Why do CMT patients need to adjust exercise intensity?

• A. They have higher energy requirements due to musculoskeletal inefficiencies
• B. They recover quickly after workouts
• C. They prefer longer workouts
• D. They don't have fatigue

Answer: (A)

The main idea is that Charcot–Marie–Tooth disease makes activity more energetically costly. Because nerves and distal muscles are weaker and movements become less efficient, the body uses more energy to perform the same task. That higher energy cost means you can reach a given effort with less actual work, so you have to adjust exercise intensity to avoid overdoing it, protect joints and nerves, and manage fatigue. In practice, this means starting at a lighter intensity, monitoring how hard it feels (using RPE or the talk test), and progressing gradually. Other options don’t fit because recovery speed, a preference for longer workouts, or the absence of fatigue aren’t reliable indicators for this condition. Fatigue tends to be a real concern, and the metabolic cost of movement is usually higher, not lower.
