As these is a lack of visual information in visually impaired athletes, it is necessary to devise support methods, such as assessment, monitoring, and nutritional education, for adequate nutritional support. In this report, from 2015 to the 2016 Rio de Janeiro (Rio) Paralympic Games, nutritional support for weight gain was provided to a male swimmer with no light perception.We monitored the athlete’s body mass (BM) and energy intake, the former using a weighing scale with voice guidance and the latter by dietary surveys. The content and quantity of meals were reported by the athlete and team staff. Before the intervention, the BM and energy intake were 65 kg and 3700kcal, respectively. The target BM was set to 70kg and energy intake 4500 kcal, and the meal amount
was increased to support this. The athlete used eating out services for many meals. A dietician provided advice on menu selection while eating out and food selection at supermarkets and convenience stores. The team staff supported the athlete based on this advice. Additionally, a dairy product delivery service was used, and lunch boxes were made at the cafeteria the athlete used daily. For nutritional education, a dietitian went to the cafeteria, supermarket, or convenience store with the athlete, and nutritional information was provided on the spot. Hence, there was an energy intake increase of 4400-4900 kcal and weight gain. Occasionally, the target BM was reached, but it was not maintained during the Rio Paralympic Games. Through cooperation from the team staff, a dairy product retailer, and the cafeteria and devising a method of nutritional education, the energy intake and weight increased during the training period. However, the athlete could not maintain the BM throughout the competition. Therefore nutritional support methods to maintain BM should be considered.
