The Effect of Some Kinematic Variables on the Accuracy of the Overwhelming Transmission in Ground Tennis

Abstract

The aim of the study was to identify the impact of certain kinematic variables on the accuracy of the overwhelming transmission in ground tennis. The study used the descriptive correlative approach. The sample of the study consisted of (10) players from the national ground tennis team. The Kinematic variables including (elbow angle, wrist angle, shoulder angle, ball velocity, trunk tilt angle, knee angle, the kicking angle) were used. The researchers used one digital camera (Nikon) with a speed of (50) images / sec. The results of the study showed that all the kinematic variables applied on the sample of the study were statistically siginificant at (α≤0.05) associated with the accuracy of the overwhelming transmission. The results as well showed that there is a sequence in the spinning transmission in a harmonic way: from the bottom of the body to the moment of kicking the ball, which positively impacted the velocity of the ball, and in turn, the control over the accuracy and the direction of the ball became greater.
