The relationship of kinetic balance and static balance to some biokinematic variables in the skill of the forehand and backhand in tennis

Abstract

Background: Biomechnology has been interested in multiple and complex mathematical movements and has begun to evolve in the performance of movements through the evolution of analysis, illustration, correction, study of motor minutes and recognition of the degree of relationship between biocynamic variables when performing any movement and the relationship of these variables to balance whether constant or moving. Groundstrokes are the most commonly used, as they constitute a very high percentage of tennis and are characterized by their defensive and offensive use. Objectives: Recognize the values of certain biokinamatic variables for front-strike skill. Recognize the level of motor balance and constant balance of female ground tennis players. Find the relationship between motor balance and constant balance with some biokinamatic variables. Conclusions: The angle of torso inclination in predisposition mode was positively associated with motor balance. The angles of the arm, especially the angle of the attachment, appeared to influence the balance of the motor body and demonstrated this through the association between them. Recommendations: Emphasize the development of moving balance and constant balance to perform forward strike skill. Emphasize the optimal angle of the trunk tilt during the execution of the forehand skill.
