OBJECTIVE: Changing gait speed is a common strategy to manipulate exercise intensity during physical exercise, but may elicit higher impact forces and consequent joint loading. Here we analyzed the effects of increasing walking velocity on plantar pressure and asymmetries in elderly with @entity626 ( @entity571 ). Our hypothesis was that the contralateral limb could receive higher loading compared to the @entity571 limb in the different walking speeds tested. METHODS: Twelve elderly with unilateral knee @entity571 walked at different self-selected speeds along a 10 m pass way stepping on an instrumented mat for measurement of plantar pressure at preferred, slow and fast gait speeds. Five steps were recorded for each speed. Plantar pressure data were compared between the speeds and legs. RESULTS: speeds were significantly different between them (p<0.05). Mean and peak plantar pressure increased when speed changed from slow to fast (p<0.05). Velocity of the center of pressure increased and the single stance time decreased when walk speed was increased (p<0.05). Any asymmetries were observed. CONCLUSION: Increasing gait speed from slow to fast in subjects with unilateral knee @entity571 significantly affected variables of plantar pressure, but asymmetries between committed and contralateral leg were not detected.
