Efeitos agudos da corrida na sensibilidade, pressão plantar e estabilidade corporal de corredores recreativos

Abstract

Physical exercise has acute and chronic on foot neuromechanics. The acute effects of running may involve changes in plantar sensitivity and plantar pressure distribution. These variables influence stability during standing. In this study, we observed plantar sensitivity increases in the acute assessment after running, but effects are not maintained 30 minutes after exercise is finished. This change in sensitivity contributes to a variation of sensitivity and pressure between the foot regions, and between the moments pre, post zero, 15 and 30 minutes after run. Plantar pressure decreases in the regions where sensitivity is better, and increases where the sensitivity is worse. These results were found by evaluating data from 11 recreational runners during a 5 km run on a treadmill without significant effects of fatigue. Nylon monofilaments were used for the evaluation of sensitivity and plantar pressure and center of pressure data were evaluated with computerized baropodometry system.
