If you're looking for a breakdown of how many calories certain exercises burn per minute, I think they're mostly bullshit. A vast amount of the caloric loss from say, sprinting or any other hard anaerobic work occurs over a period of up to 36 hours afterwards (google "excessive post-exercise oxygen consumption"). Also most numbers you'll find can't account for bodyweight, body composition, ambient temperature, existing fitness levels, not to mention acclimation to the exercise through specificity and well-developed form (think of how inefficiently most people sprint, for example - how could you possibly come out with a standardised rate of energy use for that?).
