对蹲踞式起跑两种预备姿势的力学分析

The Mechanical Analysis of two Probationary Positions for the Squatting Start

笔者根据目前被广泛采用的两种起跑姿势依据力学原理对其分析比较，以利于在我们的田径教学和训练中根据具体情况，更为合理的采用起跑预备姿势。

The author analyses this technology on the basis of the two preparations of the squatted start of race now adoptted widely and the biomechanics princople in order to utilize reasonable preparation of the start of race according to the concrete conditions during the track and field teaching and training.
