Differences in function and body composition between HF patients and control subjects.
| HF | Controls | Significance | |
|---|---|---|---|
| Aerobic capacity | |||
| Peak VO2 (ml‧kg−1‧min−1) | 15.4±4.2 | 23.4±6.6 | <0.0001 |
| VAT (ml‧kg−1‧min−1) | 10.9±2.1 | 14.4±4.0 | <0.0001 |
| VE/VCO2 slope | 35.7±10.6 | 29.1±4.6 | <0.01 |
| Strength capacity | |||
| 1RM (kg) | 154.8±52.0 | 195.3±56.8 | <0.01 |
| Power (watts) | 226.4±99.2 | 313.3±130.6 | <0.01 |
| DXA fat and lean body mass distributions (normalized to height) | |||
| Total lean (kg) | 31.2±4.8 | 32.5±3.8 | 0.20 |
| Legs lean (kg) | 10.3±2.0 | 11.1±1.4 | <0.05 |
| Arms lean (kg) | 3.8±0.7 | 4.0±0.9 | 0.24 |
| Total fat (kg) | 16.7±9.4 | 16.3±5.0 | 0.82 |
| Leg fat (kg) | 4.6±2.8 | 4.3±1.4 | 0.62 |
| Arm fat (kg) | 1.6±.9 | 1.6±0.6 | 0.80 |
Peak VO2 indicatesmaximal oxygen consumption; VAT oxygen consumption at anaerobic threshold; VE/VCO2 slope ventilatory efficiency; 1RM the one repetition maximum.
