METs and Cooper Points. Cooper gives quite extensive tables of the points worth of various activities in his 'New Aerobics' book. Came out in the early 70s I think, in time to be avidly read by baby-boomers' jogging-crazy years. My understanding was that the tables were based on Cooper's extensive measurements of VO2 (?). IIRC The tables show that the training worth of a mile at 6 minutes and a mile at 10minutes are significantly different (nearly a factor of two IIRC).  Now in various places on the web you can find the worth of various activities expressed in  Metabolic Equivalent aka METs. These tables seem to show that, once you've broken into a run at 5 to 6 mph, the higher metabolic rate of 6 minutes miling over 10 minute miling is nearly offset by the reduced time spent on the exercise - ie calories per mile is nearly independent of running speed.   So what effect did Cooper measure to base his training tables on??  If we understand it, should we include it?
