The purpose of this research were to define interrelationship with Sasang constitution and physique, physical fitness, body composition, personality type of University students and provide reference data for developing a exercise program based on Sasang constitution The subjects of this research are total 350 persons of University students, who were consisted of 30 persons of Taeeumin and 29 persons of Soyangin and 27 persons of Soaimin except no persons of Taeyangia 218 persons were excluded from the study because they contained unnecessary answers about papers or the persons who disappeared Sasang constitution through the first and second diagnosis test, Measurement variables were consisted of 7 regions of the physique and 9 factors of the physical fitness by strength(2)/ muscular endurance(2), flexibility(l), balance(l),agility(l), cardiovascular endurance(l), speed and power(l) and 5 factors of the body conposition by Dual Energy X-ray Absorptiometry: DEXA and 8 types of personality type by Myers-Briggs Type Indicator( MBTI).These data were analyzed by the One Way ANOVA and Crosstab Analysis, using Windows SPSS/PC 12.0 specific program. The results were summarized as follows;1. In the relationship of physique and Sasang constitution, Taeeumin's body weight was heavier compared with other kinds of constitutions with significant level. And in the neck, chest, wrist and hip circumference Taeeumin was significantly higher than other constitutions(p<.05).2. In the relationship of physical fitness and Sasang constitution, Soyangin was superior to other constitutions in muscular endurance and flexibility(p<.05).3. In the relationship of body conposition and Sasang constitution, Taeeuinin was significantly higher than other constitutions in bone mass component, bone mass density, total fat mass, fat free mass, fat mass(p<.05).4. In the relationship of personality type and Sasang constitution, each constitutions personality type only showed significantly differences only in the extraversion and introversion(p<.05).

본 연구는 폐경 여성을 대상으로 저강도와 중강도의 유산소 운동 시 발생되는 심혈관 반응을 검토하였다. 대상자는 폐경 전 여성 10명(45.3 ± 1.7세)과 폐경 여성 10명(52.4 ± 0.9세)으로 구분하여 저강도(30 watts)와 중강도(60 watts)의 유산소운동시 심혈관 반응을 측정하였다. 이 결과 수축기혈압, 이완기혈압, 평균동맥혈압은 폐경 전 여성에 비해 폐경여성이 높게 나타났으며, SV, HR, CO은 운동강도가 증가함에 따라 두 집단 모두 통계적으로 유의하게 증가하였다. TVC는 두집단 모두에서 증가했지만, 폐경여성에서 TVC 증가는 폐경 전 여성과 비교해서 낮았다. 따라서 폐경 여성에서 CO와 총 말초혈관저항이 동시에 증가하여 혈압이 과도하게 상승하는 것으로 사료되며, 폐경 후 여성의 과도한 심혈관 반응이 운동승압반사와 동맥압력반사의 역기능 때문이라고 판단되었다. The cardiovascular responses during exercise were regulated by two neural mechanisms, central command and exercise pressor reflex. The exercise pressor reflex is believed to evoke cardiovascular responses by mechanical and metabolic factors while skeletal muscles are contracting. The purpose of this study was to examine the effects of exercise pressor reflex on the cardiovascular responses with increasing exercise intensity from low (heart rate: 95-100 bpm) to moderate (heart rate 125-130 bpm) workload.Twenty middle aged sedentary women (10 premenopause and 10 postmenopause) were recruited for this study. All subjects were instrumented to measure the cardiovascular responses at low and moderate workload. Mean arterial blood pressure was significantly increased at moderate workload in postmenopausal women, while there was no difference in premenopausal women. Stroke volume (SV), heart rate (HR), and cardiac output (CO) were significantly increased in both groups with increasing workloads. Total vascular conductance was significantly increased with an increasing workload in both group, but the magnitude in postmenopausal women was abolished. Thus, excessive blood pressure responses were mediated via less peripheral vasodilation in postmenopausal women. Therefore, this study suggests that the abnormal pressor response to graded cycling exercise in postmenopausal women may be due to dysfunction of exercise pressor reflex Or/and arterial baroreflex.

본 연구는 수중체중법을 기준으로 한 대학 남자 럭비 선수 28명의 %body fat을 생체전기저항법(BIA), 이중에너지 X-선 흡수법(DEXA법), 피하지방두께측정법(SFT법), 수중체중법)과 비교 분석하고 인체측정법을 통해 %body fat의 정확한 측정을 위한 추정식을 제안하였다. 그 결과, 수중체중법을 기준으로 BIA(r=0.885), DEXA법(r=0.955), SFT법(r=0.926) 사이에 높은 상관(P<0.05)을 나타냈다. SFT법을 이용한 %body fat의 단순회귀분석을 통해 얻은 추정식은 Y=4.057+(0.307×복부)+(0.327×삼두)로 산출되었다(R2=0.883). 본 연구에서 개발한 대학럭비선수 %body fat의 추정식은 가장 상관이 높은 것으로 나타난 복부와 삼두를 이용하여 만든 것으로 SFT법을 이용한 럭비선수의 %body fat 추정 시 유효한 자료로 활용될 수 있으며, 또한 간단한 방법으로 측정할 수 있는 항목으로 사용의 용이성을 제고시켰다는 장점을 가지고 있다. The purpose of this study was to investigate whether the skinfold method(SFT) could accurately predict %body fat in rugby players. Twenty-eight rugby players from K university located in Gyung gi. were recruited for this study. All subjects underwent bioelectrical impedance analysis(BIA), dual energy X-ray absorptiometry(DEXA), SFT, and Underwater weighing method three times and then a gold standard used to predict %body fat in humans (Underwater weighing method) was compared to other methods. BIA, DEXA, and SFT methods were highly correlated with Underwater weighing method. However, DEXA method showed the highest regression to predict %body fat following BIA and SFT, respectively. The values obtained by DEXA were similar to that of Underwater weighting methods. Of seven parts of body measured by the SFT method, an abdominal part showed the most correlation with Underwater Weighing method(r=0.931). Moreover, a regression equation created by two abdominal and triceps parts was Y=4.057+0.307 (X1)+0.327 (X2). R²=0.883 obtained by this equation showed highest regression from the most simple range. We conclude that to provide more possible and positive regression equation for rugby players, further studies are needed to include more subjects, body density, and regional body fat.

