When human beings take the posture of standing upright, it is necessary to split the weight on their faces of the soles, to support and balance themselves in order to keep the standing posture. This study aims at making clear the characteristics of splitting their weight within the sole faces under the various conditions in order to predict and prevent when inability comes for standing upright according to aging. Distribution of pressure within sole faces has been measured, choosing three healthy subjects who do not do any sports daily and three athlete subjects doing sports daily. When they stand on both legs, when they stand on each one of their legs, both with their eyes closed and with their eyes open, the measurement was done. Cross sections of groups of crus muscles were measured using the MRI, and the measurement results of the characteristics of splitting body weight were examined. As a result of this experiment, (1) When subjects stand upright with their eyes closed, the shared load in the front part of sole increases. (2) When subjects stand upright on each one of the legs with their eyes closed, the shared load ratios of athlete subjects are less in their increase than those of healthy subjects who do not do any sports daily. (3) To keep standing upright posture, crus muscle operation influences greatly.
