Introduction: Resistance training has many beneficial effects on health and performance for athletes and non-athletes. This study aimed to explore the effects of a 12-week resistance exercise program on the biochemical parameters among healthy young male adults. Methods: Male adults aged 19-27 years were included in resistance exercise program. The participants exercised on both weight machines and free weights, 3 times per week for 1 hour per session. Blood samples were collected and tested at 2 h pre-exercise and 1 h post-exercise at the 1, 6 and 12 weeks. Analyses included hematology, blood cell counts, serum chemistry, liver function/muscle damage, metabolites and electrolytes. Results: No significant change in hematology was between pre- and post-exercises were observed. The numbers of white blood cells (6.23±1.49×103/uL versus 7.24±1.85×103/uL) and neutrophils (55.41±7.72% versus 63.85±10.03%) significantly increased immediately after resistance exercise (p < .05), in contrast to the percentages of lymphocytes and eosinophils that showed significant decreases after exercise (p < .05). Elevated levels of markers (erythrocyte sedimentation rate and neutrophils/lymphocytes ratio) indicated there were transient and acute inflammatory responses after each resistance training session. Although no evident exercise-induced muscle damage, significant changes in electrolytes were more commonly detected at each of post exercises. The exercises of resistance training predicted significant changes in some of the measurements, but only at the 1st and/or 2nd months post exercises. Conclusion: The results suggest that the participants had physiological adaptations 2 months after the resistance training, in response to exercise stress. Future studies are necessary to demonstrate the dose-effect relationships between exercise and outcomes, and to strike the optimal and applicable exercise programs. |
