What is the consequence of intersegmental energy transfer on the metabolic cost of gait?

• A. Eliminates completely
• B. Increases
• C. No effect
• D. Reduces

Answer: (D)

Intersegmental energy transfer uses the way body segments exchange energy through joints and inertial coupling during gait. When one segment’s motion helps drive another, the muscles don’t have to provide all the work themselves, so the total positive work that muscles must perform is reduced. This reuse and redistribution of energy lowers the metabolic cost of walking or running, making the overall energy expenditure smaller per step. If the transfer is well-coordinated, more energy is saved; if it’s poorly coordinated, the cost can rise, but in typical gait it tends to reduce energy cost.
