Aim: The present study was done to see the Influence of moderate and severe intensity resistance exercises on some cardiovascular risk factors.
Methods: 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.
Results: 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).
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.
