Effect of Exercises Using a Pressing Tool on Some Biochemical and Skilled Variables of Tennis Players

This study aims to identify the effect of exercises using a pressing tool for the arms on some biochemical and skilled variables for tennis players. An experimental design was used to guide this study. The study included a purposive sample of six players from Al‑Jaish Sport Club who practice tennis. These players were received the administered intervention. To ensure the subjects’ homogeneity and normal distribution, the researcher used the mean, standards deviation, and skewness for the filed survey. The researcher concluded that there were statistically significant, within normal limit increase in the white and red blood cells counts as they include all what lead to increase body toxins and waste‑products of harmful cells. The researcher recommends paying attention to the biochemical variables for the players throughout training in order to develop their physiological abilities.
