Researchers examined 14 controlled trials that compared participants at high risk of diabetes who underwent a resistance training intervention with those who did not. The studies showed training with resistance bands and weights helps control blood sugar and blood lipid levels – two of the most prominent risk factors for type 2 diabetes – in those more likely to get the disease.
Looking at the data, the researchers found the most significant improvements in outcomes for patients at risk for type 2 diabetes used specific training parameters – namely the use of free weights or resistance bands at intensities above 60% one-repetition maximum, with 10-15 repetitions at a time.
How does resistance training affect diabetes risk?
Resistance training seemed to be especially effective for lowering blood sugar, lipids, and body fat when done for at least 12 weeks.
According to the study authors, other benefits of resistance training include improved athletic performance, higher bone density, improved mood, flexibility, and improved muscle strength.
This isn’t the first time the connection between strength training and diabetes has been made. Research from the journal Mayo Clinic Proceedings showed that having even a moderate amount of muscle strength can lower the risk of developing type 2 diabetes by 32%.
Some researchers have suggested this type of training can help those who already have diabetes too. A research review in the journal Nutrition & Metabolism noted that resistance training is so effective for glycemic control and cholesterol metabolism in people with type 2 diabetes that they should incorporate the exercise into their treatment plan.
These findings align with the American Diabetes Association guidelines, which recommend that adults with type 2 diabetes combine a mixture of cardio and strength workouts.
