The purpose of the study was to find out the effect of maximal power training on leg strength of university men players. To achieve this purpose of the study, thirty men players from different games in the Department of Physical Education and Sports Sciences, Various University, Pudukkottai District, Tamil Nadu, India were selected as subjects at random. The selected subjects were divided into two equal groups of fifteen subjects each, such as maximal power running group and control group. The group I underwent maximal power training programme for three days per week for twelve weeks. And Group II acted as control group who did not participate any special training programmes apart from their regular physical education activities as per their curriculum. The following variable namely leg strength was selected as criterion variable and it was measured by using leg dynamometer. All the subjects of two groups were tested on selected criterion variable at prior to and immediately after the training programme. The analysis of covariance was used to analyse the significant difference, if any between the groups. The level of significance to test the ‘F’ ratio obtained by the analysis of covariance was tested at .05 level of confidence, which was considered as an appropriate. The results of the study revealed that there was a significant difference between maximal power training group and control group on leg strength. And also it was found that there was a significant improvement on leg length due to maximal power training.
