More than you want to know!!!
For an average of a random 10 games this year I burned 12.7 calories per minute. Highest game = 16.02 calories per minute and lowest = 10.55 calories per minute.
This is based upon turning on Heart Rate monitor the time I launch and turning off when I land; so it "includes" water breaks and just sitting there jaw boning, waiting around to pick teams or somebody to get in their boat.
Needless to say this is going to vary according to age and fitness level and how intense one plays. It is also effected by what one does before: warm-up and paddling around the lake. But the average I have posted is simply for my launching for BB and my landing at end.
BB is a strong aerobic workout; without exact calculating but just quickly viewing my data: I am about 12-15 minutes per hour anaerobic during BB.
For myself in a "regular" run I try and shoot for about 10 calories per minute; and for biking pretty close to the same; I do stairs (1000) twice a seek and that works out to about 14 calories per minute.
Hope this gives you an idea of what BB demands physically.
