Applying theory of planned behavior to predict exercise maintenance in sarcopenic elderly

Area of Science:

• Gerontology
• Behavioral Science
• Public Health

Background:

• Sarcopenia, a common condition in the elderly, is associated with reduced physical activity.
• Understanding the psychological factors influencing exercise behavior is crucial for developing effective interventions.

Purpose of the Study:

• To investigate the factors associated with exercise behavior among sarcopenic elderly people using the theory of planned behavior (TPB).
• To identify key predictors of exercise intention and actual behavior in this population.

Main Methods:

• A study involving 65 sarcopenic elderly individuals (34 in exercise group, 31 in control group).
• Application of structural equation modeling based on TPB components (attitude, subjective norm, perceived behavioral control).
• Assessment of exercise intention and behavior at baseline and after a 12-week intervention.

Main Results:

• Attitude and perceived behavioral control were key predictors of exercise intention in men at baseline.
• Subjective norm was the primary predictor for women at baseline.
• Both attitude and subjective norm predicted intention after 12 weeks, with gender-specific variations.
• "Feeling healthier with exercise" enhanced intention and maintenance for both genders.
• "Lack of motivation" was a significant barrier for men.

Conclusions:

• The theory of planned behavior (TPB) is a valuable framework for understanding and predicting exercise maintenance in the elderly with sarcopenia.
• Interventions should consider gender-specific psychological factors and emphasize the perceived health benefits of exercise.
