What type of exercise is advised against for those with DMD?

For individuals with Duchenne Muscular Dystrophy (DMD), high-impact aerobic exercise is advised against primarily due to the potential for exacerbating muscle degeneration and injury. DMD is a progressive genetic disorder characterized by muscle weakness and loss, primarily affecting boys. The muscle fibers become increasingly fragile over time, and high-impact activities can lead to further muscle damage and accelerate the decline in muscle function.

Engaging in high-impact aerobic exercises can place excessive stress on already compromised muscle tissues, resulting in pain, increased risk of strain or injury, and can contribute to overall quicker progression of the disease. Therefore, it is crucial for individuals with DMD to avoid these activities and instead consider low-impact exercises that promote cardiovascular health without adding undue stress on their muscles.

Stretching programs, low-impact aerobic exercise, and strength training may all have benefits when carefully prescribed and monitored, as they can help maintain flexibility, strength, and overall health, provided they are tailored to the individual's capabilities and limitations. Thus, while some types of exercise can be beneficial, high-impact aerobic exercise is not suitable for those with DMD due to the risk of further muscle damage.
