惯相运动与逆相运动的交替

The Alternation of Habitual Motion and Reversed Motion

体育教学多以惯相运动的方式进行，忽略了逆相运动对人体产生的影响。本人在教学实验中发现，惯相与逆相运动的交替练习，能极大地促进学生运动技能的掌握，提高身体的协调能力。

In the teaching of physical education, we usual do in the way of habitual motion. Thus we ignore the effect of reversed motion on human body. In my teaching practice, I find that the alternative exercise of habitual and reversed motions will promote greatly the students mastery of sport teachniques and thus improve the coordination of their bodies.
