Objectives:
The study aimed to carry out a systematic review and meta-analysis to explore the effects of multicomponent exercise on frailty status and physical function in frail older adults.
Design:
A systematic review and meta-analysis.
Setting And Participants:
Older adults aged ≥60 years diagnosed with frailty using the Frailty Assessment Tool.
Methods:
PubMed, EMBASE, Web of Science, Cochrane Library, CNKI, and Wanfang were searched from inception to March 10, 2024. Two reviewers independently screened and selected the publications, extracted the data, and assessed risk of bias. This study included randomized controlled trials and quasi-experimental designs. Review Manager 5.4 was used for data analysis.
Results:
Twenty-eight randomized controlled trials with 4857 older adults were included. Multicomponent exercise significantly improved frailty status (SMD = -1.40, 95 % CI:-2.05 to -0.75, P < .05) and had a significant impact on physical function (muscle strength: SMD = 0.31, 95 % CI: 0.01-0.61, P < .05; gait speed: SMD = 0.27, 95 % CI: 0.02-0.52, P < .001; balance: SMD = 0.27, 95 % CI: 0.05-0.49, P = .02; Short Physical Performance Battery [SPPB]: SMD = 1.03, 95 % CI: 0.65-1.42, P < .001; and Timed Up and Go [TUG]: SMD = -3.05, 95 % CI: -3.90 to -2.19, P < .001). Subgroup analysis suggested that a 12-week duration is optimal for multicomponent exercise interventions, demonstrating significantly greater effectiveness in hospital compared with out-of-hospital.
Conclusions:
Multicomponent exercise intervention can improve frailty status in older adults and promote enhancement of physical functional abilities (muscle strength, gait speed, balance, SPPB, and TUG). Therefore, a possible protective effect of multicomponent exercise in frailty older adults is suggested.

Endurance exercises
Endurance exercises involve running, swimming, or cycling, which require repetitive movements with low force output. When a person engages in endurance exercise, a few noticeable changes occur in their skeletal muscles. For instance, the number of capillaries...

The cellular clock theory posits that the human lifespan is closely tied to the finite capacity of cells to divide, a phenomenon governed by telomeres, which are protective caps at the ends of...
01:20Exercise and Cardiovascular Response
Light to moderate physical activity initiates a series of interconnected responses in the body. The heart rate modestly increases in anticipation of the workout, followed by widespread vasodilation as oxygen consumption by skeletal muscles increases. This results in decreased peripheral resistance, increased capillary blood flow, and accelerated...
01:29Bone Disorders
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...
