ENERGY AND WATER METABOLISM, BODY COMPOSITION, AND HORMONAL CHANGES INDUCED BY 42 DAYS OF ENFORCED INACTIVITY AND SIMULATED WEIGHTLESSNESS.
Inactivity causes profound deleterious changes. We investigated in eight healthy men the impact of a 42-day head-down bed rest (HDBR) on energy and water metabolism and their interrelationships with body composition (BC) and catabolic and anabolic hormones. Total energy expenditure (TEE), total body water, water turnover, and metabolic water formation were assessed by the doubly [...]
