Elucidation of Joint Power Characteristics that Generate High Skating Velocities in Speed Skating
【Supercategory:7. DESCENTE SPORTS SCIENCE Subcategory:7.47 Vol.47】
This study aimed to identify the mechanical factors necessary for achieving higher skating velocities and better race times by estimating blade reaction forces using wireless insole-type foot pressure sensors, and by characterizing lower limb joint torques and joint torque powers during skating under conditions closely simulating actual races. Simulated races were conducted and analyzed with 16 skilled skaters. The results showed that skaters with superior race times and higher velocities exhibited greater hip and knee extension torque power in the right lower limb during both straight and curve skating. Additionally, greater hip abduction torque power was observed in the right lower limb during curve skating. These findings suggest that generating such torque power is critical for achieving better performance. Furthermore, during curve skating, ankle plantarflexion torque power in the right lower limb and knee extension torque power in the left lower limb showed sex-related differences, indicating that these power outputs may be particularly important for female skaters.
