Abstract:

Aims: Matrix Metalloproteinases (MMPs) are a group of in charge of extracellular matrix decomposition. The present research aimed at investigating the effects of ۸ weeks of aerobic training on MMP plasma levels in lifeguards. Materials & Methods: This study was a quasi-experimental one with ۱۹ volunteer participants who were randomly assigned to either the control group (n=۸) or the experimental group (n=۱۱). The latter did aerobic exercises in water for ۸ weeks at ۶۵ to ۷۵% of their reserved heart rate. Fasting blood samples (۱۰cc) were collected from the brachial vein before and after the training protocol. was determined by applying ELIZA (Enzyme-Linked Immunosorbent Assay) method and the data were analyzed using SPSS ۱۶ software. The significance level was set at p<۰.۰۵. Findings: Results showed a significant increase in MMP-۲ level in the experimental group as compared to the control group. Conclusion: Increasing MMP levels due to ۸ weeks of aerobic exercise in water may play an important role in physiological functions and tissue homeostasis. It may indicate remodeling of muscle fibers and connective tissue.
