| Abstract |
Background: The purpose of this study was to investigate the inflammatory response, lipid peroxidation and muscle damage in men and women athletes subjected to an acute resistance exercise.\n Methods: Twenty college athletes (10 men and 10 women) performed a half-squat exercise consisting of five incremental intensities: 20%, 40%, 60%, 80% and 100% of the one-repetition maximum. Blood samples were collected at rest, 15 min and 24 h post-test. The concentration of lipid peroxidation markers and the activities of a skeletal muscle damage marker and a cardiac muscle damage marker were determined in serum. Serum alpha-actin was measured as a marker of sarcomere damage. Serum levels of interleukin-6, interleukin-10, and tumor necrosis factor alpha were determined to assess the inflammatory response.\n Results: Interleukin-6 levels were higher at 24 h post-test than at rest and 15 min post-test in men (p < 0.05). Moreover, men showed significantly higher hydroperoxide levels in response to resistance exercise at 24 h post-test than at 15 min post-test (p < 0.05). No differences were found in muscle damage parameters regardless of sex or the time point of the test. No differences regarding the studied variables were found when comparing among different time points in women.\n Conclusion: Our results show a larger influence of half-squat exercises on the release of IL6 and on lipid peroxidation in men than in women at equivalent workloads. |
