【Abstract】 The criterion of active stretch was confirmed by analyzing the feature of the force about human-board system.Adopting the same movement of 10 excellent springboard diving man-athletes as research object,the paper kinetically analyzed the opportune of positive stretch.Furthermore the efficient move-condition of the positive stretch and the decisive factor of the best opportune of the positive stretch were put forward.At the same time,the concrete kinetic parameter of the opportune of the positive stretch,on both the general man-athletes and the individual athlete named Wang-tianling,were gained.更多还原
