PY - 2011 T2 - Cardiovascular and Pulmonary Physical Therapy: An Evidence-Based Approach, 2e AB - It is one of the great marvels and mysteries of life that simple elements like carbon, hydrogen, and oxygen can be combined with a life force to produce human existence and movement. These elements are found in carbohydrate, fat, and protein—the food substrates that we consume. This chapter begins with quantification of energy expenditure and then describes the formation of energy substrates and their subsequent breakdown. Nutrition for optimum health will be explored. Adenosine triphosphate (ATP) will be appreciated as the link between the breakdown of food and the ability to perform physical activity. Exercise states will be described as a function of metabolic pathways. Obesity and measurement of body composition will be discussed. The chapter concludes with components of a physical fitness program and principles of exercise prescription.
