COMPARISON OF SHOCK ATTENUATION BETWEEN SPORT SHOES WHEN LANDING FROM VERTICAL JUMP

Abstract

Many sports require particitlanls to perform jump landing. However, the peak impact force at landing was about 7.1 body weight, which might lead to injury. Basketball shoe, running shoe, cloth sport shoe, r,nd barefoot were selected in the present study. The purpose of this study was to investigate the impact when landing from vertical jump. Eleven subjects with no reported lower limb injur:os were recruited. After warm-up session, each subject performed 12 jumps. The sport shoes were assigned to subjects randomly. In ANOVA analysis, significant diHerence only '3xisted in time to first impact peak force, F=8.99, p=.001. The results showed that muscles cl ankle joint (0.0688s) could not react to first impact peak force (0.0174s). Same as previous studies, results were affected by subjects' perception. In conclusion basketball and running shoes provided better shock attenuation in rearfoot.
