The Study

The impact on glycemic control through progressive resistance training with bioDensityTM in Chinese elderly patients with type 2 diabetes: The PReTTy2 (Progressive Resistance Training in Type 2 Diabetes) Trial.

In simple terms

This study tried to see if a special workout machine helps older people with diabetes control their blood sugar. It randomly gave some people the workout and others none, which is a good way to test cause and effect. But we don’t know if the doctors or patients knew who got the workout, so we can’t be 100% sure the workout caused the changes.

Based on the study abstract and findings.

  1. 1For people with very poor blood sugar control, this training helped — but not for everyone.
  2. 2Cholesterol improved regardless.
  3. 3Overall, blood sugar didn't improve.
  4. 4But in those with very high blood sugar at start (HbA1c >7.5%), it dropped.
