title: 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-six women with type-2 diabetes were stratified into short- (3 ± 2 years; n = 12) or long-standing (10 ± 3 years; n = 14) disease groups. Patients participated in a high daily or high weekly frequency elastic band resistance training program that consisted of 2 daily sessions, 5 d·wk for 12 weeks. Glucose control, body composition, and physical function were evaluated pre- and posttraining. No significant diabetes duration × 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 (hemoglobin A1c, -13 to 18%; fasting glucose, -23 to 31%; postprandial glucose, -36 to 40%; insulin, -34 to 40%; C-peptide, -38 to 51%; p ≤ 0.05). Anthropometrics and body composition were also favorably modified in both the groups after training (weight, -5 to 9%; body mass index, -6 to 9%; waist-to-hip ratio, -3 to 5%; percent fat, -14 to 20%; p ≤ 0.05). Likewise, indices of physical function improved in both the 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.
