Université Paris Descartes researchers studied transgenic SMA-like mice for 10 months. The mice participated in various activities, including running slowly or swimming intensely.

 

Here are six observations:

 

1. The mice demonstrated enhanced muscle resistance to activity-induced damages as well as better aerobic performance.

 

2. The study found motor neurons benefited from swimming and running.

 

3. Swimming protected the intermediate and fast motor neurons in the mice and improved the cross-sectional area of large muscle fibers.

 

4. Running protected the slow motor neurons and improved the cross-sectional area of intermediate muscle fibers.

 

5. SMA has no cure and researchers have not yet studied the effect of exercise on SMA patients.

 

6. The researchers concluded physical exercise could prove beneficial for SMA patients if they follow a specific exercise regimen so as not to expedite the neurodegeneration process.
