I have been using mySASY for a month now and I must say I am quite impressed. It is an app that measures variable heart rate every morning and tracks adaptations. It recommends when to take it easy or when go hard to get most out of it. Simply said:) It is science based and very interesting.
Anybody has tried it? or been using it?
Honestly this would be also super interesting topic for Ask a cycling coach episode.
Sounds like HRV4Training. There is a thread on HRV here:
I have tried a few HRV based recovery monitors, Whoop and more recently HRV4Training. Both of them give me a score that kind of corresponds to my recovery most of the time but while it mostly works I have yet to see a benefit with using it for determining if I do a workout or not.
I would love to see something that can tell me precisely how well I have recovered or not and use that to determine my training intensity for the day. However recovery is a massively complex thing and simply using HRV is only a small part of the puzzle. Its interesting for sure but nothing I would put too much stock into.
He’s talking about Heart rate variability, not training with heart rate. HRV is typically measured while you sleep, and may help highlight the things you are referring to as potential reasons to “send it” or not “send it.”
I’ve been “monitoring” it with an Oura ring, but it’s completely unintelligible to me. I can relate better to things like resting heart rate, respiration rate, and body temp, but have no idea what HRV is telling me and I typically don’t listen to it and seem to be fine. I’d be curious what data you’ve found to be actionable using this tool.
One of the advantages of using HRV to help gauge how well you are recovered is that it can give an early warning sign of something wrong before you are displaying any symptoms or are aware of the problem. See this re HRV response to Covid.
Yep, I have seen some super interesting stuff come out of them in relation to that. I still monitor my HRV using HRV4Training every morning and do pay some attention to it but unless I feel like crap and the score has been poor for a couple days I wont alter training based on it alone.
