With the methods of 1iterature research and logical analysis,this paper made study on the temporal and spatial characteristics of vacated height of action sets and influence factors,discussed the training significance of vacated height of action sets by space-time synergy theory.The results show that vacated height training is important method to adapt to new rules;there are a lot of time and space factors,such as horizontal and vertical displacement,the time of pressing net and jumping,flight time.The main factors affecting vacated height are initial velocity,best moment of kicking stretch,body posture of touch net and the power quality of arms and legs.In order to adapt to the new rules,we should focus to train the vertical jump technique,coordination between pressing net and swing arm,connection technology and choosing a good point of touch or off the net.
