Recent studies have suggested that strength training is just as effective as aerobic exercise for improving glucose metabolism. It was shown that four months of strength training increased glucose uptake by an average of 23%. These results are similar to those seen in aerobic exercise programs.
One interesting aspect of the strength training studies was that the improvements made in glucose metabolism were independent of changes in either body fat or cardiovascular fitness levels.
Both strength training and aerobic exercise have shown similar beneficial effects on glucose metabolism. The performance of both forms of exercise should not be overlooked when implementing exercise programs to help control or reduce the risk of diabetes.
