Effects of an aquatic-based exercise program to improve cardiometabolic profile, quality of life, and physical activity levels in men with type 2 diabetes mellitus

Background: The role of structured exercise in improving cardiometabolic profile and quality of life in patients with type 2 diabetes mellitus (2DM) has been widely demonstrated. Little is known about the effects of an aquatic-based exercise program in patients with 2DM. Objective: To evaluate the effects of a supervised aquatic-based exercise program on cardiometabolic profile, quality of life, and physical activity levels in patients with 2DM. Design and Setting: Observational study, community pre-post aquatic-based exercise program, primary care intervention. Patients: Eighteen men diagnosed with 2DM (52.2 ± 9.3 years). Methods: and Main Outcome Measurements: Cardiometabolic profile, quality of life, and physical activity levels were assessed before and after 12 weeks of an aquatic-based exercise program. Results: The results show a significant improvement of cardiometabolic assessments (maximum oxygen consumption: 24.1 versus 21.1 mL/kg/min, P <.05; blood pressure: 125.4/77 versus 130.7/82.5 mm Hg, P <.05; fasting blood glucose: 119.6 versus 132.5 mg/dL, P <.05; body mass index: 29.9 versus 31.1 kg/m2, P <.005; low-density lipoprotein cholesterol: 95.2 versus 104.9 mg/dL, P <.05; and diastolic function: E/E' 9.1 versus 10.1, P <.005) and an increase in quality of life and physical activity levels (Medical Outcome Study 36-item Short Form Health Survey mental component summary: 72.3 versus 67, P <.05; Problems Area About Diabetes: 20.1 versus 33.2, P <.005) and energy expenditure in general physical activity (physical activity: 3888.7 versus 1239.5 kcal/wk, P <.05). Conclusions: These findings demonstrate that an aquatic-based exercise program produces benefits for the cardiovascular system and metabolic profile and appears to be safe and effective in improving quality of life and increasing physical activity levels in patients with 2DM.
