ABSTRACT

Objective To investigate the incidence of renal injury caused by strong intensity military training in the navy.Methods One thousand three hundred and twenty servicemen of the navy were enrolled in the present study including 568 recruits and 752 veterans.Urine protein and hemoglobin were determined using the dry chemistry method after a five-kilometer armed field race.Urine samples were collected and centrifuged for erythrocyte count under microscope after training.Retinol binding protein(RBP) and N-acetyl-?-D-glucosaminidase(NAG) were measured by enzyme linked immunosorbent assay(ELISA).Detection of creatine kinase(CK) above 950U/L was assumed to be rhabdomyolysis positive.Results The average incidence of hematuria,hemoglobinuria and proteinuria was 2.1%,7.4% and 44 %,respectively,and the incidence of abnormal RBP and NAG was 57.3% and 57.1%,respectively.Significant difference in each of the indexes existed between the recruits and veterans(P
