Predictors of adherence to a structured exercise program for older women

Area of Science:

• Gerontology
• Exercise Science
• Behavioral Medicine

Background:

• Structured exercise programs are crucial for older adults' health.
• Understanding adherence factors is key to program success.
• Limited research exists on predictors of adherence in older women.

Purpose of the Study:

• To identify psychological, physiological, and health/lifestyle factors associated with adherence to a structured exercise program in older women.
• To differentiate predictors of adherence during a trial versus long-term participation.

Main Methods:

• Longitudinal study with 102 women aged 60-85.
• Assessment of psychological, physiological, and lifestyle measures before and after a 12-month exercise trial.
• Multiple regression analysis to determine predictors of adherence.

Main Results:

• Reduced muscle strength, slow reaction time, and psychoactive drug use predicted adherence during the trial.
• Muscle strength, reasoning ability, depression, and self-reported strength improvement predicted continued participation post-trial.

Conclusions:

• Adherence predictors differ between short-term trial participation and long-term engagement.
• Targeting specific factors like muscle strength and cognitive function may enhance exercise program adherence in older women.
