is anybody aware of any research that examines the speed at which it becomes easier to jog than walk fast. by easier i mean burn fewer calories. also, i suppose any formula should be influenced by weight of the person.
background: had a discussion with a friend, he has knee problems and was looking at having to walk a HIM. I noted, from my experience, that when you get up to walking faster than about 14 min/mi you may as well jog a 12 min/mi. I read a piece in Runnersworld where he compared his HR on a treadmill and said about 12 min/mi is the crossover line. i've seen formulas on cost of running and walking but they were linear and i don't believe they should be linear. i was planning to do some experiments on a track to see what works for me but thought i'd hit up the brain trust first.
any thoughts?
