Experimental Research on Plantar Pressure Distribution Law of Young Women

Objective:Using the means and methods of sport biomechanics and depending on Belgian Footscan insole plate system among female college students,the paper tests the maximum value of plantar pressure in walking and jogging with normal gait,toe and toe in to explore the motion characteristics of gaits.This paper aims to provide the basis for function evaluation,orthopedic sports shoes design and sports prosthesis design.Methods:450 young women from Shijiazhuang are randomly selected as samples to make comparisons between groups by One- Way ANOVA analysis.Results:Subjects with normal posture during walking have their foot maximum force position in the second metatarsal of palm while the abnormal walkers in the heel;during jogging,those with normal posture have their foot maximum force position in the second metatarsal,while the abnormal joggers,in the first metatarsal and the second metatarsal.Conclusion:heel peak of abnormal subjects is greater than that of the normal walkers and the differences are statistically significant(P 0.01).Because of the poor transition of plantar force from the heel to the whole foot,then to the palm,then the lack of cushioning effect,the heel bears pressure.Walking with abnormal gaits leads to instability for the greater pressure of heel than that of the palm;in jogging,the pressure of the first metatarsal and the second metatarsal is greater than that of the normal with statistically significant differences.
