[Truncated abstract] This thesis concerns itself primarily with the impact of exercise training on cardiac and vascular adaptations in humans. It contains longitudinal studies of individuals at either end of the physical activity spectrum; young elite athletes and obese children and adolescents. The study of these diverse groups was intentional, as a particular interest was to investigate the possible inter-relationships between morphological adaptations in the heart, evident in both obese and athletic populations, and the possible consequences of such adaptations for cardiac function. Whilst there exists a long tradition of echocardiographic assessment of cardiac dimensions and mass in both athletic and clinical populations, investigation of the impact of each of these “conditions” on cardiac diastolic function is novel, and has been facilitated by recent advances in the technical approach to diastolic function assessment in humans. Studies presented in the following chapters utilise advanced echocardiography imaging combined with pulse wave and tissue Doppler approaches to investigate the effects of exercise training regimen on wall thickness and ventricular mass, as well as diastolic function indices. State-of-the-art vascular imaging approaches have also been used in these populations to determine whether changes in vascular wall thickness, diameter or function occur with training in the elite athletes or obese youth.
