概要
概要（英）: This study aimed to evaluate the estimation method of ground reaction force (GRF) and center of pressure (CP) of support foot during running as Hoga-Miura (2022) on race walking. Seven Japanese male race walkers participated to the experiment of present study during training camp of race walkers, running along 50m-walkway on their own speeds for their recovery training with running. Force platforms (1000Hz) which were mounted on the walkway measured GRF and CP during running. Vicon-system (250Hz), set up on the walkway, captured three dimensional coordinates of body marks in order to calculate the position of the center of gravity of whole body (CG) and other parameters of kinematics and kinetics. From the estimated center of pressure of support foot at the midpoint of their sole (eCP), the acceleration of CG and the angular momentum about CG, the ground reaction force (eGRF) was estimated by using the methods of Hoga-Miura (2022). To evaluate the influence of estimation to other valuables, joint torques in lower extremities were compared between measured (TRQ) and estimated (eTRQ). Statistical parametric mapping (SPM) were used to conduct non-parametric paired t-test between measured and estimated variables (GRF vs eGRF, CP vs eCP, TRQ vs eTRQ). Along with the practical quick feedback methods on the training of elite athlete in Japan, this study focused on the parameters in sagittal plane. CP and eCP were significantly different during the almost entire support phase (p < 0.05). Also, GRF and eGRF were significantly different during the almost entire support phase (p < 0.05) both in anterior-posterior and vertical component. However, in the joint torques at ankle and knee in sagittal plane (about lateral-medial axis), there were not significant difference between TRQ and eTRQ during almost entire support phase.
