An Emg Comparison Of Muscle Recruitment Associated With The Wide Grip Pull-Up And The Lat Pull-Down Exercise, Marla S. Bauermeister

Masters Theses

The purpose of this study was to describe and compare the prime mover muscles used in the wide grip pull-up and lat pull-down exercises. Ten Western Michigan University students performed the 2 exercises, using a resistance equal to their body weight for 3 sets of 3 repetitions, with 2 min rest between sets. The 2nd repetition of each set was analyzed for each exercise. Research variables included phases (concentric, coupling, and eccentric), exercises, trials, and muscles. The dependent variables were relative time to peak recruitment, peak recruitment, and phase time. Findings revealed that the concentric and eccentric phases were slower …

Validation Of The Original And Modified Ymca Cycle Ergometer Tests, Joel V. Blakeman

Masters Theses

The problem of the study was to determine if a 3-point estimation procedure for the YMCA cycle ergometer submaximal test (YMOD) provided a more valid predictor of maximal oxygen consumption (VO2 max) than the recommended 2-point estimation YMCA procedure for male and female college students ages 18 to 25 years. Apparently healthy subjects (n = 21 females; n = 25 males) completed the ACSM maximal cycle ergometer test, the YMCA test, and the YMOD test. The reliability estimates of modified YMCA max scores, R = .39, was higher than the reliability estimate from the YMCA, R = -.80. ANOVA results …

The Effects Of Chromium Picolinate Supplementation On Body Fat, Lean Body Mass, And Respiratory Exchange Ratio, Matthew K. Beaty

Masters Theses

The purpose of this study was to investigate the effects, on college-age males, of ingesting chromium picolinate over a 6-week period when administered as a supplement to their diet. Fifty males, ages 18 to 25 years, had their respiratory exchange ratio (R), body fat percentage, and lean body mass measured prior to and following a 6-week supplementation period. Subjects were randomly placed into a chromium, placebo, or control group. All subjects were instructed to maintain daily activities. Analysis of variance revealed no significant differences in R values, body fat percentage, or lean body mass among the chromium, placebo, or control …

The Effects Of Specific Teacher Training Program Components On The Self-Assessment Skills Of Western Michigan University Physical Education Interns, Jerry G. Bergsma

Masters Theses

The effects of an undergraduate self-assessment training program on the accuracy of self-assessment during physical education intern teaching was the focus of this study. Fourteen subjects enrolled in Intern Teaching at Western Michigan University and a university in central Michigan were studied.

The groups were compared on accuracy of self-assessment in selected teacher behaviors, teacher feedback rates, and student behaviors. Subjects were video-taped during intern teaching sessions and asked to complete the Self-Assessment Form (Hawkins & Wiegand, 1989). Estimates of percent time spent engaged in selected behaviors and feedback rates were compared to actual times and rates collected from the …

A Comparison Of The Physical Activity, Body Composition And Self-Esteem Levels Of 5th And 6th Grade Students In Southwest Michigan, Rebevva C. Coady

Masters Theses

The problem of this study was to compare the physical activity levels, body fat percentage and self-esteem levels for children 1 O to 12 years of age. Subjects were 5th and 6th grade students who attended Schoolcraft or Lawton Middleschools in Southwest Michigan. The instruments used for this study consisted of the Lohman 2-site skinfold test, the Harter "What I am Like" self-esteem questionnaire, and a physical activity checklist. Subjects were grouped according to body fat percentage and physical activity level. Significant differences were found for males body fat groups for 4 of the 6 subscales of self-esteem: (1) . …

A Validation Of Target Heartrate Formulas Used In Swimming, Tasha Kay Litwinski

Masters Theses

The purpose of this study was to explore whether procedures used to establish target heart rates (THRs) for running are applicable to front crawl swimming. Eight male and 22 female fitness swimmers from Western Michigan University participated in this study. Their exercise durations under three experimental conditions were compared. The conditions were: (a) Condition 1, a treadmill run at an intensity equal to a THR of 85% of heart rate reserve (HRR); (b) Condition 2, a front crawl swim at an intensity equal to 85% of HRR; and (c) Condition 3, a front crawl swim at an intensity equal to …
