转动惯量的大小、分布和转轴的位置是决定720°旋风脚能否顺利完成的关键,好的身体姿态能促进转动惯量和角速度的调整。腾空高度是影响720°旋风脚空中转体与落地稳定性的重要因素,空中转体的速度能弥补运动员腾空高度不够的问题。在720°旋风脚踏跳时,身体已经绕纵轴拧转了一定的角度,这正是因为偏心力矩的存在而产生的,在适当的倾斜角度内产生的偏心力矩对空中完成720°旋风脚转体非常有利。
Moment of inertia size, distribution and position of the shaft is the key to determine whether the 720 ° cyclone foot can be successfully completed, good body posture can promote the adjustment of moment of inertia and angular velocity. The vacant height is an important factor that affects the stability of the swivel body and the landing of the 720 ° cyclone foot. The speed of the air swivel can make up the shortage of the athlete’s vacancy. At 720 ° cyclone beating, the body has been twisted around the longitudinal axis of a certain angle, which is precisely because of the existence of eccentric moments generated in the appropriate tilt angle of the eccentric torque on the completion of the 720 ° cyclone feet in the air Swivel is very favorable.
