Kinematics Research On Badminton Technique Of Badminton Specialized Students In Ordinary Colleges And Universities

Forehand shot high way is the most common shot in badminton,and is also the basis to learn badminton technical movements.So it’s the most representative to study in the badminton various technique for the high ball.This article studies on kinematics of forehand attack high technology with the literature material law, expert interview method, the kinematics experimental measurement methods of ordinary colleges and universities badminton elective students.In a random sample of five mudanjiang normal university badminton elective students as the research object,using two sets of Quintic high-speed camera,for students of a complete set of forehand attack high action,Lille analysis system(APAS) of America and two experimental video cameras for three-dimensional synchronous digital resolution,the kinematics data in obtaining a research institute in the process of experiment.Using the knowledge of kinematics,analysis of measured object moving, the racket back, hit the ball, with the pen, return phase, and the movement of each joint link the kinematics parameters,showing students choosing forehand shot high kinematic characteristics of the movement. To find out the problems existing in the process through the shots technical analysis compares with college students’ professional athletes.Identify the actual gap between it and clear elective students of technology to promote space and the improvement direction,for badminton teaching of specialized course selection and scientific training to provide the reference.The experimental results show that:1. The mobile phase of the early preparation position kinematics characteristics, accord with human body to facilitate power, swivel and mobile.2. Loopback racket back way to facilitate the body potential energy savings, racket back end stance in line with the "beyond the instrument" principle, process, but the whole racket back torso torsional amplitude is small, the racquet arm shoulder joint Angle is small, forearm outward turning is insufficient, the racket back is inadequate.3. The strokes in line with the “whipping”principle,It’s better to use of the waist abdomen strength to hit a racquet arm unbend, not completely don’t reach the highest hit the ball high.4. Return stage, a forward movement way of reversing, an average of 1.216 s, the time is a bit long, return speed is slow.5. Compared to professional athletes in the mobile speed,specially selected students and college students are the most different in amplitude, ball speed.They also have a bigger space technology promotion.
