Results
Decreases in body weight and increases in hematocrit and hemoglobin concentration were significantly larger with overnight fasting than control conditions. Percentage changes in plasma volume were significantly larger with overnight fasting (-9.0%) than with the control protocol (-4.5%). Transfer function gain in the low-frequency range showed different changes between fasting and control conditions . The gain increased significantly with overnight fasting.
