However, due to the large number of variables, it is difficult to evaluate the symmetry of the lower limb movement by comparing data from the six joints of the left and right lower limbs. In kinematic analysis of the transition from sitting to standing, the angles of the three joints of the lower limb are often measured. In this paper, we propose a method that uses the femoral and tibial elevation angles to quantitatively evaluate the symmetry of lower limb movement during the transition from a sitting position to a standing position. Our results suggest laterality of toe grip strength and the front foot toe grip strength is stronger than the rear foot toe grip strength in Kendo players. We found that the front foot toe grip strength was significantly stronger than the rear foot toe grip strength. All players used their right foot as the front foot. We then extracted the maximum value of toe grip strength from the three measurements on each side and calculated the ratio of toe grip strength to body weight (%). We measured toe grip strength three times on each side. The participants completed a questionnaire to determine which foot the participants used as their front and rear foot while standing in Kendo. In total, 15 male college Kendo players, who had no disability or pain in their feet, were included in the study. The purpose of this study was to determine whether unilateral dominance exists in toe grip strength in Kendo players using a toe grip dynamometer.
