Abstract
Aim To study the velocity variations of take-off phase of Chinese male elite broad jump athletes so as to lay a theoretical basis for the improvement of broad jump results.Methods High-speed camera photography and method of film analysis were used to record and analyze the jumping results of 7 male elite Chinese broad jump athletes. The optimal results of these 8 athletes were included in group A,and the worst results in group B.The variations of the body center gravity horizontal velocity and vertical velocity, and the variations of the landing board angle of the jumping foot, buffer and knee angle during the taking off phase were compared and analyzed between A and B groups.Results The decrease of the horizontal velocity and the increase of the vertical velocity were more remarkable in the group A than in the group B during the buffer phase.The Chinese male elite long jumpers tended to incline to a small landing angle when the taking-off foot touched the board coordinated with obvious knee angle variations during the buffer and taking-off phases The horizontal velocity and vertical velocity of the athletes' body center gravity inclined to the tendency of increase when the taking-off foot left the board. The horizontal velocity and vertical velocity showed a great increasing tendency as soon as the foot left the board. Conclusion There is a close correlation between the decrease of horizontal velocity of body center gravity and the increase of vertical velocity among Chinese broad jumpers. 关键词
