Polar Beat VO2Max 'test'

I noticed that the app Polar Beat that I had installed but not looked at has a 5 minute "fitness test" where you basically put the HRM on, start the test an do nothing for 5 minutes. I tried it a few times expecting nonsense but the number it produces (without units) is very close to the VO2Max that my 245 gives, which itself is in line with other Garmins I have had. Looking around, it seems that this type of test from Polar seems to work reasonably OK ncbi.nlm.nih.gov But I don't see what the test can measure other than resting HR and possibly indirectly respiration rate.

If that was VO2Max then an elite level mile speed would be around 6m00; that's a pretty loose interpretation of elite! I did that test a couple of weeks ago and got 49, and I've been pretty consistent with 48/49 as a result whenever I've tried it. Garmin at the moment would give me about 55, but that's on an older watch so the calc isn't that great. Runalyze might put me around 48-50 though for a 5k effort. I agree, I can't see what else it could possibly be measuring though!

I will try in on my rest day when by the evening my resting HR gets down to its real value and see if this gives a different result - in which case this test is about potential rather than reality - having said that I suppose VO2Max could be seen this way.

Must be very low to be scoring that highly on the Polar test. For me at the moment it's not falling much below 55, but when I'm well trained it will be consistently around 48, at which point I'll be around 18m30 for a 5k (depending on specificity of training).

The_Saint May 2021 5:17pm, 6 May 2021 6,806 posts	Quote Pin The_Saint I have been hooked up to medical grade ECGs or heart rate monitors a few times in recent years either as a volunteer in university fitness studies or for outpatient procedures and my resting HR always gets remarked on. Even experts get caught up in the "only Tour de France cyclists have very low RHR" mythology. There is an exercise component sure as my RHR was always about 55 before I was a runner.
