>General Running>HRV monitoring
After monitoring my HRV over the last few weeks, I'm left wondering what to make of it. First I had the Ithlete, then I got the sweetBeat App. I'm just baffled at the variations I get from both. Just this morning, i had a reading of 95 sitting down, got up and immediately took a reading standing up with the same app. and got a reading of 38, did another reading right after and got a reading of 51. I notice that my HR goes up by some 30 beats from sitting to standing. I want to understand what could cause such fluctuations. One thing I don't like with both apps is the inhale/exhale ratios because the breaths seem too short for me. For the record, im not stressed, the readings are always within 15 minutes of waking and i train at MAF. Any feedback is greatly appreciated.
Really wonder about it's accuracy. How about you take the old fashioned pulse test with a watch with a second hand and compare.

I've been using ithlete since late last year and find it to be very informative.
I understand your comment about the times to inhale and exhale not fitting into your natural rhythm. I found that I have to inhale quickly and, as the docs suggest, purse my lips when I exhale.
The other issue is to, again as the docs state, take your readings in the same position. I always take my heart rate first and then I sit up, hold the iPhone close to my chest and take my ithlete reading in that position.
What I have found to be anomalous is when I start up ithlete and it's reading my heart rate at twice the actual rate. When that happens I simply quit the application and relaunch it.
Good luck with ithlete!
Runninonion: do you take your HRV standing up or sitting down? Cause that's what I'm struggling to understand. My HRV seems to be considerably lower, way lower, than what I think it "should" be when I'm standing. And that's why I'm concerned. Because how can I get reading in the 90's sitting calmly, and then a 40 to 50 drop as soon as I stand up, I was under the assumption that a 10 point drop is what's "normal" between sitting and standing. I think my question to everyone monitoring HRV is: How much does your HRV change between your sitting and standing position?
I take my RHR with Azumio's "Heart Rate" app. At that point, I'm recumbent. I then sit up, hold my iPhone near my chest and take my HRV reading.
From the docs at this URL:
"Standing vs. supine measurementFirst and foremost, consistent measurements are more important than position. This is because each position appears to provide important data regarding training status. Therefore, pick a position and stick to it 100% of the time for your measurements to be meaningful. Switching positions from day to day will provide skewed data and affect daily ithlete colour indications.
Most users can take their ithlete HRV measurement sitting down.
Extremely fit endurance athletes and individuals with low resting heart rates (<50bpm) are advised to measuring HRV in a standing position. HRV research studies have found that HRV is distorted when lying down in people with very low resting HR (50 and under). Standing (or even sitting) will raise this by a few bpm because your heart has to work a little more to pump blood uphill. However if you find this uncomfortable or would prefer to sit during measurements that is fine – just be consistent!"
I've gotten consistent readings sitting even though my RHR ranges between 39 and 43 BPM.
Re. "everyone monitoring HRV" - you mean there's more than just you and me? ;-)
BTW, any chance you're using FirstBeat Athlete, as well?
Thanks for the feedback Runninonion. I'm not familiar with FirstBeat. I use Sweetbeat.
