Sport and exercise performance are influenced by diet and nutrition. Athletes' health and body composition, as well as performance and recovery, are influenced by the food and drink they take before, during, and after exercise. A thorough understanding of sport and exercise nutrition may help athletes of all levels, from amateur to elite, achieve a good balance of exercise and diet. The sciences of Sports Exercise Science and Human Nutrition study how individuals interact with food, sport, and exercise. Mechanical, physiological, and psychological responses to human movement, as well as how these responses affect exercise performance capacity and health effects, are all covered in sport and exercise science. So, Sport and Exercise Nutrition investigates how sport, exercise, and food influence human health and performance, as well as how nutrition influences sports health and performance. Obesity, diabetes, heart disease, and cancer are among disorders that can be influenced by exercise, sport, and eating. Sport and exercise nutrition is a fast-growing field that necessitates a thorough understanding of both human nutrition and physical activity's involvement in health.
