クラウチング・スタートにおいて足の配置をきめる要因

抄録

Four subjects (who were good runners) were employed in this study. (Table. 1) Running was performed gets the strobo-scope flash interrupted every 1/20 second in darken ground. The light-trace of the toe point was taken photograph by means of an ordinary camera with 200 millimeter telephoto lens. When starting, the stronger leg should be placed on the front block, and quicker leg should be placed on the rear block. It must be determined that the front leg have priority over the back leg. Four sprinters achieved better time in a 5 meter sprint by using the stronger leg against the front block. Best results were gained by keeping the back leg concentrating upon the powerful drive off the lead leg.