본 연구는 신체질량지수(BMI)에 기초한 과체중 노인 여성의 연령별 BMI와 경계성고혈압의 관련성을 검토하여 건강증진 기초자료로 활용하는데 목적이 있다. 노인여성 신체질량지수와 경계성 고혈압자의 전체 그룹 중, 경계성고혈압 발생 확률이 48%로 나타났고, 26 kg/m2 이상인 경계성고혈압의 발생 확률이 93% 이상으로 나타났다. 노인 과체중여성을 대상으로 BMI와 경계성고혈압의 관련성은 BMI 26 kg/m2 이상인 그룹에서 경계성고혈압 발생 확률이 높게 나타났다. BMI와 수축기혈압(SBP)과 이완기혈압(DBP) 반응에서 통계적으로 유의한 관련성이 나타났다. 따라서 노인 여성의 BMI 26 kg/m2를 초과하는 노인 여성은 고혈압 가능성이 높고, 심혈관질환의 위험이 있을 가능성이 높은 것으로 사료되며, 본 연구를 통해 모든 연령에서 BMI와 경계성고혈압에서 상관관계가 있는 것으로 알 수가 있었다. The purpose of this study was to examine relationship between body mass index (BMI) and borderline hypertension in elderly overweighted women by age, and to provide basic data for health promotion. BMI of elderly women with borderline hypertension that was 48% probability. Moreover, elderly women with BMI greater than 26 kg/m2 has 93% probability of getting borderline hypertension. They are as high as 48%, and the probability goes to 93% when their BMI is greater than 26 kg/m2. Regarding relationship between BMI and borderline hypertension, first, a group of elderly women with BMI greater than 26 kg/m2 is highly associated with getting borderline hypertension. Second, there is a statistically significant correlation of BMI with both systolic blood pressure (SBP) and diastolic blood pressure (DBP). This study suggests that elderly women with BMI greater than 26 kg/m2 are more likely to suffer from hypertension and cardiovascular diseases, and there seems to be a relationship between BMI and borderline hypertension. In addition, it is necessary to conduct researches about waist measurements of elderly overweighted women by age.

이혜영(HyeYoungLee),노호성(HoSungNho),김종경(JongKyungKim),최현민(HyunMinChoi),박세정(SaeJungPark) 한국체육학회 2008 한국체육학회지 Vol.47 No.6

본 연구는 고혈압 전단계자와 혈압약을 복용하지 않는 고혈압자를 Dipper (주간에 비해 야간 혈압이 10% 이상 감소하는 경향을 나타내는 고혈압자)와 Non-dipper로 분류하여 1회성 유산소 운동(40분 동안 VO2max의 50% 강도의 걷기)을 실시한 후 24시간 활동 중 혈압 측정을 통해 혈압 변화를 검토하였다. 그 결과, Dipper는 1회성 유산소 운동 처치 후 24시간 수축기혈압이 유의하게 감소하였으나, 주간과 야간시간은 차이가 나타나지 않았다. 반면, Non-dipper는 1회성 유산소 운동 처치 후 24시간 수축기 혈압과 야간시간 수축기, 확장기혈압에서 유의한 감소가 나타났다. 따라서 본 연구에서 제시한 1회성 유산소 운동이 Non-dipping을 dipping 으로 바꾸는데 효과적인 것으로 사료되었다. This study was to investigate the effects of a single bout of aerobic exercise on the 24-hr blood pressure in men with dipping and non-dipping type blood pressure. Based on a 24-hr ambulatory blood pressure monitoring each participant was classified either dippers (n=9; 33.6±8.1 yrs) or non-dippers (n=10; 41.0±9.9 yrs). All the participants had two 24-hr ambulatory blood pressure monitoring sessions following both a control and an exercise (40-min treadmill walk at 50% of O2max) treatments in a randomized order. In non-dippers exercise reduced 24-hr SBP (133.5±10.0→129.1±10.0 mmHg) and night time SBP (129.4±10.5→123.1±10.0 mmHg) and DBP (83.9±13.9→78.5±12.1 mmHg) compared to its control. In conclusion, a single bout of exercise reduces 24-hr blood pressure in dipping and non-dipping type prehypertensive and hypertensive men. Furthermore, non-dippers exhibited the reduction in elevated night time blood pressure.
