| With the development of competitive badminton and the implementation of new rules,badminton competition is becoming more and more intense,accompanied by the increase of athletes'physical consumption.Chinese badminton players have gradually exposed the problems of increasing injuries and physical overdraft after continuous competitions.Based on the above phenomenon,many scholars put forward that the decline of badminton performance in China is closely related to the decline of athletes'physical fitness.By using the methods of literature review,video observation,expert interview and mathematical statistics,this study explores the characteristics of the physical distribution of Chen Long(China)and Kento Momota(Japan)in the men's singles semi-final of the 2019 China Badminton Open,in order to explore a more reasonable way of physical distribution of men's singles players in actual combat.The results show that:(1)The total time of the whole game is 86.1 minutes,the round exercise time is 8.6(4.9?16.4)s,the round interval time is 28.7(22.2?33.7)s,and the exercise/intermission time ratio is 1:2.8.(2)The top two with the highest proportions in the round exercise period are 3?6s and 15-25s,accounting for 28.4%and 20.7%,respectively,and the top two with the highest proportion in the intermission period of the rounds are>30s and 25?30s,accounting for 41.4%and25.0%respectively.(3)The number of beats per round is 9.5(5.0?18.0)beats,and the batting frequency is 1.09 shots/s.(4)There is a significant difference in the usage rate of Chen Long and Kento Momota's main technical actions(?~2=15.99,P<0.05).The usage rate of Chen Long's push,drop,and kill is higher than that of Kento Momota,draw,The usage rate of high ball and diving save is lower than the latter.(5)There is a significant difference in the usage rate of the main technical actions between Chen Long and Kento Momota in the second round(?~2=11.85,P<0.05),while the usage rate of both the first and third rounds is from high to low.The ordering is smash,push,high,draw,drop,and dive save.(6)There is no significant difference between Chen Long and Kento Momota in the average sports time of putting,dropping,dribbling,lobbing,smashing,diving and saving(P>0.05),while Chen Long's main technical action time allocation The order of the ratio from high to low is smash,push,lob,punt,dribble,and dive save,while Kento Momota is smash,lob,push,dribble,dive save,Pounce,(7)Chen Long's number of non-technical moves(wiping the floor,changing the ball)in the third game is higher than Kento Momota.(8)There is a significant difference in the moving trajectory between Chen Long and Kento Momota(?~2=57.09,P<0.01).Among them,the top three in the proportion of Chen Long's trajectory are the diagonally long distance to the right,the longitudinal short distance forward,and the diagonally long distance to the right.The angle is long backward to the right,no movement,and short longitudinally forward.(9)Chen Long's moving distance and return distance in the whole game are much lower than Kento Momota.(10)The movement distance of Chen Long's technique of rubbing the net,pushing the ball,drawing the ball,blocking the net,high ball and lob is significantly lower than that of Kento Momota,while the technique of hooking and smashing the ball is higher than the latter.(11)In addition to the techniques of pushing,picking,and smashing the ball,Chen Long's technical movements of rubbing,hooking,drawing,blocking,high and lob techniques are all lower than Kento Momota. |
