Pulmonary Rehabilitation (PR) increases exercise capacity, with less clear evidence regarding physical activity (PA). The World Health Organization recommends at least 150-300 minutes of moderate-intensity or 75-150 minutes of vigorous-intensity aerobic PA per week to reduce the risks of chronic disease.
The objective of this study was to assess the effectiveness of conventional PR versus web-based PR with respect to changes in PA.
Patients with COPD were randomized to either conventional PR classes (n=51) or a web-based PR program (n=52) for 7 weeks in a feasibility study. Accelerometers (Sensewear) were worn before and after the intervention, and PA was measured as steps per day and mean bouts of moderate activity for ≥2, ≥5, ≥10, and ≥20 minutes. Measures were derived for patients with ≥8 hours of data per day for ≥4 days, using the R package for statistical analysis. Variables were explored to examine their relationships with bouts of activity.
Baseline characteristics did not differ significantly between groups. Complete PA data were available for the groups receiving web-based (n=20) and conventional (n=34) PR interventions. The web-based PR group demonstrated a nonsignificant increase in the number of steps per day, which mainly comprised short bouts of moderate to vigorous intensity PA when compared to the conventional PR group (P=.20). The conventional PR group demonstrated increased 20-minute bouts of PA by 49.1%, although this was not significant (P=.07). At baseline, age (r=-0.21, P=.04), BMI (r=-0.311, P=.004), and FEV (forced expiratory volume in 1 second; % predicted; r=-0.248, P=.048) were significantly correlated with 10-minute bouts of PA; however, this was not observed post intervention.
The analysis revealed a nonsignificant difference in the pattern of PA between groups receiving conventional vs web-based PR-the former being associated with an increase in 20-minute bouts, while the latter having demonstrated an increase in the number of steps per day. There appears to be a differing response emerging between the two interventions.

肺康复（PR）可提高运动能力，但关于身体活动（PA）的证据尚不明确。世界卫生组织建议每周至少进行150 - 300分钟中等强度或75 - 150分钟高强度有氧运动，以降低慢性病风险。
本研究旨在评估传统PR与基于网络的PR对PA变化的有效性。
在一项可行性研究中，慢性阻塞性肺疾病（COPD）患者被随机分为传统PR课程组（n = 51）或基于网络的PR项目组（n = 52），为期7周。在干预前后佩戴加速度计（Sensewear），PA以每日步数以及持续≥2、≥5、≥10和≥20分钟的中等强度活动的平均次数来衡量。对于每天有≥8小时数据且持续≥4天的患者，使用R软件包进行统计分析得出测量结果。探索变量以检查它们与活动次数的关系。
两组的基线特征无显著差异。接受基于网络（n = 20）和传统（n = 34）PR干预的组可获得完整的PA数据。与传统PR组相比，基于网络的PR组每日步数有不显著增加，且主要由短时间的中高强度PA组成（P = 0.20）。传统PR组持续20分钟的PA次数增加了49.1%，尽管这并不显著（P = 0.07）。在基线时，年龄（r = -0.21，P = 0.04）、体重指数（BMI；r = -0.311，P = 0.004）和第1秒用力呼气量（FEV；预测值%；r = -0.248，P = 0.048）与持续10分钟的PA显著相关；然而，干预后未观察到这种情况。
分析显示，接受传统PR与基于网络的PR的组之间，PA模式存在不显著差异——前者与持续20分钟的活动次数增加有关，而后者则表现为每日步数增加。两种干预措施之间似乎出现了不同的反应。
