Polar + AI coach: Nightly Recharge in your morning training decision
Polar provides detailed overnight recovery data. SkolCoach combines your sessions, sleep and Nightly Recharge to inform the day's plan.
What the coach imports
- Sessions — heart rate, pace and lap data.
- Sleep — duration, stages and Sleep Plus Stages score.
- Nightly Recharge — overnight recovery through ANS Charge and Sleep Charge.
Training history
The direct Polar connection provides roughly 30 days of history. For older training, connect Polar to intervals.icu under Settings → Connections and import the rest through that bridge.
How Nightly Recharge affects your plan
The coach reads overnight recovery alongside the week's training load. A low charge after a demanding block may be expected; after an easy block, it deserves a closer look. Every adjustment arrives with supporting numbers and is applied only with your approval.
FAQ
What is Nightly Recharge in plain English?
It estimates how well the night restored your autonomic nervous system (ANS) and your body overall. A high charge supports planned training; a low charge suggests moderation. SkolCoach looks at the trend rather than reacting to one night.
Why is only 30 days of history available?
That is a limitation of Polar's direct API. Connect Polar to intervals.icu to import your complete history without that restriction.
I use both Polar and Oura — which matters more?
Both add value: Polar records sessions and Nightly Recharge, while Oura provides Readiness and sleep stages. The coach combines the sources and asks you when they disagree rather than silently picking one.
