Abstract

This study sought to investigate interrelationships and differences of brachial-ankle pulse wave velocity (baPWV), body composition and cardiovascular variables between genders who have been exercised or not in elderly. One hundred fifty participants were classified four groups. Especially out of variables, in male elderly group who had participated in exercise program the PWV range were significantly correlated with muscle mass (r=0.357, p=0.026), SBP (r=0.468, p=0.003), right baPWV (r=0.406, p=0.010), and left baPWV (r=0.333, p=0.038). In male elderly group who had not participated in exercise program, the PWV range were significantly correlated with heart rate (r=0.395, p=0.014), right baPWV (r=0.598, p=0.000), and left baPWV (r=0.602, p=0.000). In female elderly group who had participated in exercise program, the PWV range were significantly correlated with name of diagnosis (r=0.321, p=0.044), SBP (r=0.399, p=0.011), DBP (r=0.545, p=0.000), right baPWV (r=0.648, p=0.000), and left baPWV (r=0.676, p=0.000). In female elderly group who had not participated in exercise program, the PWV range were significantly correlated with age (r=0.471, p=0.003), right baPWV (r=0.836, p=0.000), and left baPWV (r=0.801, p=0.000). The PWV among four groups were not significant different after experiment. However, there were significant differences in the waist/hip ratio (F=9.197, p=0.000), muscle mass (F=74.295, p=0.000), and %fat (F=35.045, p=0.000) from body composition. And there were significant differences in the SBP (F=3.525, p=0.017) after experiment. In conclusion, these data show that regular exercise is associated with arterial compliance (PWV range, right or left PWV) and differed from genders. In other words, this paper may support the concept that regular exercise program may exert a protective effect on arterial compliance, body composition and cardiovascular systems.

심혈관계 위험인자를 비침습적으로 분석할 수 있는 PWV에 관한 다수의 선행연구에서 의견이 분분하고, 결과에 대한 일관성이 부족한 부분을 재현하고자 연구에 임하였으며, 더욱이 날로 증가하고 있는 노인을 대상으로 운동참여 여부와 성별에 따른 노인의 말초동맥파속도(baPWV), 신체구성과 심혈관계 변인의 상관성 및 재변인의 차이를 검증하는데 연구의 목적이 있다. 규칙적인 운동을 수행해온 노인남성 39명(이하, 운동군M) 과 운동을 수행해 오고 있지 않은 동일 연령대의 노인남성 38명(이하, 통제군M), 규칙적인 운동을 수행해온 노인여성 40명(이하, 운동군F) 과 운동을 수행해오고 있지 않은 동일 연령대의 노인여성 37명(이하, 통제군F)을 대상으로 변인에 대한 상관성과 집단별 재변인들 간의 차이를 알아본 결과 노인남성 운동군의 baPWV range와 근육량(r=0.357, p=0.026), 수축기혈압(r=0.468, p=0.003), rbaPWV (r=0.406, p=0.010), lbaPWV (r=0.333, p=0.038)가 통계적으로 유의한 상관관계를 보였고, 노인남성 통제군의 경우는 baPWV range와 심박수(r=0.395, p=0.014), rbaPWV (r=0.598, p=0.000), lbaPWV (r=0.602, p=0.000)가 유의한 상관성을 보였다. 노인여성 운동군은 baPWV range와 진단명(r=0.321, p=0.044), 수축기혈압 (r=0.399, p=0.011), 이완기혈압(r=0.545, p=0.000), rbaPWV (r=0.648, p=0.000), lbaPWV (r=0.676, p=0.000)가 유의한 상관성을 보였고, 노인여성 통제군 경우는 baPWV range와 나이 (r=0.471, p=0.003), rbaPWV (r=0.836, p=0.000), lbaPWV (r=0.801, p=0.000)가 통계적으로 유의한 상관성을 보였다. 반면 말초동맥파속도 변인 중 통계적으로 유의한 차이를 보인 그룹은 없는 것으로 나타났고, 요둔위($F_{3,150}=9.197$, p=0.000), 근육량($F_{3,150}=74.295$, p=0.000), 체지방율($F_{3,150}=35.045$, p=0.000), 수축기 혈압($F_{3,150}=3.525$, p=0.017)이 통계적으로 유의한 차이를 나타냈다. 본 연구에서는 집단별 특성에 따라 다양한 결과가 나타난다는 사실을 알 수 가 있었으며, 신체구성 변인과 심혈관계 변인 중 수축기 혈압은 운동 여부에 따라 민감한 변화와 차이를 보인 것으로 보아 노인의 경우 운동그룹은 신체구성과 심혈관계 일부 변인에 변화를 줄 수 있다고 단정지어 볼 수 있겠으나, 위팔-발목 맥박파전파속도에 대해서는 일관된 결과가 도출되지 않아서 이에 대한 지속적인 연구가 필요한 것으로 사료된다.
