Cardiovascular Factors, Heart Events, and Training Habits of Middle-aged Marathon Runners with Exercise-Induced Hypertension
The purpose of this study is to investigate cardiovascular factors, heart events, and training habits of runners with EIH. The subjects were runners who had at least two-year experience in marathon and at least five times of completion, and they were divided into group of normal blood pressure in resting and <200㎜Hg in maximal volition period in exercise stress test (group A), group of 200-219㎜Hg (group B), and group of ≥220㎜Hg (group C). The results of this study are as follows. As for cardiovascular factors, there were no differences among the groups in RHR, MHR, RDBP, MDBP, VO2max, and MT, while RSBP was significantly higher in group B and C than group A (p<.001). As for heart events, there were no differences among the groups in myocardial ischemia and arrhythmia occurrence, 4.1% and 1.7%, respectively. As for training habits, there were no differences among the groups in training frequency, but training intensity was significantly higher in group C than group A and training hours was significantly higher in group C than group A and B. Significant correlation was shown between MSBP and training intensity (r=0.15, p=0.019) and between MSBP and training hours (r=0.30, p=.000), respectively.However, there were no differences among the groups in exercise career, number of completion, and completion records. In Conclusion, Training intensity and training hours were significantly higher in EIH runners with significant correlations with maximal blood pressure. Confirmation on the correlations should be verified through additional examinations of echocardiography, arterial stiffness, and endothelial function. Also, the subjects generally showed severe myocardial ischemia and arrhythmia, needing periodic exercise stress test for preventing sudden death.

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.
