The purpose of this study was to prediction of the maximal oxygen uptake by using echocardiography. The sample consists of 18 male athletes and 18 non-athletes. The athletes were long distance and marathon runners, and non-athletes were not participating in any athletic program. Rest echocardiography was used to measure left ventricular variables(LVIDd, LVIDs, PWT, SWT) and maximal matabolic capacity by incremental exhaustion exercise were used to assess maximal oxygen uptake in all subjects. Two-way ANOVA, simple regression analysis, and multiple regression analysis were conducted for the statistical analysis. On the basis of the results analyzed in the study, the conclusion could be drawn as follows : 1. Maximal oxygen uptake in athletes was significantly higher compared to non-athletes, and rest echocardio- graphically measured left ventricular variables(LVIDd, LVIDs, PWT, SWT, LVEDV, LVESV, SV, LVM) were higher in athletes and adults. 2. Using Simple regressions analysis, R-squares to explain maximal oxygen uptake as left ventricular variables were higher in athletes than in non-athletes. 3. By using multiple regression analysis formula for athletes was Y=-1.950720+0.081399 LVIDd-0.263412 PWT+0.444841 SWT(r^2=42.74%) and formula for non-athletes was Y=-6.333901+0.116192 LVIDd-0.443447 SWT(r^2=61.88%). In conclusion, the effects of sustained long-term endurance training caused to changes of the heart size in rest and maximal exercise, and there was closely relationship between heart size and maximal oxygen uptake. Thus echocardiographic study could be applied to sport medicine field as the indirect method to obtain the maximal oxygen uptake.

This study is to investigate the correlation between obesity and growth hormone and IGF- I, and the change of these hormones by exercise program. For this, we selected 22 obese children and 17 normal weight children aged 10~12. First of all, we analyzed the difference of these hormones between obese group and normal weight group by independent t-test, and the correlation between several indexes of obesity and these hormones. Among these subjects, obese group was divided into two groups, exercise group and non-exercise group. The children of exercise group carried on exercise program 40 minutes, three times a week for 10 weeks and the change was analyzed by repeated measures ANOVA. The conclusion was that the concentrations of growth hormone and IGF- I of obese group are lower than those of normal weight group significantly and especially the rate of abdominal fat among several obese indexes showed relatively strong correlation with these hormones. As the result of exercise program, there were no significant differences between the groups in growth hormone and IGF- I even though there were significant differences in the changes of % body fat, the rate of abdominal fat, the degree of obesity and BMI. But, the attention should be taken in inducing conclusion because there would be several factors influencing the results like individual physiological conditions and the contents of exercise, and the degree of correlations between these hormones and the indexes of obesity were somewhat low.

생리적 변인에 대한 장기간의 훈련 효과를 알아보았다. 대상은 15세부터 28세까지의 남성으로 지구력 훈련을 장기간 지속적으로 해온 운동 선수 집단(21)과 운동 프로그램에 참여한 경험이 없는 일반인 집단(18)으로 나누었으며, 각각 중학교, 고등학교 및 일반 성인집단으로 세분하였다. 모든 피보험자에 대해 안정시 생리적 변인들을 측정하였고, 최대 산소 섭취량을 측정하기 위해 점증적 탈진 운동에 의한 최대 대사 능력을 알아보았다. 자료의 처리를 위해 two-way ANOVA를 사용하였으며, 연구의 가설 검증에 대한 유의도 수준을 5%로 하였다. 결론적으로, 운동 선수 집단과 일반인 집단의 신체적 조건을 유사하게 고려하더라도 지속적인 장기간 지구력 훈련의 효과는 안정시와 최대 운동시의 생리적 변인에 큰 영향을 미친다고 하겠다. The purpose of this study was to investigate the effect of long-term athletic training on the physiological variables. The sample consists of 21 male athletes and 18 non-athletes. 7 male athletes and 6 non-athletes were selected in the following three respective categories : middle school, high school, and adult(aged 15 to 28 years). The athletes were long distance and marathon runners and non-athletes not participating in athletic program. Rest physiological variables were measured and maximal matabolic capacity by incremental exercise were used to assess maximal oxygen uptake in all subjects. Two-way ANOVA were conducted for the statistical analysis. The 5% level of significance was used as the critical level for acception of hypotheses for this study. On the basis of the results analyzed in the study, the conclusion could be drawn as follows: 1. Rest heart rate and rest systolic blood pressure were significantly lower in athletes than in non-athletes, and adults(marathon runners) lowest. 2. Maximal systolic blood pressure were significantly higher in athletes than in non-athletes, and adults(marathon runners) highest. 3. Maximal oxygen uptake in athletes was significantly higher compared to non-athletes.

The purpose of this study was to investigate the effects of blood leptin level reducing the body fat and BMKbody mass index). The percent body fat of subjects was over 33.30±3.05(%), and their ages were 20.12±1.54(y) in 22 female college students. After aerobic exercise for twelve weeks blood leptin level was significantly decreased 11.89±4.40(㎎/dl) to 7.68±3.36(㎎/dl)(p=0.0001). It is not certain whether the decrease of blood leptin level effected to reduction of the body fat weight or the reduction of the body fat weight effected to the decrease of blood leptin level. However, blood leptin level and body fat weight effected to each other and the weight loss by aerobic exercise for 12 weeks effected the blood leptin level in overweight female. Therefore, the concept can be identified that the blood leptin level made in adipose cells effected to decrease of body weight, percent body fat, and fat weight.

마라톤 런너의 장기간 지구력 훈련에 따른 심초음파 변인의 변화 양상

이강우,박호윤 안성산업대학교 2000 論文集 Vol.32 No.-

In that of the structural and functional changes of the heart size is a positive feedback result from diverse training, this study examined the heart size of marathon runners to ascertain the effects of endurance training by m-mode echocardiography. The sample consists of 7 male marathon runners and 6 non-athletes who were not participating in any athletic program, and rest echocardiography was used to measure left ventricular variables. The results ould be drawn as follows: There are significant differences in left ventricular internal end-diastolic diameter(LVIDd), post wall thickness(PWT), septal wall thickness(SWT), left ventricular end-diastolic volume(LVEDV), stroke volume(SV), and left ventricular mass(LVM) between athletes group and sedentary group, but not in left ventricular internal end-systolic diameter(LVIDs) and left ventricular end-systolic volume(LVEDV). In general, previous studies indicated that left ventricular volumic hypertrophy is caused by long-term intense endurance training, and the hypertrophy of left ventricular posterior wall thickness, in contrast, is caused by intense power training. However, long-term intense endurance training can cause the hypertrophy of left ventricular posterior wall thickness in a degree. As a result, he increase in the values of cardiac variables means the change of heart size, and this structural and functional adaptations of the heart suggest that the long-term effect of endurance training is positive feedback.
