Abstract
Aims: To investigate the effects of exercise in combination with a glucagon-like peptide-1 receptor agonist (GLP-1RA), liraglutide, or placebo for the treatment of type 2 diabetes. Methods: Thirty-three overweight, dysregulated and sedentary patients with type 2 diabetes were randomly allocated to 16 weeks of either exercise and liraglutide or exercise and placebo. Both groups had three supervised 60-minute training sessions per week including spinning and resistance training. Results: Glycated haemoglobin (HbA1c) levels dropped by a mean ± standard deviation of 2.0% ± 1.2% (from 8.2% ± 1.4%) in the exercise plus liraglutide group vs 0.3% ± 0.9% (from 8.0% ± 1.2%) in the exercise plus placebo group (P <.001), and body weight was reduced more with liraglutide (−3.4 ± 2.9 kg vs −1.6 ± 2.3 kg; P <.001). Compared with baseline, similar reductions were seen in body fat (exercise plus liraglutide: −2.5% ± 1.4% [P <.001]; exercise plus placebo: −2.2% ± 1.9% [P <.001]) and similar increases were observed in maximum oxygen uptake (exercise plus liraglutide: 0.5 ± 0.5 L O2 /min [P <.001]; exercise plus placebo: 0.4 ± 0.4 L O2 /min [P =.002]). Greater reductions in fasting plasma glucose (−3.4 ± 2.3 mM vs −0.3 ± 2.6 mM, P <.001) and systolic blood pressure (−5.4 ± 7.4 mm Hg vs −0.6 ± 11.1 mm Hg, P <.01) were seen with exercise plus liraglutide vs exercise plus placebo. The two groups experienced similar increases in quality of life during the intervention. Conclusions: In obese patients with type 2 diabetes, exercise combined with GLP-1RA treatment near-normalized HbA1c levels and caused a robust weight loss when compared with placebo. These results suggest that a combination of exercise and GLP-1RA treatment is effective in type 2 diabetes.
