Limited mobility in older adults consistently predicts both morbidity and mortality. As individuals age, the rates of mobility disability increase from 1.0% in people aged 15-24 to 20.6% in adults over 65 years of age. Physical activity can effectively improve mobility in older adults, yet many older adults do not engage in sufficient physical activity. Evidence shows that increasing physical activity by 50 min of moderate intensity physical activity in sedentary older adults with mobility limitations can improve mobility and reduce the incidence of mobility disability. To maximize the healthy life span of older adults, it is necessary to find effective and efficient interventions that can be delivered widely to prevent mobility limitations, increase physical activity participation, and improve quality of life in older adults. We propose a randomized controlled trial to assess the effect of a physical activity health coaching intervention on mobility in older adults with mobility limitations.
This randomized controlled trial among 290 (145 per group) community-dwelling older adults with mobility limitations, aged 70-89 years old, will compare the effect of a physical activity health coaching intervention versus a general healthy aging education program on mobility, as assessed with the Short Physical Performance Battery. The physical activity health coaching intervention will be delivered by exercise individuals who are trained in Brief Action Planning. The coaches will use evidence-based behavior change techniques including goal-setting, action planning, self-monitoring, and feedback to improve participation in physical activity by a known dose of 50 min per week. There will be a total of 9 health coaching or education sessions delivered over 26 weeks with a subsequent 26-week follow-up period, wherein both groups will receive the same duration and frequency of study visits and activities.
The consequences of limited mobility pose a significant burden on the quality of life of older adults. Our trial is novel in that it investigates implementing a dose of physical activity that is known to improve mobility in older adults utilizing a health coaching intervention.

老年人活动能力受限始终会预测发病率和死亡率。随着年龄的增长，行动障碍的发病率从 15-24 岁人群的 1.0%上升到 65 岁以上人群的 20.6%。身体活动可以有效地改善老年人的活动能力，但许多老年人没有进行足够的身体活动。有证据表明，对于行动受限的久坐老年人，将身体活动量增加 50 分钟中等强度的身体活动，可改善活动能力并降低行动障碍的发生率。为了最大限度地延长老年人的健康寿命，有必要找到可以广泛推广的有效且高效的干预措施，以预防活动受限，增加身体活动参与度，并改善老年人的生活质量。我们提出了一项随机对照试验，以评估身体活动健康教练干预对行动受限的老年患者活动能力的影响。
这项在 290 名（每组 145 名）社区居住的、有行动受限的 70-89 岁老年人中进行的随机对照试验，将比较身体活动健康教练干预与一般健康老龄化教育计划对活动能力的影响，评估工具为简短身体表现电池测试。身体活动健康教练干预将由经过简短行动计划培训的运动个体来实施。教练将使用基于证据的行为改变技术，包括设定目标、行动计划、自我监测和反馈，以提高每周 50 分钟的身体活动参与度。共将进行 9 次健康教练或教育会议，历时 26 周，并在随后的 26 周随访期间，两组都将接受相同时间和频率的研究访问和活动。
活动能力受限的后果对老年人的生活质量造成了重大负担。我们的试验是新颖的，因为它研究了利用健康教练干预来实施已知可改善老年人活动能力的身体活动剂量。
