스피드 스케이팅 스타트 가속구간과 500m 기록과의 상관관계

The aim of this study was to analyze starting motion of a 500 meter speed skating in junior athlete of speed skating in man and woman. Two camera were used to capture a 30 meter starting. Subjects of this study were speed skating player in man (n=23) and women (n=23). The record of starting phase (from starting line to six step) was measured. The purpose of this study is to analyze basic technology about departure motion of sprinters who are vulnerable in case of international competitions, such as 2018 Pyeongchang Olympic speed skater to support the development of talented athletes. The results of this study as follows :1. The reaction time after the start signal is 0.23∼0.43/sec in the women athletes, and 0.20∼0.36/sec in the men athletes. In addition, time to the first contact of the blade after the starting signal is 0.36∼0.66/sec in the female athletes, and 0.41∼0.68/sec in the athletes. 2. The acceleration interval after the starting signal, duration time between 4th and 6th stroke 1.33∼1.81/sec, 1.90∼2.61/sec in the woman athletes, and 1.28∼1.65/sec, 1.80∼2.26/sec in the men athletes. 3. The correlation between 500m record and interval time of each factor showed the static linear relationship in the woman athletes, but man athletes showed did not show a linear relationship. In explaining the time differences of the start phase of 500m speed skating race, the effectiveness of the starting records to be more important the higher rank player.
