Abstract: Objective To investigate the influence of different years of military service and training fields on the incidence of non-traumatic renal injury due to high intensity military training. Methods A total of 1 320 officers and men from marines were enrolled in the present study.Proteinuria and hemoglobinuria were detected by dry chemistry test strips after five-kilometer armed cross-country race.Positive hematuria was observed under microscope after centrifugation of urine samples.Retinol-binding protein（RBP）and N-acetyl-β-D-glucosaminidase（NAG）were detected by enzyme linked immunosorbent assay（ELISA）.The results obtained from the officers and men of marines were compared and analyzed. Results The incidence rate of hematuria,proteinuria,hemoglobinuria,NAG,and RBP was 2.1%,7.4%,44%,57.1%,and 57.3%,respectively.There was a difference in the incidence rate of the above abnormalities between those with less than 1 year of military service and those with more than 1 year of military service（P＜0.05）,but no difference between those with more than 1 year of military service（P＞0.05）.The incidence of NAG and RBP was significantly different between those after training in different fields（P＜0.05）. Conclusion The incidence of renal injury high intensity military training is relatively high and correlates to different years of military service and training fields.
