体育运动训练阻力伞的研制

The Speciality of Resistance Chute in Sport Exercise

依据空气动力学原理，设计研制阻力伞用于体育运动训练中，结果表明随速度提高，阻力伞提供的阻力增大。在运动训练中可根据不同运动项目和不同水平运动员选择不同规格阻力伞进行训练，它可广泛用于田径、自行车、速滑、游泳等项目的训练中。

According to aerodynamic theory, this research made a set of resistance chutein using of sport exercise. The results indicate that athlete of different events and levels can adopt resistance chute of different standard in resistive exercise, this method can largely use in sport exercise including athletics, cyling, skating, swimming and orther events.
