ACUTE EFFECTS OF STRENGTH TRAINING WITH DIFFERENT INTENSITIES ON INFLAMMATORY MARKERS OF GRADE III OBESE WOMEN

Objective: To compare the acute effects of a high-intensity (AI) resistance training protocol with a moderate-intensity (MI) resistance training protocol on inflammatory markers in grade III obese women. Methods: This is a crossover controlled clinical trial carried out with 9 obese grade III women (BMI=48.29±5.06 kg/m²; age=35.22±10.93 years), where blood samples were collected in the pre, 15 minutes and 24 hours after two different training protocols, high and moderate intensity, being analyzed the plasma concentrations of the cytokines IL-2, IL-4, IL-6, IL-10, TNF-α and IFN- γ. For data analysis, the Friedman and Mann-Whitney tests were used. Participants performed the AI protocol and one week later the MI protocol. The training consisted of 4 exercises with the total volume equalized, with intensities 75 and 85% of 1RM for the MI and AI protocols, respectively. Results: There were no significant differences between the three temporal measures in the AI group [IL-02 (p=0.459); IL-04 (p=0.368); IL-06 (p=0.368); IL-10 (p=0.895); TNF-α (p=0.895) and IFN-γ (p=0.895)] or MI [IL-02 (p=0.459); IL-04 (p=0.368); IL-06 (p=0.459); IL-10 (p=0.368); TNF-α (p=0.641) and IFN-γ (p=0.121)]. In the analysis between groups, the IL-04 value was significantly higher in the AI group at the PRE moment (p=0.008), with no other significant difference for any of the variables and moments analyzed. Conclusion: Moderate and high intensity strength training protocols did not cause acute changes in the inflammatory profile of grade III obese women, and can be applied to this audience without harming low-grade chronic inflammation.
