The figures from
http://web.media.mit.edu/~testarne/TR328/node1.html#tabhumanpower give
the following

sleeping 70 kCal/hr 81W
Sitting 100 116
Driving 140 163
Carpentry 230 268
Hiking 350 407
Swimming 500 698
Dist Run 900 1048
Sprinting 1400 1630

Personally I was surprised at the high figures for the sprinting

Whilst sprinting your lungs cannot deliver enough ovygen so your body steals
it from elsewhere. Quite surprised how close it is therefore to distance
running where breathing is of course essential.
