The Study
Comparative effects of different intensities of aerobic and resistance exercise on glycemic control and cardiorespiratory fitness in middle-aged older patients with type 2 diabetes: a network meta-analysis
This study didn't test exercise itself—it looked at many other studies where people were randomly assigned to different exercise routines. It found that some types of exercise, like lifting weights or walking fast, seem to help lower blood sugar and improve fitness in older adults with diabetes. But it can't say for sure that one type is the absolute best, because the evidence isn't perfect for every outcome.

Key takeaways
Summary
Based on the study abstract and findings.
- 1A 0.62% drop in HbA1c is clinically meaningful—like going from poorly controlled to better-controlled diabetes; a 29 mg/dL drop in fasting glucose is a big improvement for daily energy and health; a 3.75 mL/kg/min boost in fitness makes daily activities much easier.
- 2High-intensity weight training lowered HbA1c by 0.62%, moderate weight training lowered fasting blood sugar by 29 mg/dL, and combining high-intensity cardio and weight training boosted fitness by 3.75 mL/kg/min.

Resistance training improves muscle ability to absorb glucose from the blood, resulting in lower blood glucose levels after eating carbohydrates.
In middle-aged and older adults with type 2 diabetes, performing high-intensity resistance training three times per week for 3 to 12 months lowers HbA1c by an average of 0.62 percentage points, which is a clinically meaningful improvement and the most effective form of exercise for long-term blood sugar control in this group.
In middle-aged and older adults with type 2 diabetes, doing moderate-intensity resistance training three times per week for 3 to 6 months lowers fasting blood glucose by an average of 29.1 mg/dL, and among all forms of exercise, only this type has been shown with moderate-certainty evidence to produce this specific change.
In middle-aged and older adults with type 2 diabetes, doing three weekly sessions of high-intensity cardio and strength training raises peak oxygen uptake by an average of 3.75 mL/kg/min more than any other exercise program tested.
In middle-aged and older adults with type 2 diabetes, performing high-intensity resistance training three times per week for 3 to 12 months lowers systolic blood pressure by an average of 3.68 mmHg, and among exercise types, only this form shows a statistically significant reduction based on low-certainty evidence.
Middle-aged and older adults with type 2 diabetes who do high-intensity aerobic exercise three times a week for 8 to 12 weeks experience an average increase of 3.14 mL/kg/min in their peak oxygen uptake.
