摘　　要：目的:探索中等强度有氧运动对慢性肾病患者(chronic kidney disease,CKD)峰值摄氧量和无氧阈的影响,测定以峰值摄氧量百分数表示的无氧阈值(anaerobic threshold,AT)强度,为慢性肾病患者的临床康复运动方案提供依据。方法:70例CKD患者随机分为对照组(n=35)、运动组(n=35)。运动组以50%峰值摄氧量(peak oxygen uptake,VO_(2peak))踏功率自行车,每次30min,每周3次,共12周。12周训练前后,所有患者进行心肺运动试验(cardiopulmonary exercise test,CPET),测定受试者的峰值摄氧量(VO_(2peak)),同时利用简化V-slope法判定每位患者无氧阈值。结果:训练前两组VO_(2peak)、AT以及AT占VO_(2peak)百分比均无明显差异(P>0.05);训练后,与对照组相比,运动组的VO_(2peak)、AT以及AT占VO_(2peak)百分比均有显著改善(P<0.05)。结论:中等强度的有氧运动对CKD患者VO_(2peak)、AT有改善作用。CKD患者以%VO_(2peak)表示的AT值(73.50±1.31%VO_(2peak))高于未经训练的健康人群(50%—60%VO_(2peak))。Objective：To observe the effects of moderate intensity aerobic training on peak oxygen uptake（VO2peak） and anaerobic threshold（AT） in patients with chronic kidney disease（CKD）. Method： Seventy patients with chronic kidney disease were divided into control group （n=35） and training group （n=35）. Training group performed cycle ergometer at 50%VO2peak for 30 min per time, 3 times every week for 12 weeks. All patients were evaluated VO2peak by cardiopulmonary exercise test（CPET）. The AT was determined using simplified V-slope. Result： There was no significant difference （P〉0.05） in all variables between two groups before training. After training, the VO2peak, AT, AT/VO2peak percentage of training group was significantly different with control group （P〈0.05）. Conclusion： The moderate intensity aerobic training can improve VO2peak and AT in patients with chronic kidney disease. Meanwhile, the AT/VO2peak percentage in CKD patients（73.50±1.31%） is higher than untrained but healthy individuals（50%—60%） after trainning.
