Summary

Center-based exercise improved physical function in older adults for up to a year. However, these benefits diminished when participants transitioned to home-based routines, suggesting ongoing classes may be needed for sustained improvements in physical performance.

Area of Science:

  • Gerontology and Exercise Science
  • Geriatric Rehabilitation
  • Physical Therapy Interventions

Background:

  • Older adults are at risk for declining physical functioning, impacting independence.
  • Community-dwelling seniors with mobility impairments require effective interventions.
  • Understanding the long-term effects of different exercise settings is crucial.

Purpose of the Study:

  • To evaluate the impact of center-based exercise on physical performance in older adults.
  • To compare center-based exercise with home-based exercise in seniors at risk for functional decline.
  • To determine the sustainability of exercise benefits after transitioning to home-based programs.

Main Methods:

  • Randomized controlled trial involving 155 community-dwelling older adults (≥70 years) with mobility impairments.

  • Intervention group: supervised center-based exercise (endurance, strength, balance, flexibility) for 12 months, followed by home exercise.
  • Control group: home-based endurance exercise instruction.
  • Outcome measures: MacArthur battery, Physical Performance Test (PPT-8), 6-Minute Walk Test (6MWT) assessed over 18 months.

    • Main Results:

    • The center-based exercise group showed significant improvements in the MacArthur battery scores at 3, 6, and 12 months compared to the home control group.
    • Improvements in the MacArthur battery were not sustained at 18 months after the intervention shifted to home-based exercise.
    • No significant improvements were observed in the PPT-8 or 6MWT for either group.
    • Predictors of sustained improvement included younger age, better baseline physical function, and self-perceived health.

    Conclusions:

    • Center-based exercise effectively enhanced gait, chair rise, and balance in older adults for the first year.
    • The benefits of center-based exercise were not maintained when participants transitioned to home exercise programs.
    • Ongoing supervised classes at senior centers may be essential for sustaining physical performance gains in older populations.
