Time passes and sports coaches compete in discovering new training methods, which raise the efficiency of players physically and technically to meet the requirements of sports activity and exercise to reach the ideal in performance.
The efforts of researchers and workers in sports training in all sports activities are multiplied in order to improve and improve performance in the type of sports activity practiced in order to raise the level of achievement in the activity based on all scientific and technological methods in the process of education and training.
In recent years, the science of sports training has taken great strides forward. The efforts of scientists in various fields of science related to sport have multiplied in general, and the most important efforts of specialized and interested scientists in advancing the level of sport is to find the best ways and means to develop the physical and athletic level of the athlete.
That the sport of volleyball in its current form is one of the high-end sports practiced in international and Olympic meetings and attracts many audiences because it is one of the ball games characterized by the characteristics of its advantage from the rest of the other group games, not related to a certain time as well how to deal with the ball where sometimes found concrete and multiplied , In addition to the wonderful mix of technical and aesthetic performance that is shown by the movement of players in the stadium as well as the high level of performance skill and plan by the players and we can not miss the changing positions and exciting, all during the practice practice , All features that put the game in the ranks of the other Olympic Games (23: 90)
Volleyball is one of the most competitive sports activities in which the desire to show the spirit of excellence, victory and victory is reflected. It is based on sports training, its principles and various disciplines within the formation of the volleyball team, which require special skills and skills (25: 52). (18: 1)
That athletes, coaches and sports scientists are always looking for exercises aimed at improving performance, and that one of these recent trends in training is the training of functional strength
Ron Jones 2003 notes that functional strength training is one of the most recently used training forms in the sports field.
”Ijalal Ibrahim and Nadia Darwish 1994” show that the muscles working for strength training for the center or fair body area, which include the muscles of the abdomen, back and sides, which is the main physical and muscular center of the distribution of movement in the human body because if we passed a longitudinal line of the head of the two men, The center corresponds to the lines at the point in the middle of the body and the abdomen and the corresponding point is the back and sides, the evidence that if the player moves the arms or legs; it feels moving the muscles of the abdomen and back and sides and so the muscles of the center is the basis of good motor performance
The barrier is one of the most important skills in the defense of the stadium against various online attacks. It is a way to frustrate the opponent’s resolve by preventing his attackers from hitting the ball or absorbing it (defensive wall) Against the opposing team (the wall of offensive attack), and the formation of the wall of the repudiation of players is common in the matches of one player, while the formation of three players is a little use; because it increases the responsibility of the existing players (42: 137,139) The researcher believes that due to the nature of the performance of these skills, it requires special physical abilities so that the player can deal with the speed of the ball multiplied and rebound from the wall of the defense and defend the ball in and out Due to the variety of skill and tactical performance in volleyball, players have required a number of quick start-ups, as well as short-range sprinting, as in the case of gear, as well as jumping and hitting. Therefore, the volleyball player must be characterized by speed or fast power (Ability), It is important that the ability of muscles and strength of the muscles of the two men to perform volleyball skills such as high jump for the performance of offensive hitting skills and defensive and offensive repulsion also jump high during the overwhelming transmission , In addition to the length of performance and continuity in the stadium and the diversity of skills in the run of the game, but in one point all this leads to the importance of the player and the enjoyment of volleyball to be a component of power. The player can not master the basic skills of volleyball in the absence of special physical abilities, and muscle strength is one of the most important capabilities that contribute to mastering these skills, and this is evident in the contribution of the muscle strength component in the development of defense skills for the stadium, And in addition to the power-bearing component that is evident during the performance of the stadium and its duration for extended periods of time. Volleyball requires multiple motor models (jump, run, fly, drop, stab, dive, bounce) that allow the player to continue Performance inside the dump This requires players to demonstrate all the skills of the game, as well as moving from defense to attack and vice versa, as well as offensive formations from the front and rear area and trying to open loopholes in the wall. The opponent of the opposing team, and volleyball of the games in which the transfer of the course of strength from the parties through the center of the weight of the body and the central muscles and the use of that force in the completion of these models motor: which requires the player to have sufficient muscle strength of the muscles of the center even to A leaking of that power generated by the parties. And through the experience of the researcher as a player and coach noted that the inability of most players to achieve those models of mobility in the stadium repeatedly and with the same strength and efficiency in performance; which returned the researcher from his point of view to the weakness of the central muscles. In view of the tremendous development in the science of sports training and the development of methods and methods of training, a new form of muscle strength development, namely, functional strength training, has emerged as a complete integration between balance training and muscle strength training. During the development of the muscles of the center, which is the basis of movement within the human body, all sports movements will lack efficiency without integration with strong muscles of the center, as well as the exploitation of power generated by the parties and developed from the movement of one of the movements repeated and the same strength in performance; W to design a training program using functional exercises force for the development of some physical and skill variables for volleyball players. Objectives of the research: The aim of the research is to design a training program using functional strength training to identify the following: 1- The effect of using functional strength training in developing the level of some physical variables for volleyball players. 2- The effect of using functional strength training in developing the performance level of some skill variables for volleyball players. There are statistically significant differences between the average of the tribal and the remote measurements of the experimental group in the physical and skill variables under study and in the direction of post-measurement. • There are statistically significant differences between the average of the tribal and remote measures of the control group in the physical and skill variables in the research and in the direction of post-measurement • There are statistically significant differences between the mean of the two dimensions of the experimental group and the control in the physical and skill variables in the research and in the direction of the experimental group. Functional Strength Exercises: ”Multi-level, multi-level movements involving acceleration, stabilization and deceleration, with the aim of improving motor capacity, central force (mean mid-spine, and neuromuscular efficiency). (64) First: Methodology: In accordance with the nature of the research problem and to achieve its objectives and test for its hypotheses, the researcher followed the experimental method using experimental design of two groups, one experimental and the other experimental using tribal and remote measurement for both groups. - The sample: The researcher selected the same type of research by the intention of the team of the Arab Club of Kuwait under the age of 17 years and the strength of the sample (30) player was divided into two groups, one experimental and 15 (15) players and (15) players and registered in the Kuwaiti Volleyball Federation for the 2016/2017 season. The pilot study was conducted on a sample of 20 players from the Arab Club of Al-Arabi Club under 17 years from within the research community and outside the basic sample of the research
