He earned his BSc degree in Biology with minor in Chemistry from KSU, and PhD degrees in clinical Exercise Physiology from USA in 1985. His research involves the investigation of physical activity/inactivity, sedentary behaviors, energy expenditure and obesity relative to cardiorespiratory fitness and cardio-metabolic health. He also studies the interaction between lifestyle habits, obesity and health, especially in children and youth. He has been the principle investigator in numerous funded research projects in physical activity, energy expenditure, obesity and cardio-metabolic health and fitness in Saudi children and youth. Professor Al-Hazzaa has published ten books, edited 3 more books and contributed numerous chapters in published books. In addition, he has published nearly 200 scientific papers in local, regional and international peer reviewed journals in the areas of exercise physiology/sports medicine, adolescent’s lifestyle behaviors, childhood obesity and physical activity, fitness, fatness & cardio-metabolic health. He is a Fellows of the American College of Sports Medicine and the European College of Sport Science as well as a member of numerous scientific organizations in the field of sports medicine, sports science, clinical exercise physiology, public health, health promotion and pediatric exercise medicine. He serves in the editorial boards of numerous regional and international Journals in obesity, sports medicine and exercise medicine and Rehabilitation. He is a regular peer reviewer for 45 regional and international journals. Professor Al-Hazzaa has recently served as a lead guest editor in a special issue of Journal of Nutrition and Metabolism.
