| REEFFM (kJ day−1) | 6274 ± 226 | 6414 ± 256 | 6289 ± 285 | 0.51 |
 (ml kg−1 min−1) |
34.8 ± 3.1 | 42.7 ± 4.6 | 42.4 ± 5.0 | 0.25 |
| HRpeak (beats min−1) | 187 ± 3 | 185 ± 3 | 187 ± 4 | 0.87 |
| RERpeak | 1.17 ± 0.03 | 1.19 ± 0.04 | 1.20 ± 0.04 | 0.87 |
Data are mean ±s.e.m. BMI, body mass index; REEFFM, resting energy expenditure adjusted for fat-free mass; HRpeak, peak heart rate; 
, peak oxygen uptake; RERpeak, peak respiratory exchange ratio.
