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.

현대사회에 있어서 신체활동 연구의 주요 탐구과제는 ‘신체활동을 통한 교육’으로부터 ‘인간의 기본적인 움직임’을 목표로 하는 스포츠적인 움직임을 중심으로 한 생명 활동의 개념으로 급속히 변화되고 있는 추세이다. 이러한 환경변화에 대응하기 위하여 본학회는 ‘체육’적인 요소에서 ‘스포츠’적인 요소를 중심으로 한 학문적 정체성을 견고히 하고, 정기적인 학술지 발간과 학술활동을 통해 한국스포츠츠 문화의 발전과 학문적인 발전에 기여하는데 그 목적이 있다.
