Abstract

Background Circulatory (CP) and ventilatory power (VP) have been used to improve the prognostic accuracy of cardiopulmonary exercise tests in cardiovascular disease, such as coronary artery disease. However, the effects of combined resistance and aerobic exercise program on VP and CP, especially in type 2 diabetes patients, have not been adequately investigated. Thus, this new parameter can be useful to prescribe exercise programs more assertive for this population. The present study aimed to assess the effect of 3 months of combined resistance and aerobic exercise training (CET) on CP and VP in patients with type 2 diabetes. Methods A randomized controlled trial was conducted involving 48 diabetic patients with an average age of 52.4 (+/- 8.01) years old. The subjects were randomized into two groups: sedentary (SG, n = 15) and the CET group (n = 19). Cardiopulmonary exercise testing (symptom-limited incremental) was performed on a cycle ergometer, and the following parameters were measured: relative VO2, V-E/VCO2 slope, linear relationship between oxygen uptake and minute ventilation, and VCO2. CET was performed with 30-min aerobic and 30-min resistance exercises three times a week for 12 weeks. Results Significant (p < .05) and clinical (d >= .80) differences were observed that favoured CET compared with SG for the following variables: heart rate, workload, VO2 relative peak, circulatory power peak, and VCO2 peak. Although no statistical difference was observed for ventilatory power, there was a clinical difference (p > .05 and d >= 0.80) that favoured CET. Conclusion Three months of combined exercise training improved VP and CP indices in patients with type 2 diabetes when compared with a sedentary group. (AU)
