Kanagawa Prefectural Yokosuka High School
Kanagawa Prefectural Yokosuka Senior High School (Yokosuka High School: Yokosuka City Kanagawa, Principal: Eiji Tatara) and Nippon Telegraph and Telephone Corporation (NTT, Head Office: Chiyoda-ku, Tokyo; President & CEO: Akira Shimada) have collaborated on motion analysis research targeting sports teams' activities in the high school. Yokosuka High School and NTT found distinctive movements of the trunk and upper limb during swimming and on the load distribution of upper and lower limbs in the “set” position posture at the start of a sprint. These achievements were obtained in discussions based on the results of the motion analysis using NTT's own measurement system and technologies targeting the issues in which the students were interested during their own sports teams' activities in daily life. These case studies contribute to increasing the worth of data science and the training environment for sports analysts in the activities of high school sports teams.
Three members of the swimming team of Yokosuka High School presented their results at a poster session in EMBC2023 (*1), which is the largest international conference for convening academics, clinicians, industry, students, and researchers in the biomedical engineering and medtech communities. Three members of the field track team also presented their results at Global Link Singapore 2023 (*2), which is an international contest for junior and senior high school students, and won the Fine Work Prize.
Yokosuka High School, which was designated as a Super Science High School (SSH) (*3) by Japan's Ministry of Education, Culture, Sports, Science and Technology in 2016, has recently created a three-year curriculum of project-based learning to develop future leaders who can see issues from a global perspective, come up with solutions on the basis of scientific and logical thinking, and present them to the world. In its first-grade curriculum, Yokosuka High School encourages students to gain research knowledge and learn about research processes via their experience of research activities with researchers working in universities and research institutes. NTT has provided a research topic every year and supported Yokosuka High School's SSH activities since 2016.
Meanwhile, NTT has researched and developed motor-skill transfer technology that extracts knacks of motor skills by analyzing from the objective motor state expressed on the basis of biological signals such as electromyography and electroencephalogram. It then facilitates motor learning for beginners by directly transferring these knacks through sensory stimulations to help people to learn knacks of motion skills more efficiently. NTT has motion analysis technologies that use a measurement system synchronizing a motion capture system with electromyography sensors and force plates and sensory stimulations facilitating motor skills.
Yokosuka High School and NTT have collaborated on motion analysis research toward finding knacks of movements during sports teams' activities.

Yokosuka High School and NTT are continuing their research collaboration in the 2023/2024 academic year, delving deeper into their research theme. Moving forward, Yokosuka High School will utilize the knowledge gained from these case studies to further l improve the performances of their sports teams. NTT, on the other hand, will leverage the research results from this collaborative project to advance its expertise in sports analysis and motor learning technologies. Additionally, NTT aims to expand collaboration with various research partners, contributing to the development of the next generation of research talent.
