[Purpose] This study sets out to investigate whether a short-term high-intensity arm ergometer exercise plan can be of benefit to adults whose poor ventilatory function places them at risk of developing chronic obstructive pulmonary disease. [Subjects and Methods] A pre-experimental design with a convenience sample was employed. The study enrolled 30 adult smokers, aged between 18-25 years old, all of whom were at a high risk of chronic obstructive pulmonary disease. The participants did a daily 20-minute high-intensity arm ergometer exercise, at 75% target heart rate, at the same time over a period of three days. The forced vital capacity test manoeuvre was carried out before the sessions, and once all three had been done. [Results] The study demonstrated a sizeable increase in the mean values of forced vital capacity and forced expiratory volume in one second. The mean values of expiratory volume in one second/forced vital capacity as well as peak expiratory flow rate were not significant statistically. [Conclusion] Although further studies, using larger sampling groups, need to be carried out, this research demonstrates that adults at high risk of chronic obstructive pulmonary disease improve lung function by following short-term high-intensity arm ergometer exercise.
[目的] 本研究旨在调查短期高强度手臂测力计运动计划是否对通气功能差、有患慢性阻塞性肺疾病风险的成年人有益。[对象与方法] 采用便利抽样的实验前设计。该研究招募了30名年龄在18至25岁之间的成年吸烟者，他们均有较高的慢性阻塞性肺疾病风险。参与者在三天内每天同时进行20分钟的高强度手臂测力计运动，运动强度为目标心率的75%。在运动前以及完成全部三次运动后进行用力肺活量测试操作。[结果] 研究表明，用力肺活量和一秒用力呼气量的平均值有显著增加。一秒呼气量/用力肺活量以及呼气峰值流速的平均值在统计学上无显著差异。[结论] 尽管需要使用更大的样本组进行进一步研究，但本研究表明，有慢性阻塞性肺疾病高风险的成年人通过进行短期高强度手臂测力计运动可改善肺功能。
