Contribution Percentages of some Kinematical Variables of the Main Position in the Skills Performance Level of the Two-handed backhand Stroke for Tennis Players

Abstract

The study aimed to recognize the contribution  rates of  some Kinematical variables of   main position in the Skillful performance level of the two-handed  backhand stroke for tennis players, The researchers assumed that there are a contribution ratios of  some Kinematical variables of main position in the skillful performance level of the two-handed backhand stroke for tennis players, research sample was consisted of (8) senior players in Ninevah province, the researchers concluded that the Kinematical variables (shoulders angle, height of the BMC) in the main position had a significant contribution in the skillful performance level of the two-handed backhand stroke, the researchers recommend to emphasis on the tennis coaches to adopt mechanical variables, which showed a significant contribution to its role in the development  the two-handed backhand stroke skill and to Increase the interest in the Kinematical variables that  produced by the study.
