Efeito do calçado sobre o impacto em tarefa de salto e aterrissagem

Abstract

Impact forces are considered a risk factor for injuries during jump-landing tasks. Rebound shoes are advocate to reduce impact forces with potential use in training sessions and also in rehabilitation programs. However, most of commercial rebound shoes have not been tested regarding the ability to dissipate impact forces. Here we set out to determine the capacity of a rebound shoe in attenuating impact during a jump-landing task. Fifteen physically active women (average age 23 years, height 1.64 m and body mass 63 kg) and not trained for jump-landing tasks. Vertical ground reaction force impact peak, time to peak, and asymmetries were determined during vertical jump-landings wearing a commercial rebound shoe and a control running shoe. Paired t-tests compared the shoe conditions and right vs. left leg. The rebound shoe reduced the vertical ground reaction impact force with slight asymmetry between the legs. The rebound shoe showed a longer time to peak in both the legs. The rebound shoe tested can be useful to reduce impact during vertical jump-landings, with potential applications for training and insertion in rehabilitation programs requiring lower impact to the lower extremity.
