The effects of resistance and endurance training on risk factors of vascular inflammation and atherogenesis in non-athlete men.

BACKGROUND

Studies show that different types of training have a significant role in reducing both new and traditional risk factors of cardiovascular diseases, and the new risk factors are more sensitive and accurate in predicting such diseases.

OBJECTIVE

The aim of this study was to determine the effects of resistance and endurance exercises on risk factors of vascular inflammation and atherogenesis in non-athlete men.

METHODS

Thirty-six non-athlete male students (mean age: 20.45 ± 1.20 years; mean body mass index: 23.66 ± 3.65 kg/m) were randomly assigned into either three groups: control group, resistance training (RT), and endurance training (ET). The training groups exercised for 3 days/week for 8 weeks. ET group performed treadmill-running at 65%-80% of maximum heart rate and with a 16-30 min duration; the task of RT group consisted of three repetition sets, 8-10 per set, at 60%-80% of one repetition maximum, with 2-min recesses. Blood samples were taken before and after the training program. Data were analyzed by Shapiro-Wilk test, one-way ANOVA, LSD test, and dependent -test (α ≤ 0.05).

RESULTS

The results indicated a significant reduction in total cholesterol levels in both RT and ET groups. Also high-density lipoprotein cholesterol significantly increased in both training groups. In addition, following 8 weeks, low-density lipoprotein cholesterol in ET group was significantly decreased, whereas these training methods have had no significant effects on the new cardiovascular biomarkers (hs-CRP, IL-6, and sICAM-1).

CONCLUSION

It seems that both ET and RT with improvement in lipid profiles could be effective in prevention and treatment of the cardiovascular disease.
