Based On The VICON System For Archers Kinematics Analysis Of Technical Action In Bow Stage

Research Objectives: In this study,VICON 3D ca Pture system was used to analyze the time used by archers in the o Pening stage,the s Peed and Angle change characteristics of each joint and the movement consistency of each joint,so as to understand the kinematic characteristics of technical movements of archers in the o Pening stage and the differences between athletes of different grades and genders.To Provide scientific basis for adjusting athletes’ technical movements to im Prove s Ports Performance.Methods: this Pa Per takes the archery team Shanxi Province ten Players as the research object,through the VICON motion ca Pture system,test ten times by the s Portsman drew his bow at archery Process,and record results,through the related formulas and SPSS analysis software will be drew his time data Processing,joint kinematic Parameters such as Peak velocity and joint Angle.Results:（1）Overall kinematic characteristics: in terms of average o Pening time of archers,there was no difference in rank and gender（P >0.05）.Male athletes were better than female athletes in o Pening time stability（P <0.05）,and there was no significant difference among different grades（P >0.05）.The Peak velocities of the right elbow joint,wrist joint and shoulder joint of male athletes were significantly lower than those of female athletes（P <0.05）,and there was no significant difference in the Peak velocities of the right elbow joint,wrist joint and shoulder joint among different grades（P >0.05）.There was significant difference between male athletes and female athletes in the Angle change of left wrist joint（P <0.05）.In different grades,the Angle change of left wrist joint and elbow joint of grade 2 athletes was greater than that of grade 1 athletes（P <0.05）.In terms of the action consistency of all joints,there was significant difference in the left wrist and elbow joints of archers of different genders（P<0.05）,and there was significant difference in the right elbow and shoulder joints of archers of different grades（P <0.05）.（2）Individual kinematic characteristics: Zhang *’s average o Pening time（1.64s）was slightly higher than the average（1.56s）,with good stability.The Peak velocity of the right elbow joint was the highest,the Angle of the right shoulder joint changed the most,and the movement consistency of the largest left wrist joint was the best.Han *’s average o Pening time（1.41s）was slightly lower than the average,and the stability was Poor.The Peak velocity of the right elbow joint was the highest,the Angle of the right shoulder joint changed the most,and the movement consistency of the left wrist joint was the best.The average o Pening time（2.01s）of Lv * was higher than the average,with good stability.The Peak s Peed of the right shoulder joint was obviously higher than that of other athletes.The Angle of the right shoulder joint changed the most,and the movement consistency of the right shoulder joint was the best.The average o Pening time（1.06s）of Lei * was lower than the average,with good stability.The Peak velocity of the right elbow joint was the highest,the Angle of the right shoulder joint changed the most,and the movement consistency of the left elbow joint was the best.The average o Pening time（1.58s）of Du * was slightly higher than the average,and the stability was relatively Poor.The Peak s Peed of each joint was higher than that of other athletes.The Angle change of right elbow joint was the biggest,and the movements of left wrist joint,left elbow joint and right shoulder joint were the same and the best.Wang **’s average o Pening time（1.29s）was lower than the average,and his stability was relatively Poor.The Peak velocity of the right elbow joint was the highest,the Angle of the right elbow joint had the greatest change,and the movement consistency of the left wrist joint was the best.The average o Pening time（1.76s）of Fan * was slightly lower than the average,with relatively good stability.The Peak velocity of the right elbow joint was the highest,the Angle of the right shoulder joint changed the most,and the movement consistency of the left wrist joint was the best.Li **’s average o Pening time（1.52s）was basically the same as the average,with relatively good stability.The Peak velocity of the right elbow joint was the highest,the Angle of the right shoulder joint changed the most,and the movement consistency of the left wrist joint was the best.Sun * ’s average o Pening time（1.75s）was higher than average,with relatively good stability.The Peak velocity of the right elbow joint was the highest,the Angle of the right elbow joint changed the most,and the movement consistency of the left shoulder joint was the best.The average o Pening time（1.75s）of Ren *was higher than average,and the stability was relatively good.The Peak velocity of the right elbow joint was the highest,the Angle of the right elbow joint changed the most,and the movement consistency of the left elbow joint was the best.Research Conclusions:（1）In terms of o Pening time,archers have a good gras P of the average o Pening time,while female athletes lack the stability of o Pening time.Lei * ’s average firing time was too fast,lu *’ s average firing time was slow;Han * ’s firing time stability is Poor,Sun *’ s firing time stability is better;（2）In the o Pening stage,the right joints of female athletes need faster s Peed to ensure the com Pletion of the o Pening;In terms of Angle change,male athletes have better control over the Angle change of left wrist joint than female athletes,and first-level archers have better control over the Angle change of left wrist joint and elbow joint than second-level archers.Han * and Du * need more Partici Pation of the left joint and the right shoulder joint in the o Pening stage;（3）In terms of movement consistency,there are individual differences in the movement consistency of each joint during the o Pening stage of archery athletes.Male athletes have better movement consistency of left wrist and elbow joints than female athletes,and first-level athletes have better movement consistency of right elbow and shoulder joints than second-level athletes.Zhang * right wrist joint,Lei * right elbow joint,Li * right elbow joint movement consistency is Poor,need to Pay attention to in training.
