Technical Characteristics Study of the Sliding Action Based on Biomechanical Analysis

摘要

In this study, it studies speed skating in the sliding movement, first analyzes the force condition of the human body in a cycle of the speed skating movement, describes the factors that affect the speed skating results through force analysis and conducts data analysis on knee joint angle, pedal speed and pedal force in the skating. The research results show that the peak of pedal force appears when the knee joint angle is 130° through the force signal; the maximum force is equivalent to 150% of body weight and when the pedal-off speed exceeds its maximum value it will suddenly drop, during speed skating process the adjustment of posture should also be noted, preferably close to streamline, thus it can reduce the resistance of air pressure, the smoothness of the race suits also has a small impact on competition performance.
