Recently, in addition to a diet which should reflect the day-to day needs of training sessions, a proper environment for training and recovery as well as proper timing of meals are recognized as essential for improvement of athletic performance. Hence in order to improve their athletic performance, an increasing number of elite athletes are adopting a lifestyle which emphasizes a proper enviroment for training and recovery. This report describes the successful lifestyle adopted by a female marathon runner who won a gold medal at the IAAF World Championships in Athens in August 1997. During the period of intensive training, meals were provided promptly after the end of each training session to facilitate replenishment of nutrients, and an extended rest period enhanced recovery from the intense training. In the diet, careful consideration was given to total energy, the fraction of energy derived from each of the three main energy sources(fat, carbohydrate, and protein), and proper intake of vitamins and minerales. In addition, each meal was prepared in order to provide an appropriate nutritional content to aid post-training recovery as well as to prepare for future training sessions. In other words, instead of average nutritional(including energy)requirements, day-to-day requirements were used to determine the menu for each meal. In this case study, it was found that an athletic lifestyle characterized by a proper environment for training and recovery as well as a proper diet which reflects the training menu, was conductive to improvement of athletic performance.
