Study On The Index System And Method Of Power Quality Evaluation Of Male Tennis College Students In Physical Education Colleges

Tennis is a technology-oriented,strength quality for the assurance of the sport.Good strength quality can help tennis participants better grasp the technical movements。 However,in relevant researches,there are still some problems,such as unclear definition of strength quality index system and structure to be improved,in terms of how to monitor and evaluate the strength quality of tennis participants in tennis matches and training.Therefore,it is necessary to construct a more reasonable and scientific tennis special strength quality evaluation index system and evaluation standards,to provide a basis for the subsequent evaluation,selection,training and so on.Through the methods of expert investigation,mathematical statistics and measurement,this paper studies the evaluation index and standard of the strength quality of the male students in tennis colleges of professional sports colleges.The research findings are as follows:(1)There are three typical first-level indicators which can reflect the special strength quality of male students in tennis colleges of professional sports colleges studied and preliminarily constructed in this paper:upper body strength,trunk strength,lower limb strength;There are 12 secondary indicators: continuous oblique barbell push,push-up,bench press,clean and jerk barbell,sit-up,prone back vibration,snatch,suspension leg lift,squat jump,continuous in-place touch,kettlebell,half squat.(2)The distribution of weight coefficients in the index system is as follows: first-level index:upper limb strength: trunk strength: lower limb strength = 0.32:0.33;Secondary indicators:bench press: push-up: continuous oblique upward push barbell: clean and jerk barbell =0.31:0.27:0.18.0.24;crunches: tummy back vibration: suspension leg: snatch =0.34:0.16:0.29:0.21;keptbell: weighted squat jump: continuous in-place touch height: half squat = 0.26:0.32:0.19.0.23.The results show that the tennis special strength quality evaluation standard system established in this study is reasonable,reliable,and highly operable.The evaluation index system can be used to provide some scientific references for teachers and coaches to adjust training plans and arrange training contents.
