I'm well aware that the calorie counters on machines are not accurate, but how accurate is the calorie counters on the Polar HR watches? For those not familiar with them, you enter your height, weight, age, etc, and it measures your HR and calories burned during a workout. How accurate are these as far as calories burned?

Tim,

I haven't heard of this, and wonder the theory behind it. Calories consumed in human is determined by oxygen consumption. (VO2) There are a number of exercises where VO2 has been measured, but the one I'm familiar with is walking/running and is the basis for the treadmill test cardiologist use to measure cardiac performance. How a watch can determine this is beyond me, but I'd be intersted in learning.

I think they're basing it soley on heart rate. I was wondering if more than heart rate is needed to determine accurate calories burned during a workout.
