引用一段不久前看过的Eat and Run里的说法: （这本书很好看，应该隔一段时间就再看一遍。引用部分是从别的论坛里扒的，说的很有道理）
“In an ideal world, all runners would land on their forefoot or midfoot
when they run. In an ideal world, though, all runners would be lean, healthy
, and have spent most of their lives clocking 5-minute miles.
There’s no question that forefoot striking is more efficient than heel
striking. It uses the elasticity of the Achilles tendon and the arch of the
foot to translate the body’s downward force into forward motion. Less
energy is lost to the ground. It’s also a given that landing on the
forefoot, as barefoot runners do, prevents the heel striking that cushioned
shoes enable, which can lead to so many joint and tendon injuries.
But it’s also true that it’s not a perfect world. Beginners run. Out-of-
shape people run. And for them forefoot striking might increase the risk of
tendonitis or other soft tissue injury. That’s especially true for anyone
who hasn’t grown up running barefoot through rural Kenya.
Most researchers would say that a midfoot landing is the most efficient and
shock-absorbing technique. But there are people who fall on both ends of the
spectrum— heel strikers and those who run on the balls of their feet— and
they do fine.
What’s important isn’t what part of the foot you strike but where it
strikes. It should land slightly in front of your center of mass or right
underneath it. When you have a high stride rate and land with the body centered over the foot, you won’t be slamming down hard, even if you connect with the heel."
