Studies investigating aerobic exercise: Studies
measuring the effect of aerobic exercise on glycemic
control presented variable results[60-63]. Only one study
recognised a significant improvement in HbA1c after
12-wk exercise (girls swimming twice a week for 45
min a week)[61]. In a study investigating the impact
of the frequency of the supervised aerobic training on glycemic control, exercise three times a week (one
hour) for three months had no significant impact on
glycemic control, but exercise four times a week (one
hour) for 6 mo resulted in a significant improvement[60].
Neither guided or self-directed home-based aerobic
exercise program nor supervised Pilates exercise had a
significant effect on glycosylated haemoglobin after a
12-wk session
