Biomechanical Statistical Model for the Accuracy of the Forehand Smash Stroke in Higher Levels of Table Tennis

Abstract

The research aims to improve the accuracy of the forehand smash stroke in higher levels of table tennis through: Designing and standardizing the test of the accuracy of the forehand smash stroke in higher levels of table tennis, Recognizing the relationship between some of the biomechanical indicators and the degree of accuracy at the moment of hitting the ball, Extracting a biomechanical statistical model in light of predicting the equation of the accuracy of the smash stroke at the moment of hitting the ball. The sample was selected by the Propulsive Sampling Technique. 13 table tennis players from Smouha and Alexandria Club Sporting were selected. The players were divided into 10 players to control the test and 3 players to conduct the video record and the biomechanical analysis. 3 excellent players in the forehand smash stroke were selected to record their performance by a video camera. The researcher reached the following conclusions: (A) the proposed test is used to measure the accuracy of the smash stroke. (B) The biomechanical statistical model that concluded according to the degree of correlation: The accuracy degree of performance = Constant + Stepwise Regression of variable × average resultant of variable
