The purpose of this study was to analyze cinematographically the hurdling technique. Four healthy college men, aged 19-20 years, participated as subjects. Two of them were good hurdlers, and the others were the unskilled. All subjects performed the 50-m low hurdle run. The height of hurdle was 0.83m, the distance from the start line to the first hurdle was 13.8m, the distance from the last hurdle to the finish line was 3.0m, and the distance between the hurdles was 8.5m. During hurdling, the greater horizontal mean velocity was obtained in the skilled subjects. The take-off distance was shorter in the skilled than in the unskilled. However similar landing distance was obtained in both the skilled and the unskilled. Compared with the unskilled subjects, the center of gravity of the skilled moved smaller vertical distance, and therefore took less time to rise and fall. The faster pick-up of the leading leg, the shorter flight period, and the greater extension of the knee joint of the leading leg was observed in the skilled than in the unskilled. The results indicated that the skilled hurdlers raised slightly their center of gravity and returned quickly to the track not to reduce their horizontal velocity during hurdling.
