Summary

Older adults with limited functional ability can improve their physical function through various exercises. Resistance training showed the most consistent gains in functional tasks over 16 weeks.

Area of Science:

  • Gerontology
  • Exercise Physiology
  • Rehabilitation Science

Background:

  • Functional ability declines with age, impacting independence in older adults.
  • Limited functional ability in older adults (65+) is a significant public health concern.
  • Exercise interventions are crucial for maintaining and improving physical function in the elderly.

Purpose of the Study:

  • To compare the efficacy of resistance training, aerobic walking, and combined training on functional task performance in older adults with limited functional ability.
  • To determine which exercise modality yields the greatest improvements in functional measures over 16 weeks.
  • To assess the impact of different exercise programs on the functional capacity of elderly individuals.

Main Methods:

  • 131 older adults (≥65 years) with limited functional ability were randomized into four groups: resistance training, aerobic walking, combined training, or a non-exercise control.

  • Participants engaged in three weekly exercise sessions for 16 weeks, with exercise groups achieving 70% compliance.
  • Functional ability was assessed using six measures at baseline, 8 weeks, and 16 weeks.

    • Main Results:

    • All three exercise intervention groups (resistance, aerobic, combined) showed significant improvements in functional ability measures.
    • The resistance training group demonstrated the most consistent gains across all six functional measures compared to other groups.
    • Aerobic walking and combined training also led to significant functional improvements, though less consistently than resistance training.

    Conclusions:

    • Older adults with limited functional ability can enhance their physical function through various exercise programs.
    • Resistance training appears to be a highly effective modality for improving functional task performance in this population.
    • These findings support the integration of exercise, particularly resistance training, into strategies for maintaining older adults' independence and quality of life.
