For exercise prescription purposes, it is often assumed that% heart rate reserve (%HRR) provides equivalent intensities to%˙VO 2max.However, a recent study from this laboratory demonstrated that during cycling exercise%HRR is not equivalent to%˙VO 2max, but is instead equivalent to a percentage of the difference between resting and maximal˙VO 2, i.e.,% ˙VO 2 reserve (%˙VO 2R).

The heart rate monitor must be capable of recording the average heart rate and time of the exercise session. But just because your heart rate is a good predictor of your fat loss, you shouldn’t get too carried away and assume that it’s a perfect indicator of your fat loss.
