A SPECIAL MOTION AND PERFORMANCE ANALYSIS OF PROFESSIONAL CYCLIST
Keywords: biomechanics, motion analysis, cycling, EMG
AbstractThe biomechanical analysis of sport-motion is a new joint research field of biomechanics and sport medicine. Each cyclist was examined at an own bike mounted on an ergometer for analyzing the motion and the muscle activity at different loading. The ultrasoundbased 3D motion analysis- system and surface EMG signals were used to measure the motion parameters during the cycling. The kinematical parameters, such as the knee angle, and the muscle activity of four muscle groups were determined in every cycle of pedaling. The lactic-acid amount of the capillary-blood and the pulse were checked during the exercise. On the basis of the analysis, it can be established that the movement and the muscle activity are disordered close to the anaerobic threshold; thereafter, they become ordered. The results o the examination give effective help to trainers and athletes to improve the performance.
