The purpose of the study was to investigate and Isometric exercise on cricket playing ability. The criterion measure selected for cricket playing abilities were batting, bowling and fielding performances. The subjects were 90 male school and college cricket player of Jammu. The age of the player ranged from 16 to 22 years. The analysis of covariance for batting, bowling and fielding skills indicated the resultant F-ratio in the case of pre-test means and post-test means were significant. The difference between the adjusted final means for groups was however, significant. The critical difference for adjusted means revealed that the mean gain made by all experimental groups showed statistically significant difference between experimental group and control group in bating and bowling performance. In fielding performance the critical differences for adjusted means showed that the mean gain made by experimental groups showed statistically significant difference among experimental group and control group.
