Abstract

Introduction: Reduced physical activity and prolonged sedentary behavior (SB) are associated with poor prognosis in patients undergoing hemodialysis. Although intradialytic exercise training (IET) is increasingly implemented, its effect on SB remains unclear. This study compared the effects of IET and cognitive training on SB.

Methods: In this multicenter pilot crossover study, patients aged 70-80 years undergoing maintenance hemodialysis completed 12 weeks of IET and 12 weeks of intradialytic cognitive training, separated by a 2-week washout period. Sedentary time (≤ 1.5 METs) and step counts were assessed using an accelerometer before and after each intervention.

Results: Nine participants completed the study. IET significantly reduced SB on all days and non-dialysis days (p = 0.02), whereas cognitive training showed no significant change. Reductions were significantly greater following IET. Step counts did not change.

Conclusion: IET reduced SB, whereas cognitive training did not, suggesting its clinical relevance in dialysis care.

血液透析患者的透析内运动训练与认知训练相比减少久坐行为：一项初步研究。

血液透析患者体力活动减少和久坐行为（SB）延长与预后不良相关。尽管分析性运动训练（IET）越来越多地被应用，但其对SB的影响尚不清楚。该研究比较了IET和认知训练对sbs的影响。方法：在这项多中心先导交叉研究中，70-80岁接受维持性血液透析的患者完成了12周的IET和12周的透析内认知训练，中间间隔2周的洗脱期。在每次干预前后使用加速度计评估久坐时间（≤1.5 METs）和步数。结果：9名参与者完成了研究。IET在所有日和非透析日均显著降低SB (p = 0.02)，而认知训练无显著变化。IET后的降幅明显更大。步数没有改变。结论：IET降低了SB，而认知训练没有，提示其在透析护理中的临床意义。
