The purpose of this study was to examine whether male high school students can increase their sprinting velocity by improving sprint techniques according to the sprinting abilities in physical education. The participants were grouped according their sprinting velocity by classification criteria (Nishimura et al., 2016) from 139 male students in the 2nd year of high school. The Normal group and the Poor group had 16 and 18 students, respectively. Participants received sprinting instruction over 6 lessons, and 50m sprinting measurements were taken during the 1st and 6th lessons. Their sprinting motions were recorded approximately 35 m from the start line with a high-speed video camera using the side view angle. For evaluating the sprinting motion, joint and segment angles were obtained from the video. The 2 groups were compared using a paired t-test, which revealed significant differences between the pre and post-measurements. Both the Normal group and the Poor group increased their sprinting velocity by improving not so much common sprint technique as specific sprint technique. This result suggested that high school male students could increase their sprinting velocity by improving techniques according to their sprinting abilities.

This study aims to reveal necessary sprint techniques based on the abilities observed in male high school students. The participants were 232 boys. The experiment involved the participants performing a 50 m sprint.Their sprinting motions were recorded approximately 35 m from the start line with a high-speed video camera using the side view angle. The participants were extracted according to their sprinting velocity by following criteria: the Excellent group (35 students, M + 1SD), Normal group (27 students, M ± 0.25SD), and Poor group (27 students, M−1SD). For evaluating the sprinting motion, joint and segment angles were obtained from the video. These were ankle joint angle, knee joint angle, shank segment angle, thigh segment angle, and body trunk segment angle. The three groups were compared through an analysis of variance to explain the significant differences between them. We identified the techniques each group needed to learn for good sprint ability based on these differences.The results were as follows:1) The sprint techniques that the Normal and Poor groups both needed to acquire were swinging the free leg forward with a flexed knee just after takeoff and pulling the thigh of the free leg up.2) Specific sprint techniques that the Normal group needed to acquire were keeping the knee of the support leg less flexed during the support phase and not leaning the body trunk forward excessively at prophase in support phase.3) Specific sprint techniques that the Poor group needed to acquire were bringing the shank perpendicular to the ground and landing forefoot.
