发帖数: 6366 | 5 Difference between treadmill and road running:
From the point of view of mechanics there is no difference between belt
moving under our feet and our body moving forward in over ground running
provided the velocity is the same. Indeed we are operating here with the
same speed and consequently with the same forces on the ground and the same
muscular efforts.
While it doesn't matter for mechanics which of the interacting bodies is
moving: the belt or the body, it is not so for biomechanics. It makes a big
difference there. The major one lies in the fact that in treadmill running,
unlike over ground running, our upper body is not moving forward, it's our
feet that are moved backwards by the running belt. This difference creates a
different bio-motor pattern of the movement, where we have to produce some
(otherwise undesirable) activity of the upper body to keep it against
tipping over the support foot on the belt of the treadmill in order to keep
the body in balance. So we have to hold our body to keep it from falling
forward and we have to catch the running belt instead of our falling body.
In over ground running we need to free up our upper body from all possible
tension in order to continue to produce the forward falling at the same rate
and then recruit our feet to pull from the ground up in accordance with the
rate of falling. In treadmill running, pulling the feet from the "ground"
is dictated by the moving belt, which frames accordingly the space and time
of the feet movement. The treadmill belt's velocity helps us to maintain the
rhythm and efforts of pulling in sync, the luxury we don't have in over
ground running. So while running on the treadmill we are not so much
concerned with how fast and how strong we have to pull because it is pre-
determined by the speed of the treadmill belt. In other words, treadmill
running doesn't require us to focus on pulling the foot from the ground as
much as the over ground running does.
So, on the one hand, treadmill's belt movement is a positive factor helping
us to maintain our speed of running, but on the other hand, we do not have
such a "help" on the ground and we have to manage the uneven speed of the
body moving from one support to the other, which requires a much more
sophisticated relationship between our feet and our body and consequently a
much better neuromuscular regulation and coordination. It is well known that
no one from elite athletes could match their treadmill running speed with
over ground running on the same distance. The treadmill running is always
faster because of the above-mentioned "help" from the running belt. That's
why most of them do not use treadmill for the training.
Another negative side of the treadmill running, besides the above- mentioned
, is the risk of landing ahead of GCM and also neuromuscular coordination
that's too stable and developed by the stable velocity of the belt movement,
up to the point of a complete loss of our perception of pulling in sync
with our body falling, but not the belt moving, which helps us to move our
foot from the ground in time. Consequently treadmill training affects our
running on the physiological level as well.

所以经常有的人说，我的主动脚是左脚，为什么我受伤总是右脚：）

简化下：
跑步目的为了减肥健身的，跑treadmill
严肃的runner，路跑
已经天人合一的，无所谓
按班上的观点，能不穿鞋就不穿鞋，但是要慢慢过渡，别受伤

只听说打球有支撑腿的，跑步还有主动脚？
那样对3/3呼吸的人岂不是很痛苦？

rearfoot, 3.4% mid, 1.8% fore (5.9% asymmetry). 到了32km处，相应数字变为：93
%， 3.5%， 0%， 3.5%。 这个统计结果和版上的感觉好像明显不同。
