运用实际测试的方法考察了负重对运动员运动能力的影响。运动员负重后单位体重上的地面支撑反作用力随着负重量的变化而呈规律性变化。运动员在一定范围内负重后原地纵跳的起跳初速度大、F_(max)与 F_(min)的差值变化很大、F_(max)与 F_(min)之间的时间间隔变化并不大、腾空时间延长。 The actual test method was used to examine the influence of weight on the athlete’s athletic ability. The ground support reaction force of unit weight after athletes’ weight changes regularly with the change of negative weight. When the athletes take place in a certain range, the jump speed of the original vertical jump is large, the difference between F_ (max) and F_ (min) varies greatly, and the change of the time interval between F_ (max) and F_ (min) Big, take the time to extend.
