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 Psychological Response To A Low Carbohydrate Ketogenic Diet In Combination With A Six-Week Strength Training Protocol, Matthew T. Thorp

Masters Theses, 2010-2019

The aim of the present study was to determine whether or not long-term adherence to a Low-Carbohydrate Ketogenic Diet (LCKD) combined with a powerlifting strength training protocol could produce a positive psychological response. This six-week randomized control trial consisted of a treatment (LCKD) group (7% carbohydrates, 50% fat and 45% protein) and a control (CON) group (ad libitum). Both groups completed a validated powerlifting training protocol, as well as the Hospital Anxiety and Depression Scale and the Profile of Mood States. Multivariate testing and general linear modeling statistical analyses were used to compare psychological response between groups (p < 0.05) and found that there was a significant decrease in anxiety over the duration of six-weeks among both groups. No other psychological responses, including negative responses, were found to be significant. All participants significantly improved one-repetition max bench press, back squat, and deadlift (p < 0.05). The main findings of this study suggest that some positive psychological responses exist from long-term LCKD adherence, as well as potential increases in strength performance.
