Extracellular water-to-total body water ratio

1. Exercise decreases extracellular water-to-total body water ratio in humans (-0.15 percentage points (95% CI -0.22 to -0.07)).

   “engaging in 150 to 299 min/week and ≥300 min/week of MVPA was associated with -0.11 (95% CI -0.19 to -0.03) and -0.15 (95% CI -0.22 to -0.07) percentage points lower ECW-to-TBW ratio, respectively.”
