PURPOSE: This experiment compared the metabolic effects and effects on blood glucose levels of a single bout of free-weight or resistance band exercise in individuals with T2DM The metabolic costs of the two exercise modalities were also compared to young and older non-diabetic samples. METHODS: Young and older participants completed approximately 30-minutes of resistance exercise using free weight dumbbells or resistance bands, followed by a 30-minute monitoring period. The metabolic costs of exercise were recorded with gas analysis (ParvoMedics) and/or metabolic arm sensors (SenseWear Armband) and were compared to a brisk walking control condition. Older individuals with T2DM completed both resistance training modes compared to a sedentary control condition, with the additional measure of blood glucose taken a total of 5 times (Pre, 15-min, End, 15-min post, and 30-min post). RESULTS: T2DM and older participants achieved similar energy expenditure from resistance bands when compared to free weight training. Young participants however achieved a significantly greatly caloric expenditure from performing free weights compared to resistance bands and in aerobic exercise compared to resistance exercise. Both methods of resistance exercise resulted in significant decreases in blood glucose levels when compared to no exercise in participants with T2DM (P<0.005). CONCLUSION: Resistance band exercise appears to be an effective tool for aiding in the glycemic control of individuals with type 2 diabetes; however, more research is needed to examine the long-term health benefits from using a resistance band training program. Resistance band exercise may be a more valuable tool in older and diabetic individuals that are new to resistance training than younger individuals who may require higher intensity exercise.
