[Purpose] The associations between respiratory function, physical performance, physical activity, and sedentary behavior in older adults remain to be elucidated. This study aimed to investigate the associations of lung volume and respiratory muscle strength with physical performance, physical activity, and sedentary behavior in older adults. [Participants and Methods] In 62 ambulatory community-dwelling older adults, lung volumes (forced vital capacity and forced expiratory volume in 1s), respiratory muscle strength (maximum inspiratory and expiratory muscle pressures), physical performance (Timed Up and Go test and 30 s chair stand test), physical activity (steps and locomotive and non-locomotive physical activity), and sedentary behavior (percent sedentary time) were assessed. [Results] The percent sedentary time, 30-s chair stand test performance, and non-locomotive moderate-to-vigorous physical activity were independently associated with forced vital capacity, maximum inspiratory pressure, and maximum expiratory pressure, respectively. [Conclusion] The preliminary findings suggest that lung volumes and respiratory muscle strength may be differently affected by physical performance, physical activity, and sedentary behavior in ambulatory older adults.
[目的] 老年人的呼吸功能、身体机能、身体活动和久坐行为之间的关联尚待阐明。本研究旨在调查老年人的肺容量和呼吸肌力量与身体机能、身体活动和久坐行为之间的关联。[参与者与方法] 对62名社区居住的能独立行走的老年人进行了评估，测量指标包括肺容量（用力肺活量和1秒用力呼气量）、呼吸肌力量（最大吸气和呼气肌压力）、身体机能（计时起立行走测试和30秒坐立试验）、身体活动（步数以及移动和非移动身体活动）以及久坐行为（久坐时间百分比）。[结果] 久坐时间百分比、30秒坐立试验表现和非移动中等到剧烈身体活动分别与用力肺活量、最大吸气压力和最大呼气压力独立相关。[结论] 初步研究结果表明，在能独立行走的老年人中，身体机能、身体活动和久坐行为可能对肺容量和呼吸肌力量产生不同的影响。
