Resumo

Introduction: Obesity is one of the most important link factors to coronary artery disease development mainly due to the pro-inflammatory and pro-thrombotic states favoring atherosclerosis progression. The LLLT acts in the cellular metabolism and it is highly effective to improve inflammation. The same occur in response to different kinds of exercise. However, we have not known the associate effects using LLLT therapies with aerobic plus resistance training as strategy specifically with target at human obesity control and its comorbidities. Objective: Investigate the effects of the LLLT associated with aerobic plus resistance training on cardiometabolic risk factors in obese women. Methodology: Women aged 20-40 years (BMI >= 30 kg/m(2)), were divided into 2 groups: Phototherapy (PHOTO) and Placebo. They were trained aerobic plus resistance exercises (in a concurrent mode), 1 h, 3 times/week during 16 weeks. Phototherapy was applied after each exercise session for 16 min, with infrared-laser, wavelength 808 nm, continuous output, power 100 mW, and energy delivery 50 J. The body composition was measured with bioimpedance. Inflammatory mark concentrations were measured using a commercially available multiplex. Results: LLLT associated with aerobic plus resistance training was effective in decrease neck (P = 0.0003) and waist circumferences (P = 0.02); percentual of fat (P -= 0.04); visceral fat area (P = 0.02); HOMA-IR (P = 0.0009); Leptin (P = 0.03) and ICAM (P = 0.03). Also, the reduction in leptin (P = 0.008) and ICAM-1 (0,05) was much more expressive in the phototherapy group in comparison to placebo group when analyzed by delta values. Conclusion: LLLT associated with concurrent exercise (aerobic plus resistance training) potentiates the exercise effects of decreasing the cardiometabolic risk factors in obese woman. These results suggest the LLLT associated with exercises as a new therapeutic tool in the control of obesity and its comorbidities for obese people, targeting to optimize the strategies to control the cardiometabolic risk factors in'these populations.
