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.

Book The Effects of Limited Range of Motion Isokinetic Knee Extensor Training on Isometric Strength Development Inside and Outside of the Trained Range of Motion

Download or read book The Effects of Limited Range of Motion Isokinetic Knee Extensor Training on Isometric Strength Development Inside and Outside of the Trained Range of Motion written by Jennifer L. Donner and published by . This book was released on 1992 with total page 68 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: The purpose of this study was to determine the effects of limited range of motion (ROM) isokinetic knee extensor exercise on isometric strength development inside and outside the trained ROM. Four male and 18 female volunteers between the ages of 20 and 48 years were randomly assigned to one of two groups. The experimental group trained the knee extensors isokinetically on the KINCOM from 45 to 0 degrees of knee flexion three times a week for five weeks. The control group did not train. Both groups were pretested and posttested on the KINCOM for isometric knee extensor peak torque at 15, 25, 35, 55, 65 and 75 degrees of knee flexion. One half of the subjects in each group was tested at each angle in ascending order, while the other half was tested in descending order. The two orders of testing were randomly assigned and balanced over subjects with a matching procedure. Repeated-measures ANOVA with one between groups factor was used to determine if significant differences existed between the groups. Tukey's Honestly Significantly Different test was used to make pairwise comparisons between group means at each angle. Upon statistical analysis it was determined that no significant differences existed between the groups at each angle of measurement except at 75 degrees of knee flexion (p
