    Abstract

    Central stability is the ability to control the position and movement of the trunk on the pelvis, which allows the control and transmission of force and movement to the extremities during sports activities, which muscle contraction can maintain this stability to increase Improving central stability can be effective in preventing injuries, increasing strength and balance despite improving sports performance. This research has investigated the relationship between central stability and sports performance of volleyball players. For this purpose, 30 volleyball athletes of Damghan city with average age, weight and height voluntarily participated in this research. Tests related to central stability (McGill protocol) including: endurance of anterior, posterior and lateral muscles of the trunk, medicine ball throwing tests and sitting up, and performance related tests including vertical jump and 4.9 meters and 20 meters sprint were performed. Pearson's statistical test was used with a significance level of 0.05. According to the results of the relationship between central stability and functional tests, a weak to moderate relationship was seen. Although we found a weak significant relationship between central stability tests and performance tests (except for running), we cannot comment with certainty about this relationship and the effect of central stability on sports performance, and we need to conduct more research on this issue.

    Research overview

    1-1 Introduction

    Movement is one of the characteristics of human life. The need for movement and activity throughout his life has always been associated with gaining experiences and discovering new methods. One of the most important factors in the process of championship sports and the development of young athletes who are prone to optimal use of applied research in sports is one of the most important factors. Sports fields and of course the champions of sports fields have their own physical and physiological characteristics. The increasing progress of sports science and new findings and their application in expanding and improving the physiological and technical condition of athletes has led to the amazing progress of records and the performance of sports movements. (Hosseini 1381)

    A careful observation and examination based on scientific principles in various factors affecting this high physical and mental efficiency has led the practitioners of sports science to give priority to the principle of research in the fields related to sports and to put a lot of emphasis on the applicability of research issues. Among the issues related to championship sports, the issue of physical and physiological preparation in making more use of the movement abilities and skills of athletes in various disciplines was raised. The progress of sports science in recent years has been very impressive, and physical preparation, as an important part of these advances, has not been far from change and development. Doing special exercises is particularly important to achieve optimal preparation in sports fields (Haqighi, 2017)

    Supporting national teams is one of the missing links in our sport. Sports talent scouting is a process by which young people are guided towards sports that have a higher chance of success based on certain tests. (Chobineh Siros)

    Achieving elite status in sports from the point of view of talent search is not only limited to the discovery of talented people at a young age, but it is also very important to guide the continuous control and evaluation of talented people so that the talent search process can be fruitful (Rajabi, Hamidah. 2014)

    The effectiveness of the talent search process depends on the continuity and integration of the three rings. And the interconnected stage of identifying effective people is guiding effective people, supporting talented people (Yousfi, Bahram Guderzi Mahmoud 1382).Bahram Gudarzi Mahmoud 1382)

    According to the distinction between talent search and talent development, it can be said that talent search is the first step for talent development (Karakhanlu Reza. Afzalpour Ismail 1386)

    The appropriate talent search system for sports is often considered as an important factor in the sports success of countries at the level of important international competitions. that the orientation and final selection of sports in athletes is a multi-dimensional and complex process. On the other hand, today we are witnessing the fact that the sports managers of our country consider the sports success or failure of athletes at the international level to be directly related to the scientific and timely selection of sports talent.

    Volleyball in 1895 according to the solar year 1274 by William J. Morgan in Holic State It was invented in Massachusetts, America. In the beginning, this sport was named Mintonet, then it was changed to volleyball.

    Volleyball is a team sport between two teams on a rectangular field with equal lines and a net with a width of 1 meter, each team is allowed to use 6 players. they change To exchange the ball to the other side of the net, each team is only allowed to hit three times, and when the ball hits the opponent's field or due to a team's mistake, one point is given to the opposing team. Physiologically, the final reflection of each sport depends on the potential characteristics of that specific sport, therefore, in each sport, awareness of the biological science of sports and the description of the characteristics of physical activities for the physiological needs of the body are of particular importance. These explosive and fast movements are performed with maximum strength and muscle power in a fraction of a second, and their number is very high in a rally round.

    Given that all players are tall in volleyball. Explosive power and jump height are effective in their success rate on the net. Therefore, strengthening jumping is an integral part of bodybuilding programs in volleyball (Rastegar 1384)

    The issue to be considered is that the muscles of the central area of ??the body, which is the interface between the upper and lower limbs, can affect the performance of these athletes, and by strengthening the central area and increasing physical fitness, they can improve their performance.

    In volleyball, speed and strength are important factors in achieving success. On the other hand, having balance is one of the important aspects of physical fitness that athletes benefit from to improve their performances, so that few sports can be named in which balance does not play a role.

    Central stability. The ability of the lumbar-pelvic-thigh complex is to prevent instability of the spine and return to balance after disturbance. It has been shown that before performing movements in the organs, the muscles of the central region are activated. The central stability can be assumed to be like a box where the abdominal muscles are located in the front, the parspinal and gluteal muscles are located in the back, the diaphragm muscle is located in the roof, and the thigh muscles are located in the bottom. Central training is a key for effective biomechanical function of organs, which works by increasing force production and reducing joint loads in all types of activities from running to swinging. It has not been determined what anatomical and physiological elements are involved in creating central stability. For this reason, the physical evaluations of central stability are also different. The muscles of the central region act as a bridge between the upper and lower limbs. And in this way, power is produced from the central area and transferred to the organs. Initially, stability requires maintaining the neutral position of the vertebral column, but it must also exist in situations where the spine is out of neutral position.
