EFFECTS OF ELASTIC BAND RESISTANCE TRAINING ON GLUCOSE CONTROL, BODY COMPOSITION, AND PHYSICAL FUNCTION IN WOMEN WITH SHORT- VS. LONG-DURATION TYPE 2 DIABETES.
Abstract
This study examined whether the existing duration of type 2 diabetes influenced patient responses to progressive resistance training. Twenty-sixwomen with type 2 diabetes were stratified into short (3?2 y, n=12) or long-standing disease groups (10?3 y, n=14). Patients participated in a high daily/high weekly frequency elastic band resistance training program that consisted of two daily sessions, 5 days/week for 12 weeks. Glucose control,body composition, and physical function were evaluated pre- and post-training.
No significant diabetes duration x training interactions were detected for blood markers of glucose control (p>0.05); however, there were significant main effects of training driven by comparable improvements in both cohorts (HbA1c: -13-18%; fasting glucose: -23-31%; post-prandial glucose: -36-40%; insulin: -34-40%; C-peptide: -38-51%; p<0.05). Anthropometrics and body composition were also favorably modified in both groups after training (weight: -5-9%; BMI: -6-9%; waist-to-hip ratio: -3-5%; percent fat: -14-20%; p<0.05). Likewise, indices of physical function improved in both groups after training (bicep curl repetitions: +15-33%; sit and stand repetitions: +45-47%; p<0.05). A few exceptions were noted in which patients with long-standing disease demonstrated greater pre to post gains (p<0.05) in grip strength (+11-13%) and peak exercise time (+19%) and load (+21%) during graded exercise whereas those with shorter disease duration did not.
Overall, these data suggest that patients with a long history of diabetes respond positively to resistance training and in a manner comparable to their recently diagnosed counterparts. Therefore, current inactivity in patients with long-standing disease should not deter from beginning an exercise program.
