The effect of French variation training on some special physical Abilities and the performance level of the straight backhand stroke for squash juniors

The research aims to identify the effect of French variation training in developing some special physical abilities (special reactive agility, acceleration, movement speed of the legs, muscular ability of the legs), as well as the level (accuracy, strength, and speed) of the straight backhand strike for squash juniors.
The researcher used the experimental method, using the experimental design for one group using a pre- and post-measurement method, on a sample of (12) squash juniors at the El-Mahalla El-Kubra Municipal Club under 15 years of age, registered by the Egyptian Squash Federation. The researcher measured some special physical abilities - under research – And the skill performance of the level of accuracy, strength, speed of the straight backhand skill. The following statistical coefficients were used: arithmetic mean - standard deviation - torsion coefficient - correlation coefficient (t) - value (t) - percentage of improvement %
The most important conclusions:
1- The French variation training program, which was applied to the research sample, has a positive effect on the development of some special physical abilities (special reactive agility, acceleration, movement speed of the legs, muscular ability of the legs), - under research - for the junior squash players, the research sample.
2- The French variation training program, which was applied to the research sample, positively affects the level of accuracy, strength, and speed of performing the straight backhand skill - under research - for the junior squash players, the research sample.
