Tai Chi significantly improved both self-efficacy and physical function in older adults. These enhancements were positively associated, suggesting improved movement confidence leads to greater perceived physical capability.

Area of Science:

  • Gerontology
  • Exercise Science
  • Behavioral Medicine

Background:

  • Physical inactivity in older adults is linked to decreased physical function and quality of life.
  • Self-efficacy, or belief in one's ability to perform tasks, may play a crucial role in maintaining physical function.
  • Understanding exercise interventions that can enhance self-efficacy and physical function is vital for healthy aging.

Purpose of the Study:

  • To investigate the impact of a Tai Chi intervention on self-efficacy and physical function in older adults.
  • To examine the association between changes in self-efficacy and physical function over the course of the intervention.
  • To explore the potential of Tai Chi as a method to improve health-related quality of life in the elderly population.

Main Methods:

  • Ninety-four healthy, inactive older adults were randomized into a 6-month Tai Chi group or a wait-list control group.
  • Self-reported movement efficacy and physical function were assessed at baseline, mid-point, and end of the study.
  • Multisample latent curve analyses were employed to analyze changes in outcome variables and their associations.

    • Main Results:

    • The Tai Chi intervention group demonstrated significant improvements in both self-efficacy and physical function compared to the control group.
    • A positive association was found between self-efficacy and physical function, indicating that increased movement confidence correlated with enhanced perceived physical capability.
    • Participants in the Tai Chi group showed significant progress in their perceived ability to perform movements and their overall physical functioning.

    Conclusions:

    • Tai Chi is an effective exercise modality for enhancing self-efficacy and physical function in older adults.
    • Improvements in self-efficacy are directly related to gains in perceived physical capability among older adults engaging in Tai Chi.
    • Further research is warranted to explore the relationship between exercise self-efficacy and physical function for optimizing health-related quality of life in aging populations.
