The research aims to identify the effect of circular strength training on some special physical variables and the level of skill performance of squash players.
Research hypotheses
1- There are statistically significant differences between the mean of pre and post measurements in the level of some special physical variables and the level of skill performance of squash players experimental research group.
2- There are statistically significant differences between the mean of the pre and post measurements in the level of some special physical variables and the level of skill  performance of the squash players.
3- There are statistically significant differences between the two mean measurements in the experimental and control groups in the level of some special physical variables and the skill performance level of squash players for the benefit of the experimental research group.
