Abstract

Background and Aim: Previous studies have shown that regular aerobic exercise improves fertility. However, there were conflicting results regarding the effect of Resistance training on fertility. The aim of this study was to investigate the effects of Resistance training (RT) with two different volumes on some semen parameters and serum levels of Sex hormones in male rats. Materials and Methods: Twenty-four male Wistar rats (157. 7± 7. 6 gr) were randomly divided into 3 groups; control, high volume RT, low volume RT (8 rats in each group). The Resistance training program included climbing the ladder for 8 weeks (3 days/week, every other day). Body weight, serum concentrations of testosterone (Ts), follicle stimulating hormone (FSH) and luteinizing hormone (LH) were measured as well as the number and total Sperm motility was calculated. Data were analyzed using one-way ANOVA and Bonferroni post hoc tests at the significant level of p<0. 05. Results: After 8 weeks of Resistance training serum levels of LH in high volume RT group were lower compared with control group (p=0. 03). Higher levels of FSH in low volume RT group was found compared with high volume RT group (p=0. 009). There were no significant differences between groups in serum levels of testosterone, body weight values, number and total Sperm motility (p>0. 05). Conclusion: According to these results, it seems that a disproportionate increase in Resistance training volume can lead to decrease the levels of some Sex hormones. Therefore, it may lead to disruption of the spermatogenesis.
