Values: mean ± SD, Rep ANOVA: repeated measures ANOVA, *: p<0.05, **: p<0.01. Post hoc tests. a*: significant difference versus straight (p<0.05) a**: significant difference versus straight (p<0.01). b*: significant difference versus straight (p<0.05) b**: significant difference versus straight (p<0.01). c*: significant difference versus ipsilateral (p<0.05) c**: significant difference versus ipsilateral (p<0.01). † Complete trunk and lower limb extension, with the COG in the highest position. ML: mediolateral. ML distance was standardized with the distance of both 5th metatarsal heads. AP: anteroposterior. AP distance was standardized with the distance of lateral malleolus to the 5th metatarsal head
