TY - CHAP M1 - Book, Section TI - Energy Requirements and Measurement of Energy Expenditure A1 - Manore, Melinda M A2 - Burke, Louise A2 - Deakin, Vicki A2 - Minehan, Michelle Y1 - 2021 N1 - T2 - Clinical Sports Nutrition, 6e AB - Most individuals, including athletes, maintain a stable body mass (BM) over long periods of time, while paying little attention to the amount of energy consumed or expended each day. However, energy balance is of primary concern to athletes who want to alter BM and/or composition to improve their exercise performance or meet a designated weight requirement for their sport. When energy consumption is insufficient to match that expended, much of the effort of training can be lost, since both muscle and fat will be used for energy. In addition, if energy intake is limited or restricted, the ability to obtain other essential nutrients, such as carbohydrate (CHO), protein, fat, vitamins and minerals—which are necessary for optimal sport performance and good health—will also be compromised.
