Abstract

The purpose of this study was to investigate the effects of maximum and endurance resistance exercises on total work, blood viscosity, and erythrocyte volume ratio. The study subjects were selected as 15 men in their twenties with 12 months or more of resistance exercise experience, and the bench press 1RM was measured before the experiment, and the experiment for each condition was cross-allocated at intervals of one week, and the maximum repetition was performed in 6 sets. As a result, the total amount of exercise showed that the muscular endurance strength was higher than that of the maximum muscular strength (p<.001), and the blood viscosity and erythrocyte volume ratio were higher after exercise than before (p<.01) regardless of the total exercise amount. In summary, it was found that blood viscosity was not affected by exercise intensity and amount of exercise, and increased with one-time resistance exercise. This is clinically significant in constructing a resistance exercise program, and it is considered to be a reference material in creating an exercise program for clinical patients related to vascular disease.

이 연구는 최대근력형과 근지구력형 저항운동이 총운동량과 혈액점도 및 적혈구용적률에 미치는 영향을 조사하고자 하였다. 연구대상자는 저항운동 경력 12개월 이상의 20대 남성 15명으로 선정하였으며, 실험 전 벤치프레스 1RM을 측정하였으며, 조건 별 실험은 1주일간의 간격을 두고 교차배분하여 6세트 씩 최대반복수행 하였다. 그 결과 총운동량은 근지구력강도가 최대근력강도에 비해 높게 나타났으며(p<.001), 혈액점도와 적혈구용적률은 총운동량에 관계없이 운동 전보다 운동 후에 높아졌다(p<.01). 종합하면 혈액점도는 운동강도와 운동량에 영향을 받지 않으며, 일회성 저항운동으로 증가한다는 것을 알 수 있었다. 이는 저항운동 프로그램을 구성하는데 있어 임상적으로 의의가 있으며 혈관질환에 관련된 임상환자들의 운동프로그램을 작성하는데 있어 참고자료가 될 수 있을 것으로 판단된다.
