Biomechanical comparison between the hitting arm of the skill of serving with a face The front racket and the service face the back racket in squash

This research aims to identify the biomechanical differences of the striking arm of the skill of the high transmission against the front and back racket. The researcher used the descriptive method based on the technique of high-speed video analysis of the skill using Simi Motion, and the research sample included 5 players classified from the ten best players at the level of State of Kuwait under 19 years old.
The researcher used the SPSS statistical program, in which 10 attempts to serve with the front club and 10 attempts to serve against the front racket were processed.
The most important findings of the researcher was that the squash player takes advantage of the velocity of the right shoulder of the striking arm during the moment of collision, and that the velocity of the horizontal and vertical ball in the rear transmission is faster than the front transmission, and the most important recommendations were that the mechanical properties reached by the researcher can be determined through The effectiveness of the skillful performance of the rear service and the forward transmission of the squash players in addition to the interest in giving exercises to develop the force characteristic of speed for the two players alike. The speed of sending the ball, that the squash player takes advantage of the speed of the right shoulder of the hitting arm during the moment of collision, that the speed of the horizontal and vertical ball in the back service is faster than the forward service.
