Growing athletes requires nutritional
support in individual local communities

"I want to ensure that food that aids physical activity is delicious," says Kumiko Ebi, explaining the objective of her study. She not only studies "food" for growing young athletes in local communities but also contributes to the development of young athletes through nutritional support to incorporate the concept of "local production for local consumption."

As a registered dietitian, Ebi has supported top Japanese athletes via "food" by, for example, taking charge of nutritional support for JOC-certified athletes at the Beijing Olympics. In the process, she renewed her awareness of the reality that most young athletes that will become the future of Japanese sports grow up in an environment without sufficient nutritional support. "It is young athletes in the middle of the process of building up their bodies that most require nutritional support." She has been continually searching for methods to enable stable nutritional support for young athletes in local communities.

"The daily nutrition of young athletes really depends on not only the athletes themselves but also on the support of coaches and families, etc.," Ebi says. To change the dietary environment for young athletes in local communities, she launched the Society to Promote Food and Sports ("Shokusupo") in 2010, in which teachers instructing physical education and extracurricular activities at junior and senior high schools, mainly in Shiga Prefecture and Kyoto Prefecture, voluntarily get together, and she has been supporting the society's activities since that time. At Shokusupo, the leaders present the reality and problems of their teams and clubs, while Ebi and graduate school students certified as registered dietitians provide nutritional instructions and advice. The aim is to disseminate the importance of "food" to local communities by gathering leaders with many achievements and broad influence from various schools and by having them play a pivotal role.

Starting out as a part of a research project at Ebi's laboratory, nutritional education provided to a Women's Softball Club at Hieizan High School in Shiga Prefecture turned out to be one of the successful cases. Under instructions from graduate students that are registered dietitians, players set individual targets such as an increase of muscle and the lowering of body fat percentage, and tried to improve their meals or eating habits. As a result, their attitudes toward eating, not to mention their physiques, changed. Ebi says, "As players communicated the nutritional instructions they received at school to their families, indirect intervention effects were a success." This is a good example where a virtuous circle was created where efforts toward "food" starting with leaders were handed down to athletes and then finally their families.

Shokusupo also concentrates on young leaders. "When leaders suggest dietary improvements to athletes, they face many difficulties, such as their own lack of knowledge or having to deal with the athletes' parents. To handle this, once a year an 'extended study meeting for leaders' is held to respond to such concerns."

Six years have already passed since Ebi started this initiative, and the number of participants in Shokusupo has increased every year. The range of nutritional guidance has been expanding to sports clubs at junior and senior high schools.

Among her initiatives, Ebi is also focusing on changing dietary environments for young athletes in local communities as nutritional support for junior high school students and female athletes.

For junior high school students undergoing drastic physical and mental changes amid the development of secondary sexual characteristics (puberty), "food" has a very important meaning. Ebi hopes that they can become able to think about "food" so as to improve their bodies by themselves. The graduate students involved also devised a tool that can serve as a start. "Sports nutrition sugoroku" enables athletes to gain knowledge on sports nutrition and the food materials that are available in their community. They are currently creating this system with the target of distributing it to all junior high school students in Shiga Prefecture.

In addition, young female athletes tend to have serious issues about food. Female athletes in their teens and 20s often display "Female Athlete Triad," in which low energy ingestion results in irregular menstruation or lowered bone density. "Competitiveness can increase when eating properly and following proper nutrition, but quite a number of female athletes reduce their intake of food, believing that they cannot improve their times or records if they are fat," Ebi says.

In addition, Ebi is concerned about the decreasing number of female students joining sports clubs. "The number of female students who are thin because they neither exercise nor eat properly is increasing, but surely such women can grow into adults that can play an active role in society?" Ebi worries about this and is hoping that a solution of sorts will appear, and has thus devised recipes to increase the nutritional intake of young women who enjoy eating and exercising. She also published a book, Joshibukatsushoku (Food for Female Athletes).

Some graduate students who studied sports nutrition have started a career in nutritional support for future Olympic athletes, much like Ebi did. "I feel that one of my main achievements in these six years is that I could help my graduate students—who once supported young athletes in their local communities—to develop into diet and nutrition support providers for world-class athletes," Ebi says.

Ebi is also engaged in training sports dietitians. Her efforts are sure to lead to the development of not only athletes that can support the future of sports but also the human resources to support these athletes.
