Introduction: We designed this study, to investigate the effect of a single resistance exercise session on serum C-reactive protein (CRP) and cardiometabolic riskfactors in trained and untrained young healthy male students and to evaluate whether regular training may affect the response of these markers to exercise.

Method: According to training status 34 healthy male students divided to 19 trained and 15 untrained groups. Each group was then randomly divided to intervention and control groups. The final groups included experimental trained (ET), control trained (CT), experimental untrained (EU) and control untrained (CU). The experimental groups underwent exercise training that consisted of 120 min intensive resistance program at 70–80% of 1 RM. The blood samples were collected just before the start of training program and 4 h post exercise to evaluate CRP and other metabolic markers.

Results: ANOVA analysis showed the serum level of blood sugar, insulin, components of lipid profile and CRP were not significantly different between four groups at baseline. More over 4 h post exercise CRP concentration and other cardio vascular riskfactors did not differ between 4 groups. Additionally the paired t-test showed the serum level of CRP and metabolic risk factors was not changed in response to acute resistance exercise in any group.

Conclusion: Our results indicate that one session of acute resistance exercise had no effect on serum concentration of CRP and cardio metabolic risk factors in healthy male students, no matter they were trained or untrained.
