Abstract

Purposes: Irisin is a myokine that appears to convert white adipose tissue into brown adipose tissue. The current research aims to examine the effect of continuous training in water and high-intensity interval training (HIIT) on the amount of blood irisin of boxers.

Methods: In this study, 30 male boxers with at least two years of continuous training experience with an average age (26.51±3.15) and body mass index (25.86±5.38) were selected from active boxing athletes and randomly divided into two groups of continuous training and HIIT training and each group did their exercises for eight weeks and three sessions a weekBlood samples were taken before and after eight weeks of training, and the amount of serum irisin was measured using the ELISA method. Between groups, changes were evaluated using Mixed Anova and Bonferroni's post hoc test at a significance level of p˂0.05.

Results: Irisin serum level increased significantly in the continuous (P=0.015) and high interval training group (P=0.006) compared to the control group, although no significant difference was observed between the two training groups (P=0.955).

Conclusion: The current research shows that doing continuous sports activities and HIIT can lead to an increase in irisin levels and, thus a decrease in body fat percentage. However, none of the training programs was superior to the other.
