A Comparative Analysis Of The Vertical And Plyometric Style Depth Jump Using Electromyography (Emg), Robert M. Conatser

Masters Theses

The purpose of this investigation was to compare temporal data during the phases of jumping. Eight NCAA, Di vision I football players completed four jumps: three depth jumps from heights of 0.15 m, 0.30 m, and 0.46 m, and a standing vertical jump. Subjects were grouped according to height jumped. The dependent variables were phase time, amortization time, and time to peak EMG. Surface EMG synchronized with high speed video was used to analyze the response of six muscles used in the jumping movement. Findings indicated that subjects who consistently jumped higher spent more time in each phase of the …

The Effect Of External Heat And Humidity On Levels Of Perceived Exertion While Performing A Submaximal Bicycle Test, Erika E. Hanselman

Masters Theses

The effect of changes in environmental conditions on perception of the intensity of exercise using the Borg scale for rating of perceived exertion (RPE) was the focus of this study. Subjects (n= 10) recruited opportunistically from graduate classes in the Health, Physical Education and Recreation Department performed the test in a climate control chamber located in the Exercise Physiology lab at Western Michigan University. The submaximal test followed the protocol established by the American College of Sports Medicine (ACSM, 1991).

Each subject performed each of the four conditions three times. Conditions were assigned in random order to each subject. Perceived …

The Use Of Selected Anthropometric Measures In The Prediction Of A One-Repetition Maximum For The Bench Press Weight-Lifting Exercise, Gerald L. Thomas

Masters Theses

The purpose of this study was to determine if selected anthropometric measures would accurately predict a one-repetition maximum (1RM) for the bench press. Sixty-two college students, 29 males and 33 females, were measured on six selected anthropometric variables and the criterion measure, a 1RM for the bench press. The independent variables were upper arm circumference, chest circumference, wrist circumference, lean body mass, and a 10-repetitions maximum (10RM). Pearson product moment correlations and multiple regression analyses were calculated for all subjects and for each gender. Regression equations involving a number of different combinations of variables were explored. The results indicated the …

The Effect Of The Active Ankle Brace On Ground Reaction Forces, Andrew D. Howell

Masters Theses

The problem of this study was to determine the effect an ankle brace worn for stability had on ground reaction forces. Ground reaction forces present when performing a step down from a height of 8.0 in. while wearing an Active Ankle Brace were compared to the ground reaction forces when not wearing the brace. Subjects (N=50) were randomly assigned to a testing condition. A metronome set at a rate of 100 bpm controlled the walking cadence of the subjects. Subjects were told to walk with a normal gait pattern, at the required cadence, and to use a heel strike landing. …
