This study aims to clarify the relationship between scientific knowledge, life knowledge, and experience-based knowledge in sports nutrition support of sports coaches. Hence, we focused on sports magazines that attract the attention of sports coaches and feature many articles on nutrition, and thereafter, analyzed the information on nutrition.
As a preliminary finding, we determined that, in the 1950s, there was hardly any information on sports nutrition support due to severe economic conditions following the war. However, in the 1960s and 1970s, because of the decision to host the Tokyo Olympic Games, the opportunities for researchers to gather and disseminate information on scientific knowledge about nutrition increased. Thus, information on experience-based knowledge of sports coaches has also increased. This has been viewed as an attempt to utilize the collaboration between scientific knowledge and practice in sports nutrition support.
In the 1980s and 1990s, in sports nutrition support, advisors and experts have been disseminating information on scientific knowledge and life knowledge, a specific method of nutrition intake through meals. Unfortunately, information on experience-based knowledge concerning sports coaches has hardly surfaced. Therefore, in order for sports coaches to utilize scientific knowledge in sports nutrition support, it is necessary to verify and test the scientific knowledge against their own experience-based knowledge while referring to the other necessary knowledge from advisors and experts.
