Brain Derived Neurotrophic Factor Response During Endurance Cycle Training: Impact Of Carbohydrate And Protein Supplementation, Jordan L. Parker

Senior Honors Projects, 2010-2019

Purpose: Brain Derived Neurotrophic Factor (BDNF) is part of the superfamily of neurotrophins including: nerve growth factor (NGF), neurotrophin-3 (NT-3) and neurotrophin-4 (NT-4). Recent evidence suggests that aerobic activity can increase BDNF levels both during and following exercise. Likewise, dietary habits have been shown to alter BDNF levels. However, nothing is known about the effect of BDNF levels during aerobic activity under specific dietary interventions. The purpose of this study was to examine the effects of specific macronutrient supplementation on BDNF levels during aerobic exercise. Methods: We had the opportunity to determine BDNF levels in blood samples obtained from two …

American Kettlebell Swing And The Risk Of Lumbar Spine Injury, Steve Oikarinen

Honors Program Theses and Projects

CrossFit is a fitness routine that utilizes the American kettlebell swing in their workouts. The Russian swing has been the traditional swing movement performed with the kettlebell swung to chest height, but with the American swing the kettlebell is propelled to an overhead position, which may increase the risk for a lumbar spine injury. However, research has yet to evaluate the American kettlebell swing mechanics and its influence on spinal injuries. Therefore, the purpose of this study was to examine the kinematics of the lumbar spine from maximum hip extension to the overhead position of the American kettlebell swing with …

The Effect Of The Cyp1a2 -163 C>A Polymorphism On The Metabolism Of Caffeine And Effect On Performance, Gabrielle E. Giersch

Masters Theses, 2010-2019

Prior studies from our laboratory suggest that the -163 C > A polymorphism of the Cytochrome P450 (CYP1A2) gene influences the ergogenic effect of caffeine. Although this polymorphism has been known to influence the inducibility of hepatic CYP1A2 and the rate of caffeine metabolism, levels of caffeine and/or metabolites have never been reported in these aforementioned studies (1, 12, 16). Thus, a mechanistic link between the polymorphism and the ergogenic effect of caffeine is lacking. The purpose of this study was to determine if the CYP1A2 polymorphism affected caffeine metabolism between the genotypes (AA homozygotes and C allele carriers). Twenty male …

Are There Bad Wins And Good Losses? Outcome Effects In Sport, Richard Erik Inglis

Masters Theses, 2010-2019

Abstract

Outcomes have been shown to distort feeling states, performance evaluations, and subsequent performances. This retrospective distortion represents an outcome bias, a phenomenon that has been studied extensively in a wide array of disciplines and domains. However, despite their importance, the effects of outcomes have received little attention in the sport corpus. In an attempt to remedy this oversight, 60 participants with basketball experience were recruited to take part in a free throw shooting competition. Participants completed two rounds of 20 free throws. Following their first round, participants were randomly assigned to either a negative outcome (lose by one shot) …

The Effects Of The Fifa 11+ Warm Up Program In Female Collegiate Soccer Athletes, Stacey O’Neill

Graduate Theses

As of 2010 there were over 265 million registered soccer athletes worldwide, and in particular, the number of women players were rapidly increasing (Soligard, et al., (2010). Consequently, playing soccer accounts for approximately one quarter of all injuries in sport, and due to its nature of jumping, pivoting and cross-cutting, the majority of these are non-contact, lower extremity injuries. Therefore, playing soccer entails a substantial amount of injury risk for its participants. The purpose of this study was to investigate the effects of the FIFA 11+ Warm Up Program in collegiate female soccer athletes.

The Effect Of Descriptive Norms On Resistance Exercise Self-Efficacy In College-Aged Females 2016, Justin Kompf
