Study on Technique Effectiveness of Antagonistic Sports Event

This paper discusses classic technique effectiveness,balance point and formula,and further proposes that the balance points of the technique effectiveness formula should be adjusted according to the attributes of athletes' game actions(offense,defense,control and stalemate,etc.)and constructs technique effectiveness formulas for the different balancing points between 0.4and 0.65.On this basis,taking table tennis as example,this paper chooses the average scoring rate of each game action(the first/third stroke,second/fourth stroke and after the fourth stroke)of elite players as the foundation for determining the technique effectiveness evaluation formula and calculates the value of their respective technical effectiveness.The findings show that the technique effectiveness values of different game actions are very close at P70,P50 and P30.In this way,the evaluation model and the comparison between various kinds of game action are simplified.At the same time,the individual and comprehensive case analysis shows that it is feasible to apply the technique effectiveness evaluation to training and competition practice.
