Introduction: Among the non-communicable diseases, ­cardiovascular diseases are among the most important causes of death, worldwide. Exercise, by modulating hematological factors and fat profile can reduce the risk of cardiovascular disease and their complications. This study compares the hematological factors and fat profiles between active and inactive male workers.
Methods: To conduct this cross sectional and case-control study, a total of 82 workers from Mehriz Cement Factory were selected based on the available sampling method. According to Beck questionnaire, 48 workers assigned to the inactive and 34 workers assigned to the active group. After 12 hours from the last meal, 10 ml of venous blood of the workers was taken to analyze for hematologic variables (red blood cells, hematocrit, hemoglobin, white blood cells) and fat profile (Cholesterol, Triglyceride, HDL and LDL). To analyze the data, SPSS  software and independent t-test was used.
Result: The results showed that red blood cells, hematocrit, and hemoglobin were significantly higher in the active group than the inactive group (P-Value≤0.05). In addition, compared to the active group, triglyceride level in the inactive group was significantly higher (P-Value≤0.05), but the levels of cholesterol, high-density lipoprotein and low-density lipoprotein were not significantly different between the two groups.
Conclusion: Since physical activity can improve hematological factors and fat profile, workers are recommended to take benefits from regular exercise.
