The Longitudinal Effects Of Beta-Alanine On Punch Power, Punch Frequency, And Fatigue In Female Amateur Fighters, Rodger Wayne Stewart
Graduate Theses and Dissertations
Beta-alanine is a non-essential amino acid typically obtained in the diet via high-protein foods (beef, chicken, pork, and fish) and produced in the confines of the liver. BA is a precursor to the cytoplasmic dipeptide carnosine (beta-alanylhistidine). Carnosine is found in high concentrations in human skeletal muscle where it plays a key role in intracellular pH buffering. Research indicates BA supplementation increased punch power, punch frequency, and lactate concentrations in male amateur fighters after 28-day supplementation. There are currently no studies evaluating the effects of BA on boxing performance variables in women. Therefore, the purpose of this study was to …
Satellite Cell Behavior In Cyclists Following Intensified Training With And Without Protein Supplementation, Alec I. Mckenzie
Satellite Cell Behavior In Cyclists Following Intensified Training With And Without Protein Supplementation, Alec I. Mckenzie
Masters Theses, 2010-2019
PURPOSE: The objectives were to determine the satellite cell (SC) response among endurance-trained cyclists (n=8; VO2max: 63.1 ± 8.4 mL/Kg/min)to a period of intensified training (ICT) (10 days) and 10 days of recovery (RVT), with and without protein supplementation. METHODS: Muscle biopsies were obtained from the vastus lateralis prior to- and immediately following ICT and RVT. Fluorescent microscopy was used to analyze SCs and myosin heavy chain I and IIa (MHC I and IIa). Data were analyzed using magnitude-based inferences. RESULTS: MHC I SCs were exceptionally abundant at baseline (38 ± 20 SCs/100 fibers). MHC I SC count …
