An 8-week multicomponent group exercise program improves muscle strength and sleep quality in community-dwelling older adults in Taiwan.
This quasi-experimental study found that an 8-week multicomponent group exercise program significantly improved gait speed, upper limb muscle strength, sleep quality, and heart rate recovery in the intervention group compared to baseline. Between-group posttest comparisons showed significant differences in arm curls, grip strength, and sleep quality favoring the intervention group.

An 8-week multicomponent group exercise program improves muscle strength and sleep quality in community-dwelling older adults in Taiwan. The current body of evidence comprises 1 study. EvidenceHub rates the overall confidence at 32/100 (low).
The Claim
An 8-week multicomponent group exercise program improves muscle strength and sleep quality in community-dwelling older adults in Taiwan.
This conclusion is most relevant to: Community-dwelling older adults in Taiwan (n=80, from community care sites).
What the Research Shows
The conclusion draws on 1 linked study. Highlights from the cited literature:
- ▸The Effects of a Multicomponent Group Exercise Program on Physical Performance and Sleep Quality in Older Adults in Taiwan. (Asia-Pacific journal of public health, 2026) — This quasi-experimental study found that an 8-week multicomponent group exercise program significantly improved gait speed, upper limb muscle strength, sleep quality, and heart rate recovery in the intervention group compared to baseline. Between-group posttest comparisons showed significant differences in arm curls, grip strength, and sleep quality favoring the intervention group.
How It Works
The proposed biological pathway:
- ▸Exercise improves cardiovascular fitness and muscle strength
- ▸Enhanced physical activity promotes better sleep regulation
- ▸Group setting may improve social engagement and adherence
- ▸Result: Improved muscle strength and sleep quality
Who Might Benefit
Evidence fit by population:
- ▸Community-dwelling older adults in Taiwan (n=80, from community care sites)
Recommended Dose
8 weeks, frequency and duration of sessions not specified in abstract
Limitations & Caveats
Important context when interpreting this evidence:
- ▸Quasi-experimental design without randomization limits causal inference
- ▸Abstract does not report blinding, dropout rates, or specific effect sizes
- ▸Single geographic location (central Taiwan) limits generalizability
Frequently Asked Questions
What type of exercise was included in the multicomponent program?▼
The abstract does not specify the exact components, but multicomponent programs typically include aerobic, strength, balance, and flexibility exercises.
How was sleep quality measured in this study?▼
The abstract does not specify the sleep quality assessment tool, but it likely used a validated questionnaire such as the Pittsburgh Sleep Quality Index (PSQI).
Was the study a randomized controlled trial?▼
No, it used a quasi-experimental control-group design, meaning participants were not randomly assigned to groups.
How many participants completed the study?▼
The abstract states 80 participants were involved, but does not report completion rates or attrition.
