One Hand Shoukler Shot Technique Analysis Of Different Levels Of Basketball Players

This study was designed to investigate the basketball player standing hand basket-shooting technical course of action to find out the different levels of basketball players on the joints in the lower limbs during shooting difference in terms of kinematic parameters for the future in teaching practice, training and sports competition athletes proper shooting technique to master and skilled use of theoretical reference.In this paper, the use of expert interviews:interviews with experts basketball, sports biomechanics, sports statistics and other fields of 10; infrared high-speed three-dimensional imaging method:the test subject for the Chinese men’s professional basketball league the Beijing team and the Bayi team players, big schools of Beijing Sport men’s basketball team and the 2014 basketball specialty students a total of 30 people. The use of high-speed three-dimensional imaging Shooting athlete to shoot, use Motion video system for resolution; two-dimensional imaging method:infrared high-speed sync shooting and three-dimensional imaging used:Acquisition athlete shot angle, and use standard evaluation score shooting shot effect; mathematical statistics:chi-square and independent samplesBy athletes at different levels where it is Single-handed To shoot process:feet distance, the angle of hip flexion and extension of time, the angular velocity; the average angular velocity of the knee joint in the process of shooting, flexion and extension of time; shooting shot stage ankle joint angle, angular velocity, in the ankle shooting process flexion and extension time; upper extremity shoulder and elbow in the process of shooting angle, angular velocity, flexion and extension of time; elbow kinematics characteristics were compared when the ball reached the following conclusions:athletes at different levels where it is single-handed To shoot when feet distance, hip flexion angle and angular velocity no time difference. Knee shot athletes at different levels in the course of the average angular velocity; flexion and extension of time are different. Shooting high-level athletes in the knee during the average angular speed, time is short flexion and extension has better shooting results. Different levels of athletes in the shooting hand stage ankle angle, angular velocity, there are differences in the ankle flexion and extension process of shooting time. High-level athletes in shooting ankle during an average angle, angular speed, shorter flexion and extension has better shooting results. Different levels of upper limbs shoulder, elbow angle, angular velocity, flexion and extension of the time there are differences in the process of shooting, wrist flexion and angular velocity at the time there are significant differences. High-level athletes when the ball elbows about 90 degrees, low levels of athletes to less than 90 degrees, high-level athletes with better shooting results.
