| Trunk BF % | 1.294 (0.706) | −0.365 (0.826) | −2.984, 1.615 |
| Trunk body weight | −0.478 (0.688) | 0.575 (0.837) | −1.671, 0.707 |
| PEF | 28.463 (28.137) | 0.009 (0.020) | −0.887, 1.764 |
| PIF | −28.777 (20.321) | 0.030 (0.028) | −3.337, 0.681 |
| Respiratory muscle strength | −12.145 (6.241) | −0.058 (0.090) | −1.371, 3.369 |
Data are expressed as coefficient (standard error). All mediation analyses were performed using the complete sample (N = 43). N3, NREM sleep stage 3; PEF, peak expiratory flow; PIF, peak inspiratory flow.
