Abstract:
Objective To extract key parameters from a series of biomechanical parameters of rowing technique, so as to provide useful information for coach training. Methods Based on rowing performance of 16 rowers in national team, the factor analysis was used to extract reducing dimension of biomechanical parameters of rowing technique of 80 oxygen utilisation 2 (UT2) training pieces. Results The biomechanical parameters of rowing techniques were classified as technical characteristic factors (angle of 70% peak force, work portion of per 25% stroke length, drive start time, finish slip, position of peak force and angle of peak force), power factor (rower power, average of boat power, port swivel power and stroke swivel power), stroke length factor (catch angle and finish angle) and oar’s motion factor (recovery time, stroke rate and distance of per stroke). Conclusions Monitoring and analyzing these biomechanical factors would contribute coaches and scientific researchers to accurately judge the technical characteristics and shortcomings of rowers.
