The present study was done to see the Influence of moderate and severe intensity resistance exercises on some cardiovascular risk factors. Thirty young healthy male were randomly divided in to two types of intervention [MI: moderate intensity (45-55% 1RM), HI: high intensity (80-90% 1RM)] and one Control (no intervention) groups. Subjects in MI and HI intervention groups underwent 3 supervised resistance-training sessions per week for six weeks. IL-1, IL-6, HS-CRP, fibrinogen, ApoB, ApoA, LDL, HDL, ApoB/ApoA ratio, Lipoprotein Lipase (LPL), TG, cholesterol, cholesterol/HDL ratio, body mass index (BMI), systolic pressure (Ps), diastolic pressure (Pd) and waist/hip ratio (WHR) before and after resistance training period were assessed. IL-1, IL-6, ApoB, ApoA, LPL, TG levels, ApoB/ApoA ratio, Ps, Pd, WHR, BMI and CPR did not change significantly in trained groups. In post test HS-CRP was significantly lower in trained groups in comparison to control group (p≤0.05). LDL, Cholesterol and cholesterol/ HDL ratio decreased significantly in trained groups (p≤0.05). In the HI group plasma level of fibrinogen were decreased while HDL level were increased (p≤0.05). In conclusion, resistance training for 6 weeks in young healthy males evoked beneficial effects regarding some inflammatory and cardiovascular risk markers. Higher-intensity resistance training was more effective in reducing plasma fibrinogen and increasing plasma HDL levels than moderate resistance training.
