Abstract
The object of this research is to recognize energy system involved in volleyball by emphasize on differences in different posts in super league games of Iran’s sport clubs. According to the games table, all 24 go and return games of one teams has been filming directly by researcher. In order to examine better, at first by expert programs, films were changed to usable format in analyze program, then the number and the type of gathered jumps has been gathered, examined and the analysis has been stored. Through one-way variance analysis, gathered information has been evaluated on meaningful level of (p<0.05). Along rally in all games, the mean time of activity and rest is (20±9, 6±4), respectively. The mean of jumps in setter post, middle blocker, hitter, opposite hitter are (66, 70, 62, 53), respectively. Also, the method of distribution of activity times for rallies during competitions shows that the most frequency is in 4, 5 seconds. Also, the mean activity time is equal to 6second and more than 90%of the all plays time is under 11seconds. Based on research findings, the most energy system in volleyball is of anaerobic and based on phosphagen system. Therefore, according to different performance requirement in which requires different Physiological, physical, skill characteristic, we should perform and program special exercise program according to individual differences of players.
