One 30 minute session or three 10 minute sessions?

This has probably been asked before but I couldn't find it in google, so... Which would burn more calories in one day, 1 30 minute session of aerobic exercise or 3 10 minute sessions of aerobic exercise? I would guess 3 10 minute sessions would burn more calories through the day because you continue to burn more after a workout and so you are getting 3 boosts throughout the day instead of just one. Is that a correct guess?

Research was reported somewhere earlier this year that said 30 minutes was better. This was based upon research. I don't recall the details of calories.

However, it is clear to me that with 30 minutes your muscles will warmup and work better while with only ten minutes your muscles will just be warming up each time and thus not as efficient.

Actually I recall recent research stating that 3 ten minute sessions a day were more effective in the long-term for actual weight loss... The effect of the activity being cumulative. And apparently, for enough people, it's easier and more likely to happen on a consistent basis.

Just my $.03 worth.

The calories you burn are just the calories you expend in the exercise. If you are using a machine (eg treadmill), they will tell you the calories you burn, you can work it out for yourself.

If the exercise is the same, the calories burnt is the same. Running at 10 kph for 30 minutes burns exactly the same number of calories as running at 10 kph for 10 minutes, three times in a row.

My own personal experience is that you burn slightly more calories if you have two or three shorter sessions than one longer session, because you can sustain a higher intensity for 10 minutes than you can for 30 minutes. If I run continuously for 30 minutes, I can average only 10 kph. By breaking this into three sessions, with a 10 minute break between each, I can average maybe 11 kph.
