CIRCUIT TRAINING REDUCES CARDIOMETABOLIC RISK FACTORS IN WOMEN
REVISTA BRASILEIRA DE MEDICINA DO ESPORTE(2023)
摘要
Introduction: Combined training is more effective than an isolated modality in reducing cardiometabolic risk indicators. Objective: To evaluate the effect of circuit training volume on anthropometric and biochemical risk indicators for cardiometabolic diseases in overweight women. Methods: Thirty-two participants underwent 24 weeks of circuit training with free weights combined with aerobic exercise. The training volume during the 24 weeks was used to distribute the women into moderate-volume physical activity (MVA), low-volume physical activity (LVA) and control (CON) groups. Anthropometric indices (body mass, body mass index (BMI), waist circumference (WC), waist-hip ratio (WHR)), blood glucose, insulin, insulin resistance (HOMA-IR), total cholesterol ( TC), triglycerides, HDL-c, and LDL-c were evaluated at the beginning of the program and after 12 and 24 weeks. Results: There was no interaction between training volume and time for any of the variables studied, but the intervention time influenced body mass (p=0.013) and BMI (p=0.012), and there was a tendency for participation time to reduce body mass (p=0.063) and BMI (p=0.062) after six months of intervention. The volume of the physical activity affected HDL-c (p=0.037), being significant (p=0.030) in the comparison between the MVA and CON groups. Additionally, there was a downward trend in HDL- c after six months of intervention (p=0.073), with a smaller reduction observed in the MVA group, indicating a protective role of moderate physical activity in the reduction of this lipid fraction. The association between physical activity volume and participation time resulted in a clinical improvement in total cholesterol (chi 2 = 5.453, p = 0.02), with a higher probability of reaching clinically adequate values in the MVA group (OR = 0.126; 95%CI 0.019 - 0.827). Conclusion: Training volume improved cardiometabolic risk factors in overweight women.
