Abstract(s)
This study compared the ground reaction forces (GRF) and plantar pressures between unloaded and
occasional loaded gait. The GRF and plantar pressures of 60 participants were recorded during unloaded
gait and occasional loaded gait (wearing a backpack that raised their body mass index to 30); this load
criterion was adopted because is considered potentially harmful in permanent loaded gait (obese
people). The results indicate an overall increase (absolute values) of GRF and plantar pressures during
occasional loaded gait (p < 0.05); also, higher normalized (by total weight) values in the medial midfoot
and toes, and lower values in the lateral rearfoot region were observed. During loaded gait the magnitude
of the vertical GRF (impact and thrust maximum) decreased and the shear forces increased more than
did the proportion of the load (normalized values). These data suggest a different pattern of GRF and
plantar pressure distribution during occasional loaded compared to unloaded gait.
