Abstract
The current study's goal was to look into how isotonic and isometric training affected explosive strength. 60 male students from the Department of Physical Education at C.D.L.U. Sirsa (Haryana) were chosen for the study in order to accomplish this goal. The chosen subjects, such as physical exertion and isometric coaching, and management cluster, were separated into three equal teams of twenty subjects each. First Group undertook an isotonic training programme, Group II underwent isometric coaching for twelve weeks on three days per week, and Group III served as the management cluster, participating in only their usual educational activities in accordance with their curriculum. Leg strength was chosen as the next criterion variable, and it was assessed using the leg raise technique with dynamometer. The study's aim was to investigate the effects of isometric and isotonic training on leg strength. On a specific criterion variable, all the topics for the three teams were examined during, before, and right after the coaching programme. The analysis of variance was used to determine whether there were any significant differences between the teams. At a confidence level of 0.05, the degree of significance was examined in regard to the 'F' magnitude connection discovered by the analysis of variance. According to the study's findings, there was a substantial difference in leg strength between the coaching cluster and management cluster in isotonic and isometric exercises. Additionally, it was discovered that isometric and isotonic exercises significantly improved leg strength.
