The effect of combined resistance-aerobic and aerobic training on the coagulative factors of young healthy men

Blood hypercoagulability or thrombogenicity can be one of the main causes of the cardiovascular diseases in young population without traditional pathologic risk factors such as diabetes mellitus, hypertension or hyperlipidemia. The effect of aerobic exercise on coagulation and fibrinolysis has been studied extensively Regarding to the effectivness of resistance exercises to increase functional ability of men, the purpose of this study was to examine the effects of the combined aerobic-resistance and aerobic exercise on the coagulation activity of healthy young men. 30 young healthy sedentary men (20±5 years old) randomly divided in 3 groups: 10 in the combined, 10 in the aerobic and 10 in nontraining matched control groups The training groups subjects were engaged in a program included, ten session, three times per week, with submaximal intensity and 24 min for every session. The combined group had 12 min resistance exercise, followed by a 12 min aerobic exercise on cycle ergometer although aerobic group had only 24 min aerobic exercise on cycle ergometer. The results revealed that PT decreased and PTT increased in training groups. Fibrinogen decreased significantly in both training groups. It was concluded that both submaximal aerobic-resistance and aerobic exercises, decrease coagulation system activity in young healthy sedentary men.
