Another post! Sorry! I wondered if anyone on here knows of any workout that would be ideal for testing aerobic decoupling. I’m very much a complete amateur on this subject but would think it’s very handy for Ironman and especially to test the 0.70-0.75 intensity target. So ignoring cardiac drift …

LT1 is the top of Seiler’s Z1. I’ve used that HRV app this week and using the suggested protocol it put my LT1 at 78% of my max HR. I’ve been doing my easy at 67% of max. I do wonder about working closer to this 78% figure. I’ll do it again next week to see if the protocol delivers consistent res…

[IMG_1983.PNG] Reporting back on the use of HRV4Training’s HRV Logger and their DFA analysis to identify the aerobic threshold. Last night I did a slow aerobic 8k run, and the whole run was apparently above the .75 threshold of DFA as indicated by their research. 0.75 is the threshold they belie…

second report on the HRV Logger. It appears not to really work on short intervals like VO2Max. Probably not a surprise, the intervals were 2 minutes and the sampling period is set at two minutes. It did show increased workload and getting closer to aerobic threshold but didn’t register any of the…

Looks like the HRV Logger app is now out for Android users: https://play.google.com/store/apps/details?id=com.asma.hrvlogger

I messed around with the HRV logger app for android this morning a bit, without fully reading the instructions :slight_smile: Initially it looks like my LT1 may be lower power than I thought, but I need to do a few more experiments. My HR was higher than ‘normal’ for the power I was doing today, n…

What’s the conclusion when decoupling is negative? [image]

Don’t think there is a conclusion. I’ve seen negative values on rides where I struggle early on and don’t warm up properly. Heart rate goes through the roof and then settles down. I usually see that with larger percentages. A negative value for a fraction of a percentage might be a good thing. Or m…

[image] conman55: I’ll consider how I felt throughout the ride if I get an odd AD value. It was a fairly normal endurance ride, steady Z2. I felt good. Perhaps what I can say is that 2h is not enough observe decoupling at this intensity. [image]

[image] hdas: What’s the conclusion when decoupling is negative? Basically anything below 4% (including negatives) just means you haven’t pushed enough to find your breaking point - so you need to increase intensity or duration to find where you start to decouple. Two hours is the minimum, b…

[image] trpnhntr: Basically anything below 4% (including negatives) just means you haven’t pushed enough to find your breaking point Agree, but I would add, it’s a good maintenance session. You didn’t waste your time. My Wednesday 2hr Z2 always looks like that. I push it on the weekend rides…
