The biomechanical analysis of sport-motion is a new, joint research field of biomechanics and sport medicine. Each cyclist was examined at own bike mounted on an ergometer for analyzing of motion and of muscle activity at different loading. The ultrasound-based 3D motion analysis-system and surface EMG signals were used to measure the motion parameters during 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 was checked during the exercise. On the basis of the analysis it can be established that the movement and the muscle activity is disordered close to the anaerobic threshold, thereafter they become ordered. The results of the examination give effective help to trainers and athletes to increase the performance.
