Renal, Metabolic, and Circulatory Responses to Heat and Exercise

Acute renal failure is known to occur in military recruits during summer basic training. The effect of these summer training exercises on the urinary sediment, renal excretion of heme pigments, renal concentrating mechanism, body temperature, muscle enzymes, serum uric acid, coagulation factors, and systemic hemodynamics was evaluated during both the early and late stages of basic training. The findings are discussed in the context of potential predisposing and precipitating causes of acute renal failure, and a pathogenetic schema is proposed.
