Abstract
Joint kinetic analysis is dependent on accurate link-segment models. Considering the current default model may not account for female segment anthropometry, we sought to develop and test sex-specific biomechanical models. We hypothesize that a sex-based biomechanical model would produce a significant alteration in hip, knee, and ankle joint moments compared to default model for females, but not males. Fourteen female and 18 male participants had hip, knee, and ankle joint moments quantified during running (4.0 m/s) using both a default and sex-based (both male and female) biomechanical model. Peak hip, knee and ankle joint moments were submitted to paired t-tests to compare the default and sex-based model measurements. Contrary to our hypothesis, both male and female sex-based models altered lower limb joint moments compared to the default model. Both the male and female sex-based model produced larger hip (p < 0.011; p < 0.032), but smaller ankle joint moments (p < 0.023; p< 0.001); while the sex-based knee joint moments were smaller for males (p < 0.036) and larger for females (p < 0.049). The current findings support the need for sex-based biomechanical models.
