You might be able to estimate the amount of energy by using the volume of their lungs to find the amount of oxygen they have, then use this to calculate how much 'sugar' can be reacted with it, thus giving you the total usable energy.You may even be able to compensate for the amount of residual oxygen left in the lungs. This would of course have some significant error, as they probably leave some reserve, and have less blood oxygen at the end of the dive than at the beginning.

- CapitalistCartr 10y agoI eat about 2600-3000 per day. So, for a human, 5000 in 12 minutes would be astounding.
