The Effect of a Detraining Period after Two Type Concurrent Training on the Exercise ‎Performance and HbA1c in Women with Type II Diabetes

The purpose of this study was to investigate the effect of a period of detraining following two types of concurrent training on glycosylated hemoglobin and exercise performance in women with type 2 diabetes.

Twenty-three women with type II diabetes mellitus in Shiraz, randomly were divided into three groups: control group that performed one day endurance training and one day resistance training (Different Day), and a group that performed endurance and resistance exercises in one day (Same Day). Before and after 8 weeks of concurrent training and after four weeks of detraining, glycosylated hemoglobin (Hb A1c) measured after 12 hours of fasting. Maximum oxygen consumption (VO2max) and Time to Exhaustion (TTE) was also calculated through the implementation of the Balkan test on the treadmill.

Two months of concurrent training in both groups of training significantly decreased Hb A1c, a significantly increased in VO2max and TTE in women with type II diabetes (p≤0.05). One month after the concurrent training in SD group resulted in a significant decrease in VO2max and TTE (p ≥0.05), but this decrease was not statistically significant in the DD group. Increase in Hb A1c after detraining was not statistically significant in both training groups (p ≥0.05).

The findings indicate that concurrent training improves glycemic control and increases exercise performance (VO2max and TTE) in women with type II diabetes, but doing DD concurrent training results to keep longer outcomes of training in the detraining periods.
