To provide an analysis device which can present feedback information for controlling the quality of a ball.SOLUTION: An analysis device comprises: a position information acquisition unit which acquires position information of a body portion of a subject in a pitching motion; a parameter acquisition unit which acquires a parameter about a ball pitched by the subject and a parameter about a plurality of segments of the subject; an angle calculation unit which calculates angles of a plurality of joints of the subject in the pitching motion; a torque calculation unit which calculates torque acting on the joint of each segment in the pitching motion; a pattern calculation unit which calculates a cooperation pattern between the joints of the subject in the pitching motion on the basis of the angle of each joint in time-series and each torque in time-series; and an output control unit which outputs feedback information for the pitching motion of the subject on the basis of the similarity between the calculated cooperation pattern and one or more reference patterns associated with the quality of the ball.SELECTED DRAWING: Figure 16 【課題】ボールの球質を制御するためのフィードバック情報を提示することが可能な解析装置を提供する。【解決手段】解析装置は、投球動作時における被験者の身体部位の位置情報を取得する位置情報取得部と、被験者が投げるボールに関するパラメータと、被験者の複数のセグメントに関するパラメータとを取得するパラメータ取得部と、投球動作時における被験者の複数の関節の角度を算出する角度算出部と、投球動作時において各セグメントの関節に作用するトルクを算出するトルク算出部と、時系列の各関節の角度と、時系列の各トルクとに基づいて、投球動作時における被験者の関節間の協調パターンを算出するパターン算出部と、算出された協調パターンと、ボールの球質と関連付けられた１以上の基準パターンとの類似度に基づいて、被験者の投球動作に対するフィードバック情報を出力する出力制御部とを備える。【選択図】図１６
