Knowing how age and sex affect trunk motion and energy conservation can help clinicians decide when and in whom to intervene with physiotherapy to prolong functional mobility. Methods: A large sample of 138 able-bodied males and females in the age-categories 20–39 years, 40–59 years, 60–69 years, 70–79 years, and 80–89 years received a full-body 3D gait analysis. A two-factor ANOVA was performed to examine the effect of age and sex and their interaction on 3D trunk kinematics and positive mechanical work of the lower limbs, head-arms-trunk (HAT) segment and whole body. Results: A significant decrease in walking speed was only found in those above 80 years (~.05 nm/s, p <.006), while changes in 3D trunk kinematics were observed earlier. From 60 years on, trunk rotations decreased (~ 2–3°, p <.05), from 70-year frontal pelvic motion (~ 4°, p <.001), and from the age of 80 years sagittal thorax motion (~ 1–6°, p <.05). There were only small aging effects for mechanical energy demands that were more pronounced in females, showing decreased of HAT contributions (p =.020). Furthermore, age-related differences in trunk kinematics are highly dependent on sex whereby age-related changes were observed sooner in females than males in all three planes of motion. Conclusions: Age-related differences in 3D trunk kinematics are observed from 60 years onward and increase with age. Age-related stiffening of the trunk did not seem to affect the body’s total mechanical work. Importantly, our data did show a stark contrast between males and females, indicating that training to prolong mobility should be tailored to sex. Future research should include sex-matched data when examining normal age and pathologic gait decline.
