Implication

Exploratory study examines kinematic and kinetic changes in macaques walking on varied pole diameters, suggesting substrate geometry shapes gait mechanics.

Key Points

This research aims to explore how pole diameter affects the walking mechanics of Japanese macaques.
Examined four trained macaques walking on metal poles of three different diameters.
Analyzed ground reaction forces, joint kinematics, and center of mass dynamics.
Compared walking on narrow and wide poles to flat-surface locomotion.
Macaques showed no significant differences in walking speed or stance duration across pole diameters.
Only modest differences in center of mass and stride length on narrower poles were observed.
Mechanical energy recovery remained consistent between pole and flat-surface walking.
