Intersegmental transfer of energy improves gait efficiency by passively passing kinetic energy between body segments through what?

• A. Muscles only
• B. Joints
• C. Skin
• D. Visual cues

Answer: (B)

Intersegmental energy transfer in gait happens through the joints that connect body segments. The joints act as constraints that link adjacent segments, so as one segment changes speed or direction, its motion can passively transfer kinetic energy to the next segment via angular momentum exchange at the joint. This exchange occurs because the segments and joints form a coordinated, multi-link system, allowing energy to move without requiring active muscle work at every step. That passive transfer helps conserve energy and makes walking more efficient, even though muscles still drive the overall motion. Skin or visual cues don’t carry or exchange kinetic energy between segments, so they don’t contribute to this energy transfer mechanism.
