It may be that speed does not significantly affect calorie burn rate (even though my own experience, not quantitative, suggests that level of exertion does figure). But there is something to be said for faster speeds helping time management. I simply do not have the time to burn a fixed amount of time in 11 minutes per mile.

So a typical workout might be 4x3:00/1:00, 6x2:00/0:40, 6x1:00/0:20, 6x0:30/0:10. The goal was to repeat and complete, go at an intensity where you could repeat at a work intensity-heart rate combination [but just barely].

Hunter-gatherers tended to burn 1000 calories/day on physical activity just doing their usual stuff. And now it seems that our energy balance mechanisms somehow fail when we lose those 1000 calories and adopt sedentary lifestyles.esmithnoreply@blogger.comtag:blogger.com,1999:blog-5880610.post-56748275682695044002013-01-06T23:38:24.751-05:002013-01-06T23:38:24.751-05:00I agree with you on the total time frame.
