How many times has this happened to you?
下面的情況你遇到過多少次？
You start to fall, but then catch yourself and continue on your way.
你即將摔倒，但又保持住了平衡繼續(xù)走路。
Well, new research shows that falling and catching yourself actually happens every time we take a step.
一項(xiàng)新的研究發(fā)現(xiàn)每次走路的時(shí)候，這種即將摔倒自己又保持平衡的事都會(huì)發(fā)生。
And that we precisely place our feet as we walk to avoid taking a tumble during this ambulatory balancing act.
在走路保持平衡過程中，我們自己會(huì)盡量避免摔倒。
The study is in the journal Biology Letters.
這項(xiàng)研究已經(jīng)在生物學(xué)雜志上發(fā)表。
When humans walk, we put one foot in front of the other.
人類走路的時(shí)候，一只腳在前，一只腳在后。
But the way each foot lands can vary from step to step.
但是每只腳落地的方式都不相同。
This variation in foot placement can appear pretty random.
腳的這種變化呈現(xiàn)隨機(jī)形式。
But researchers decided to take a closer look.
但是研究者們決定近距離進(jìn)行觀察。
They fitted 10 volunteers with motion caption markers and then watched as the subjects walked on a treadmill.
他們?yōu)?0名志愿者安裝了動(dòng)作捕捉系統(tǒng)，然后觀察他們在走步機(jī)上走路的樣子。
The investigators discovered that that they could predict exactly where each foot would fall based on the movement of the person's pelvis during the previous step.
研究人員隨后發(fā)現(xiàn)他們能夠根據(jù)之前步伐中的骨盆運(yùn)動(dòng)，精確地預(yù)測每一腳的落點(diǎn)。
The body falls forward and sideways as we walk…and the feet come down in a way that restores our balance.
我們走路時(shí)身體會(huì)向前傾…而雙腳則在同一路徑上落下以保持身體平衡。
The findings could be useful for developing ways to help people with movement disorders regain their stability.
這一發(fā)現(xiàn)對有運(yùn)動(dòng)障礙的人恢復(fù)平衡很有幫助。
The info could also make walking robots more surefooted.
這個(gè)消息同樣會(huì)使得走路機(jī)器人更加趨于平穩(wěn)。
So they don't, ya know, fall down on the job.
當(dāng)然機(jī)器人們并未在執(zhí)行任務(wù)途中摔倒過。
