Download or read book The Effects of Isometric Exercise on Certain Anthropometric Measurements Muscular Endurance and Muscular Strength of College Women written by Janet Jackson Armstrong and published by . This book was released on 1963 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Thirty-three freshman women students, enrolled in the required physical education classes at the University of Alberta, were tested on weight; girth of the waist, hips, right thigh and right forearm; skinfold thickness of the abdomen, right rear thigh and right forearm; right quadriceps strength; right grip strength; and muscular endurance of the abdominal muscles as measured by the number of sit-ups performed in two minutes. The subjects acted as their own controls. For the six week control period, they were excused from participation in physical education classes. They were tested again at the end of this period. For the following six weeks of the experimental period, the subjects performed two different isometric exercises daily. Six six-second contractions of the muscles of the abdominal, gluteal and thigh regions were held maximally, with the subjects in an erect standing position. Each six-second contraction was alternated by two seconds of rest. One six-second contraction of the muscles of the right hand and forearm was held maximally, with the right hand supinated and clenched and the right elbow flexed at a ninety degree angle and held against the side of the body. At the end of the six week training period, the subjects were again tested on all eleven variables. The data from all three trials were subjected to analysis of variance. If the resulting F ratio for trial differences was found to be non-significant, the null hypothesis was not rejected. If the F ratio for trial differences was statistically significant, the null hypothesis was rejected and Duncan^s New Multiple Range Test was employed to determine between which means the statistically significant mean difference lay. Upon analysis of variance, it was found that no statistically significant mean changes had occurred in the measurements of weight; waist, hip and right forearm girth; rear thigh and forearm skinfolds; or right quadriceps strength. Following analysis of variance and Duncan 9 s New Multiple Range Test, it was found that there had been a mean increase in right thigh girth during the control period of 0.36 inches (statistically significant at the .01 level of confidence). Over the entire twelve weeks of the experiment, mean abdominal skinfold increased 0.99 millimetres (statistically significant at the ,05 level of confidence). During the six week period of isometric training, mean right grip strength increased 1.89 pounds, a change which was statistically significant at the ,05 level of confidence. Following this period, it was found that the mean number of sit-ups performed had increased 3»3s> indicating an improvement in abdominal muscular endurance that was statistically significant at the .01 level of confidence.

Book The Effect of Brief Isometric and Isotonic Exercise Programmes on the Development of Strength and Muscular Endurance

This book was released on 1963 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of the study was to investigate the effects of short bouts of maximal isotonic and isometric contractions on the development of strength and muscular endurance of the extensors of the knee. Subproblems investigated were crosstransfer, hypertrophy, and specificity of training. Sixty grade ten boys enrolled in a required physical education class at Bonnie Doon high school in the city of Edmonton served as subjects. After initially being measured for girth and fat, strength at angles of 115 degrees and 135 degrees of extension, and muscular endurance (holding time), the boys were randomly divided into three groups, each group containing twenty subjects. One group became the isotonic training group; a second group became the isometric training group; the third group became the control. The exercises were performed once daily, five days a week, for five weeks. The isometric exercise programme consisted of three six second maximal contractions. One contraction was made with the leg 90 degrees flexed, one at 135 degrees of extension, and one at 165 degrees of extension. The isotonic exercise programme consisted of lifting a maximal weight from the 90 degree flexed position to the 165 degrees extended position three times daily. Each bout required six seconds for the leg to be moved through the specified range. The leg was extended at a constant rate. Results were considered statistically significant at the .05 level of confidence. It was concluded that the isotonic exercise group increased significantly over the isometric group (F=6.26[subscript .05]), and both exercise groups increased significantly over the control group (F=26.95[subscript .01]), at the 135 degree angle, when measured for strength. Both exercise groups made a significant increase in strength over the control group (F=l8.91[subscript .01]) at the 115 degree angle. The muscular endurance, when measured by employing the same weight for both initial and final tests, increased significantly for the combined isotonic and isometric group scores of the trained leg (F=4.51[subscript .01]) when compared to the control. Cross-transfer of strength was statistically significant for both isotonic and isometric exercise groups at both the 115 degrees (.01 level) and 135 degrees (.01 level) angles. There was no evidence of cross-transfer of muscular endurance. No evidence was found to support either hypertrophy or specificity training.
