Abstract

The forehand clear strokes are among the most common strokes in badminton which account for 14~16% of the total overhead stroke of the players The adoption of players today on biomechanics In analyzing, clarifying, explaining and interpreting the results Then give the necessary recommendations especially for the Badminton He will develop them by developing different techniques, As well as the technical of forehand clear By knowing the mechanical laws that govern them, As well as knowing the accuracy of the motion path And the relationship between descriptive variants of jump technical level and achieve its goal. The aim of the present study was to determine the relationship of the biomechanical variables to forehand clear skill performance of wheelchair para-badminton players Descriptive survey method was used. The study subjects were from the Egyptian wheelchair para- badminton high level players. Players performance by Three-dimensional motion analysis of biomechanical variables. The main result was, the most important biomechanical variables affecting the speed of the shuttle Release velocity for the front clearance stroke skill at the moment the racket leaves the side of the chair is the increase in Resultant acceleration, Resultant force of all centers of gravity of the racket-bearing arm with the increase of the racket's acceleration of the wheelchairs para-badminton players. The researchers recommended that the need to direct training loads during the development of training programs according to the results of this research and to develop it of wheelchair para-badminton players.
