Does anyone know if the polar H7 would be expected to work for measuring lactate threshold? The manual seems to suggest it needs to be a Garmin chest HRM but reading around it seems others have had some success with 3rd party straps.
I don't have a result yet - but perhaps I'm not trying hard enough!
To confirm general HRV functionality with H7 I've tried it with the 3 minute HRV stress test - and it does seem to give a reading but more often than not I get a reading of 1 (no stress) whenever my heart rate is low. I'm not sure if that's normal for me or a sign that HRV doesn't work very well between H7 & 645M.
