Which statement best describes the metabolic impact of resistance training in conditioning?

• A. It decreases calorie expenditure.
• B. It has no effect on metabolism.
• C. It contributes to higher calorie expenditure.
• D. It only affects muscle size without metabolic effects.

Answer: (C)

Resistance training boosts energy expenditure. Lifting against resistance pushes your muscles to work, so calories are burned during the workout. Afterward, the body remains in a higher metabolic state for several hours as it repairs and adapts the muscle fibers, which is the afterburn effect. Over time, increasing lean muscle mass raises resting metabolic rate, so you burn more calories even at rest. These combined effects mean resistance training contributes to higher overall calorie expenditure in conditioning. It isn’t true that it has no metabolic effect, or that it only changes muscle size; the metabolic impact includes more calories burned during and after exercise, plus a higher resting energy use.
