Aim. We wanted to study biomechanical adjustements of plantar support in obese compared to normal-weight subjects during gait cycle by a force platform.
Methods. We recorded the gait cycle using a force plat in 19 normal-weight and 20 obese women, excluding preliminarly subjects with left-hemisomus dominance, spine, inferior limbs and sensory organs injuries.
Results. The significant anthropometric differences were expected. Obese women had a significant increase on the plantar support time and on the fulfilment time of gait cycle in toto. The analysis of each plantar imprint showed that prolonged gait-cycle times in obese than normal weight subjects depend by significant increase of support in the middle phase for both plantar imprints.
Conclusion. Obese women realize a slower gait-cycle compared to normal-weight women, pressing particularly the middle phase of support of both feet; a slower gait-cycle agrees more stability and body control, but it induces a functional over-load on the feet developing in chronic injuries.
