An Italian proffesional bicycle road-racing team, Polti had a 10-day intensive training sessions from January 17th to 26th in 1995 at Sardinia in Italy, and one Japanese team-member joined the training sessions. In this paper, the writer studys the diet of the Japanese road-racer and calculates the intake of nutrients, energy consumption and PFC ratio from the time study. The writer also refers to the diet for weight reduction. The following is the result of this study: 1. The average intake of nutrients during the training sessions was 30 to 40% of the recommended amount for iron and vitamin B1 & B2, and 70 to 80% for other nutrients. The supplementary pills were used for supplying vitamins and minerals. 2. The energy supply and consumption were about 5,000 kcals each. 3. However, the energy consumption of the hard training day was 7,000 kcals while the energy supply was 4,700 kcals. On the cotrary, the energy supply exceeded the consumption on other days. 4. The ratio of saccharine energy was nearly 80% for the breakfast and snacks, and the ratio of protein was over 30% after the training for recovering when the PFC ratios were compared. 5. To reduce the adipose ratio of the body from 8% to 6% for losing weight, the adipose energy ratio was reduced to 21%. From the result of the study, the writer emphasizes the importance of "proper timing for properly balanced food" considering the aspect of training and its routine.
