A metered intake of milk following exercise and thermal dehydration restores whole-body net fluid balance better than a carbohydrate-electrolyte solution or water in healthy young men.

摘要: Appropriate rehydration and nutrient intake in recovery is a key component of exercise performance. This study investigated whether the body net fluid balance (NFB) following thermal dehydration to -2 % mass (BM) was enhanced by metered rate ingestion milk (M) compared with carbohydrate-electrolyte solution (CE) or water (W). In randomised order, seven active men (aged 26·2 (sd 6·1) years) undertook BM on three occasions. A replacement volume M, CE W equivalent 150 loss then consumed within 2-3 h. NFB subsequently measured for 5 h from commencement rehydration. higher overall M than (P=0·001) (P=0·006) observed, no difference between (P=0·69). After h, remained positive (+117 122) ml) basal, it greater (-539 390) ml, P=0·011) but not (-381 460) P=0·077, d=1·6). Plasma osmolality (Posm) K elevated above basal W. The change Posm associated circulating pre-provasopressin (r s 0·348, P<0·001), biomarker arginine vasopressin, could account fully augmented These data suggest that approach acts synergy composition restoration dehydration.
