<p> </p><p>Abstract
</p><p>This research investigates the impact of physical activity on cognitive function in older adults, with implications for promoting cognitive health and well-being in aging populations. A comprehensive review of existing literature highlights the potential protective effects of physical activity against cognitive decline and neurodegenerative diseases in older adults. The study employs a mixed-methods approach, combining quantitative assessment of physical activity levels and cognitive function with qualitative exploration of potential mechanisms and moderators of the relationship between physical activity and cognitive health. Preliminary findings suggest that regular physical activity is associated with improved cognitive function across various domains, including memory, executive function, and processing speed, in older adults. Key factors influencing the relationship between physical activity and cognitive function include the type, intensity, and duration of physical activity, as well as individual characteristics such as age, sex, and comorbidities. The study provides insights into the potential mechanisms underlying the protective effects of physical activity on cognitive health and identifies areas for future research, such as personalized interventions and longitudinal studies. Implications for promoting healthy aging and enhancing cognitive well-being in older adults are discussed, emphasizing the importance of integrating physical activity into comprehensive preventive strategies for age-related cognitive decline.</p> <br><p></p>

Thesis Overview

<p> </p><p><strong>Chapter 1: Introduction</strong></p><p><strong>1.1 Background</strong></p><p>As the global population ages, maintaining cognitive function in older adults has become a significant public health concern. Cognitive decline is associated with various age-related neurodegenerative diseases such as Alzheimer's disease and vascular dementia. Engaging in regular physical activity has emerged as a potential protective factor against cognitive decline and may promote cognitive health in older adults. Understanding the relationship between physical activity and cognitive function is crucial for developing effective interventions to support healthy aging.</p><p><strong>1.2 Rationale</strong></p><p>Despite growing evidence suggesting a positive association between physical activity and cognitive function in older adults, there remains a need for further exploration into this relationship. Clarifying the mechanisms underlying the impact of physical activity on cognitive function and identifying optimal types, intensities, and durations of physical activity for cognitive health can inform preventive strategies and interventions aimed at promoting cognitive well-being in aging populations.</p><p><strong>1.3 Objectives</strong></p><p>The primary objective of this research is to explore the impact of physical activity on cognitive function in older adults. Specifically, the study aims to:</p><ol><li>Review existing literature on the relationship between physical activity and cognitive function in older adults, including potential mechanisms and moderators of this relationship.</li><li>Investigate the effects of different types, intensities, and durations of physical activity on various domains of cognitive function, such as memory, executive function, and processing speed, in older adults.</li><li>Examine potential moderators, such as age, sex, genetic factors, and comorbidities, that may influence the relationship between physical activity and cognitive function in older adults.</li><li>Discuss the implications of findings for promoting cognitive health and well-being in aging populations and identify areas for future research.</li></ol><p><strong>1.4 Structure of the Thesis</strong></p><p>This thesis is organized into five chapters. Chapter 1 provides an introduction to the research topic, including background information, rationale, objectives, and the structure of the thesis. Chapter 2 presents a comprehensive review of relevant literature on physical activity, cognitive function, and aging, highlighting current evidence and gaps in knowledge. Chapter 3 describes the methodology employed in this research, including study design, participant recruitment, physical activity assessment, cognitive function measures, and data analysis procedures. Chapter 4 presents the findings of the study, including the impact of physical activity on cognitive function in older adults and potential moderators of this relationship. Finally, Chapter 5 discusses the implications of the findings for promoting cognitive health in aging populations, limitations of the study, and provides recommendations for future research and practice.</p> <br><p></p>
