Book Description
There is overwhelming evidence linking increased physical activity with positive changes in cognitive functioning and brain health. Much of what we know about these interrelationships comes from aerobic exercise training studies with older adults and children. This literature has paved the way for the neuroscientific investigation of mechanisms responsible for exercise-induced cognitive and brain health enhancement, a list that ranges from molecular changes to systemic changes in executive control and neural connectivity. A new perspective has also emerged that aims to understand executive control processes that may underlie the regulation of health behavior. In accordance with this view, physical activity falls under the umbrella of health behaviors that require a substantial amount of executive control. Executive control is a limited resource, and the aging process depletes this resource. People who regularly exercise are said to have higher “self-regulatory control”—planning, goal-shielding and impulse control—than irregular exercisers. The successful maintenance of physical activity participation in lieu of daily cognitive stressors likely reflects an adaptive resistance to control failures. Indeed, a handful of studies have shown the relationship between greater executive control and subsequently higher levels of physical activity. However, little is known about the neural correlates of physical activity adherence or sedentary behavior, with the view that neurocognitive factors have an antecedent and reciprocal influence on these behaviors. No research has focused on the brain networks responsible for the self-regulation of physical activity, which likely overlaps with structures and functions playing critical roles in the regulation of other health behaviors. Interdisciplinary investigations are needed to explain the extent to which physical activity self-regulation and self-regulatory failure is dependent upon, or under the influence of executive control processes and brain networks. Understanding the degree to which self-regulatory resources may be enhanced, restored, and trained will have enormous implications for basic science and applied fields. It is also of great import to understand whether or not physical activity self-regulation is a domain-specific behavior associated with specific brain networks, or to determine the extent to which regulatory network-sharing occurs. The aim of this Frontiers Research Topic is to curate contributions from researchers in social and cognitive neurosciences and related fields, whose work involves the study of physical activity behavior, self-regulation and executive control. For this Research Topic, we, therefore, solicit reviews, original research articles, and opinion papers, which draw theoretical or empirical connections related to sustained physical activity behavior, self-regulatory strategies, cognitive performance, and brain structure and function. While focusing on work in the neurosciences, this Research Topic also welcomes contributions in the form of behavioral studies, psychophysiological investigations, and methodological innovations. This Frontiers Research Topic will carve out new directions for the fields of exercise, cognitive, and social neurosciences. We hope you will consider submitting your work.

Book Description
Physical fitness affects our ability to function and be active. At poor levels, it is associated with such health outcomes as diabetes and cardiovascular disease. Physical fitness testing in American youth was established on a large scale in the 1950s with an early focus on performance-related fitness that gradually gave way to an emphasis on health-related fitness. Using appropriately selected measures to collected fitness data in youth will advance our understanding of how fitness among youth translates into better health. In Fitness Measures and Health Outcomes in Youth, the IOM assesses the relationship between youth fitness test items and health outcomes, recommends the best fitness test items, provides guidance for interpreting fitness scores, and provides an agenda for needed research. The report concludes that selected cardiorespiratory endurance, musculoskeletal fitness, and body composition measures should be in fitness surveys and in schools. Collecting fitness data nationally and in schools helps with setting and achieving fitness goals and priorities for public health at an individual and national level.

Book Description
Cardiorespiratory fitness reflects the ability of the cardiovascular and respiratory systems to transport oxygen to the working muscles of the human body during exercise. It is influenced by factors such as age, genetic structure, body composition, and gender. This book provides the reader with interesting and current data about cardiorespiratory fitness. Chapters cover such topics as pulmonary rehabilitation in chronic obstructive pulmonary disease, ischemic preconditioning, metabolic syndrome in adults, cardiorespiratory fitness and intellectual disability, influence of lifestyle on body composition, and effect of exercise on cognitive performance in the elderly.

