摘要：The purpose of this study was to clarify the relation between the knee extensor power and ball speed (velocity) as an index of kicking abilities in soccer players. Forty six subjects from the university soccer club participated to the experiment. The knee extensor power was measured with a Inertia Ergometer, and the work loads applied in the experiment were two kinds ; heavy load (EQ.M. 355.1kg) and light load (EQ.M. 27.8kg). Ball speed was measured with Speed Meter which was deviced by the authors to make it related to generating capacity. And the kicking style applied in the experiment were instep-kick. It was found that the correlation between the knee extensor power and ball speed was statistically high, and that both power and speed abovementioned increased as the years of experience in soccer increased.
