the effect of physical activity on ctni, visceral fat, and plasma biomarkers of cardiovascular risk in shiftworkers of sarir plast industrial group

Background: shift work can be considered a cause of health problems and a risk factor for developing cardiovascular diseases. objectives: the purpose of the present study was to evaluate the effect of aerobic physical activity on ctni, visceral fat and plasma biomarkers of cardiovascular disease risk among shift workers of sarir plast industrial group. methods: the present research is a semi-experimental research that was carried out on the shift workers of the sarir plast industrial group. thirty workers, with an average of 5 years of shift work history, were selected through judgmental sampling technique and were then randomly assigned to the two groups of aerobic physical activity (n = 15) and control group (n = 15). based on the schedule, the experimental group performed 8 weeks, 3 sessions per week with 50% - 70% thr intensity. both before and immediately after the plan, the activity, height, bw, vf, ctni, tc, tg, hdl, ldl, vldl and vo2, max were measured. for data analysis, kolmogorov-smirnov test, levene’s test, mbox-test, and ancova were employed (p < 0.05). results: the bw, vf, tc, tg, and ldl significantly decreased in the post-test for the experimental group, while the value of hdl and vo2, max increased. however, ctni and vldl did not change significantly (p < 0.05). conclusions: aerobic physical activity was effective in reducing the risk factors of cvd in shift workers. it appeared that aerobic physical activity could be used as a non-pharmacological approach to prevent cvd in shift workers.
