Figuring out how many calories you burn when running is, on a simple level, a fairly straightforward calculation. Most experts (and lots of studies) suggest that a person of average weight burns about 100 calories in a mile of running.
On average, the men burned 9.2 calories per minute while jogging (or about 230 calories for a 25-minute jog) and had a mean intensity of 8.5 METs, compared to 4.2 calories per minute (105 calories per session) and 6 METs during sex.
