SPLYZA and Nippon Sport University Collaborate on AI Motion Analysis

In a groundbreaking initiative, SPLYZA Co., Ltd., located in Hamamatsu City, Shizuoka Prefecture, and Nippon Sport University (NSU), based in Setagaya, Tokyo, have signed a cooperative research agreement effective January 18, 2026. This partnership centers around the application of SPLYZA’s markerless 3D motion analysis application, ‘SPLYZA Motion’, which utilizes artificial intelligence (AI) technology.

Research Objectives and Responsibilities

The core of this research is to validate the efficacy of AI-driven high-precision motion analysis technology. Researchers will establish objective evaluation standards to verify the accuracy of SPLYZA’s unique analysis methods. The intent is to deepen insights into motion evaluation systems that can enhance sports performance and physical fitness.

Nippon Sport University, leveraging its specialized knowledge, will assume the role of evaluation leader for the analysis values derived from this research. They will oversee the comparative verification process between SPLYZA's proprietary technology and the established objective evaluation criteria, as well as the evaluation of the data and the creation of resultant reports. On the other hand, SPLYZA is tasked with providing the necessary proprietary analysis technology and improving their techniques based on the verification results.

Comments from Key Researchers

Associate Professor Mitsuo Otsuka from Nippon Sport University expressed, “The advancement of motion analysis using AI is a vital topic for the future of sports science. Participating in this research is immensely significant, and I am confident that the outcomes will contribute not only to competitive performance but also to the broader domain of physical science.
