Outline of Final Research Achievements

The aim of this study was to diffuse the measuring method of rotation angle of hip joint during upright position by using a load oscillometer with a rotation angle measuring tool. Also the aim of this study was to establish the evaluating systems on the abilities of posture control and physical exertion, by the trajectories of hip rotation angle and load oscillation acquired during active exercises. This evaluation method serves to easy evaluation of movement accuracy and athletic ability focusing on tracking changes in forms and angles of dynamic load oscillation. Data were collected from nearly 1000 people ranging from top athletes to ordinary people from fiscal 2012 to fiscal 2015. A close examination on the trajectory changes of shapes and rotation angles revealed that there was one side dominance in lower limb movements and characteristics in each athletic event. The factors which affected the accuracy of bodily movement including fatigue were discussed.
