Abstract

To estimate the relationship between kicking ball distance, kicking leg speed, and the volume of kicking leg, young soccer players from elementary school to University students were subjected ball kicking. The distance of the kicked ball was measured and muscle volume of kicking leg was obtained by MRI. The measured kicking speed and ball distance in each group was in the following order: elementary school < junior high school < high school < university. Significant correlation was observed between kicking speed and ball distance. In addition, muscle volume was lowest in elementary school students and highest in University students. Significant correlation was also observed between muscle volume and kicking speed or ball distance. Our results suggest that both kicking speed and muscle volume are important for kicking ball distance, as well as kicking techniques
