The effect of different intensity of resistance exercise on circulatory and vascular function

영어: The purpose of this study was to investigate the effect of different resistance exercise intensity on circulatory(heart rate, blood pressure) and vascular function(PGI2, ET-1). Twelve male subjects(age 42.7±4.91years, weight 75.8±5.82kg) were randomly assigned to high and low resistance exercise treatment by crossover design. The high resistance exercise treatment performed three sets at 5-7RM with 2min rest between sets and the low resistance exercise treatment performed three sets at 10-13RM with 2min rest. Resistance exercise composed of seated bench press, barbell shoulder press, pull down, back extension, sit up, leg curl, leg press, calf raise. Venous blood samples were taken from an antecubital vein by venipuncture at pre-exercise, recovery period(60minutes later immediately after exercise). Systolic blood pressure was significantly decreased by high intensity exercise at recovery period, but low intensity exercise did not induce any significant change. PGI2 was significantly increased by both high and low intensity resistance exercise but there are any significant change with different exercise intensity.
