Why should high-intensity exercise be avoided in CMT patients?

• A. It can cause excessive fatigue and exacerbate muscle weakness.
• B. It improves endurance too quickly.
• C. It has no effect on fatigue.
• D. It only affects cardiovascular health.

Answer: (A)

High-intensity exercise is avoided in CMT because the combination of neuropathy and distal muscle weakness means the body has less reserve to handle strenuous effort. Pushing to high levels of exertion tends to cause excessive fatigue, can worsen existing weakness, and slow recovery or increase injury risk in the affected muscles. A safer approach focuses on moderate-intensity activity that builds endurance and strength without overloading the nerves and muscles, with gradual progression and ample rest. Some might think endurance would improve quickly or that fatigue isn’t affected, but fatigue is a central concern in CMT, and the benefits come from steady, controlled activity rather than pushing to high intensities. It’s not just about cardiovascular health—the impact on muscles and nerves is what drives the guidance.
