Metabolic transition in trained people in progressive test with resistance training and running

INTRODUCTION: The specificity of cardiorespiratory and metabolic adaptations of aerobic and strength training evoke different responses during cardiopulmonary exercise testing (CPET). Objective: To describe the cardiorespiratory behavior during metabolic transition (MT) of CPET, runners and bodybuilders compared to a control group. METHODS: Men aged 21-55 years were grouped as follows: runners group (RG, n=30), strength group (SG, n=23) and control group (CG, n=38). The subjects underwent anthropometric and CPET assessment with analysis of ventilatory anaerobic threshold (VAT) and the respiratory compensation point (RCP). We calculated the running economy by the relationship between VO2 and test speed (ECINCLINA). RESULTS: In metabolic transition phase, the running speed (km/h) was higher in the RG group (4.2±1.6) vs. CG (2.7±1.6) and SG (2.8±1.0); P
