The Effect Of Various Body Positions On Performance Of The Isometric Mid-Thigh Pull, George K. Beckham
The Effect Of Various Body Positions On Performance Of The Isometric Mid-Thigh Pull, George K. Beckham
Electronic Theses and Dissertations
The purpose of this dissertation was to evaluate the effects of changing body position on the execution of the isometric mid-thigh pull (IMTP). Furthermore, while there is evidence to suggest that there is an effect of familiarization on performance of maximal strength tests, there has been no known research evaluating the effect of learning on the IMTP. The effect of familiarization was assessed by evaluating changes in variables obtained from the IMTP. Subjects did not statistically improve over the five IMTP testing sessions, regardless of the body position used, or if subjects had previous experience with weightlifting derivatives. This may …
Four Weeks Of Controlled Frequency Breathing Training Reduces Respiratory Muscle Fatigue In Elite College Swimmers., Alex Robert Burtch 1991-
Four Weeks Of Controlled Frequency Breathing Training Reduces Respiratory Muscle Fatigue In Elite College Swimmers., Alex Robert Burtch 1991-
Electronic Theses and Dissertations
Controlled frequency breathing (CFB) is a common swim training modality that involves holding one’s breath for ~12 strokes before taking another breath. We sought to examine the effects of CFB training on reducing respiratory muscle fatigue (RMF). Elite swimmers (n = 25) were divided into either the CFB or a group that breathed regularly, every ~3rd stroke. The training intervention included 16 sessions of 12x50-m repetitions with either breathing pattern. RMF was defined as the drop in maximal inspiratory mouth-pressure (MIP) between rest and 46 seconds after a 200 yard free-style swimming race (~114 seconds). Pooled results demonstrated a reduction …

Body Image Self-Discrepancies And Compulsive Exercise: Exploring The Role Of Approach And Avoidance Motivational Selves, Kristin A. Chandler
Electronic Theses and Dissertations
According to Brewer, Davis, Kalmbach, Kaptein, Katzman and Kirsch (1997), problematic exercise occurs in approximately 80% of anorexia nervosa patients and 55% of bulimia nervosa patients. Thus, a comprehensive understanding of unhealthy exercise is necessary for its assessment as well as eating disorder prevention and intervention. One term used to describe unhealthy exercise is compulsive exercise. Although compulsive exercise has been regarded as problematic in the development, treatment, and outcome of eating disorders, little research has investigated the risk factors for this behavior. Given the influence of body image disturbances on disordered eating and the relationship between compulsive exercise and …
