Efeito do treinamento concorrente nos componentes da síndrome metabólica de homens de meia-idade

INTRODUCTION: The practice of regular physical exercise is considered critical to prevention and treatment of metabolic syndrome, but little is known about the ideal form of training. OBJECTIVE: To investigate the effect of 16 weeks of concurrent training (CT) with weekly frequency and duration of the session similar to strength training (ST) and endurance training (ET) isolates, in the components of metabolic syndrome (MS) of middle-age men. METHODS: Forty-two clinically healthy men were selected and divided into four groups: ET (n = 13), ST (n = 9), CT (n = 10) and control group (CG, n = 10). The training was composed of two steps (E1 and E2) with a duration of eight weeks each, and frequency of three sessions/week (ST: ten exercises with 3 x 8-10 RM; AT: 60 min. Walking or running at 55 -85% VO2peak, CT: six exercises with 3 x RM 8.10, followed by 30 min. walking or running at 55-85% VO2peak). We evaluated waist circumference (WC), lipid profile, glucose, blood pressure (BP), maximum force and VO2peak. RESULTS: The WC reduced to the AT (-1.70%, p = 0.023) and CT (-1.66%, p = 0.018) and LDL to the ST (-25.03%, P = 0.047) and CT (29.74%, p = 0.011). The CT promoted the reduction in systolic BP (-7.83%, P = 0.029). The maximum force and peak VO2 increased for the three training groups (p > 0.05). CONCLUSION: The performance of CT weekly frequency and duration of sessions similar to the ET and ST alone is more effective for the improvement of MS components.
