Key-Link Pacing Feature and Theoretical Design for Full Course Pacing in Women's 500m Speed Skating

Purpose:This study wanted to grasp the key-link pacing feature to offer the theoretical foundation for diagnosing and optimizing full course pacing. Methods:By the methods of literature review,game testing and mathematical statistics,the article analyzed the key-link pacing feature and theoretically designed full course pacing in women's 500 m speed skating. Results:1) Elite athletes have excellent ability in the first 100 m,and the score within10. 4 second is the basis for good performance;the percentage score of the first 100 m is highly negative correlated with the total score,27. 8% is reasonable in this section. 2) When the speeds of going into the first bend and the second bend inner lanes are over 91% and 97% maximum speed respectively,speed will be forced to decrease. 3)Accelerating immediately after outing of the second bend outer lane will let speed increased sharply,and the general rule used by elite athletes after outing of the second bend inner lane is firstly accelerated by inertia ion and then buffered. 3) The full-course spacing mode can diagnose and optimize training. Conclusions:1) Outstanding ability in the first 100 m is the basis for excellent performance,but athletes should reasonably control acceleration pace in this phase;2) Great attention on individual's largest controllable speed of going into bend inner lane should be paid to avoid dropping of speed and fall. 3) Athletes should be buffered immediately when outing of the second bend outer lane,accelerated firstly by inertial and then buffered.
