Backward method multiple-linear-regression analysis of the associations of body water with significant predictor variables in male swimmers (n = 27).
| β | SE | P | Adjusted R2 | |
|---|---|---|---|---|
| 1Total body water (L) | .77 | |||
| DXA Lean mass (g) | .88 | .00 | .00 | |
| 2Intracellular water (L) | .58 | |||
| DXA Lean mass (g) | .91 | .00 | .00 | |
| DXA Fat mass (g) | -.30 | .00 | .06 | |
| 3Extracellular water (L) | .85 | |||
| DXA Lean mass (g) | .93 | .00 | .00 |
1. Total body water model: F1,26 = 85.7, p < 0.00; Fat mass and bone mineral content were not significant predictors in this model.
2. Intracellular water model: F2,26 = 18.9, p < 0.00; Bone mineral content was not a significant predictor in this model.
3. Extracellular water model: F1,26 = 150.6, p < 0.00; Fat mass and bone mineral content were not significant predictors in this model.
