Abstract
The purpose of this investigation was to determine the effects of two speeds of isokinetic training on muscular strength, power and endurance on college females.
The study involved thirty college females. Twenty of the subjects who served in the experimental groups were randomly assigned to one of two groups: fast speed or slow speed group. This was done after matching based on the pretest strength measure. Ten subjects who served as the control group were from a bowling class This investigation was conducted for seven weeks with a training frequency of three days per week. The experimental treatment was isokinetic training for right and left knee extensions. There were three sets of repetitions; each set lasted twenty seconds with a thirty second rest period between each set. The dependent variables measured were strength, Power I, Power II and muscular endurance for the right and left knee extension.
Analysis of variance was used to determine differences between the groups on pretest measures. A comparison of the pretest and posttest means was made to determine differences resulting from training. Analysis of covariance was used for the posttest measures with pretest measures as covariates for the eight dependent variables.
Results of statistical analysis indicated that no significant differences existed on the pretest treasures between the three groups in the eight variables with the exception of Power I for the right knee and endurance measure for the left knee extension. Posttest analysis revealed significant differences in all the eight dependent variables between the experimental groups and the control group. Also, significant differences existed between the fast speed and the slow speed groups for six of the eight variables. There were no significant differences on the strength measures between the experimental groups.
The isokinetic training method was found to be effective in developing strength, power and muscular endurance. Also, the isokinetic fast speed was found to be a more effective way of bringing about power and muscular endurance development.
