Diet and nutrition significantly affect sport and exercise performance. The food and fluid which an athlete before, during, and after training and competition affects health and body composition, as well as performance in, and, recovery from, the effects of exercise. An optimum diet can help to maximize athletic performance. Increased participation in physical activity, exercise and sport has the potential to improve the health and well-being of our sedentary population. Increased physical activity can help to reduce obesity, the risk of heart disease, diabetes, some cancers, osteoporosis, and can play a role in promoting positive mental health and psychological wellbeing. Sound knowledge of sport and exercise nutrition can ensure a healthy balance between exercise and diet of individuals and groups of individuals at all levels of fitness. Due consideration must be given to the special nutritional needs imposed by participation in different forms of sport or exercise in combination with the circumstances and characteristics of the individual. Whilst evidence clearly shows that good diet and nutrition are vital for health in all individuals, a growing variety of ‘health’ foods, ergogenic aids, supplements, herbal remedies and functional foods are widely available. These products claim to benefit health and athletic performance but such claims are often unsubstantiated. In addition many nutritional practices in sport (e.g. making weight) are based more on tradition and myth than scientific evidence. There is therefore a growing need for appropriate guidance in relation to sport and exercise nutrition, across a wide-spectrum from amateur to elite professional levels within sports. This programme provides a postgraduate pathway for graduates who wish to pursue a career within the area of sports nutrition.
