Heart rate variability
The clearest read on parasympathetic tone. Captured from a 60-second face scan and from wearables, so trends hold up night to night.
What we measure
The autonomic signals that decide your day
The autonomic nervous system sets recovery, readiness and how much load you can absorb. Most programmes guess at it. We measure it remotely, every day, so you can train against what changes.
Resting and recovery heart rate
How quickly the system returns to baseline after load — the difference between training hard and training well.
Respiration and breath control
Breathing rate and pattern shape autonomic state directly, and they respond to practice faster than almost any other signal.
Reaction time and attention
Timed cognitive tasks show when fatigue has reached the brain, often before it shows up in the legs.
Sleep regularity
Consistent timing does more for autonomic recovery than total hours alone. We track both and weight the one that moves.
Stress and load balance
Training load set against measured recovery, so the next block is planned on evidence instead of feel.
The team
Measurement your team can use
BRAIN.ONE supplies the measurement. You work it with your own coach or performance team, planning around the nervous system rather than around the calendar.
Built for your coach
Measured autonomic data your own coach or performance team can plan against, instead of generic templates.
Nervous-system focus
The measurement covers the nervous system side of performance — breath, sleep, parasympathetic load and return to baseline.
Measurement built in
Every recommendation maps back to a signal we track, and every four weeks we show whether it moved.
How it runs
Measure. Coach. Re-measure.
- 01
Baseline
A face scan, timed cognitive tasks and wearable history establish your autonomic starting point.
- 02
Daily protocol
You get a daily protocol built around the signals that are actually limiting you — breathwork, load placement, sleep timing, recovery work — to run on your own or with your coach or team.
- 03
Daily check-in
Fifteen minutes a day, entirely remote. Readiness is read each morning and the day adapts to it.
- 04
Re-measure
The same instruments repeat every four weeks, so change is a within-person trend line, not a feeling.
