Is it advisable to do exercise when affected by Duchenne muscular dystrophy? Which activities would you suggest and how intense should they be?

For individuals living with Duchenne muscular dystrophy, physical activity is generally recommended to maintain joint flexibility and mobility, provided it is low-impact and carefully monitored. While high-intensity exercise can cause muscle damage, gentle, consistent movement is essential for managing the progression of Duchenne muscular dystrophy and improving overall quality of life.

Is physical activity safe for those with Duchenne muscular dystrophy?

There is a common misconception that movement should be avoided entirely to prevent muscle fatigue. However, clinical consensus suggests that sedentary behavior can accelerate contractures and muscle weakness in patients with Duchenne muscular dystrophy. The goal of any exercise program is not to build bulk or increase maximum strength, but to maintain range of motion and cardiovascular health. Always consult your neuromuscular specialist before beginning any new activity, as the specific stage of Duchenne muscular dystrophy will dictate the intensity and type of movement that is appropriate.

Which types of activities are recommended for Duchenne muscular dystrophy?

Low-impact, non-weight-bearing activities are typically the gold standard for individuals with Duchenne muscular dystrophy. These exercises minimize the stress on fragile muscle fibers while promoting circulation and joint health. Recommended activities include:

• Hydrotherapy or swimming: Water provides buoyancy that supports the body, allowing for movement with significantly less gravity-induced strain on muscles.


• Gentle stretching: Daily, supervised stretching is crucial to prevent the development of contractures, particularly in the ankles, knees, and hips.


• Passive range of motion exercises: In later stages of Duchenne muscular dystrophy, caregivers or therapists can assist with moving limbs to keep joints supple.


• Yoga or Tai Chi: Modified versions focused on breath control and slow, rhythmic movement can improve mood and body awareness.

Which activities should be approached with caution?

High-intensity and eccentric exercises—those that involve lengthening the muscle under tension—are generally contraindicated for Duchenne muscular dystrophy. Activities such as heavy weightlifting, long-distance running, or contact sports can lead to micro-tears in the muscle fibers, which, due to the lack of dystrophin, the body cannot effectively repair. This can lead to increased inflammation and a faster decline in muscle function. Listen to your body; if an activity causes significant soreness, fatigue, or muscle cramping, it is likely too intense.

How can I safely manage an exercise program?

Starting an exercise program should always be a collaborative effort involving your physical therapist and neurologist. Follow these principles for safe participation:

1. Pacing: Use the "24-hour rule"—if you feel more fatigued or weaker 24 hours after an activity than you did before, the intensity was too high.


2. Medical Clearance: Ensure your cardiac health is monitored, as Duchenne muscular dystrophy can affect the heart muscle, and exercise must be balanced with cardiac safety.


3. Consistency over Intensity: Short, frequent sessions (e.g., 10-15 minutes) are far more beneficial than sporadic, high-effort workouts.


4. Adaptation: On days when fatigue is high, prioritize gentle stretching or breathing exercises over active movement.

Next steps

• Schedule an evaluation with a physical therapist who has specific experience with neuromuscular conditions.


• Connect with the 38 community members on DiseaseMaps.org to share experiences regarding adaptive exercise programs.


• Ask your neurologist about a referral to a hydrotherapy center or a specialized pediatric rehabilitation program.


• Keep a daily log of activity and fatigue levels to help your care team adjust your routine as Duchenne muscular dystrophy progresses.
