在短路的身体素质教学中,要经常注意柔韧性的训练。因为柔韧性是决定动作幅度的关键因素。短路运动员要增大步幅,很大程度上在于加大腾空时两腿的夹角。有资料表明,运动员在腾空时两大腿间的夹角加大5°～7°,步幅可增加10～12厘米。因此,加强柔韧性练习具有重要意义。 基本练习方法为拉伸法,分动力性拉伸和静力性拉伸。这两种拉伸法又都可采用主动和被动两种练习形式。在运用拉伸法发展柔韧素质时,要掌握好练习的强度、重复次数
In short-term physical quality teaching, we must always pay attention to the training of flexibility. Because flexibility is the key factor that determines the range of motion. Short-circuit athletes to increase the pace, largely due to increase the angle between the legs when vacated. Data show that when the players vacated the angle between the two legs increased 5 ° ~ 7 °, the pace can increase 10 ~ 12 cm. Therefore, to strengthen the flexibility of practice is of great significance. The basic method of practice for the stretch method, sub-dynamic stretch and static stretch. Both of these stretching methods can take both active and passive forms of practice. In the use of stretch method to develop the flexibility of quality, to master the intensity of practice, the number of repetitions
