从表 3的部分运动员下肢长度比值数来看 ,我国运动员在重视身高的同时 ,对下肢长度比值数重视不够 ,随着运动员身高的增加 ,下肢长度比值有所下降 ,这一点应该引起重视。否则身高增加 ,身体重心却没有提高 ,而且躯干增长 ,给向上的运动增加了负担 ,下肢相对变短 ,还会影响起跳 In terms of the ratio of lower extremity length of some athletes in Table 3, it is not enough to pay attention to the ratio of lower extremity length while Chinese athletes attach importance to height. Therefore, the ratio of lower limb length should decrease as the height of athlete increases. This point deserves our attention. Otherwise the height increases, the body center of gravity does not improve, but also the trunk growth, to the upward movement increased the burden, the lower limb relatively shorter, will also affect the take-off
