目的：这项试点研究的目的是评估久坐行为（SB）减少干预（跺脚（延长）坐（SOS））在体弱的老年adultes.METHODS的效果：参与者（> 65岁）从庇护住宅区招募，并随机分为2组。在第2、6和10周，两组都进行了面对面的40分钟激励会议，包括对身体功能和SB的反馈。一组增加了对坐姿的实时触觉反馈。通过activPAL记录总的久坐时间和SB模式，沿着经验证的功能测量：定时起身和行走（TUG）、坐立（STS）和平衡测试。结果：23名参与者开始SOS干预。健康问题导致这一脆弱人群的高损耗。两组的TUG（快4秒）和STS（30秒内上升>2）评分均显著改善。SB参数无显著变化。结论：动机访谈功能测试反馈，视觉和实时反馈SB改善身体功能的研究。这项试点研究表明，从坐到站的过渡可以打破长时间的坐姿，这可能有助于减少那些经常无法进行更激烈的运动干预的人的虚弱和功能下降。
OBJECTIVES: This pilot study aimed to evaluate the effect of a sedentary behaviour (SB) reduction intervention (Stomp Out (Prolonged) Sitting (SOS)) in frail older adults.METHODS: Participants (>65years) were recruited from sheltered housing complexes and randomized into 2 groups. On weeks 2, 6 and 10 both groups had face-to-face 40min motivational sessions, including feedback on physical function and SB. One group had the addition of real-time tactile feedback on sitting. Total sedentary time and patterns of SB were recorded by activPAL, along with validated measures of function: Timed Up and Go (TUG), Sit-to-Stand (STS) and balance tests. Outcomes were analyzed by intention-to-treat mixed model analysis.RESULTS: Twenty-three participants started the SOS intervention. Health issues led to high attrition in this frail population. TUG (4 seconds faster) and STS (>2 rises more in 30 seconds) scores improved significantly in both groups. There were no significant changes in SB parameters.CONCLUSION: Motivational interviewing alongside functional test feedback, visual and real-time feedback on SB improved physical function over the study. This pilot study suggests that sit-to-stand transitions to break prolonged sitting time may help reduce frailty and functional decline in people who are often unable to engage in more intense exercise interventions.
