What are exercise considerations for SMA?

• A. Avoid fatigue-induced weakness, monitor respiratory function, and accommodate joint instability.
• B. Push through fatigue to build endurance.
• C. Ignore joint instability during activity.
• D. Increase high-intensity workouts to maximum daily.

Answer: (A)

In SMA, exercise is managed to protect weakened muscles, keep breathing function safe, and support joints that may be unstable. Because muscle weakness can quickly lead to fatigue and respiratory muscles can be affected, a plan favors pacing, submaximal effort, and plenty of rest—not pushing to exhaustion. Monitoring respiratory function helps catch signs of breathing strain early, so activities can be adjusted. Joint instability is common, so exercises are chosen with stability in mind, avoiding movements that put undue stress on the joints and using supports or modifications as needed. This is why the best choice emphasizes avoiding fatigue-induced weakness, watching respiratory function, and accommodating joint instability. Pushing through fatigue, ignoring joint instability, or increasing high-intensity workouts to maximum daily would place excessive demand on fragile muscles and the respiratory system and increase injury risk.
