Abstract

This study aimed to clarify the effects of different resisted sled sprint (RSS) loads on the sprinting abilities of junior high school students. Thirty-two junior high school students completed five RSS sessions in a physical education class. Each used a 12-, 14.5-, or 17-kg sled for the RSS training. According to the ratio of sled weight to body mass (%BM), the students were divided into light (25.75 ± 2.57%BM) and heavy (34.46 ± 2.96%BM) groups. Students completed a 50-m run before and after the session, and their running time, running velocity, step frequency, and step length at 50 m and 5 m were calculated. No significant changes were observed in any of the measurements for the 50- and 5-m run for either group. Therefore, the five RSS sessions did not affect performance regardless of load.
