          18∼20세 청년기 여자학생 14명중 7명을 임의로 선정하여 비훈련군으로 하였고 1년이상 신체운동을한 7명은 훈련군으로 하였다. 지구성 운동훈련이(Endurance Training) aerobic work capacity에 미치는 영향 및 혈청지질단백질의 농도(serum lipoprotical)와 최대하부하(submaximal work load) 및 최대부하(maximal work load)에서의 혈청지질 변화를 안정 상태와 비교하여 강도별로 규명하고자 한 결과는 다음과 같다. 1. 지구성운동 훈련을 받은 18세 여자학생의 V˙O_2 max는 54.71ml/kg·min으로 비훈련군 42.47ml/kg·min로 훈련군이 높았다. 2. HDL-C는 훈련군이 75.71mg/dl 비훈련군은 64.85mg/dl이었다. 3. 훈련군의 V·O_2 max 70%에서 HDL-C의 농도는 76.57mg/dl로 1.14%증가되었다. 비훈련군은 V·O_2 약 50%에서 66.28mg/dl로 2.2% HDL-C이 증가되었다. 4. HDL-C는 all out시에 안정시에 비교하여 양군 다 약 7% 증가되었다. 5. LDL-C는 훈련군에서 194.0mg/이 비훈련군 258.4mg/dl로 비훈련군이 33.2%가 훈련군보다 높았다. 6. TC는 훈련군·비훈련군 양군이 동일하게 177mg/dl로 나타났다. 7. TG는 훈련군 93mg/이, 훈련군은 111mg/dl이었고 운동강도가 증가됨에 따라 훈련군에서는 증가되었다. 8. FFA은 안정시의 혈청농도가 훈련군에서 0.276μEq/ι이며 비훈련군에서는 0.564μEq/ι로 비훈련군이 높았다. The result of the study on fourteen young females focusing on the effect of endurance training on aerobic work capacity and the comparison of serum ltpoprotein concentration and the change of serum each at there states; submaximal workload, maximal work load and at rest concerning the degree in analyzing is as follows: 1. V˙O_2 max of the endurance trained young female is 54.71ml/kg.min higher than 42.47ml/kg.min of the untrained. 2. HDL-C of the trained is 75.91mg/dl and the untrained is 64.85mg/dl. 3. The load of 1.14% increase to 76.57mg/dl of HDL-C concentration from 70% of V˙O_2 max a intensity among the trained while the untrained showed 2.2% increase to 66.28mg/dl of HDL-C concentration from exer 50% of V˙O_2 max intensity. 4. HDL-C of all out state increase about 7% compare that of the rest state in both groups. 5. LDL-C of the untrained 258.4mg/dl is 33.2% higher than 194.0mg/dl of the trained. 6. TC is 177mg/dl in both groups. 7. TG of the trained is 93mg/dl and the untrained is 111mg/dl. The increase of TG is found as the exercise intensity increases among the trained. 8. The concentration of FFA at rest is higher among the untrained as it shows 0.276μEq/ι while it is 0.564μEq/ι among the trained.

          비만고령자 여성에 있어서 8주간의 운동훈련이 체지방 , 심혈관계 체력 , 혈중지질 및 혈장 호모시스테인 농도에 관한 효과

          임미자 대한비만학회 2000 The Korean journal of obesity Vol.9 No.4

          Regular exercise has been known to prevent cardiovascular disease. Level of plasma homocysteine was considered to be one of independent risk factors of the cardiovascular disease. The purpose of this study was to investigate the effects of regular exercise on elderly obese women with measuring changes in BMI, %fat, skin fold, and cardiovascular fitness level (HR, BP, double product, VO2Max, 12 min running distance). 15 elderly obese women (mean age: 66.5±1.4 years) performed jazzercise for 8 weeks (60 minutes/day repeated 2 times per week). We measured pre and post exercise levels of BMI, %fat, abdominal skin fold thickness, cardiovascular fitness (HR, BP, DP, VO2max), 12 min running distance, lipid profiles, fasting glucose, insulin, HbAlc, and plasma homocysteine. Data were analysed with one way ANOVA and t-test. Abdominal and triceps skinfold thickness significantly decreased. There were tendancy to increase of VO2Max and decrease of Rest SBP, DBP, and double product after exercise. Also, Cholesterol and bAlC decreased significantly and plasma homocysteine concentration decreased without statistical significance. It was found that after eight weeks of exercise program, abdominal obesity was controlled and cardiovascular endurance level for elderly obese women was enhanced. Efforts to increase VO2Max and decrease homocysteine could reduce the risk of cardiovascular disease in the elderly obese women. Regular and continuos physical activities may be prerequisite to the elderly obese people and these could be beneficial to improve health-related physical activity.

