游泳运动员都知道,入水后要想有最快的初始速度,必须要靠双腿有力地蹬泳池壁才能获得。在蹬泳池的动作中,刚开始时速度要缓慢,而且要保持身体始终呈流线型向前运动。比赛或训练中,运动员身体准确的流线型使他们能一直保持较高的速度。 Swimmers all know that if you want to have the fastest initial speed after getting into the water, you have to rely on your legs to push the swimming pool wall vigorously. In the action of kicking the swimming pool, the speed should be slow at the beginning, and the body should always be streamlined forward movement. In athletic competitions or training, athletes’ accurate, streamlined shapes keep them at high speeds all the time.
