Why is exercise considered controversial for children with Duchenne Muscular Dystrophy?

Exercise for children with Duchenne Muscular Dystrophy (DMD) is controversial primarily because of the condition's impact on muscle health and function. In DMD, the muscles progressively weaken due to the absence of dystrophin, a protein that is crucial for maintaining the integrity of muscle fibers. This weakness necessitates a careful approach to exercise.

Aggressive strengthening activities can lead to overworking the muscles, which may cause further damage rather than benefit. This is because the muscle fibers in children with DMD are already compromised, and excessive strain can accelerate muscle degeneration. Therefore, while some exercise is beneficial for maintaining mobility and overall health, it must be balanced carefully to avoid overexertion.

The correct choice highlights the need for moderation in exercise routines for children with DMD. This nuanced understanding is essential in managing the condition effectively, emphasizing that while some physical activity is necessary and can be protective, it should not be intense or excessively strenuous to avoid complications associated with muscle breakdown.
