While facility-based resistance training (RT) improves glycemic control for individuals with type 2 diabetes (T2D), studies in home-based settings have been less successful, perhaps because the exercise equipment provided could not provide adequate stimulus for muscle hypertrophy. It has not been established whether home-based resistance training is efficacious and feasible for this population. The purpose of this study was to investigate whether a home-based, RT program could improve strength, clinical markers, and quality of life (QoL) factors in obese T2D adults. 48 individuals were randomly assigned to 16 weeks of either treatment (n=27) or control (n=21). Individuals in the treatment condition received a multi-gym apparatus and free weights, along with supervised home instruction from a qualified trainer. This supervision gradually decreased from 3 times per week to 2 times per month; overall participants were supervised for 18 of 48 sessions. Intention-to-treat ANCOVAs, adjusted for baseline scores, were completed on the pre- and post-study measures at 16 weeks (loss to follow-up was 15%). Significant improvements in strength (24-40% mean increases in bench press, leg press, and upright row), HDL-C, fasting insulin, and dimensions of QoL were observed in the intervention group in comparison to the controls at the p < .05 significance level. Baseline mean Ale was 6.9 and did not change. There were no significant differences in blood pressure, anthropometrics, body composition by DEXA, LDL-C, or c-reactive protein between the two groups. Overall, home-based, resistance training with high quality equipment and supervision is feasible in obese people with T2D and can improve strength, HDL-cholesterol, and quality of life.
