많은 사람들이 건강증진을 위해 정기적인 신체활동에 참여하고 있다. 정기적인 신체활동 참여를 통해 체중감소와 건강한 체중을 유지시켜 궁극적으로 현대사회의 가장 큰 문제점인 비만을 해결할 수 있다. 대부분의 사람들은 운동수행 중 체중을 중요한 건강지표로 인식하여 건강상태를 평가하고, 목표체중을 선정하여 운동을 수행하고 있다. 그러나 지나친 체중에 대한 집착은 극단적인 다이어트나 과도한 운동이라는 잘못된 습관을 야기 시킨다. 뿐 만 아니라 건강한 체중감소가 이루어지기 위해서는 장기간의 정기적인 신체활동 참여가 필수적이다. 본 총론은 규칙적인 신체활동 참여를 통해 단기적으로 체력이 증진되고, 대사성질환 위험요인들을 건강한 수준까지 감소되며, 장기적으로 비만도가 건강한 수준까지 감소되기 때문에 지나친 체중조절에 대한 집착보다는 체력증진의 효과를 기대할 것을 제안하고 있다. Participating in regular physical activity is recommended for health promotion. Physical activity participation produces weight loss and healthy body weight maintenance, and essentially the prevalence of obesity decreases. Most people utilize the body weight as physical activity motivation or goal; however, some of them engages in over-exercise or extreme diet in order to extreme weight loss in relatively short period of time. The current review study demonstrates that regular physical activity participation increases health related physical fitness is associated with risk factors of metabolic disorder including blood pressure, glucose, triglyceride, cholesterol and insulin during short period of time, and produces the appropriate amount of weight loss during long period of time.

Physical activity means movement of body with skeletal muscle that uses energy. Physical activity plays an important role in health promotion in physical, mental and social dimensions. Generally, exercise prescription is necessary since anyone can do exercise safely and efficiently. First step, physical activity assessment is required for efficient exercise prescription with physical activity assessment devices including physical activity questionnaire, pedometer, heart rate monitor or accelerometer. The purpose of the current study was to introduce and review actigraph. Actigraph, an accelerometer, is a non-invasive device of monitoring human activity. This device consists of a timer to start or stop at specific times and to accumulate values for a specific time frame, a memory to store the resulting values and an interface to download the data from memory. However, there are several limitations in the current version of actigraph such as the inaccurate equation to calculate energy expenditure in a variety levels of exercise intensity, the place to wear and the period time of wearing.

이 연구의 목적은 국민체력인증제 시범사업에 참여한 건강한 성인남녀를 대상으로 건강체력 뿐 아니라 기능체력을 포함한 총체력과 심혈관계질환 위험도와의 관련성을 분석하고, 근력과 심폐지구력이 독립적으로 심혈관계질환에 미치는 영향을 조사하는데 있다. 국민체력인증제에 참여한 건강성인(n=150; 여자 49.3%)을 대상으로 혈액검사와 신체조성, 건강체력(악력, 윗몸일으키기, 20m 왕복오래달리기, 앉아윗몸앞으로굽히기) 및 기능체력(10m×4회 왕복달리기, 제자리멀리뛰기)을 측정한 후, 근력지수와 총체력 지수는 해당항목 점수를 표준점수화(z-score)하여 산출하였다. 심혈관계질환 위험도는 성별에 따라 혈압, 총콜레스테롤, 고밀도지단백콜레스테롤, 당뇨 및 흡연여부, 나이 등을 고려한 프래밍함 위험점수를 사용하여 추정하였다. 그 결과, 남자는 심폐지구력만이 프래밍함 위험점수의 독립적 위험요인(ß=-0.297, p<0.05)으로 나타났으나, 여자는 심폐지구력(ß=-0.314, p<0.05)과 근력(ß=-0.366, p<0.05) 모두 독립적 위험요인으로 나타났다. 남자는 심폐지구력(p<0.05) 및 총체력(p<0.01) 수준에 따라 프래밍함 위험점수에 차이가 나타났으며, 심폐지구력과 총체력 최저수준그룹에서 프래밍함 위험점수가 높았다. 반면, 여자는 심폐지구력(p<0.001)과 총체력(p<0.001)은 물론 근력(0.001)까지 각각의 수준에 따라 프래밍함 위험점수의 차이를 보였으며, 근력, 심폐지구력 및 총체력 최저수준그룹에서 프래밍함 위험점수가 높았다. 이상의 결과를 종합해 보면 여자는 심폐지구력 뿐만 아니라 근력 또한 심혈관계질환의 독립적 위험요인임을 알 수 있었다. 또한, 성별에 관계없이 건강한 성인에게 건강체력과 기능체력을 포괄한 총체력이 심혈관계질환 위험도와 관련이 있었으며, 이는 심혈관계질환 예방에 있어 총체력의 향상노력이 중요함을 시사한다. The purpose of this study was to examine the relationship between coronary heart disease (CHD) risk and fitness including both health-related and skill-related physical fitness in healthy adults. National Fitness Award participants performed a total physical fitness (TF) testing (hand-grip strength, sit-ups, 20m shuttle run, sit and reach, shuttle run and long jump). Among the National Fitness Award participants the ones (n=150; 49.3% women) were able to be identified CHD risks included in this study. The indexes of MF (sum of the z scores for relative grip strength and sit ups) and TF (sum of the z-scores for all fitness factors) was calculated. The CHD risk was assessed by the 10-year Framingham CHD risk score (FRS) for CHD. The results were following:In men CRF was an independent risk factors for CHD (ß=-0.297, p<0.05). In women, however, both CRF (ß=-0.314, p<0.05) and MF (ß=-0.366, p<0.01) were all independent factors for the CHD risk. Furthermore, significant differences were found in the CHD risks among the levels of CRF (p<0.05) and TF (p<0.01), respectively, but in MF in men. The lowest levels of CRF and TF presented higher CHD risk in men. In women, however, there were significant differences in the CHD not only among the levels of CRF (p<0.001) and TF (p<0.001) but also MF (p<0.001). The lowest levels of MF, CRF and TF presented higher CHD risk in women. In conclusion, muscle fitness as well as cardiorespiratory fitness was independently associated with the CHD risk in healthy women. total fitness which was including both health-and skill-related was associated with risks of CHD in men and women. These results support current physical activity for adults which include muscle strengthening exercise in addition to aerobic activities.
