What is an important consideration for exercise in children with Duchenne muscular dystrophy?

In the context of children with Duchenne muscular dystrophy (DMD), it is crucial to avoid eccentric contractions during exercise. Eccentric contractions, where muscles lengthen while under tension, can lead to increased muscle damage and further progression of muscle weakness in these children. DMD is characterized by the degeneration of muscle fibers, and eccentric exercise has been shown to exacerbate this condition, leading to muscle breakdown, inflammation, and deterioration, rather than improvement.

Focusing on appropriate exercise regimens for children with DMD often involves low-impact activities that minimize strain on the muscles rather than aggressive strengthening, which may be counterproductive. Therefore, the emphasis is placed on maintaining functional mobility and optimizing overall health and well-being without necessarily pushing the muscles to their limits or employing techniques that could lead to harm. Hence, the consideration to avoid eccentric contractions is a key element in managing exercise programs for children affected by this condition.
