Exercise test variables (medians and quartiles)
| CFS (n = 23) | Control (n = 20) | P‐value | |
|---|---|---|---|
| RPE score at HR 70% peak | 15 (14, 18) | 13 (12, 13) | P = 0·002 |
| RPE > median of 14 at HR 70% peak | 16 (70%) | 4 (20%) | P = 0·001 |
| Time on bike (s) | 960 (675, 1530) | 1530 (1080, 1620) | P = 0·027 |
| V·O2 peak (ml/kg/min−1) | 20·4 (16·8–22·2) | 19·5 (14·1–21·2) | P = 0·31 |
| Peak HR (b/min−1) | 143 (136–154) | 151 (145–159) | P = 0·09 |
| Max power (watts) | 90 (60–90) | 90 (60–90) | P = 0·62 |
| Competed test (yes) | 9 (39%) | 14 (70%) | P = 0·043 |
RPE = rating of perceived exertion; HR = heart rate; V·O2 = volume of oxygen; CFS = chronic fatigue syndrome.