Book Description
A growing body of literature suggests that higher levels of physical activity and cardiorespiratory fitness, as well as an alternative treatment such as low level laser therapy (LLLT), have beneficial effects on cognition, while sedentary lifestyle-induced obesity and vascular risk negatively influence cognition. However, the relationship between cardiorespiratory fitness and vascular risk on cognitive function and the effect of an acute bout of very vigorous aerobic exercise (acute exercise) on cognitive performance has not yet been investigated. Additionally, the effects of combined acute exercise and LLLT treatments on cognitive performance have not yet been characterized. Therefore, the goal of this dissertation was to conduct a series of three research studies ranging from a cross-sectional exploratory study about the association of cardiorespiratory fitness, obesity, and vascular risk on cognitive function, to an experimentally designed study that compared the effects of acute exercise, LLLT, and the combination of these two treatments on cognitive performance in young adults. Study1 examined the relationship among cardiorespiratory fitness (maximal oxygen consumption, VO2max), obesity indices (body mass index, BMI; waist circumstance), and vascular risk (C-reactive protein; CRP). Cognitive function included crystalized intelligence (Kaufman Brief Intelligence Test; KBIT), executive functions of inhibition (Stroop test), switching (Trail making test; TMT), attention (Psychomotor Vigilance Task; PVT), and working memory (Delayed-Match-to-Sample, DMS). Study 2 determined the effect of acute exercise on cognitive performance including executive response inhibition (Stroop test) and response switching (TMT) and brain-derived neurotrophic factor (BNDF). Study 3 compared the effectiveness of LLLT and acute exercise on cognitive performance, which included attention (PVT) and working memory (DMS). Results demonstrated there was a beneficial effect of physical exercise-induced improvements in cardiorespiratory fitness on vascular risk and cognitive functions particularly in working memory and inhibitory control (Study1). Acute exercise improved performance in inhibitory control and increased the BNDF level compared to the control condition, suggesting the acute exercise-induced the increase in BDNF level may be at least in part of mediating the cognitive performance improvement (Study 2). All three conditions (acute exercise, LLLT, or the combination) improved performance in attention and working memory, as measured by reaction time and response accuracy, when compared to a control group. Specially, the combined group showed a trend of greater improvement in attention and worming memory performance (Study 3). Taken together, the results of this research series suggest that acute exercise and LLLT can improve cognitive performance, which is also mediated by health indices including cardiorespiratory fitness, obesity, and vascular risk. It is anticipated that these findings will make substantive contributions to the empirical literature concerning the beneficial effect of exercise and LLLT on cognitive health in young adults, given the current paucity of research.

Book Description
Many studies have reported that regular physical activity and cardiorespiratory fitness were associated with cognitive performance and more selectively with executive functions. Among numerous physiological mechanisms that may underlie the association between them, prefrontal cortex oxygenation seems to play a major role. However, the specific impact of prefrontal oxygenation on the link between physical activity and cognition is influenced by several factors, such as gender, age, or cardiovascular health. Therefore, the aim of this thesis was to investigate the impact of physical activity and cardiorespiratory fitness on executive functions across the adults' age span in healthy males, as well as the influence of prefrontal cortex oxygenation and cardiovascular health. To obtain those objectives, we conducted a review of the effect of physical activity on the brain in older adults and four cross-sectional studies. From our review, we highlighted that: • In older adults, higher fitness level is associated with better performance in several executive function tests. Even though the limited number of studies available makes it difficult to draw definitive conclusions.• Better cardiovascular fitness in older adults is associated with improve arterial stiffness, higher vascular reactivity, and greater amplitude of cerebral oxygenation during exercise or cognitive tasks.• Greater gray matter volume and white matter integrity were related to the cardiorespiratory fitness but less consistently related to physical activity.• At least 12 weeks of an aerobic exercise program are required to give advantageous effects to the brainAnd our experimental works show that:In young males:• The active individuals performed better in executive tasks than their inactive counterparts and had a larger change in prefrontal cortex oxygenation during the most complex conditions of Stroop task.• High cardiorespiratory fitness was related to a better performance in dual-task and greater oxygenation on both sides of the prefrontal cortex.In older males:• Cardiorespiratory fitness is not related to Stroop task performance nor prefrontal cortex oxygenation in overall older males.• Higher cardiorespiratory fitness was related to a better performance and greater right prefrontal cortex oxygenation during a Stroop task in 61+ years old group but not in 55-60 years old group, suggesting the importance of age-group classification to evaluate the effect of cardiorespiratory fitness on executive function in older male subjects.• Older males have stronger relationships between several vascular parameters and Stroop task performance than young malesThis work shows the relationship between physical activity and cardiorespiratory fitness on executive functions in young and older males. The potential neurophysiological mechanisms that underlie that relationship, especially prefrontal oxygenation and vascular health, are presented.

Book Description
Exercise-Cognition Interaction: Neuroscience Perspectives is the only book on the market that examines the neuroscientific correlation between exercise and cognitive functioning. The upsurge in research in recent years has confirmed that cognitive-psychology theory cannot account for the effects of exercise on cognition, and both acute and chronic exercise effect neurochemical and psychophysiological changes in the brain that, in turn, affect cognitive functioning. This book provides an overview of the research into these effects, from theoretical research through current studies that emphasize neuroscientific theories and rationales. It addition, users will find a thorough examination of the effects of exercise interventions on cognitive functioning in special populations, including the elderly, children, and those suffering from a variety of diseases, including schizophrenia, diabetes, and an array of neurological disorders. With contributions from leading researchers in the field, this book will be the go-to resource for neuroscientists, psychologists, medical professionals, and other researchers who need an understanding of the role exercise plays in cognitive functioning. - Provides a comprehensive account of how exercise affects brain functioning, which in turn affects cognition - Covers both theory and empirical research - Presents a thorough examination of the effects of exercise interventions on cognitive functioning in special populations, including the elderly, children, and those suffering from a variety of diseases - Examines neurochemical, psychophysiological, and genetic factors - Covers acute and chronic exercise
