Thresholds for endurance and strength exercise group allocations based on maximum exercise capacity
| Exercise training level | Thresholds for endurance exercise group allocation based on percentage of normal V̇O2 peak (%) | Thresholds for strength exercise group allocation based on relative V̇O2 peak (mL/min/kg) |
| 1 | ≤75.0 | ≤16.0 |
| 2 | 75.1–90.0 | 16.1–22.0 |
| 3 | 90.1–110.0 | 22.1–30.0 |
| 4 | >110.0 | >30.0 |
V̇O2peak: peak oxygen uptake.
