直击里约奥运：领奖台之外的趣闻轶事

Cyclists have their sock length measured
工作人员会在自行车选手上场前测量他们袜子的长度

The sight of officials measuring the hosiery of cycling competitors is one of the event's odder spectacles.
工作人员在赛场上测量骑行选手袜子长度？这堪称奥运最诡异的奇观之一。

But under rules introduced in 2012 by Union Cycliste Internationale, the governing body of sports cycling, socks "must not exceed the mid-distance between the ankle and the knee".
但依据国际自行车联盟（UCI）在2012年出台的新规定，自行车体育主管团体决定，袜子的长度“不可超过脚踝和膝盖间距离的1/2”。

This is intended to prevent the use of compression socks, which it's thought can aid recovery and boost performance.
这是为了防止运动员穿弹力袜。这种袜子被认为可以帮助运动员恢复体能，进而取得优异的成绩。
