Supervised exercise has shown benefits for subjects with asthma, but little is known about the effectiveness of unsupervised physical activity on this population. We investigated the effects of a 12-week unsupervised pedometer-based physical activity program on daily steps and on clinical and psychological parameters of adults with asthma. Clinically stable adults with moderate to severe asthma were encouraged to take daily 30-minute walks and were randomized to pedometer and control groups. The pedometer group received pedometers and individualized daily step targets. Changes in daily steps (average of steps taken during six consecutive days), six-minute walk test (6MWT), health-related quality of life, asthma control and anxiety and depression levels were assessed 12 weeks after intervention and 24-28 weeks after randomization. Thirty-seven participants were recruited and 30 completed the intervention. At 12 weeks, the groups differed significantly in daily steps (adjusted average difference, 2488 steps; 95% confidence interval [CI], 803 to 4172; p = 0.005) and in the 6MWT (adjusted average difference, 21.9 m; 95% CI, 6.6 to 37.3; p = 0.006). These differences were not significant 24-28 weeks after randomization. The program was effective in increasing daily steps of adults with moderate to severe asthma 12 weeks after intervention.
有监督的运动已显示出对哮喘患者有益，但对于无监督的体育活动对该人群的有效性知之甚少。我们调查了一项基于计步器的为期12周的无监督体育活动计划对哮喘成人每日步数以及临床和心理参数的影响。鼓励临床病情稳定的中度至重度哮喘成人每天进行30分钟的步行，并随机分为计步器组和对照组。计步器组收到计步器和个性化的每日步数目标。在干预12周后以及随机分组24 - 28周后，评估每日步数（连续六天所走步数的平均值）、六分钟步行试验（6MWT）、健康相关生活质量、哮喘控制以及焦虑和抑郁水平的变化。招募了37名参与者，30名完成了干预。在12周时，两组在每日步数（调整后的平均差异为2488步；95%置信区间[CI]，803至4172；p = 0.005）和6MWT（调整后的平均差异为21.9米；95%CI，6.6至37.3；p = 0.006）方面存在显著差异。在随机分组24 - 28周后，这些差异不显著。该计划在干预12周后有效增加了中度至重度哮喘成人的每日步数。
