athletic performance was used as well. The two sets of data were then used to examine the relationship between the two variables. The results of the study showed a positive correlation between Relationally-Autonomous Reasons (RAR ...


An Experimental Investigation Of Autonomy Support Versus Thwart In An Exergaming Context, Amanda Joy Weathers-Meyer Jan 2015

An Experimental Investigation Of Autonomy Support Versus Thwart In An Exergaming Context, Amanda Joy Weathers-Meyer

LSU Master's Theses

Considerable literature in self-determination theory (SDT) establishes satisfaction of basic psychological needs related to competence, autonomy, and relatedness as important determinants of well-being and motivation. Despite the abundance of SDT literature, few studies provide an investigation of autonomy support and autonomy thwart within an experimental design. Using SDT as a guiding framework, the effects of autonomy support (AS) versus autonomy thwart (AT) were examined within an exergaming context. Specifically, this study investigated the impact of autonomy support / thwart on five variables: perceived autonomy need satisfaction and autonomy thwart, affect, game performance, and willingness to recommend the study to others. Students ...
