Background: Resistance exercises with high loads of HLRT cause physiological changes in body systems, including the immune system. On the other hand, little research has been done on the effect of high-intensity bodybuilding exercises on women's immune systems. The present study investigated the effect of resistance activity in a single bout with two different intensities and recovery on TNF-α and interleukin-6 gene expression, hs-CRP, and systemic immune-inflammatory marker SII on female bodybuilders.
Methods: In this semi-experimental study, 12 healthy female athletes (aged 30 ± 5) volunteered. The samples performed weekly resistance training at 70% and 85% of 1RM in two recovery times of one and two minutes. Thirty-six hours after training, sampling was done following a ten-hour fasting period. The samples were centrifuged at 3000 rpm and kept at -20 ℃. Ultimately, all levels of TNF-α and interleukin-6, hs-CRP, and systemic immune-inflammatory markers SII were checked in the medical laboratory. A consent form was obtained from the participants.
Findings: The results of resistance training using the HLRT method compared to moderate-intensity resistance training showed an increase in training intensity of up to 85% 1RM and a one-minute recovery. There was a significant decrease in the level of interleukin-6, TNF-α (P < 0.001), and hs-CRP (P < 0.025) and a significant increase in the level of SII systemic immune-inflammatory markers (P < 0.001).
Conclusion: It seems that increasing the intensity of resistance training - with increasing load - HLRT does not hurt the immune system, and it reduces pro-inflammatory factors interleukin-6, TNF-α and hs-CRP, as well as increases SII in female bodybuilders.
