我国跳远水平远落后于世界优秀选手,怎样提高跳远运动成绩是我们广大体育工作者在理论和实践中急需解决的课题。跳远运动属斜抛运动,是以克服自身重力和空气阻力以求获得最大远度为目的。根据斜抛运动的远度公式S=V02sin2a/g。可知,跳跃的远度受腾起的速度和腾起角两个因素的制约。人体要跳得远,就必须通过特有的运动形式(如加速助跑、爆发起跳),产生尽量快的跳跃腾起初速度和最适宜的腾起角度。腾起角是田径运动术语,也称腾飞角、起飞角。指人体腾起时初速度的方向与水平面的夹角。可以这样认为适宜的起跳角度,
The level of long jump in our country lags behind the best players in the world. How to improve the performance of long jump is an urgent problem to be solved by our sportsmen in theory and practice. Long jump sports are inclined throwing exercise, is to overcome their own gravity and air resistance in order to obtain the maximum distance for the purpose. According to the oblique throwing motion distance formula S = V02sin2a / g. We can see that the jumping distance by the rising speed and rising angle of two factors. The human body to go far, we must through the unique forms of exercise (such as accelerating run-off, burst off), as fast as possible to jump start Teng speed and the most appropriate angle to rise. Starting point is the term athletics, also known as takeoff angle, take-off corner. Refers to the beginning of the human body when the speed of the direction of the angle with the horizontal plane. This can be considered appropriate take-off point of view,
