Knowledge Structuring of Skilled Sports Trainers - For Correct Movement to Prevent Disability and Promote Progress

Abstract: Japan has an aging population with a declining birthrate, and the social burden of nursing care is increasing. In this context, it is becoming increasingly important to make exercise a lifelong habit, and to prevent disability and promote progress through appropriate movement. To help achieve this, physical activity instructors, such as sports trainers, physical therapists, and sports coaches in various sports disciplines, monitor the client's posture, movement, and condition, including motor images, and provide voice and muscle and myofascial interventions to solve problems. However, because the knowledge of physical activity instructors is vast and tacit, the transfer of knowledge to other instructors with whom skilled instructors collaborate may not proceed smoothly, leading to poor performance, such as inconsistent instruction within the instructional team. In addition, face-to-face interventions are time-limited and require the client to physically visit the physical movement instructor. Therefore, although physical intervention is difficult, AI could improve the performance of the physical activity instructor team if even a portion of the verbal instruction could be implemented. In this study, we proposed a new data knowledge structuring method to improve the performance of the physical activity instructor team by comprehensively structuring the tacit knowledge they have about verbalization, allowing the AI to perform verbalization within the range that can be read from the images, and improving the knowledge based on the results. The results of the study showed that the AI can improve the knowledge by using the results of the wordings. As a result, a part of the knowledge that had not been told by skilled users was extracted, and the effectiveness of the proposed method was confirmed.
