Abstract：
BACKGROUND: The coronavirus disease 2019 (COVID-19) pandemic and lockdown reduced physical activity levels in hemodialysis (HD) patients and kidney transplant recipients (KTRs). This study aimed to describe physical activity levels during lockdown and assess the effects of an online home-based exercise training program on physical activity levels in HD patients and KTRs.
METHODS: Forty-five HD patients and thirty-five KTRs were divided into four groups: exercise groups 1 (ΕΧ-HD) and 2 (EX-KTR) followed a 4-month tele-exercise training program, while control groups received usual care. All participants at baseline and at the end of the study completed the International Physical Activity Questionnaire (IPAQ), while their daily physical activity levels were recorded via a step counting application.
RESULTS: At the end of the study, the repeated measures analysis revealed a significant effect of time, group, and time-by-group interaction in the average steps per day, walking, and moderate activity for the exercise-HD group (p < 0.05). Similarly, the analysis revealed a notable effect of time, group, and time-by-group interaction in the exercise-KTR group in average daily steps, vigorous and walking activity (p < 0.05). Multiple regression analysis showed that the level of physical activity at the end of the study was related to the urban place of residence and the participation in the 4-month exercise program of both HD patients and KTRs.
CONCLUSIONS: Participation in a tele-exercise training program led to favorable effects on physical activity levels both in HD patients and KTRs during lockdown.

摘要：
背景：2019年冠状病毒病（COVID-19）大流行和封锁降低了血液透析（HD）患者和肾移植受者（KTR）的身体活动水平。这项研究旨在描述封锁期间的身体活动水平，并评估在线家庭运动训练计划对HD患者和KTR身体活动水平的影响。
方法：将45名HD患者和35名KTR患者分为四组：运动组1（EX-HD）和运动组2（EX-KTR），然后进行为期4个月的远程运动训练计划，对照组接受常规护理。所有参与者在基线和研究结束时都完成了国际身体活动问卷（IPAQ），而他们的日常体力活动水平是通过计步应用程序记录的。
结果：在研究结束时，重复测量分析揭示了时间的显著影响，group,以及每天平均步数的分组互动，走路,运动-HD组活动适中（p<0.05）。同样，分析揭示了时间的显著影响，group,在运动-KTR组中，以平均每日步数进行分组时间互动，活力和步行活动(p<0.05)。多元回归分析显示，研究结束时的身体活动水平与城市居住地以及HD患者和KTRs参加4个月运动计划有关。
结论：在封锁期间，参加远程运动训练计划对HD患者和KTR的身体活动水平均产生了有利的影响。
