단기간의 심혈관 지구성 운동이 신체 구성 및 혈압에 미치는 효과 = Effects of Short-Term Cardiovascular Endurance Exercise on Body Composition and Blood Pressure

다국어 초록 (Multilingual Abstract)

Background: Regular exercise can help in the prevention and treatment of such diseases. However, most individuals exercise only rarely or irregularly. This study examined the effects of short-term cardiovascular endurance exercise on body composition and blood pressure in adults who visited an exercise prescription clinic.
Methods: From among 505 adults who visited the University Hospital family medicine and exercise prescription clinic from March 2005 to March 2011, data of 105 adults who regularly participated in the cardiovascular endurance exercise program were collected and analyzed. Changes in body composition and blood pressure were measured before and after the 8-week exercise program (types of exercise: stationary bicycles and treadmills; exercise intensity: 60%–85% maximum oxygen consumption; exercise frequency: 3–5 times a week; and exercise duration: 20–45 minutes per session).
Results: Obesity, as defined by the percentage of body fat (measured by bioimpedance analysis), was 71.4% and 80.5% for male and female, respectively, and obesity, as defined by body mass index, was 53.5% and 40.2% for male and female, respectively. Percentage of body fat, body mass index, weight, abdominal circumference, diastolic blood pressure, and systolic blood pressure were statistically significantly lower after the exercise program. In addition, with the exercise program, the waist-hip ratio decreased and the lean body mass increased. However, the differences were not statistically significant.
Conclusion: Short-term cardiovascular endurance exercises can have a positive effect on body composition and blood pressure. Therefore, doctors should more actively recommend exercise guidance.

연구배경: 운동 부족이 각종 성인병 및 만성질환과 밀접한 관련성이 있고 규칙적인 운동이 이러한 질환의 예방과 치료에 도움이 된다는 증거들이 알려져 있지만 대부분의 사람들은 운동을 거의 하지않거나 불규칙하게 운동에 참여하고 있다. 본 연구는 운동 처방 클리닉을 방문한 성인들을 대상으로 하여 비만의 정도와 단기적인 심혈관 지구성 운동의 신체 구성 및 혈압에 대한 효과에 대해 알아보았다.
방법: 2005년 3월부터 2011년 3월까지 대학병원 가정의학과 운동 처방 클리닉을 방문한 성인 505명 가운데 8주간 규칙적으로 심혈관지구성 운동 프로그램(운동종류: 고정식 자전거 및 러닝 머신, 운동강도: 60%–85% 최대산소 섭취량, 운동횟수: 주 3–5회, 운동지속시간: 20–45분)에 참여했던 105명에 대해서 운동 전후의 신체 구성 및혈압의 변화를 비교 분석하였다.
결과: 대상자중 체지방률(bioimpedance analysis)에 따른 비만은 남녀각각 71.4%, 80.5%였고 체질량지수에 의한 비만은 각각 53.5%,40.2%였다. 체질량지수, 체지방률, 체중, 복위, 이완기 혈압 및 수축기 혈압이 운동 전에 비해 운동 후 측정치가 통계적으로 유의한 감소를 보였다. 운동 후 복위-둔위 비(waist-hip ratio)는 감소하였고 제지방량(lean body mass)은 증가한 결과를 보였지만 통계적 유의성은없었다.
결론: 단기간의 심혈관 지구성 훈련으로도 신체 구성과 혈압에 좋은 영향을 줄 수 있기 때문에 의사가 좀 더 적극적으로 운동 권유및 운동 지도를 해야 하며 앞으로 이에 대한 더 많은 연구와 검증이필요할 것으로 생각된다.
