When obese adults with type 2 diabetes exercise hard for 12 weeks, five days a week, their muscle cells start to fix broken mitochondria—making them longer and less round, which might help the cells work better.

1602-P: Exercise Training Reverses Skeletal Muscle DRP1 Hyperactivation and Improves Respiratory Capacity in Patients with Type 2 Diabetes

Randomized Controlled Trial

Human

This study showed that when obese adults with type 2 diabetes exercised hard for 12 weeks, five days a week, their muscle cells’ energy factories became longer and less round because a problematic protein (DRP1) calmed down — exactly what the claim says.

Similar Assertions

When obese adults with type 2 diabetes exercise regularly, their muscle cells’ energy factories become longer and less round, which is a good thing—even if the usual control switches in the cell don’t change.
