What is the expected effect of exercise training in COPD patients?

• A. It leads to energy conservation and improved muscle function
• B. It worsens dyspnea
• C. It causes weight loss
• D. It has no effect

Answer: (B)

Regular exercise training in COPD improves how efficiently the muscles use energy. With training, skeletal muscles increase oxidative capacity, mitochondrial density, and capillarization, so everyday activities require less ventilatory effort. This means the same tasks can be done with less breathlessness, and energy is conserved during activity. As a result, dyspnea tends to improve rather than worsen, and muscle function and endurance gains are common. Weight changes aren’t the primary or guaranteed outcome—training helps preserve or even increase lean mass if nutrition supports it, rather than causing weight loss on its own.
