Reducing energy waste during movement improves which concept?

• A. Momentum
• B. Velocity
• C. Movement economy
• D. Inertia

Answer: (C)

Reducing energy waste during movement improves movement economy because it focuses on how efficiently the body uses energy to move. Movement economy is about the energy cost of moving at a given speed or distance. When you minimize wasted movements, unnecessary muscle work, or inefficient technique, you use less oxygen and fuel for the same pace, so performance can be maintained longer with less fatigue.

Momentum, velocity, and inertia are more about the physics of motion: momentum is mass times velocity, velocity is speed, and inertia is the resistance to changing motion. While technique can influence speed or the way momentum is applied, those properties aren’t directly improved by reducing energy waste in the same way as movement economy is.
