This paper expounds the principle of volleyball fitness methods from the aspects of characteristics and classification, aiming at opening up new ideas for promoting the development of volleyball from the field of creation and design of fitness methods.
However, only scientific and reasonable fitness methods can have fitness value. If the fitness method is unscientific and unreasonable, it will be counterproductive. Fitness value is the most important index to evaluate the adaptation method.

Beach volleyball was officially included in the Olympic Games in Atlanta from 65438 to 0996. Among the 28 Olympic events, volleyball occupies two events, namely volleyball and beach volleyball. It can be seen that volleyball is very popular and valued internationally, and the position of competitive volleyball in China is obvious to all, especially the China women's volleyball team, which won the championship in Athens Olympic Games in 2004 from the past "five consecutive championships". Such excellent results can not be separated from China's Olympic strategy of winning glory for our country. The popularity of volleyball in China is far less than that of basketball and football, and the situation of volleyball in primary and secondary schools, universities and rural areas is very poor. Such a serious problem must have its deep-seated reasons.
1, the measures taken by the national authorities to promote the development of volleyball are unfavorable;
2. The goal of competitive volleyball in China should not only stay in the Olympic strategy of winning glory for our country.
3. Personal understanding of the fitness value of volleyball is insufficient.
4. Many people only know competitive volleyball, but not leisure volleyball.
So the purpose of writing this article is to fully tap the fitness value of volleyball.
Let more people realize their participation in volleyball.
The value of sports lies in improving health, and it also plays a certain role in promoting the development and popularization of volleyball in China.
1. The fitness value of volleyball
1. 1 Good effects of volleyball on physiology.
Volleyball is a sport in which people who participate in sports hit each other in the air with any part of their bodies to keep the ball from landing. It can be done with or without a net. As a fitness activity, many people play a ball in a relatively small venue, and everyone's range of activities is not large. It can be seen that the load intensity of mass fitness volleyball is relatively small, and it is the characteristics of relatively small load intensity, strong safety and strong mass that attract more and more exercisers to join this ranks.
From the physiological point of view and the characteristics of volleyball itself,
Volleyball has a great influence on human physiology.
The following good effects:
1. 1. 1 improve energy metabolism and cardiopulmonary function.
The research results of volleyball at home and abroad prove that volleyball is a combination of aerobic energy supply and anaerobic energy supply. Domestic research also shows that anaerobic energy supply accounts for about 20%-40%, aerobic energy supply accounts for about 60%-80%, and aerobic energy supply is dominant. The results also show that volleyball is a sport of non-lactic acid energy supply system. Regular participation in volleyball can improve the level of aerobic metabolism, develop cardiovascular endurance, delay the aging process of cardiovascular system, increase cardiac output and enhance the function of oxygen transport system. People who often participate in volleyball can also increase their breathing strength and endurance, improve lung ventilation, and reduce their breathing frequency by about 10 times when they are quiet. Old people often participate in soft volleyball or balloon volleyball, which can delay the aging process of respiratory function.
1. 1.2 Improve the function of sensory organs.
In volleyball, all kinds of hitting methods, whether volleyball match or volleyball match, must be hitting the ball in the air, catching the ball of one's partner, especially catching the ball that the other side has touched the net. Even if you hit the ball over the net, you must throw the ball into the air before hitting the ball. So people who participate in volleyball gain a sense of time and space.
Training and improvement are incomparable to other ball games.
. Mainly manifested in: when hitting the ball, the player's sense of touch, pressure and proprioception of muscles and tendons will reflect the shape, weight, elasticity, size of the incoming ball and the strength of hitting the ball. So people who often play volleyball can improve their muscle proprioception.
1. 1.3 improve the ability to judge and control the predetermined goals.
