MONDAY, Aug. 6 (HealthDay News) -- People with diabetes who boost their level of physical activity can reduce their risk of premature death, according to a new study.
And a separate study found that weight training alone may reduce the risk of developing diabetes in the first place.
The first study, which involved nearly 6,000 people with diabetes, found that those who were moderately physically active had the lowest risk of death.
Leisure-time physical activity -- such as biking, gardening and housework as well as walking -- was also associated with lower risk of death, found researcher Diewertje Sluik of the German Institute of Human Nutrition Potsdam-Rehbrucke, and colleagues.
In the other study, which included more than 32,000 men, researchers found weight training alone -- without aerobics -- can help prevent type 2 diabetes, possibly by increasing muscle mass and improving insulin sensitivity.
However, a combination of weight training and aerobic exercise provided the most preventive benefit.
Both studies were published online Aug. 6 in the journal Archives of Internal Medicine.
"Until now, previous studies have reported that aerobic exercise is of major importance for type 2 diabetes prevention," Anders Grontved, lead author of the weight-training study, said in a Harvard news release.
"But many people have difficulty engaging in or adhering to aerobic exercise. These new results suggest that weight training, to a large extent, can serve as an alternative to aerobic exercise for type 2 diabetes prevention," added Grontved, a visiting researcher at the Harvard School of Public Health and a doctoral student in exercise epidemiology at the University of Southern Denmark.
Using information on participants' weekly weight training and aerobic exercise habits from 1990 to 2008, the researchers found that men who weight train on a regular basis could reduce their risk for ty
