Recovery Profile: Morning vs. Nocturnal HRV Data

Hello,

I’d like to ask about the recovery profile that Athletica builds. Athletica uses HRV from overnight recordings, but I measure HRV every morning for 3 minutes with HRV4Training and a chest strap. I can also send overnight HRV data from my Oura Ring to Athletica.

Which data should be considered valid—morning or overnight? Based on the articles and studies I’ve read, morning measurements seem more important for adaptation because they reflect readiness for the current day.

What is most suitable for Athletica’s system: should I send morning or overnight HRV data?

SLEEP HRV is best for identifying chronic/systemic stress, while the morning HRV is best for understanding whether you’re ready for a workout.

The first is for assessing stress, the second for training readiness…this is how I evaluate it.

I let Garmin determine the HRV for Athletica while using the morning reading of HRV on Training4HRV to determine my training readiness. Training4HRV does not connect to Athletica, so it’s a stand alone.

Hello,
I also monitor readiness with HRV4Training, which I send into Athletica via Intervals.icu. I’ve read that for day-to-day readiness and same‑day training adjustments it’s better to rely on a morning measurement, so I record my overnight HRV separately. I’m unsure, though, whether Athletica prefers overnight HRV instead, as mentioned in the newsletter and shown in the Recovery Profile.
What’s the recommended way to use the Recovery Profile and make adjustments based on it? If a single‑day reading drops below my normal and the 7‑day range, do you already modify that day’s session, or keep the plan as is and only adjust on subsequent days if values remain below baseline? Thank you

Glad you’re able to connect it with Intervals!

Typically, if my HRV4training is green, I’m good to go. If it’s yellow, I double check how I’m feeling and go from there. If it’s red, I generally take the day off since I’ve learned that HRV4Training usually is showing that I’m getting sick.

If the trendlines are going down, I will also take a day off or easy just in case I’m getting sick.

MARCO ALTINI says that the nighttime reading indicates how the body is responding to chronic stress (life, work, family, and sports)…

The morning reading indicates whether and how we’re ready to absorb the training (not whether we’re ready for the performance… that is, even if it’s low, we can perform at our best, like on race day).

Protocol: Get up, go to the bathroom, water, coffee, sit down, and measure.

Hi,
I’ve noticed that after days of decreased HRV and high fatigue, I decided to replace today’s Threshold Intervals workout via the Workout Wizard—what Athletica presents as a “weapon.” To my surprise, it suggested 1 h 30 min of light rowing, which I find excessively long for recovery. Is this really intentional?
