Physical exercise is a potential intervention to revert or attenuate frailty syndrome, which may be accomplished by traditional center-based and home-based programs. This study aimed to compare the effectiveness of a home-based and center-based exercise program on frailty status, physical and muscle function of frail older women. Thirty-one frail older women were allocated in two different groups: home-based group (n = 17, 71.5 ± 6.5 years) or center-based group (n = 14, 68.4 ± 6.4 years). The exercise program lasted 12 weeks (3 days/week), 60 minutes/session, including strengthening, balance, and gait exercises. Frailty status, knee, and hip strength, and physical function were assessed before and after the intervention. After the exercise program, frailty was reversed in 76% of the participants independently of the exercise group. Muscle strength and physical function improved in both groups, where the home-based program presented a high adherence rate, and the center-based program was more suitable to reverse the frailty status. In conclusion, a home-based exercise program is as effective as center based to improve strength, physical function, and to reverse frailty status.

居家锻炼能否改善体弱前老年女性的身体机能？

体育锻炼是一种潜在的干预措施，可以逆转或减轻虚弱综合征，这可以通过传统的中心和家庭计划来完成。本研究旨在比较以家庭为基础和以中心为基础的锻炼计划对虚弱老年妇女的虚弱状态、身体和肌肉功能的有效性。31 名体弱的老年妇女被分为两个不同的组：家庭组（n  = 17, 71.5 ± 6.5 岁）或中心组（n = 14, 68.4 ± 6.4 岁）。锻炼计划持续了 12 周（3 天/周），每次 60 分钟，包括加强、平衡和步态练习。在干预前后评估虚弱状态、膝关节和髋关节力量以及身体功能。在锻炼计划之后，独立于锻炼组的参与者中有 76% 的虚弱得到了逆转。两组的肌肉力量和身体机能都有所改善，其中以家庭为基础的计划呈现出较高的依从率，而以中心为基础的计划更适合扭转虚弱状态。总而言之，家庭锻炼计划与以中心为基础的锻炼计划一样有效，可提高力量、身体机能和扭转虚弱状态。