          여자에게 월경주기의 sports training이 생리기능과 운동능력에 어떤 영향을 미치는가를 파악하기 위하여 평균연령 20세의 건강한 여자 대학생 10명을 대상으로 bicycle ergometer를 이용하여 max VO_2 45%, 70%, exhaution의 운동을 부하한 후 호흡계, SaO_2, 순환계 및 혈중유산과 혈액 성상을 난포기와 황체기에 각각 비교검토하여 다음과 같은 결과를 얻었다. 1. 체중당 최대 산소섭취량, 분당 환기량, 분당 호흡수, 환기당량(V˙E/V˙O_2), 호흡상(RQ) 등은 각각의 운동강도에서 (P<.001)로 유의있게 증가하였으나 난포기와 황체기 사이에서는 유의한 차가 없었다. 2. 분당 Co_2의 배출량은 최대 운동시 황체기 V˙Co_2 max 2.05±0.241/min 보다 난포기에 3.188±0.661/min으로 P<0.024 유의한 차이로 난포기에서 높은치를 나타냈다. 3. 動脈血酸素包和度(SaO_2)는 난포기에서 안정시 96%에서 최대작업시 91%로, 황체기에서는 안정시 96%가 최대작업시 90%로 낮아졌으며(P<.05), 강도와 기간간에서 P>.01로서로 상호작용이 있었다. 4. 回拍出量(SV)은 test2에서 난포기에 113.5±32ml/beat로 황체기에는 120.3±35.1ml/beat에서 levelling off 되었으며 황체기에서 안정시 및 test1, 2와 Exhaustion시에 높은치를 나타냈다. 5. 心拍出量(Q˙)과 心拍數(HR)는 각각의 강도별 양기간에 유의하게 증가했다(P<.001). 6. 全電氣的 機械的 收縮期(Q˙S_2), 前驅出期(PEP) 및 左心室驅出時間(LVET)은 안정시 보다 각각의 운동강도에서 유의하게 (P<.001) 저하 되었으나 난포기 및 황체기에서의 차이는 유의하지 않았다. 7. PEP/LVET는 양기간에 차이는 없으나 최대 운동시에는 저하되어 좌심실기능 저하를 보였다. 8. 血中乳酸値 LA는 난포기 안정시 1.33±0.37mM/1, 황체기(B) 안정시에는 1.29±0.23mmol/l였으나 최대작업기에 난포기에서는 10.78±1.91mmol/l, 황체기에서는 11.39±2.08mmol/l로 황체기에서 높은치를 나타냈으나 양기간에 유의한 차는 없었다. 9. WBC, RBC, Hb, Hct는 각각의 운동강도에서 난포기 및 황체기에 유의하게 증가하였으나 양기에 차이는 없었다. 이상의 결과를 보아 여성의 생식 생리기간별로 운동시에 각 기관별 기능에는 차이가 없으나 V˙CO_2 및 SaO_2등은 난포기에 유의하게 높았으므로 심리적인 영향이 身體狀態(condition)를 좌우하는 것이라 사료된다. The study is on the relationship of cardio-respiratory, SaO_2 the blood distribution and lactate with the exercise training during the follicular and luteal phases of the menstrual cycle. The influence of sports training on the menstrual cycle was investigated by means of the bicycle cycling of college females in this study. The subjects were trained at the exercise load of 45%, 70%and max V˙O_2 during the follicular and the luteal phases of the menstrual cycle. The volume of oxygen uptake was measured by the Douglas bag analyzer method. The saturation of the arterial oxygen(SaO_2) was measured by using an ear oximeter of Hewlett Packard at rest and each workload. The Cardiac output was determined by using the Impedance cardiographic method at rest and each work load; blood samples were collected to measure the blood composition(RBC, WBC, Hb, Hct) and lactic acid concentration at rest, test 2 and test 3. The results of the experiment is as follows: 1. As each work load increased, O_2 up-take, ventitation, heart rate, etc. significantly increased, on the other hand, there was no significant change in O_2 up-take, ventilation, heart rate, etc. during the two phases. 2. At the maximal work load the amount of CO_2 production was high during the Follicular phase(The significant difference was p<0.0024) and low during the follicular phase. That of the follicular phase was 50% higher than that of the luteal phase(3.188±0.65 VS 2.051±0.24 l/min). 3. The amount of SaO_2 was 96% at rest, and 91% at maximal work during the luteal phase(p<0.05). During the follicular phase, the amount of SaO_2 was 96.4% at rest, and 90.3% at the maximal work. The significant difference of the inter-relationship between the work loads and the two phases was revealed as p<0.01. 4. The stroke volume was levelled off 113.5±32ml/beat during the luteal phase, and the level of the stroke volume was 120.3ml/beat during the follicular phase at test 2. At test 3 the two phases decreased, but there was no significant difference. 5. The cardiac output(Q˙) increased along with V˙O_2 and HR during the exercise, but there was no difference during the two phases. 6. The total electro mechanical systol (QS_2), pre-ejection period(PEP), left ventricular ejction time(LVET), and PEP/LVET ratio decreased in the similar pattern as the work load increased during the two phases. 7. As for the lactic acid concentration the value of 1.33±0.37mmol./l at rest increased to 10.78±1.9mmol/l at the maximal work during the luteal phase, and 1.29±0.23mmol/l at rest to 11.39±2.08mmol/l at the maximal load in the follicular phase. In genernal the value was higher during the follicular phase than during the luteal phase. However there was no significant difference during the two phases. 8. WBC, RBC, Hb, Hct increased during the two phases. There was, however, no significant difference during the two phases. In conclusion, the aerobic performance and the cardio-respiratory adaptation were not influenced by the exercise during the two phases of the menstrual cycle. In cardio-respiratory response to the exercise, aerobic capacity was same during the two phases of the menstrual cycle. V˙CO_2 is lower during the follicular phase. SaO_2 is lower during the luteal phase, and lactic acid concentration is lower during the follicular phase, which means that physical condition is felt better during the follicular phase than the luteal phase.
