Summary
Cognitive decline in aging is linked to physical and functional factors. Women, younger age, more education, and higher general functional fitness predict better cognitive performance in older adults.
Area of Science:
- Gerontology
- Cognitive Neuroscience
- Physical Therapy
Background:
- Aging is associated with a decline in physiological and cognitive functions.
- Understanding predictors of cognitive performance in the elderly is crucial for interventions.
Purpose of the Study:
- To identify physical and functional predictors of cognitive performance in Brazilian elderly.
- To analyze the relationship between executive functions and functional fitness.
Main Methods:
- A sample of 498 Brazilian elderly individuals participated.
- Executive functions were assessed using the Stroop test.
- Functional fitness was evaluated using the General Functional Fitness Index (GFFI).
Main Results:
- Female sex, younger age, higher education, and greater GFFI scores predicted better cognitive performance.
- Muscle strength in upper and lower limbs significantly influenced test execution time.
- Body mass index and nutritional status were not significant predictors.
Conclusions:
- Gender, age, education, and functional fitness are key predictors of cognitive performance in older adults.
- Interventions targeting functional fitness may support cognitive health in the elderly.
