Strength And Body Composition Changes Of Junior Hockey Players During The Competitive Season, Dan Marquette
Strength And Body Composition Changes Of Junior Hockey Players During The Competitive Season, Dan Marquette
Electronic Theses and Dissertations
Purpose: This study investigated the body composition and strength changes of NAHL junior hockey players across a competitive season. It was hypothesized that players would lose lean body mass loss from pre-season to end-season. The secondary hypothesis was that players would lose strength in relation to the anticipated loss in lean body mass. Methods: Outcome measurements were taken at pre-season, mid-season, and endseason points of a competitive NAHL junior hockey season (n = 15, age = 19.1 years). Body composition was measured using air plethysmography (BodPod) and strength was measured using isokinetic strength testing (Biodex). Results: No significant changes in …
The Effects Of Hip Rotation On Hip Abductor Muscle Activation During Lateral Band Walk Exercise, Gina M. Fritz
The Effects Of Hip Rotation On Hip Abductor Muscle Activation During Lateral Band Walk Exercise, Gina M. Fritz
Electronic Theses and Dissertations
BACKGROUND: Lateral band walks (LBW) have been used to strengthen hip abductors and decrease risk of lower extremity injuries. Several methods have been used to complete this exercise to determine which has the best outcome. PURPOSE: The purpose of this study is to compare muscle activation of the gluteus medius (Gmed), gluteus maximus (Gmax), and tensor fasciae latae (TFL) during straight leg LBW exercises performed using three different hip positions: 30-degree internal rotation, 30-degree external rotation, and a neutral hip position. METHODS: Thirty-seven recreationally active participants (10 male, 27 female; age=21.4±2.2 yr; mass=71.4±13kg; height=1.7±0.1 m) completed this study. Surface EMG …
Recreational Female Crossfit Athletes And Low Energy Availability, Alison Kuch
Recreational Female Crossfit Athletes And Low Energy Availability, Alison Kuch
Electronic Theses and Dissertations
CrossFit is a demanding sport in which athletes perform constantly varied, functional movements at a high intensity, therefore requiring an adequate energy availability to avoid negative health and performance consequences. The purpose of this study was to assess risk of low energy availability (low EA) (phase 1) among recreational, female CrossFit athletes and measure and calculate energy availability using a 7-day dietary to measure energy intake (EI) and exercise energy expenditure (ExEE) (phase 2). In phase 1, using the LEAF-Q (Low Energy Availability in Females Questionnaire), 49% of survey respondents (n=149) were found to be at risk of low EA. …
