Weight-training can help prevent type 2 diabetes in men, according to a new study published in the Archives of Internal Medicine Journal.
Researchers found regular weight-training reduced the risk by up to a third, in the study of more than 32,000 men.
It is already well-known that regular exercise can prevent the disease. But the report is considered important as weight-training could provide an alternative to aerobic exercise for people who have mobility issues.
Researchers from Harvard School of Public Health in the US and the University of Southern Denmark followed the men over an 18-year period, during which time nearly 2,300 developed the condition.
They found 30 minutes of weight-training a day, five times a week could reduce the risk of diabetes by 34%.
But they also reported that even less regular exercise – up to an hour a week – had an impact, cutting the risk by 12%.
Nonetheless, aerobic exercise was still found to be slightly better with regular activity halving the risk.
The two combined had the greatest effect, reducing it by up to 59%, the study found.
Lead author Anders Grontved said: “Many people have difficulty engaging in or adhering to aerobic exericse.
“These new results suggest that weight-training, to a large extent, can serve as an alternative.”
