GROUND REACTION FORCES AND PLANTAR KINETICS OF ROPE SKIPPING IN DIFFERENT SPORT SHOES -A PILOT STUDY
Keywords: Biomechanics, jump rope, landing, physical activity
AbstractThe purpose of this study was to investigate the ground reaction forces and plantar kinetics of different rope skipping skills with different sports shoes. One male elite rope skipper was instructed to skip rope with four skills and with four shoes. The skills included single bounce, double under, triple under and alternative step. The Pedar Mobile system was used to collect plantar pressure information beneath the foot inside the sports shoes. Vertical ground reaction forces (VGRF) of each skip were measured on a force platform. The mean values of each group were calculated for comparison. It was found that the VGRF is greater for triple under (-2.8 times SW on right leg), moderate for double under (-2.5 times SW on right leg), and lower for single bounce (-2.0 times SW on right leg). During, landing, the peak pressure mainly occurred at the metatarsal heads and hallux.
