Because of the skill tennis transmission is a fundamental skill begins with it the game and implements after each point reflected negatively on the level of performance and achievement and therefore the researchers felt to make a comparison between successful and failed transmissions. This study aimed to The differences between the values of some kenmatical variables of the successful and failed straights transmissions in the tennis and differences between the summit of the electrical activity of the muscles of the striking arm (deltoid muscle and the triceps muscle and brachial biceps muscle and flexor carpi radialis) of the successful and failed straights transmissions in tennis. Speed of ball was targeted and filmed so as the EMG for activated muscles was recorded during Tennis transmissions. Current study put much of conclusions like; The high electrical activity of the deltoid muscle had an effect clearly in the speed of lifting movement of the upper arm to the top in the striking arm as was significant and in favor of the successful attempts.The high electrical activity of the flexor carpi radialis muscle has an effect clearly in the installation of the wrist at the moment of the collision between the ball and the racket as it was of significance and in favor of the successful attempts.

For the purpose of comparison the researchers use the device (fitmate pro) by bruce test to define some physiological variables in the players bodies. The research includes two sample :the first sample includes the players of long the players of long distance that train Aerobic training and the second sample includes the players of football that train anaerobic training related to the Respiratory system (,HR,RF,VO2max,EE). This research is carried out the physiological tests in the special laboratory of physical college Education /Diyala University. The research use the descriptive method with comparative style to fit the nature of the research .samples are divided according to the used energy system .The first sample includes a group of long distances which represents airy-system and the second one includes a group of team sports (football, handball and basketball) which represents non-airy system .After the u

Training according to the momentary plucks the absolute angles to the working body parts jumpers horizontal and vertical jumps with Athletics taking place have in raising a modern training trends which turn out researchers to apply empirically since the moment the upgrading is one of the most important stages in all competitions jump and jump and to prepare training plucks according to absolute angles of body parts moving when upgrading to these events and to identify the effect of these exercises in developing real-time and instantaneous torque force to working muscles as q pay and performance when upgrading. Applied research on a number of horizontal and vertical jumps Iraqi youth and measured instantaneous horizontal and vertical ampules their reliability as well as traffic, by device (Dina foot) and measuring the efficiency of real-time ampules according to the ratio of instantaneous torque and linear, as well as measure performance according to the ratio between flying angle and mechanical energy, a positive development emerged in the instantaneous ampules stability and movement as well as the development of efficient real-time ampules and performance.

The physical abilities of volleyball players consider the basic foundation upon which depend the applicant teams, so the game of volleyball has it's the basic principles through which the best method in training is used. The use of resistors in training as rubber ropes or aqueous medium and sand as well as free weights has helped to develop physical abilities which reflected positively on the level of technical performance of all the technical skills of the game , The performance of these exercises by using tools make it more difficult in order to raise the efficiency of the player The use of the smooth arena is one of the new methods to train players in general and players of the pivot in particular, this early way increased directly the physical abilities of the main game as force, speed and endurance and skills performance and the level of performance of the skills as the bulwark and defense of the court , as rising level of achievement quickly during the use of new exercises did not get used by the athlete. The importance of the current research is to identify the impact of the smooth areas to develop the side motor speed of the pivot players of Iraq team players and some defensive skills as well as the impact of the special exercises and that helped a sample search on the implementation of the tactical and skilled duties for the purpose of access to the high level of achievement.
