최대근력 저항운동과 근지구력 저항운동시 총운동량;혈액점도 및 적혈구용적률의 변화

Changes in Total Work;Blood Viscosity and Hematocrit during Maximum Strength Type and Endurance Type Resistance Exercise

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.

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.
