geeky stuff - formulae for calories burned and vo2 max

[bzar]

Calories Burned/minute source:

there's 2 formulas depending on whether you have your Vo2 max* or not:

Using VO2max
Men: C/min = (-59.3954 + (-36.3781 + 0.271 x age + 0.394 x weight + 0.404 x VO2max + 0.634 x HR))/4.184
Women: C/min = (-59.3954 + (0.274 x age + 0.103 x weight + 0.380 x VO2max + 0.450 x HR)) / 4.184

Without VO2max
Men: C/min = (-55.0969 + 0.6309 x HR + 0.1988 x weight + 0.2017 x age) / 4.184
Women: C/min = (-20.4022 + 0.4472 x HR + 0.1263 x weight + 0.074 x age) / 4.184

weight is in kg; HR = average heart rate during a given activity

Vo2 max:
*if you want to estimate Vo2 max w/out going to a lab, the Kenneth Cooper formula is:

vo2 max in ml/min/kg = (distance-505)/45

distance is in meters, and represents how far you ran in 12 minutes, with maximal effort.

it would be good to do a calculation when you first do a workout, and then later on after you've become used to the workout, assuming your average HR was different.
