Which term describes completing a movement in an energy-saving or efficient way?

• A. Endurance
• B. Pace
• C. Efficiency
• D. Movement economy

Answer: (D)

Movement economy is about how efficiently the body uses energy to complete a movement. It describes the energy cost required to perform at a given speed or workload. When movement economy is high, you can finish the same movement with less energy, meaning less fatigue and better performance over time. This is exactly what “energy-saving or efficient movement” refers to.

In practice, a runner or cyclist with good movement economy uses less oxygen or fewer calories for a given pace because their technique, biomechanics, and conditioning minimize wasted energy. Endurance is about how long you can sustain activity; pace is the speed you move at; efficiency is a broader idea of getting more output from the same input, but movement economy is the specific term used to describe how economically the movement itself is performed.
