柔軟度與跑步 - 路跑 Road Running

大家好！

今天在NPR的Fresh Air節目裡面，聽到一個有趣的議題，
這個討論其實還顛覆了我個人的一些觀念，
所以，我想要在這邊跟各位先進請教一下，是否大家曾經聽過類似的觀念：

以下是原文的出處：
Stand Up, Walk Around, Even Just For '20 Minutes'

我把個人覺得有趣的部份特別挑出來：
"...because there are some studies that clearly indicate that being
very flexible is not good for athletics, and that's especially true
if you're a runner. If you have really flexible hamstring muscles,
you tend to be less efficient as a runner. You actually use more oxygen.
So when I became a little less flexible, as I grew older,
I actually became a faster runner, which was interesting.
And that's because a really tight muscle is like a very well-stretched
piece of elastic, and it returns energy extremely efficiently.
So if you have tight hamstring muscles, you can be a very fast runner.
You're also somewhat prone to more injury"

這裡的意思應該是說，你的腿部肌肉如果愈緊崩，你就會跑得愈快？
但是你也比較容易受傷？

請問大家平常參加比賽會用這種方式來提升成績嗎？

順便貼一下這本書的相關連結好了：
