Background:

Physical activity and fitness in adolescence may improve cognition in adulthood by increasing insulin-like growth factor I (IGF-I).

Methods:

As part of the Amsterdam Growth and Health Longitudinal Study, following subjects from age 13 to 42 years, physical activity and fitness of 303 subjects were assessed annually between the ages 13 to 16. At mean age 36, physical activity, fitness and IGF-I were measured. At mean age 42, IGF-I and cognitive factors (ie, executive functioning and visual-spatial memory) were measured. The linear regression of physical activity and fitness in adolescence and IGF-I in adulthood on cognitive scores in adulthood was investigated.

Results:

A significant association was found in males between physical activity in adolescence and executive function in adulthood (Spatial Working Memory Between Errors: β = –.18, B = –.13, 95% CI = –.259 to –.010; Spatial Working Memory Strategy: β = –.20, B = –.08, 95% CI = –.147 to –.014). No association between physical activity or fitness in adolescence and cognitive function in adulthood was found in females, nor any intermediate role for IGF-I in either sex.

Conclusions:

The results suggest a stimulating effect of adolescent physical activity in males on executive functions in adulthood, emphasizing the importance of an active lifestyle among adolescent males.

Cognitive decline is a common feature of aging. Physical activity is a modifiable lifestyle factor that has been identified as positively impacting cognitive health of older adults. Here, we review the current evidence from epidemiological (i.e., longitudinal cohort) and intervention studies on the role of physical activity and exercise in promoting cognitive health in older adults both with and without cognitive impairment. We highlight some of the potential underlying mechanisms and discuss some of the potential modifying factors, including exercise type and target population, by reviewing recent converging behavioral, neuroimaging, and biomarker evidence linking physical activity with cognitive health. We conclude with limitations and future directions for this rapidly expanding line of research.

Regular physical activity and exercise (PA&E) reduces cognitive aging, may delay dementia onset, and for persons with dementia, may slow progression and improve quality of life. Memory clinic patients and caregivers described their PA&E and completed the Older Persons’ Attitudes Toward Physical Activity and Exercise Questionnaire (OPAPAEQ). Caregivers and patients differed in their PA&E attitudes: patients were less likely to believe in the importance of PA&E for health promotion. PA&E attitudes were explored as predictors of self-reported exercise habits. Belief in the importance of high intensity exercise for health maintenance was the only variable that significantly predicted engagement in regular PA&E. Moreover, caregivers’ attitudes toward high intensity exercise predicted memory patients’ participation in PA&E. These findings may aid in development of exercise interventions for people with memory problems, and suggest that modification of specific attitudes toward exercise is an important component to ensure maximum participation and engagement in PA&E.

exponentially with age, particularly above the age of 75 years ( World Health Organization, 2015 ), cognitive aging may start as early as in the third and fourth decades of life, due to structural and functional brain changes ( Harada, Love, & Triebel, 2013 ; Salthouse, 2009 ). These changes primarily affect
