This study was conducted with purpose of examination of the relationship between physical activity level and risk factors for coronary heart disease (CHD) for young sons. 30 male students with a mean age of 21.4 ± 1.14 years, height 176 ± 6.23 cm, weight 79.66 ± 5.39 kg and BMI 23.6 ± 2.53 kilo grams per square meter as cluster and random sampling were selected as subjects. Subjects completed questionnaires related to health, consent forms and questionnaires of physical activity level(Beack).Measurements in this study were: determination of body weight, height, body mass index (BMI), the estimation of percent of the body fat and determination of risk factors for CHD include: Cholesterol (TC), triglycerides (TG), low density lipoprotein (LDL), high density lipoprotein (HDL), systolic blood pressure (SBP) and diastolic blood pressure (DBP).For data analysis, appropriate descriptive and inferential statistical methods such as the KOLMOGOROV- Smirnov, T student and Pearson correlation at the significant level of 0.05 are used. The results showed that the level of physical activity has significant negative relationship with blood cholesterol level and LDL. While were not seen a significant relationship between the physical activity level with HDL and TG. On the other hand, the results of this study showed that there is significant negative relationship between the level of physical activity with body fat mass, body fat percentage and body mass index (BMI). The results of this study showed that between systolic and diastolic blood pressure, there is no significant relationship with the level of physical activity. Choosing active lifestyle in addition to maintaining of body mass index in the appropriate range and reduce body excess fat, it lead to control and prevention of the risk factors of Cardiac - Coronary disease and thus promotes physical health.
