| English abstract | A key feature of physical activity is that it results in an increased rate of energy expenditure and, as a result of metabolic inefficiencies that lead to high heat production, an increase in the requirement to dissipate the added heat through sweat. Nevertheless, studies assessing food and fluid intakes of athletes commonly find that they fail to optimally satisfy their daily predicted requirements of both energy and fluid, causing them to perform at levels below their conditioned capacities. To some extent, this problem results from an excess reliance on the sensations of ‘hunger’ and ‘thirst’ to guide energy and fluid intakes. However, there are also common misunderstandings of the best nutrition strategies for achieving optimal body composition and performance. Athletes in all sports should strive to improve the strength-to-weight ratio to enable an enhanced ability to overcome sport-related resistance, but this may be misinterpreted as a need to achieve a lower weight, which may result in an under-consumption of energy through restrained eating and special ‘diets’. The outcome, however, is nearly always the precise opposite of the desired effect, with lower strength-to-weight ratios that result in an ever-increasing downward spiral in energy consumption. This paper focuses on within-day energy balance eating and drinking strategies that are now successfully followed by many elite-level athletes, including long-distance runners, sprinters, gymnasts, figure skaters, and football players. These strategies can help athletes avoid the common errors of under-consumption while simultaneously improving both body composition and performance |
