The effect of biometric training on transmission speed and the development of physical performance in tennis

Research Objectives: The research aims to identify: 1- The effect of the ballometric exercises on the speed and accuracy of the transmission in tennis (for the sample in question). 2- The effect of the ballometric exercises on some of the capabilities affecting the physical performance of tennis (for the sample in question). Research Procedures, Research Methodology: The researcher used the experimental approach using pre and post measurement for two groups, one is experimental and the other is control, due to its suitability to the nature of the research. The research community and sample: The entire research community was chosen in the intentional way and they are (players and students of the third and fourth year majoring tennis training) in the Department of Sports Training and Movement Science at the Faculty of Physical Education Alexandria University for the academic year 2015/2016 and the number (30), the basic study was conducted on (20) Female students were randomly divided into two groups, one experimental (n = 10) and the other control (n = 10) students, all of them using the right hand, and no training programs were designed for them as in the current study before. While the survey was conducted on (10) Students, and Table (1), (2) and (3) show the homogeneity of the total sample E in the primary and primary variables before the experiment. Conclusions: 1- The proposed plyometric exercises had a positive effect on the speed and accuracy of transmission in tennis for the experimental group. 2- The proposed plyometric exercises led to a significant improvement in physical performance (the muscular ability of the arms and legs - agility - reaction speed - transition speed) in tennis for the experimental group. 3 - The proposed plyometric exercises contributed greatly to the high rates of improvement of all research variables of the experimental group compared to the control group 4 - The effect of the traditional program used among the members of the control group positively on the accuracy of transmission and some variables of physical performance in tennis.
