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.
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.
Analysis score
Maximum 90 for a randomized controlled trial.
Where the score came from
Older Chinese adults with type 2 diabetes did a special kind of strength training for 6 months to see if it helped their blood sugar.

Key takeaways
Summary
Based on the study abstract and findings.
- 1For people with very poor blood sugar control, this training helped — but not for everyone.
- 2Cholesterol improved regardless.
- 3Overall, blood sugar didn't improve.
- 4But in those with very high blood sugar at start (HbA1c >7.5%), it dropped.
- 5Their good cholesterol (HDL) went up, bad cholesterol (LDL) went down.

Claims (4)
Resistance training improves muscle ability to absorb glucose from the blood, resulting in lower blood glucose levels after eating carbohydrates.
In elderly Chinese patients with type 2 diabetes and poorly controlled blood sugar, six months of progressive resistance training using the bioDensity™ technique lowers HbA1c and fasting plasma glucose levels.
In elderly Chinese patients with type 2 diabetes, six months of progressive resistance training with bioDensity™ raises HDL cholesterol, lowers LDL cholesterol, and reduces total cholesterol, regardless of changes in HbA1c levels.
Six months of progressive resistance training using bioDensity™ equipment does not change HbA1c or fasting blood glucose levels in elderly Chinese individuals with type 2 diabetes.
