Morphology-related foot function analysis: implications for jumping and running

Barefoot and shod running has received increased attention in recent years, however, the influencee of morphology-related foot function has not been explored. This study aimed to investigate the morphology-related jumping and running biomechanical functions in habitually barefoot and shod males. A total of 90 barefoot males (Indians) and 130 shod males (Chinese), with significant forefoot and toes morphology differences, participated in a vertical jump and running test to enable collection of kinematic and kinetic data. The difference of pressure distribution in the hallux and forefoot was shown while jumping and running. The unrestricted forefoot and toes of the barefoot group presented flexible movement and leverage functions to expand the forefoot loading area during performance of the two tasks. Findings related to morphology functions, especially in the forefoot and toe may provide useful information for footwear design.
