Research On Basketball Players' Shooting Technique Based On Acceleration Sensors

With the advancement of technology and the rapid development of the intelligent field,the new sensor technology has been greatly improved,and the application fields are becoming more and more extensive,especially in the field of sports.It can provide data safely and effectively,promote the development of sports,meet the coaches and The athlete's need for the instrument.There have been many studies at home and abroad on the application of acceleration sensors in sports,such as running,swimming,skiing,etc.,whereas,in the field of basketball,there is little research on the application of sensors.In the competitive basketball game,shooting is an important means of scoring,and the shooting rate is the key factor of winning or losing the game.At present,in the research on the shooting rate of basketball at domestic and international,we find that a high shooting rate does not necessarily mean a good shooting stability of the players.The accelerometer measures the maximum acceleration that the player produces when shooting,and provides technical support for measuring the player's shooting stability.Jump shots and free throws are the most common and necessary basic shooting techniques in basketball games.This research mainly adopts the methods of literature review,expert interview,statistics analysis and experiment.And the research objects are professional men's basketball team of Shanxi university(including players of the first team and the second team)and students majoring in physical education(amateur players),focusing on the two basic shooting techniques of free throws and jump shots,and applying acceleration sensors to these two shooting techniques.The player wears an acceleration sensor to perform 10 free throws or jump shots per person,and analyzes the acceleration data generated by the free throw or jump shot,the results are as follows:(1)The average shooting percentage of professional basketball players' free throws and jumpers is significantly higher than that of amateurbasketball players(P<0.01).The average free throw and jump shot percentage of the starters in the professional team is slightly higher than that of the substitutes,but there is no significant difference in free throw and jump shot percentage between them(P>0.05).The rate of free throws and jump shots of the first group was slightly better than the second,but according to the statistical analysis,there was no significant difference in free throw and jump shot percentage between the two teams(P>0.05).(2)Through the stability study of the free throws and jump shots of each player in the professional group of 24 players and the amateur group of10 players,we found that the shooting stability of free throws and jump shots of some amateur players was higher than professional players,and that the shooting stability of some first group players was higher than the second group.Some substitutes player's free throw and jumper shooting stability is higher than the starting player's free throw and jump shot stability.(3)In the basketball program,the coach can better explore some potential players according to the stability data provided by the acceleration sensor,so as to conduct training.In addition,the acceleration sensor can also be used in the daily training of basketball players,which can better correct the shooting technique and improve the shooting stability of basketball players.
