〔方法〕対象は成人男性16名｡スクワット、フォワードランジ（ランジ）、Drop Vertical Jump（DVJ）をKinect と三次元動作解析装置Vicon で同時に２回ずつ測定し、それぞれで算出した膝関節角度の相対信頼性と絶対信頼性を求めた｡
〔結果〕スクワットとランジ、DVJ の級内相関係数ICC（1、1）はKinect 0.79、0.85、0.62、Vicon 0.88、0.94、0,73であった｡系統誤差はみられなかった｡ICC（2、1）はスクワット１回目0.65、２回目0.61、ランジ0.75、0.79、DVJ0.77、0.79であった｡全ての動作に固定誤差を認めた｡
〔結語〕Kinect で算出した膝関節角度の再現性は高く、同一対象者の比較には有効利用できる可能性がある。しかし誤差の範囲の軽減に向け測定回数を増やすなどの対策を検討する必要がある｡
[Purpose] To investigate the relative reliability and absolute reliability of a 3-dimensional motion analyzer （Vicon） and a simple multiview motion capture device （Kinect）. [Subjects and Methods] Sixteen adult men were included in the study.Squats, forward lunges, and drop vertical jumps （DVJs） were measured twice simultaneously with the Kinect and the Vicon.Relative reliability and absolute reliability were calculated for the knee joint angles in each measurement. [Results] The intraclass correlation coefficients（ ICC）（ 1, 1） for squats, forward lunges, and DVJs were 0.79, 0.85, and 0.62, respectively, with the Kinect and 0.88, 0.94, and 0.73, respectively, with the Vicon. No systematic errors were observed. The ICC （2, 1）values were 0.65 and 0.61 for the first and second squats, 0.75 and 0.79 for the forward lunges, and 0.77 and 0.79 for the DVJs. Fixed bias was observed for all movements. [Conclusion] The knee joint angles calculated with the Kinect exhibited high reliability and may be useful for comparisons within the same participant. However, countermeasures such as increasing the number of measurements should be considered to reduce the error range.},
