The 3000 m steeplechase consists of 28 barriers and seven water-jumping obstacles. The water jump in the 3000 m steeplechase makes it different from the sprint hurdle events. It is important for coaches and athletes to understand how to clear the water jump successfully. I aimed to investigate whether the takeoff and landing distances for the water jump per lap differ between participants with good and worse records.
Data were collected from the men's 3000 m steeplechase races (heats) at Kanto Intercollegiate race. A total of 48 men's performances were analyzed (24 upper group, 24 lower group). Takeoff distance, landing distance and clearance time were analyzed. Takeoff distance, landing distance, total water jump distance and clearance time were subjected to mixed two-way ANOVAs with repeated factors of Lap (lap 1/lap 2/lap 3/lap 4/lap 5/lap 6/lap 7) with Group (upper group/lower group) as a between group factor.
Takeoff distance was longer for upper group (1.43 m) than lower group (1.34 m) ( = .01). Landing distance was longer for upper group (2.95 m) than for lower group (2.74 m) ( = .01) and was longer for lap 1 (2.95 m) than last three laps (lap 5: 2.83 m, lap 6: 2.82 m, lap 7: 2.76 m) ( = .01).
Individuals who were faster in 3000 m steeplechase exhibited longer water jump distance. The effect of fatigue might be greater for landing distance than for takeoff distance. Because the landing distance becomes shorter in the second half of the 3000 m steeplechase, it is important to note that athletes should aim to land as far away from the water pit as possible.
3000 米障碍赛由 28 个障碍和 7 个跳水池障碍物组成。3000 米障碍赛中的跳水池使其与短跑跨栏项目不同。对于教练和运动员来说,了解如何成功地跳过跳水池是很重要的。本研究旨在调查在记录上表现更好和更差的参与者之间,每圈水跳的起跳和着陆距离是否不同。
从关东大学接力赛男子 3000 米障碍赛(预赛)中收集数据。共分析了 48 名男子的表现(24 名上组,24 名下组)。分析了起跳距离、着陆距离和腾空时间。起跳距离、着陆距离、总水跳距离和腾空时间采用重复因素的混合双向方差分析,重复因素为圈数(第 1 圈/第 2 圈/第 3 圈/第 4 圈/第 5 圈/第 6 圈/第 7 圈),组间因素为组(上组/下组)。
上组(1.43m)的起跳距离长于下组(1.34m)(=0.01)。上组(2.95m)的着陆距离长于下组(2.74m)(=0.01),且第 1 圈(2.95m)的着陆距离长于最后三圈(第 5 圈:2.83m,第 6 圈:2.82m,第 7 圈:2.76m)(=0.01)。
在 3000 米障碍赛中速度较快的个体表现出更长的水跳距离。疲劳对着陆距离的影响可能大于起跳距离。由于 3000 米障碍赛的后半段着陆距离会变短,因此运动员应注意尽可能远离跳水池着陆是很重要的。
