Timex HRM (T5G971) Accuracy of Calories Burned....

I haven't found any good information on this. I got my HRM yesterday, and used it at the gym today. According to the LifeFitness Tredmill, I burned 325 Kcal. According to the watch, I burned 561 Kcal. The Treadmill readout matches the estimates on the site +/-3%.

I wanted the HRM as much for heart monitoring as estimating calories burned for exercises that don't involved equipment.


[Update: Apparently, the watch uses some formula based on V02max but since that and my age cannot be changed, the results are wrong. So much for cost cutting and not getting the Polar]

Oh, and anyone thinking about getting this watch? The calories burned is useless because the watch doesn't require your age and they don't publish the formula allowing you to adjust it to what ever calories estimator you want to use.

I have an Oregon Scientific I got from Wal-Mart for $38 bucks! It works great. Tells cals burned and you can set the target rate for the work outs! You do enter your wight , hight, and age. It does the rest AWESOME for a simple HRM.

Yes, that is true, but for some interesting reading, google "Why the scales lie" and learn the myths and truths about what the scale is really telling you.
