Exercise fixes broken energy factories in muscles of people with diabetes
1602-P: Exercise Training Reverses Skeletal Muscle DRP1 Hyperactivation and Improves Respiratory Capacity in Patients with Type 2 Diabetes

Surprising Findings
Exercise improved mitochondrial structure and energy production without activating PGC-1α or AMPK, two proteins believed to be central to mitochondrial adaptation.
For decades, scientists thought PGC-1α and AMPK were the main drivers of exercise-induced mitochondrial changes—this study shows a completely different pathway is at work.
Practical Takeaways
Do 60 minutes of aerobic exercise at 80–85% of your max heart rate, 5 days a week, for 12 weeks to potentially improve insulin sensitivity and body composition.

Doing regular cardio workouts like walking, running, or cycling helps your muscles use sugar better, which keeps your blood sugar in check and makes it less likely you'll get type 2 diabetes.
After doing supervised aerobic exercise like walking or cycling for 12 weeks, obese adults with type 2 diabetes get better at using oxygen to make energy in their muscles—especially through one key energy pathway—and might also improve a couple of other related energy systems.
If obese adults with type 2 diabetes do 12 weeks of guided cardio workouts like walking or cycling, their bodies get better at using insulin to manage blood sugar.
If obese adults with type 2 diabetes do supervised aerobic exercise like walking or cycling for 12 weeks, they’ll likely lose body fat and gain muscle.
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.
