不同运动强度对肾脏影响 　 作者：罗仕云，方如美，陆恩峰，李国璋，李全岳，刘铁牛 【摘要】 目的 观察高强度运动与低强度运动对肾脏的不同影响。方法 将200名健康战士随机分两组，每组100名，高强度运动组进行3000m越野跑步，低强度运动组进行3000m步行，两组运动前均排尿并留取尿标本进行尿液分析，抽静脉血查血肌酐、尿素氮，运动后2h排尿、记尿量并留取尿标本进行尿液分析检查，抽静脉血查血肌酐、尿素氮。结果 两组运动前尿液分析均未见异常。高强度运动组运动后2h尿量显著少于低强度运动组（Plt;0.01）。高强度运动组运动后尿蛋白阳性率、血尿阳性率显著高于低强度运动组（P均lt;0.01）。但两组运动前、后血肌酐尿素氮无明显变化(Pgt;0.05）。结论 高强度运动后出现尿量减少，绝大多数参训者出现血尿、蛋白尿，提示高强度运动对肾脏有明显损害，而低强度的运动（步行）对肾脏无明显损害，因此慢性肾脏疾病患者不宜进行剧烈运动，而可进行低强度的运动康复锻炼。 【关键词】 运动试验；肾循环；尿量；蛋白尿；血尿 　　Abstract: Objective To investigate the effects of high-and low-intensity exercise on renal function. Methods 200 healthy soldiers participated in this study were randomly allocated to two groups, 100 in each group. The high-intensity exercise group ran 3000-metre running across the country, and the low-intensity exercise group walked 3000 metres. Before exercise test, the urine samples were collected and analyzed. The blood samples were collected for examining the indexes of creatinine, urea nitrogen. 2 hours after the exercises, the mentioned above laboratory tests were performed including recording the urine volume. Results Before exercise test, the urine analysis results for these two groups presented normal. After exercise, the urine volume in the high-intensity group were significantly lower, compared to the low-intensity group (Plt;0.01). And after exercise in the high-intensity group, the positive rates of proteinuria and hematuria were significantly higher, compared to the low-intensity group (Plt;0.01). But before and after exercise, the blood creatinine and urea nitrogen levels were almost the same (Pgt;0.05). Conclusion After high-intensity exercise, the participants’ urine volume decreased, and nematuria and proteinuria occurred in most of the participants indicated that high-intensity exercise might injure the renal function, and low-intensity exercise (walking) may be harmless to the kidney. Patients with chronic kidney disease are unfitable to do high-intensity exercise and be suitalbe for low-intensi
