GNSSを利用したスポーツデータ分析フレームワークの設計

抄録

  The analysis of sports data using GNSS has spread to the managers of high-performing soccer and rugby teams, but it has only received limited attention in other sports. This may be because the device and operating costs of GNSS receivers are high, and analysis and evaluation methods have not been well established. In this study, we created a framework for sports-data analysis, creating and formalizing methods of analysis and evaluation, without regard to cost. We first examined operations of rugby squads that regularly use GNSS data. For such teams, distance, speed, sprinting speed, acceleration, and deceleration are analyzed using GNSS data, and the results are used for training. Through the display of higher-level data for each player, their motivation for athletic training has improved. In addition, through combining GNSS data, heart rate, and vital and conditional data, the coaches can control the strength of the training and prevent injuries to the players. Furthermore, tracking data can be used together with video, and play style and play areas can mostly be confirmed in game scenarios. These results showed the frameworks that contribute to GNSS data to be physical training, motivation, prevention of injury, and game tactics. We also collected GNSS data for sport performers in field hockey, tennis, and triathlon, organized data around each of the four elements, and received an expert review. The framework was found to be able to confirm at a glance how GNSS data can help not only in rugby but also in field hockey, tennis, and triathlon to enable coaches and athletes to smoothly discuss performance.
