tailieunhanh - Exercise Physiology: For Health, Fitness, and Performance_2

Exercise Physiology for Health, Fitness, and Performance, Second Edition, reprinted by LWW, integrates basic exercise physiology with research studies to stimulate learning, allowing readers to apply principles in the widest variety of exercise and sport science careers. It combines basic exercise physiology with special applications and contains flexible organization of independent units, so instructors can teach according to their own approach. Each unit is designed with a consistent and comprehensive sequence of presentation: basic anatomy and physiology, the measurement and meaning of variables important to understanding exercise physiology, exercise responses, training principles, and special applications, problems, and considerations | ỉ I fl 13 Cardiorespiratory Training Principles and Adaptations After studying the chapter you should be able to Describe the exercise physical activity recommendations of the American College of Sports Medicine the Surgeon General s Report the ACSM AHA Physical Activity and Public Health Guidelines the National Association for Sport and Physical Education and the CDC Expert Panel. Discuss why these reports contain different recommendations. Discuss the application of each of the training principles in a cardiorespiratory training program. Explain how the FIT principle is related to the overload principle. Differentiate among the methods used to classify exercise intensity. Calculate training intensity ranges by using different methods including the percentage of maximal heart rate the percentage of heart rate reserve and the percentage of oxygen consumption reserve. Discuss the merits of specificity of modality and cross-training in bringing about cardiovascular adaptations. Identify central and peripheral cardiovascular adaptations that occur at rest during submaximal exercise and at maximal exercise following an aerobic endurance or dynamic resistance training program. 388 CHAPTER 13 Cardiorespiratory Training Principles and Adaptations 389 INTRODUCTION In the last decade physical fitness-centered exercise prescriptions which emphasize continuous bouts of relatively vigorous exercise have evolved for the nonathlete into public health recommendations for daily moderateintensity physical activity. Early scientific investigations that led to the development of training principles for the cardiovascular system almost always focused on the improvement of physical fitness operationally defined as an improvement of maximal oxygen consumption VO2max . Such studies formed the basis for the guidelines developed by the American College of Sports Medicine 1978 as the recommended quantity and quality of exercise for developing and maintaining fitness in healthy adults. .
