and it was a significant decrease

with the oxygen consumption
以及耗氧量数据进行了很好的记录

didn't have a change in the total activity count

Here we see across the whole sample
从总体上来说
the total amount of time spent in sedentary

very low level activity increased 20 minutes a day after sleep deprivation
也就是低度运动上花费的时间每天增加20分钟
v.s. 8.5-hour sleep
相比于每天睡眠8.5小时的状况下
had slight decrease in the light level of activity
