 note = {スポーツの効果的な選手指導を目的とし，センサなどのデータ分析を用いた定量的かつ客観的な選手のパフォーマンス評価が期待されている．従来，運動強度や速度などの個人パフォーマンス指標の導入は進んでいるが，同様に重要とされる組織的パフォーマンスにおいては，映像観察などに基づいており，実用的な分析手法がなかった．そこで本研究では，センサで計測した2者の加速度データから潜在的情報伝達を推定する移動エントロピーを用いた分析手法を提案し，サッカーU-18チームを対象として練習試合中の選手の加速度データを収集し，提案手法の妥当性・有用性を評価した．評価の結果，指導者が抽出した組織として意図する攻撃ができているシーンにおいて，チーム間の情報伝達が統計的有意に高まることを確認し，集団スポーツにおける選手間の駆け引きを定量化できる見通しを得た．, The quantitative and objective evaluation of player's performance by applying data analysis is needed to achieve effective sports coaching. In conventional, personal performance index such as exercise intensity and moving speed is introducing to team sports. However, evaluating organizational performance that is one of the most important factors in team sports is mainly based on video observation, and the evaluation is not practical for sports coaching. In this research, we propose a novel data analysis method by using transfer entropy to estimate potential information transmission between two players from the two series of acceleration data, and evaluate validity and usefulness of our method through the experiment on the U-18 football team. In result, we confirmed that the information transfer between the team in the specific scene that the team coach extracted as organized situation statistically significantly increased. This result suggests that our proposed method realize to quantify tactics in team sports.},
