Seasonal Variation In Anthropometric And Performance Variables In American Professional Soccer Players, Hannah Elizabeth Ramirez
Seasonal Variation In Anthropometric And Performance Variables In American Professional Soccer Players, Hannah Elizabeth Ramirez
Electronic Theses and Dissertations
BACKGROUND: Preseason is an essential component of sport; it prepares players physiologically for the beginning of the competitive season by allowing for improvements in performance and fitness variables. As the season progresses, the need to maintain an ideal performance state may be difficult due to accumulating training load. PURPOSE: The purpose was to determine the seasonal variation of power, agility, and body fat percentage (BF%) via a series of tests throughout the competitive season of American professional soccer players. METHODS: 23 male United Soccer League (USL) One players underwent a performance battery (akimbo vertical jump (VJ), reactive strength index (RSI), …

The Effects Of Chronic L-Carnitine And Carbohydrate Supplementation On Body Composition And Athletic Performance In Female Endurance Athletes., Melissa Eryn Stack
Electronic Theses and Dissertations
Purpose. The purpose of this study was to examine the effects of chronic L-carnitine and carbohydrate supplementation on body composition, perceived exertion, and athletic performance in recreationally-trained female endurance runners. Methods. On three separate occasions, twenty-one days a part, seven recreationally-trained female endurance runners performed a timed progressive treadmill test to exhaustion as well as a body composition assessment using the Bod PodÒ. Participants were randomly assigned to one of two groups – L-carnitine (LC) or L-carnitine plus carbohydrates (LC + CHO). The LC group consumed 2 g of L-carnitine L-tartrate and the LC + CHO group consumed 2 g …
Validation Of B-Mode Ultrasound Imaging As A Body Composition Measurement In Division I Football Players, Keagan Kiely
Validation Of B-Mode Ultrasound Imaging As A Body Composition Measurement In Division I Football Players, Keagan Kiely
Electronic Theses and Dissertations
The purpose of the current study was to validate the use of B-mode ultrasound as a method to estimate body composition in Division I football players. Body composition was estimated using ultrasound, 7-site skinfold and a 4 compartmental model (4C) using Bioimpedance spectroscopy (BIS) to estimate total body water (TBW) and air-displacement plethysmography (BODPOD®) to determine body density (Db) and dual x-ray absorptiometry (DEXA) for bone mineral content. Pearson’s product-moment correlation analyses were run to determine if there was a correlation between ΣSkinfold and ΣUltrasound and between ΣUltrasound and criterion 4C model. Strong positive correlations were observed between ΣSkinfold and …
