| Abstrakt: | Background: In recent years, several studies have shown the association between exercise and decreased risk of mortality in patients with breast cancer. However, the effects of combined resistance and endurance training on salivary Interleukin-12 (IL-12), tumor necrosis factor (TNF-α), Cortisol, and Testosterone levels in patients with breast cancer have not been investigated. Objectives: This study aimed at determining the effect of 8 weeks of combined resistance and endurance training on salivary IL-12, TNF-α, Cortisol, and Testosterone levels in women with breast cancer. Methods: Forty-two postmenopausal women with breast cancer were randomly selected and divided into training (intervention) and control groups. The training group performed resistance training with 2 to 3 sets, 10 to 18 repetitions, 50 to 70% 1 repetition maximum (1RM), and aerobic exercise with 50 to 70% maximum heart rate (maxHR) (12-14 degrees borg scale) for 20 to 40 minutes for 8 weeks. The salivary IL-12, TNF-α, cortisol, and testosterone levels were measured, using the enzyme-linked immunosorbent assay (ELISA) method. Two-way analysis of variance repeated measure was also used to analyze variance with the confidence interval of 95%. Results: In the training group, there was a significant decrease in salivary TNF-α levels, cortisol, TNF-α/IL-12 ratio, and variables of weight, fat percentage, body mass index (BMI), and waist circumference (P < 0.05). Also, the results showed a significant increase in salivary testosterone and testosterone/cortisol ratio in the intervention group (P < 0.05). However, no significant changes were observed in the interaction between-group and time in IL-12 and waist--hip ratio (WHR) values (P > 0.05). Conclusions: The results indicate that resistance and endurance training could be used as a useful method to improve salivary pro-inflammatory factors and hormonal levels in patients with breast cancer. Medical oncologists can underline a resistance and endurance training program for patients with breast cancer under their care. [ABSTRACT FROM AUTHOR] |
