The most important conclusions are: 1 - Harmonic exercises are important and necessary in the development of some types of balance on the device balance balance in the technical consensus.2 - Balance of the qualities necessary to achieve the performance of the skill on the balance device Baljmnstk technical.The researcher recommended: 1 - the adoption of harmonized exercises for their importance in the development of some types of balance on the device balance balance Baljmnastic technical. 2 - the need to emphasize the balance because it is necessary qualities to achieve the performance of the skill on the device balance balance technical Gemnastic.

Volleyball is an important and fundamental factor. It is the key to getting points in the case of perfecting its performance. It is also one of the most important direct attack strikes used by the player during the game, which may put the players of the opposing team in a weak defensive position, the stronger the speed and sophisticated in accuracy In the right place, the task of the opposing team was the most difficult. The current study is important in the kinetic analysis of side-by-side. Through these variables, we seek to obtain biomechanical specifications, which we can rely on in side-by-side training. And to recognize the importance of this type of transmission and then raise the level of technical performance and high technology of the players
The research aims to
Identification of some of the kinetic indicators of the lateral side of the volleyball -
Identify the accuracy and velocity of the ball for the lateral side of the volleyball -
-Finding the relationship between some kinetic variables and the speed of the ball and accuracy in the lateral side
Research Methodology: The researcher used the descriptive approach to its suitability and the nature of the research
The study included a number of players of the team of Mosul University in volleyball, (7) players, and was used the following statistical treatments (mean, standard deviation, simple correlation coefficient, difference coefficient )
Key conclusions :
1-There is a negative correlation between the two variables (the real palm path of the main stage, the speed of the palm path of the main stage) and the accuracy of the transmission
2-the existence of a significant correlation between the variable angle of the ball and the accuracy of the transmitter
3-There is a positive correlation between the positive distance of the exit of the ball and the speed of the ball

The importance of the research to improve the volleyball players by giving indications of some important chemical variables resulting from the impact of training and competitions on the body of the player and how to overcome them and make it able to communicate with play and training.
The aim of the research was to identify the effect of the competition on certain chemical parameters of volleyball players.
The sample included volleyball players for the University of Diyala for the academic year (2018-2019)
The most important conclusions were:
1- The level of concentration of calcium, magnesium and iron in the serum is less immediately after the
game than in volleyball players because of permeability of membranes.
2-The level of concentration of phosphorus in the serum increases after the game is performed directly than before by the volleyball players because of the composition of the acid compounds and works to break the bio-energy vehicles.
It was recommended that:
1-The indicators obtained are necessary to assess the status of players and knowledge of the impact of the game on the variables of chemistry and special variables under study for the purpose of attention to nutritional supplements and training.
2-the need to pay attention to study the impact of the game in the other indicators of the chemical connotations of volleyball players.

The importance of research in the development of the speed of performance of the use of rubber cords, which has a large role in increasing the burden on the working muscles, the problem of research was manifested by the researchers observed the obvious weakness in the speed of the player during the attack stage of payment and because of not taking the right position for a moment The study aimed at To the number of exercises speed performance of the use of rubber cords for the skill of beating the high volley ball and to recognize the effect of speed training performance of the use of rubber cords in the characteristics of the curve (strength - time) and some biochemical variables of the overwhelming beating of the center (2) And the researchers used the experimental method in the design of one group. The research sample was determined by the deliberate method, namely, the players of Al Gharraf Club in the Premier League (B) (8) weeks of training (3) training units per week. The most important conclusions are the emergence of a clear development in the level of technical performance of the high crushing skill due to the development of the instantaneous force using rubber ropes. The recommendations were the most important Due to the speed of your workouts performance with rubber cords, especially the muscles working on the joints of the hips, knees and ankles as well as working on the muscles on the joints of the shoulders, elbows and wrists.

The educators have agreed that education is a profession that should be enjoyed by those who are employed, Special efficiency is distinguished him from other members of the other professions . The way to provide this sufficient is to prepare him the appropriate preparation in educational institutions so that this preparation produces qualified teachers aware of the importance of their profession, Which ensures the ability to perform the duties of this profession in the best manner and will be in the future a reason for achieving the teacher's goals rather than being disabled to achieve these goals. The importance of this study is the development of a standard or criterion for measuring the efficiency of teachers of physical education and measuring their success or failure in teaching physical education. The research problem emerged through the researchers' feeling that there are deficiencies and weaknesses in the ability of some teachers of physical education to prepare students and provide information and fill the needs of this material and its requirements to achieve its educational, physical, psychological, health and other goals. The goal of the research is to: Identify the teaching competencies of teachers of physical education and identify the level of performance of teachers of physical education during the lesson. And finding the relationship and determining the levels of performance evaluation for teachers of physical education. The researchers assume that there are differences of statistical significance in teaching competencies of teacher of physical education ,. The researchers used the descriptive approach in the method of survey and correlation studies. The research society included teachers of physical education for the academic year (2017- 2018).and their number 409 teachers of female and male.The sample consisted of (82) teachers from the schools of the center of Al-Hamzah and It's sub_rigions(Al-Sudair and Al-Shanafiyah). They were selected by simple random way (lot) 20%) of the research community The results of the research showed that teachers of physical education possess teaching competencies below the level of ambition. The level of performance is not acceptable and without the level of ambition. The teaching competencies have a significant impact on the level of performance, and through the evaluation form it was found that the best level of performance was within the managerial and organizational axis. The researchers recommended the development of staff in educational supervision and specialists and the holding of courses for the rehabilitation, development and training of teachers on the modern teaching methods and the establishment of the typical lessons The preparation of squares and playgrounds and laboratories to apply the practical material in the curriculum to develop and expand the lesson soils And increase the number of lessons that help to give students more experience.
