Abstract

While the positive effects of exercise on frailty are well documented, the effect of exercise on quality of life (QoL) and activities of daily living (ADL) in frail older adults remains less certain. Therefore, this paper aimed to systematically review the literature investigating the effect of exercise on QoL and ADL in this group. Embase, MEDLINE, CENTRAL, PEDro and Web of Science Core Collections were searched systematically using relevant MeSH terms. The inclusion criteria were: controlled trial design, published in English, population included frail older adults, frailty measured quantitatively, interventions that included exercise, and QoL or ADL measurements (PROSPERO: CRD42018106173). After screening, 15 studies were eligible for inclusion in the qualitative synthesis (total n: 2467; mean age range: 70–85 years). There was a positive effect on QoL or ADL measures in 10 out of the 15 studies. QoL and ADLs only improved in studies that also reported improved physical outcomes. These results reflect the multi-factoral nature of frailty and how physical capability and QoL are interlinked. Heterogeneity precluded formal meta-analysis. Future trials in frail older adults should focus on interventions that include exercise, measure physical outcomes and use consistent study design to enable meta-analysis to be conducted.
