Background Although both strength training (ST) and endurance training (ET) seem to be beneficial in type 2 diabetes mellitus (T2D), little is known about post-exercise glucose profiles. The objective of the study was to report changes in blood glucose (BG) values after a 4-month ET and ST programme now that a device for continuous glucose monitoring has become available.
Materials and methods Fifteen participants, comprising four men age 56·5 ± 0·9 years and 11 women age 57·4 ± 0·9 years with T2D, were monitored with the MiniMed (Northridge, CA, USA) continuous glucose monitoring system (CGMS) for 48 h before and after 4 months of ET or ST. The ST consisted of three sets at the beginning, increasing to six sets per week at the end of the training period, including all major muscle groups and ET performed with an intensity of maximal oxygen uptake of 60% and a volume beginning at 15 min and advancing to a maximum of 30 min three times a week.
Results A total of 17 549 single BG measurements pretraining (619·7 ± 39·8) and post-training (550·3 ± 30·1) were recorded, correlating to an average of 585 ± 25·3 potential measurements per participant at the beginning and at the end of the study. The change in BG-value between the beginning (132 mg dL−1) and the end (118 mg dL−1) for all participants was significant (P = 0·028). The improvement in BG-value for the ST programme was significant (P = 0·02) but for the ET no significant change was measured (P = 0·48). Glycaemic control improved in the ST group and the mean BG was reduced by 15·6% (Cl 3–25%).
Conclusion In conclusion, the CGMS may be a useful tool in monitoring improvements in glycaemic control after different exercise programmes. Additionally, the CGMS may help to identify asymptomatic hypoglycaemia or hyperglycaemia after training programmes.
