Abstract:
Objective To investigate the effect of high intensity military training in the high temperature and high humidity environment on the lesion of the kidney tissue and to provide evidence for the prevention and treatment of kidney lesion induced by high intensity training in the high temperature and high humidity environment.Methods Four hundred officers and men from the reef - garrison units were divided in accordance with their enrollment and training environment into 4 groups,i.e.the high temperature and high humidity recruit group,the high temperature and high humidity veteran group,the normal temperature and normal humidity recruit group and the normal temperature and normal humidity veteran group,and received 10 km fully-armed field training.Urine samples were collected before and after training for routine check.Retinol binding protein (RBP) and N-acetyl-β-D-glucosaminidase (NAG) were detected with ELISA.Venous blood was collected to detect the levels of creatinine (CR) and blood urea nitrogen (BUN),and the obtained results were used for statistical analysis.Results Urine output of the high temperature and high humidity recruit group after training was (25.2 ± 8.5) ml,which was obviously lower than that of the other 3 groups,with statistical significance (P ＜ 0.05 ).The positive rates of hematuria,hemoglobinuria and proteinuria were 13％,17％ and 68％ respectively.The abnormal rates of NAG/Cr and RBP were 84％ and 89％ respectively,which were obviously higher than those of the other 3 groups,also with statistical significance ( P ＜ 0.05 ).However,no significant changes could be detected in serum creatinine and blood urea nitrogen for all the 4 groups both before and after training (P ＞ 0.05 ).Conclusions Intense military training in the high temperature and high humidity environment could induce certain kidney lesion,especially to recruits.Veterans displayed better heat tolerance and adaptability.
