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.

Participants: 80
Duration: 8 weeks
Intervention: 8-week multicomponent group exercise program
Outcome: Physical performance (gait speed, arm curls, grip strength, heart rate recovery) and sleep quality
Effect Size: N/A
Population: Community-dwelling older adults in Taiwan (n=80, from community care sites)

Result: 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.

Limitations

  • ⚠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.
