Abstract
Background: Maintaining physical function is important for independence and frailty prevention in later life, but very few older adults meet exercise recommendations. Previous studies found that 4-week 'exercise and Tai-chi snacking' as a viable alternative to traditional exercise is acceptable to healthy older adults.
Objectives: This study aimed to investigate the effectiveness of a 12-week progressive exercise and Tai-chi snacking programme on physical function and psychological outcomes in pre-frail older adults.
Design: Randomised controlled trial.
Setting: Community-dwelling older adults.
Participants: 90 older adults with impaired strength and balance were recruited. Participants were randomly allocated to an intervention or waitlist control group.
Intervention: A 12-week progressive exercise and Tai-chi snacking programme.
Measurements: Physical function (the short physical performance battery (SPPB), single-leg balance test and sit-to-stand test) was remotely measured at participants' homes via video calls at baseline, 4-, 8-, and 12-weeks. The self-reported psychological outcomes were also assessed every 4 weeks using online questionnaires. A subset of 40 participants also completed in-person functional assessments, and 26 intervention participants underwent semi-structured interviews to feedback on their experiences.
Results: The 12-week progressive home-based exercise and Tai-chi snacking improved SPPB strength (estimated mean difference in week 4: 1.05; week 8: 0.79; and week 12: 0.79) and balance (estimated mean difference in week 4: 0.71; week 8: 0.57; and week 12: 0.65) at each timepoint compared to control group. Timed-up-and-go (estimated mean difference in week 4: 1.94; week 8: 1.58; and week 12: 1.1) and total SPPB scores (estimated mean difference in week 4: 2.24; week 8: 1.79; and week 12: 1.76) were also better in the intervention group compared to the control group in lab subset participants. Based on the qualitative findings, Participants found the programme accessible and beneficial, making it suitable for older adults and increasing self-efficacy in physical activities.
Conclusion: The home-based exercise and Tai-chi snacking programme significantly improved lower extremity strength, balance, and mobility in pre-frail older adults. This programme is considered to be a beneficial, acceptable and easy implemented physical function intervention.
期刊介绍:
The Journal of Frailty & Aging is a peer-reviewed international journal aimed at presenting articles that are related to research in the area of aging and age-related (sub)clinical conditions. In particular, the journal publishes high-quality papers describing and discussing social, biological, and clinical features underlying the onset and development of frailty in older persons. The Journal of Frailty & Aging is composed by five different sections: - Biology of frailty and aging In this section, the journal presents reports from preclinical studies and experiences focused at identifying, describing, and understanding the subclinical pathophysiological mechanisms at the basis of frailty and aging. - Physical frailty and age-related body composition modifications Studies exploring the physical and functional components of frailty are contained in this section. Moreover, since body composition plays a major role in determining physical frailty and, at the same time, represents the most evident feature of the aging process, special attention is given to studies focused on sarcopenia and obesity at older age. - Neurosciences of frailty and aging The section presents results from studies exploring the cognitive and neurological aspects of frailty and age-related conditions. In particular, papers on neurodegenerative conditions of advanced age are welcomed. - Frailty and aging in clinical practice and public health This journal’s section is devoted at presenting studies on clinical issues of frailty and age-related conditions. This multidisciplinary section particularly welcomes reports from clinicians coming from different backgrounds and specialties dealing with the heterogeneous clinical manifestations of advanced age. Moreover, this part of the journal also contains reports on frailty- and age-related social and public health issues. - Clinical trials and therapeutics This final section contains all the manuscripts presenting data on (pharmacological and non-pharmacological) interventions aimed at preventing, delaying, or treating frailty and age-related conditions.The Journal of Frailty & Aging is a quarterly publication of original papers, review articles, case reports, controversies, letters to the Editor, and book reviews. Manuscripts will be evaluated by the editorial staff and, if suitable, by expert reviewers assigned by the editors. The journal particularly welcomes papers by researchers from different backgrounds and specialities who may want to share their views and experiences on the common themes of frailty and aging.The abstracting and indexing of the Journal of Frailty & Aging is covered by MEDLINE (approval by the National Library of Medicine in February 2016).
