- This study aimed to investigate the factors related to reduction of short-track speed-skating lap time by examining the relationships between lap time, skating trajectory, skating speed, average section speed, and excess distance in a curved section during maximum effort. The study included 8 male skaters (age, 21 ± 5 yr, height, 1.67 ± 0.05 m, weight, 63.9 ± 4.7 kg), who skated for 3 laps with maximum effort. The curve section was defined as C1 for the first half up to the midpoint of the curve and C2 for the second half after the midpoint. The time taken in the first half of the second lap, skating trajectory, skating speed, change of speed, section average speed, and excess distance covered in the curved section were calculated. The skating speed was expressed as 100% for the entire curved section. The following results were obtained:
1) All subjects moved from the outside to the inside of the course in C1 and from the inside to the outside in C2.
2) Significantly negative relationships were observed between the half lap time and section average speed as well as skating speed at the starts and ends of the sections in C1 and C2 (p<0.05). Furthermore, significantly positive relationships were observed between the section average speed and the starts of the sections in C1 and C2 (p<0.05).
3) No significant relationships were found between the section average speed and excess distance in C1 and C2.
4) The skating speeds at 50% and 100% were significantly lower than that at 0% (p<0.05). The section average speed in C2 was lower than that in C1 (p<0.05).M
5) In C1, some skaters achieved a higher section average speed with a shorter excess distance, while others had a lower section average speed with a greater excess distance.
These results suggest that, in order to shorten the half lap time, it is important to enter C1 with a higher skating speed and maintain this higher speed at the end of the C2, rather than reduce the excess distance in C1. - 出版者・発行元
