# Type Alias: PowerZone

> **PowerZone** = `1` | `2` | `3` | `4` | `5` | `6` | `7`

Defined in: [packages/core/src/domain/zones/power-zones.ts:18](https://github.com/pablo-albaladejo/kaiord/blob/3eacbe62ef72342d970523967cc5155b5935bb85/packages/core/src/domain/zones/power-zones.ts#L18)

Coggan 7-band power-zone-to-percent-FTP table.

Single source of truth for translating a discrete cycling power zone
(1..7) into the percent-of-FTP value the zone represents. Lives in the
domain layer because the mapping is a fitness-domain truth (Coggan
power-zone definitions), not a format encoding.

Zone 1 (Recovery):       55% FTP
Zone 2 (Endurance):      75% FTP
Zone 3 (Tempo):          90% FTP
Zone 4 (Threshold):     105% FTP
Zone 5 (VO2 Max):       120% FTP
Zone 6 (Anaerobic):     150% FTP
Zone 7 (Neuromuscular): 200% FTP
