In this study, the writers report the aspect of the dietary management of seven professional bicycle-racers who participated in the Grand Tour and the World Cup Race as the members of the Italian team. 1) The Figure 1-1 and 1-2 shows the monitored heart rate of Mr. Daisuke Imanaka, a member of this study, when he raced in Tour de France in 1996. The strength of physical exercise was measured at over V02max60% and was sustained for 70 to 80 percent of the time during the race, and the high rate of the energy consumption in glucide was seen. 2) The average height and weight of the seven professional bicycle-racers, who were studied in this paper, were 173.3 cm and 62.3 kg, and the body-fat ratio was 7.1% with BMI 20.8. This shows they had muscled bodies with reduced body-fat. 3) The dietetic intake for daily training, shown in the Chart 3, indicates that the energetic intakes on the days of race-training were 6,868±526kcal, and the coefficient of variation was 7.7. The energetic intakes of the seven bicycle-racers were very close to that of the average to get ready for the race. The intake of protein was 4 grams per kilogram in one's weight and constituted 14% of the total energy consumption daily. The changes of the dietetic intake during the training period were studied and the writers find that the result is satisfactory. 4) On the PFC ratio, the energy ratio of glucide was 70 to 80% when the breakfast of the race-training and the meals of regular training period were studied, and the energetic supply was sufficient for the races. The energy ratio of protein was increased by 20 to 25% for the dinner and the meals after the training to recover the racers' physical strength by next mornings supplying the balanced meals. As a result of this study, the writers find that the seven professional bicycle racers of the Italian team had been taking the programmed nutrients for their training and races. The ratio of the nutrients to supply energy in each meal was well adjusted considering their training and races to increase their strength and also to maintain their healthy conditions. Thus the writers conclude that setting a target intake of nutrients for such athletic races and training should be necessary considering the hardness of exercises and the purposes.
