Growth and aging
The purposes of this study were to investigate the run-up speed parameters of the elementary long jumpers and to obtain coaching suggestions on the run-up techniques for the coaches. Subjects were nineteen male and female elementary school long jumpers who participated in an athletics competition held in Japan. The run-up speed was collected by using a laser speed apparatus. There was a significant positive relationship between the official jumping distance and the maximum speed. This study revealed that reaching the maximum run-up speed as close to the take-off line as possible would help to maintain the run-up speed and to obtain large the take-off speed and the jumping distance.
