Research On The Commonness Of The One Hand Shot On The Shoulder Of The Active NBA Top Shooters

This research attempts to summarize and summarize the common points of one-handed shoulder shooting of outstanding NBA active pitchers through literature review,video analysis,questionnaire survey and other research methods,and to analyze the common points of one-handed shoulder shooting of outstanding NBA active pitchers.In order to promote the improvement of basketball level in our country,keep up with the trend of world basketball,promote the development of basketball in our country,and step into the ranks of first-class strong teams in the world at an early date,some references and suggestions on shooting are provided for our basketball workers in teaching,training and competition.Through summarizing and analyzing the shooting movements of 10 excellent NBA active shooters,the following conclusions are drawn:(1)In the preparation stage of shooting,the position of lifting the ball is usually between the head and shoulder,which is the commonness of this action.It does not affect the field of vision,but also can get better shooting power effect.(2)The assistant handball is a common action on one side of the ball,so that the ball can be stabilized in the shooter.The assistant hand hardly needs any other action when shooting.It has little interference to the shooter and is more conducive to shooting.(3)Shooting before the top of the body's center of gravity can make the body reach a more stable state and make the shooting more efficient,so it is a better time to shoot before the top of the body's center of gravity.(4)When shooting,the common movement of upper limbs is that both shoulder joints are rotated around the vertical axis,so that the muscles around shoulder joint are relaxed and the corresponding shooting effect can be achieved;the commonflexion angle of elbow joint in the shooting preparation stage is acute angle,but there is no obvious common flexion angle of shoulder at this time,and there is a big difference between athletes.(5)The common movements of the trunk are: the head should be straight and no roll when shooting,and the trunk and spine should be straight and no flexion and extension when shooting.Such movements can maintain the stability of the body posture and allow the strength of the lower limbs to transmit efficiently to the upper limbs.(6)Common movement of lower limbs in shooting: 1.There is no big movement of hip joint.There is no obvious flexion and extension in flexion and extension,and there is no choice of non-extension in abduction and non-abduction.2.The commonness of knee rotation in shooting is no rotation,which can efficiently transmit strength upward and reduce the probability of knee joint injury;3.The commonness of ankle flexion and extension.Sex raises the heel and lets the forefoot touch the ground to make the ankle joint in an extended state when preparing for posture,which can reduce the time of hand release and improve the "pre-tension" of the ankle joint.
