So I got a chance to look through Mike’s HRV data. We currently have 110 days of data, with 51 out of 110 days having an HRV score of 80.0 or higher.

Out of the 51 days with scores higher than 80.0, there are 15 days with scores of 85 or higher. They are listed below;

05/6 HRV 87.3 HR 64.1
5/5 HRV 85.3 HR 59.1
4/25 HRV 85.1 HR 67.4
4/23 HRV 85.5 HR 66.5
4/18 HRV 85.1 HR 67.3
4/8 HRV 87.8 HR 60.3
3/14 HRV 88.8 HR 58.4
3/13 HRV 87.9 HR 60.8
2/15 HRV 88.3 HR 58.2
2/11 HRV 86.3 HR 63.0
2/9 HRV 85.6 HR 62.6
1/30 HRV 86.2 HR 59.6
1/27 HRV 87.1 HR 59.9
1/26 HRV 87.5 HR 62.8
1/23 HRV 87.8 HR 53.7

You can see once HRV climbs to 87’s, he has a resting HR of below 60 virtually every time, so there does appear to be a pretty clear correlation between lowest heart rate and highest HRV score. Obviously the sample size is limited, but it’s growing daily!

When I get more time, I can drill down deeper and start to show the effects on HRV of tempo, EMS, and massage. Very interesting stuff!

Tyrone, keep in mind that Mike is also following the recommended Ithlete measurement protocol by taking a standing measurement immediately after waking. I know it’s not ideal to compare Ithlete measurements between two people, but his standing HRV/RHR measurements are better than my lying HRV/RHR measurements! If he were to do a lying measurement, his RHR might get below 40 which makes the standing measurement very necessary for him.

Also, the Ithlete is coming out with a team app now. I bet you could get a beta version of it if you talk to the Ithlete people: http://myithlete.com/blog/?p=1592
