In addition, the techniques used by domestic and international pole-vaulters were compared and discussed. By comparing the various techniques adopted by these two groups of male pole-vaulters, objective suggestions for improving sports performance could be made. Data were collected from the top three male pole-vaulters in the 2012 National Track and Field Competition. Their movements of the final four strides of the approach run-up and take-off were filmed by a digital camera which took 60 pictures per second and were analyzed by using APAS motion analysis system. The results suggested that: 1.The speed of the final four strides of approach run-up and take-off in domestic pole-vaulters were significantly slower than that in international pole-vaulters. 2.The take-off point of the domestic pole-vaulters was anterior to the vertical line of the grasping point of the upper hand, which in turn affected the loss of the horizontal speed at take-off. 3.The height of the hand-grasping point could affect sports performance. The grasping height of the domestic pole-vaulters was lower than that of the international pole-vaulters. 4.The weight of the pole was another factor affecting sports performance. The weight of the pole used by the domestic pole-vaulters was insufficient to release enough rebound energy for better performance. 5.The domestic pole-vaulter A had best performance for all the measures analyzed in the present study. 6.The domestic pole-vaulter B had the lowest speed for each of the final four strides and take-off. 7.The domestic pole-vaulter C had the greatest loss of speed during the approach run-up. The highest speed appears at the final fourth stride, and it lost 0.21 m/s before take-off.
