A new study led by researchers at the University of Calgary and the University of Ottawa has found that a group of non-exercising diabetes type-2 sufferers enjoyed major gains in blood sugar control when they combined cardio and strength building exercise.
They were divided into four groups for the tests: one group did cardio exercise, one did strength building resistance exercise, one did a combination of both, and one did no exercise. As expected, all the exercising groups enjoyed benefits over the non-exercisers, but most significantly, the group that undertook a combination of both types of exercise doubled the benefits of the single activity exercisers.
Gains were measured in blood sugar control levels, and for the combination exercisers were translated into benefits by an approximate 15%-20% reduction in heart attack and stroke risk, and a 25%-40% lower risk of diabetes-related eye or kidney disease. Exercise also led to modest weight loss where none was expected (diet had been designed to maintain weight) and a reduction of belly fat.
