Strength Training and calories on here

jdavis193

Why is it that the calories are low for strength training on here. My polar FT 60 usually says I burn over 400 cal. with 68 min of weight training on here it's like 200. I always go by polar bc it is more accurate. just curious.

I'm interested to hear what people in the know, have to say here too.

Another poster here has written extensively on this. From what I remember, the polar misinterprets the elevation in heart rate, thus over estimating caloric burn.

Weightlifting does burn calories, but when compared to hard aerobic training, it pales. A hard session with the iron burns only 20% more calories per hour than walking at 4 mph, according to Essentials of Strength Training and Condition.

Edit: Check out Azdak. He has written numerous topics on HRM's.

I read somewhere (no case studies or anything unfortunately, so this is just speculation) that heart rate monitors were meant to measure continuous exertion (i.e. cardio) and aren't quite as accurate for weight lifting. I guess that makes sense to me because if I ran a 5k, stopped for an hour, then ran another 5k I would stop the HRM for that middle hour or it could skew the results.

Speculation as I said, could be wrong.

I will have to research this more. The polar watch I have it is one of the most accurate ones bc you input your Vo2 levels all of your personal info. Where here you just do age height and weight.
