Influence of Isotonic and Isometric Strength Training on Selected Physical Fitness Variables among College Football Players


The purpose of the study was to find out the effect of isotonic and isometric training on selected physical fitness variables among college football players. To achieve this purpose of the study 30 men football players studying in the faculty of arts and science, Annamalai University, Chidamdaram were selected as subjects at random. Their age ranged between 18 to 24 years. The selected participants were randomly divided into three equal groups of 10 footballers (n=10 each), two experimental groups and one control group. The participants were made aware of the training programme. Group-I underwent isotonic strength training, Group-II underwent isometric strength training and Group – III was the control group as they were not taken part in any specific training throughout the 12 weeks of intervention period. The following variable namely speed, agility and muscular strength endurance was selected as criterion variable. The collected data were analyzed statistically through analysis of covariance (ANCOVA) to fund 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 0.05 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 exists among isotonic and isometric strength training groups and control group on physical variables. And also isotonic and isometric strength training group showed significant improvement on selected physical variables when compared to control group.
