Post-cardio energy burning higher in thin athletes
In the Canadian study 7 men with a fat percentage of less than 16 percent and 8 men with a fat percentage of over 25 percent had to cycle for half an hour at more than 60 percent intensity. The researchers monitored the subjects' blood for the first 2 hours after the exercise session. The first thing they noticed was that the cortisol level rose more in the fat subjects and the growth hormone level rose more in the thin subjects.
After the exercise session the subjects' oxygen expenditure – i.e. their EPOC – rose 28 percent more in the thin subjects than in the fat subjects.
The higher EPOC in the thin men is accompanied by a higher GH level. Unlikely to be a coincidence, the researchers think.
