Introduction: Galectins are a family of carbohydrate-binding proteins with an affinity for beta-galactosides. Galectin-3 is a member of the galectin family and numerous previous studies have indicated that galectin-3 may be used as a diagnostic or prognostic biomarker for certain types of heart disease, kidney disease and cancer. The aim of present study was to investigate the effect of a bout of heavy resistance training on galectin-3 in healthy young men. Material & Methods: Elevenhealthy young men (aged: 26.6 ± 1.5 years; ± SD) volunteered to participate in this study. One reparation maximum (1-RM) was measured and the subjects were performed a heavy resistance exercise trial consisted of eight exercises (chest press, triceps extension, latissimus pull down, shoulder press, arm curls, leg extension, leg curls, and curl-up) of 8 repetitions with 3 sets at 80% of 1RM. Blood samples were taken at baseline and immediately after the heavy resistance exercise trial. Results: The results showed that galectin-3 level was increased significantly in response to heavy resistance exercise trial (365.9±110.3 mg/dl vs. 390.6±117.7 mg/dl; P=0.012). No significant relationships were observed between galectin-3 levels after the intervention with cholesterol (P=0.16), triglycerides (P=0.29), LDL (P=0.34) or HDL (P=0.92). Conclusions: The results suggest a bout of heavy resistance training increases galectin-3 healthy young men.
