تأثیر چهار هفته تمرینات دایره‌ای بر فیبرینوژن پلاسما در کشتی‌گیران

Background and Objective: Scientific findings are noted began occurrence of risk factors in childhood particularly concerned with changes in the pattern of body mass index (BMI) and lifestyle. Evidence suggests that some people, despite having normal cholesterol, high density lipoprotein (HDL) and low density lipoprotein (LDL) levels, are still prone to cardiovascular disease. However, those at risk for clinical detection of atherosclerotic heart disease (CHD) should be specifically evaluated for certain clinical indicators. The purpose of this study is to document the effect of a four weeks circuit training program on the level of plasma fibrinogen in trained wrestlers. Materials and Methods: This quasi-experimental study was performed on 20 young wrestlers from Khorasan (mean age 19.7 years, BMI 25.5 kg/m2 and 3 to 5 years experience in wrestling) in 2012. Subjects during the Calling, voluntarily chosen and randomly divided into control (n=10) and experimental (n=10) groups. Subjects of experimental group received eight sessions per week for four weeks (four days in the morning and evening shifts) were exercised that each training session was dedicated to wrestling and circuit training based on wrestling techniques. Subjects of control group did not perform any exercise in four weeks. Weight, body fat percentage, BMI and fibrinogen were measured before and after exercise. Independent two-sample t-test and paired t-test were used compare variable mean. Results: The Results showed that subjects of experimental group in the amount of body fat, (7% decrease p=0.002) weight (3.5% decrease p<0.001), BMI (2% decrease p<0.001), and fibrinogen (8% decrease p=0.014) significantly reduced after circuit training. Conclusion: Generally four-week circuit training based on wrestling techniques significantly reduced plasma fibrinogen and appears to reduce body fat percentage of subjects (which is evident in this study) is the reason for the decrease in plasma fibrinogen in experimental subjects which ultimately leads to reduced risk of coronary artery disease and ultimately reducing heart strokes in athletes.
