The Effect of the Elastic Knee Support on Mechanical Variables of Some Physical Abilities for Basketball Players

Abstract

This study aimed to identify the effect of the Elastic Knee Support on mechanical variables of some physical abilities of basketball players. The sample of the study consisted of (3) basketball players who were chosen by the intentional method. The player was filmed doing a) vertical jump, broad jump , 10 meters sprint) with the elastic knee brace on the knee and given 3 attempts without the elastic knee brace on the knee. A Samsung camera, with a speed of (50) images per second, was installed on a multi-height tripod and on a flat ground. It was placed on the side level, 5 meters from the jumping area, and the height of the camera from the ground was (75 cm).The results of the study showed that the use of a flexible knee brace on the knee has a simple and non-statistically significant effect in reducing the average sprint speed of 10 meters and the variables related to the length and frequency of the step. And has a simple and non-significant effect in reducing the take-up speed, vertical distance, power and work during the performance of the vertical jump. And that the use of a flexible knee brace on the knee has a simple effect and is not statistically significant in reducing the speed of ascent, the ability and the horizontal distance during the horizontal jump. The researcher recommended the use of Elastic Knee Support in order to protect the knee from injury while maintaining the range of motion of the joint and the effectiveness of the work of the muscles working on the joint during running, vertical and broad jumping.
