Abstract Background One of the major public health problems of the 21 st century is obesity. Baropodometry is commonly used to determine specific loads on the plantar surface of the foot and the comportment of the body center of pressure (CoP). To evaluate the redistribution of the baropodometric parameters: static and dynamic plantar pressures and antero – posterior CoP, by decreasing body weight. Methods A sample of 43 subjects (24 male, 19 female) participated in the study. A hypocaloric diet was designed with the aim to reduce their body weight. The baropodometric exam was performed in two occasions: weight 1 – Session 1 and weight 2 – Session 2, when they had lost between 12 and 18 kg. The foot was divided in 9 areas: heel, midfoot, 5 metatarsal heads (MTHs), Hallux, 2-5 toes. The Footwork® pressure platform was used to carry out the evaluation. Results Subjects reduce an 11.59% their mean weight. Foot pressure decrease was statistically significant between the first and second measurements (p < 0.05). For the static on the Hallux, 2 nd MTH, 3 rd MTH, 5 th MTH and heel, while for the dynamic the pressure decreases on the whole study areas except on the 2 nd and 5 th toes. For the CoP, a notable posterior displacement was observed. There were no gender differences.Conclusion We can conclude that weight loss affected positively to both plantar pressures and CoP, since statistically significant changes were observed in the baropodometric parameters between the two times studied.
