Biomechanical Study on The Starting Technical Movement of Track Cycling

In order to standardize and correct the starting technical movement of track cycling,this paper proposed a hypothesis of better crank starting angle on the basis of analyzing the biomechanical factors of starting technology,than use experimental method to verify the hypothesis.In this experiment,11 players of Beijing track cycling team were taken as experimental objects,fixed camera technique and surface electromyography collection technology were used to explore the starting performance with different crank starting angle.The results showed that the biomechanical factors influencing the starting effect can be divided into three categories:internal factors,equipment factors and environmental factors.Finding out the best combining site of these three factors helps to improve the starting performance.The crank starting angle has a significant effect on 60 meters starting performance and 30° is a reasonable crank starting angle.
