Fifteen Minutes of Disagreement

Finish screen view for the 10K rowing session.

Today’s workouts consisted of a few morning sessions on the SkiErg and a 10,000 meter rowing session in the afternoon.

The title of today’s blog post refers to the fact that the two heart rate monitors I was simultaneously using during the 10K session had a pointless argument during the first fifteen minutes of that session.

I wore two heart rate monitors: A Garmin chest strap (which is what RowPro used for its heart rate data) and a heart rate monitor on the wrist. The heart rate monitor on the wrist showed a reading of near 100 BPM for the entire rowing session but the RowPro heart rate display and graph showed an impossibly low heart rate – which was about half or less than half of what it should have been, for the first 15 minutes of the session.

The two heart rate monitors continued their pointless argument, in radical disagreement for the first fifteen minutes, after which the RowPro heart data gradually rose and finally began displaying normal readings that agreed with the wrist heart rate monitor.
