신체질량지수에 따른 20대 남,여의 운동부하 검사 후 심박수 회복률과 맥파속도 비교 = Comparison of Pulse Wave Velocity and Recovery Rate of the Heart Rate after Graded Exercise Test to Body Mass Index in Their Twenties.

다국어 초록 (Multilingual Abstract)

This Study is intended to compare the recovery rate of heart rate with the pulse wave velocity in after conducting the graded exercise test for each group of overweight people and underweight ones according to each BMI (Body Mass Index). The recovery rate of heart rate was measured every 30seconds at each maximal heart rate after each graded exercise test and then the pulse wave velocity of each person was measured after completing the measurement of heart rate of each person. Accordingly, as the results from the measurements, first, it was found that the recovery rate of heart rate of the overweight groups of males and females was faster than that of the underweight groups after conducting a maximal graded exercise test for each group, that is, the underweight and overweight groups of males and females. And the results were significant statistically. Second, the pulse wave velocities of the overweight groups of male and females showed some difference between the average values after conducting the maximal graded exercise test for each group, but the results were not significant statistically. As the results of this Study shown as above, it was found that the recovery rate of heart rate of each group is related to the BMI of each person and the average values of the pulse wave velocities of all the groups were different, but the differences were not significant statistically. Thus, it was found that the cardiovascular system of the overweight groups of males and females is much healthier than that of the underweight groups of males and females after measuring the recovery rates of heart rates and the pulse wave velocities of all the groups as the predictive factors for a disease of the cardiovascular system of a human being.

본 연구는 신체질량지수에 따라 과체중과 저체중 집단에게 운동부하 검사 후 심박수 회복률가 맥파속도를 비교하는데 그 목적이 있다. 운동 부하 검사 후 최대심박수에서 30sec단위로 심박수의 회복률을 측정하고 맥파속도를 측정하였으며 다음과 같은 결과를 도출하였다. 이에 측정한 결과는 첫째, 남성과 여성의 저체중과 과체중 집단 간의 최대 운동 부하검사 후, 심박수 회복률은 과체중 집단이 빠른 회복률을 보였으며, 통계적으로 유의하였고, 둘째, 남성과 여성의 저체중과 과체중 집단 간의 최대 운동 부하검사 후, 맥파속도는 과체중 집단이 평균값의 차이를 보였으나, 통계적으로는 유의하지 않았다. 이와 같이 본 연구 결과, 신체질량지수에 따른 심박수 회복률은 관련성이 있었으며, 맥파속도는 평균값의 차이를 보였으나 통계적 유의차를 나타내지 않았다. 심혈관계의 질환의 예측인자인 심박수 회복률과 맥파속도의 측정을 통해 남성과 여성 집단 모두 저체중 집단에 비해 과체중 집단이 심혈관계가 건강하다는 것을 알 수 있었다.
