Can low-level laser therapy (LLLT) associated with an aerobic plus resistance training change the cardiometabolic risk in obese women? A placebo-controlled clinical trial
Abstract

•LLLT associated with aerobic plus resistance training on cardiometabolic risk factors in obese women•LLLT potentiate the exercise effects on cardiometabolic risk factors in obese women.•LLLT plus physical exercise was effective in decrease visceral fat and HOMA-IR.•LLLT plus physical exercise was effective in decrease leptin and ICAM.•LLLT as new therapeutic tool to the control of obesity and its comorbidities

IntroductionObesity 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.ObjectiveInvestigate the effects of the LLLT associated with aerobic plus resistance training on cardiometabolic risk factors in obese women.MethodologyWomen aged 20–40 years (BMI ≥ 30 kg/m2), 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.ResultsLLLT 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.ConclusionLLLT 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.
