Galectin-3 is a member of the galectin family and galectin-3 used as a diagnostic or prognostic biomarker for certain types of heart disease, kidney disease and cancer. Intensive exercise increases the levels of this protein, but the effect of regular exercise to ameliorate galectin-3 responses to high-intensity exercise is not well known. The present study was done to examine the effect of regular resistance training on galectin-3 responses to a bout of heavy resistance training. Eleven young men (age: 26.6±1.5 years old) volunteered to participate in this quasi study. One reparation maximum (1-RM) was measured and the subjects 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 squat) of 8 repetitions with 3 sets at 80% of 1RM. Thereafter, all the subjects performed 3 sets of the same resistance training with 65-80% 1RM, 3 days a week for 8 weeks. 48h after the last session of training, a bout of heavy resistance exercise was done again. Blood samples were taken at baseline and immediately after the heavy resistance exercise trials. The results demonstrated that galectin-3 increases after the first bout of heavy resistance exercise (P<0.05), while galectin-3 concentration reduce after the 8 weeks of regular resistance training and it remain low after the second bout of heavy resistance exercise. Generally, we can conclude that regular resistance exercise is effective to ameliorate galectin-3 responses to a bout of heavy resistance training in young men.

Abstract
Aim: Clinical studies indicated that types of exercise might have different effects on cardiac health and function. The effect of strength and endurance exercises-induced cardiac release proteins on its health is no clear. Thus, the aim of the present study was to compare the Galectin-3 and NT-ProBNP ...

Aim: Clinical studies indicated that types of exercise might have different effects on cardiac health and function. The effect of strength and endurance exercises-induced cardiac release proteins on its health is no clear. Thus, the aim of the present study was to compare the Galectin-3 and NT-ProBNP levels in strength and endurance elite athletes.
Method: Fifteen elite body builders (mean ± SD age of 23.0 ± 1.4 years and BMI: 24.1 ± 1.4 kg/m2) and fifteen elite endurance runners (mean ± SD age of 21.4 ± 3.0 years and BMI: 21.7 ± 2.0 kg/m2) with at least 3 years of tournament playing were participated in this study as the subject. Anthropometric and body composition parameters were measured. Fasting blood sample was taken for galectin-3 and NT-ProBNP measurements. Data were analyzed by Mann-Whitney U test. Data analyses were performed using SPSS software for windows (version 17) and the level of significance in all statistical analyses was set at P≤0.05.
Results: The results indicated that galectin-3 and NT-ProBNP were higher in the strength elite athletes than the endurance elite athletes were (P<0.05).
Conclusion: In conclusion, it seems that type of exercise is effective on blood galectin-3 and NT-ProBNP concentrations.
