The research aims to study the muscle balance of some tennis skills in terms of the electrical activity of the muscles of the upper limb of wheelchair players.

The two researchers used the descriptive approach in the case study method in order to suit the nature and purpose of the study.

In Alexandria, during the 2019 training course, the study was conducted in the Biomechanics Laboratory of the Faculty of Physical Education for Boys, Alexandria University.

A relationship was found between the electrical activity of the muscles of the upper extremity, the balance error, the angle of the racket, the height of the ball and the speed of the ball launch for some tennis skills for wheelchair players - the variation of the differences between some tennis skills of the wheelchair players in the average electrical activity of the muscles of the upper extremity, the balance error, the angle of the racket, the height of the ball and the speed The ball is launched
