b, slope adjusted for effect of all other variables in the model; U, proportion of unique variance explained by variable; CB,L, proportion of common variance shared by body mass and lower limb length; UB+UL+CB,L, proportion of variance explained cumulatively by the body mass and lower limb length; H-flex, peak hip flexion moment; H-ext, peak hip extension moment; K-flex, peak knee flexion moment; K-ext, peak knee extension moment; A-plant, peak ankle plantarflexion moment; A-dors, peak ankle dorsiflexion moment;
* p < 0.05;
** p < 0.01;
*** p < 0.001.
athe effect of particular variables is shown only for models that explain significant portion of variation in joint flexion angle.
