Effects of Different Exercises Training associated with Phototherapy on Cardiometabolic Risk in Obese Women

Abstract

In the past, exercise in obesity control, mostly weight loss programs are associated with aerobic training. However, aerobic plus resistance training (ART) can promote weight loss and positively affect some metabolic parameters. Recently, it has demonstrated the benefits to use the phototherapy associate to physical exercise practice in obese women. PURPOSE: Investigate the effects of different exercises training associated with phototherapy on cardiometabolic risk in obesity women. METHODS: It was involved 33 obese women with age of 20-40 years in a weight loss therapy during 4 months. Inclusion criteria were primary obesity, body mass index greater than 30 kg/m2 and less than 40 kg/m2. The voluntaries were assigned in two different groups: Aerobic Training (AT) and Aerobic plus Resistance Training (ART) groups. The interventions consisted on physical exercise training and application of phototherapy (830nm), immediately after the physical exercise. Metabolic parameters were evaluated. RESULTS: It were showed reduction in body mass (ART: 93±11 vs 89 ± 11, p 0.001; AT: 94±16 vs 89 ± 16 kg, p 0.001), body mass index (ART: 35±4 vs 31±4, p 0.001; AT: 35±4 vs 33±4 kg/m2, p 0.001), fat mass (ART: 40± 3 vs 37±4, p 0.001; AT: 47±3 vs 44±4%, p 0.001), visceral fat (ART: 153±19 vs 135±17, p 0.004 AT: 160±34 vs 150±36 cm3, p 0.003), total cholesterol (ART: 205±24 vs 180±22, p 0.002; AT: 183±43 vs 163±51 mg/dl, p 0.04), neck (ART: 38±3 vs 35±2, p 0.001; AT: 38±2 vs 37±2 cm, p 0.04) and waist (ART: 108±11 vs 105±10, p 0.002; AT: 99±8 vs 92±7cm, p 0.001) circumferences in both groups. Only ART group demonstrated increase in lean mass (60±3 vs 66±7%, p 0.001) and adiponectin (7.5±3.4 vs 10.17±4.1 ng/l, p 0.001). In addition, reduction in triglycerides (133±38 vs 108±42 mg/dl, p 0.01) was noted only in ART group. Two-way ANOVA with repeated measures was applied. CONCLUSIONS: It was showed that ART associated with phototherapy applied in obese women was more effective than AT to improve health status in obese woman, reducing the cardiometabolic risk in this population.
