Book Description
Appropriate for professionals in gerontology, sports psychology, health psychology, physical education and social science programs that deal with older populations and community resources, this book first discusses the pros and cons of physical activity for older persons. It then explores the theoretical reasons for which older people do not pursue physical activity and how to overcome this reluctance. There is a model included, as well as implications for future social policy.

This title seeks to expand on reader's understanding by examining whether and how physical activity could indirectly affect cognitive function by influencing mediators that provide physical and mental resources for cognition.

Book Description
Active Living Among Older Adults is a reference text for a broad spectrum of scientific studies on the health effects of active living among older adults, and offers professionals and students easy access to the evidence that supports physically active lifestyles among the elderly. O'Brien Cousins and Home demonstrate that active living is beneficial and available to the elderly community. The perceived effects of active living are organized into separate categories, including physical health, disease prevention, psychosocial attitudes, lifestyle behavior, and economic well-being.

Book Description
In the older adult population, there is a high rate of decline in cognitive functioning. It has been reported that improving fitness levels exhibits a positive effect on cognition (Colcombe & Kramer, 2003; Colcombe et al., 2004). Older adult females 60-75 years of age who were moderately to highly fit performed better on working memory tasks after an acute bout of moderate or high-intensity aerobic exercise than before exercise. Participants included healthy females (N = 11) who were not on medications for cognitive impairment and who did not show signs of dementia or Alzheimer's disease. A submaximal walking exercise test was administered to assess fitness levels, as well as modified flanker tasks and d2-tests, to measure executive functioning in the brain. Results indicated that older adults females, 60-75 years of age showed improved scores on the modified flanker task and d2-tests after a session of moderate or high-intensity aerobic exercise. These findings suggest that an acute bout of exercise, regardless of intensity, can improve tests of executive control.

Book Description
Background: Performing aerobic exercise and maintaining high levels of aerobic fitness may have positive effects on both brain structure and function in older adults. Despite decades of research however, there is still a rather poor understanding of the neurocognitive mechanisms explaining the positive effects of aerobic exercise on cognition. Changes in prefrontal gray matter as well as dopaminergic neurotransmission in striatum are both candidate neurocognitive mechanisms. The main aims of this thesis are: 1. To investigate the effects of aerobic exercise and fitness on cognition and magnetic resonance imaging (MRI) derived gray matter volumes using data from a 6 month physical exercise intervention in older adults (Study I). 2. To simulate the effect of atrophy in longitudinal positron emission tomography (PET) which could pose a challenge to interpreting changes in longitudinal PET imaging (Study II). 3. To study the influence of aerobic exercise and fitness on the dopamine D2-receptor (D2R) system in striatum using [11C]raclopride PET as a potential mechanism for improved cognition (Study III). Results: In Study I, aerobic exercise was found to improve cognitive performance in a broad, rather than domain-specific sense. Moreover, aerobic fitness was related to prefrontal cortical thickness, and improved aerobic fitness over 6 months was related to increased hippocampal volume. In Study II, we identified areas in the striatum vulnerable to the effect of shrinkage, which should be considered in longitudinal PET imaging. Finally, in Study III, the effect of being aerobically fit, and improving fitness levels was found to impact dopaminergic neurotransmission in the striatum, which in turn mediated fitness-induced improvements in working memory updating performance. Conclusion: The findings in this thesis provide novel evidence regarding the neurocognitive mechanisms of aerobic exercise-induced improvements in cognition, and impacts the interpretation of longitudinal PET imaging. Performing aerobic exercise and staying aerobically fit at an older age have positive effects on cognition and brain systems important for memory and cognition. Specifically, fitness-induced changes to the dopaminergic system stands out as one novel neurocognitive mechanism explaining the positive effects of aerobic fitness on working-memory performance in healthy older adults.
