The aim of this study was to investigate the effect of 8 weeks of resistance training on changes of C reactive protein (CRP) and cystatin C in male volleyball players. For this purpose, 20 volleyball players voluntarily participated in the study and were divided randomly into progressive resistance training (PRT, n=10) and control (Con, n=10) groups. PRT was conducted for 8 weeks, 3 sessions per week with the intensity of 70% maximal repetition (1RM) and reached 90% 1RM by the 8th week. Blood samples were collected before and after PRT to analyze CRP and cystatin C in the plasma. The results showed that in the interaction of time× group, there was a significant difference in cystatin C (P=0.047). However, the effect of time and the effect of time x group were not significant in CRP (P>0.05). It can be concluded that 8 weeks of progressive resistance training reduced cystatin C as a new inflammatory index. However, this protocol had no effects on basal CRP concentration. %U https://jsb.ut.ac.ir/article_60981_f2071fa254a80549b46d096ce0d359de.pdf
