The Accuracy of Heart Rate Monitors vs. Power Meters

Question

What is the measure of effectiveness of fitness efforts using heart rate monitors and fitness power meters?

Answer 1

Your heart can be controlled as Trinity’s data shows a general wearable heart rate monitor to be nervously impacted by the variability because of environmental factors and emotional states. For example, heart rate drift can take place over the progress of the course as the body gets worn out. Power meter manufacturers say of accuracy range of between and 1% which also fluctuates by factors such as temperature. It is wise to perform a zero offset to your cycle power meter prior to any riding as this is helpful to ensure temperature compensation. To categories any body sensors such as the power meters are assumed to have comparatively very uniform readings but as usual both the tools have their own genre of variability.

Comments

The discrepancy between heart rates on the two devices presented is truly disturbing.  That should be tracked down, because really, there should be no difference.  A reason it could occur is due to drop outs, when the Bluetooth is not quite working.  The lower rate monitor would be the one with the drop out.  I have had this with my $30 Amazon chest heart rate monitor once, when it was apparently only picking up half the beats for a while.  In any event, the discrepancy between heart rate monitors should be looked at more closely.  The variance should not be that big.

:13... this shouldn't surprise us. The watches' LED tech is inherently less accurate than the ECG in the chest strap. Plus, watches move around on your wrist which degrades accuracy.

Eight percent difference on HR is pretty significant.

I think using an apple watch would have been much better than the Wahoo Rival which is known for its dramatic inaccuracy. Apple watch and Wahoo chest strap is 99.9% accurate.
