Balanced Fitness Plan Does Best
Want a fitness routine that lowers blood glucose longer? Try hitting the weight room. In a study, 12 people with type 1 diabetes spent 45 minutes on a treadmill, lifting weights, or resting. Researchers using continuous glucose monitors found that participants' glucose levels decreased more during aerobic exercise than while lifting weights. Over the next 24 hours, however, the treadmill users' blood glucose came back up while the weight lifters maintained a lower level longer. So, on average, lifting weights did a better job at keeping blood glucose down over the course of a day—muscle mass helps use and store glucose. Experts recommend both strength training and aerobic activities for blood glucose control.
