Influence of High Intensity Interval and Low Intensity Interval Trainings on Selected Motor Fitness Components

Abstract

The purpose of the study was to find out the effects of high intensity interval training and Low intensity interval training on selected motor fitness components namely speed and agility. To achieve this purpose of the study, forty five men students studying Annamalai University, Annamalai Nagar, Chidambaram, Tamil Nadu and India were selected as subjects at random. Their age ranged between 18 to 24 years. The selected subjects were divided into three equal groups of fifteen each namely high intensity interval training group, Low intensity interval training group and control group. The experimental group I underwent high intensity interval training and group II underwent Low intensity interval training for three days per week for twelve weeks whereas the control group maintained their daily routine activities and no special training was given to them. The following motor fitness components namely speed and agility were selected as criterion variables. The subjects of the three groups were tested on selected motor fitness components namely speed and agility using standardized tests namely 50 mts run and shuttle run at prior and immediately after the training period. The collected data were analyzed statistically through analysis of covariance (ANCOVA) to find out the significant difference, if any among the groups. Whenever the obtained “F” ratio was found to be significant, the Scheffe’s test was applied as post hoc test to find out the paired mean difference, if any. The .05 level of confidence was fixed to test the level of significance which was considered as an appropriate. The results of the study showed that there was a significant difference exist among high intensity interval training group, Low intensity interval training group and control group on selected motor fitness components namely speed and agility. And also high intensity interval training group and Low intensity interval training group showed significant improvement on speed and agility when compared to control group.
