The purpose of this study was to investigate the effects of detraining and retraining on serum lipid and hormones in soccer players. Subjects were seven male high-school soccer players. V˙O_2max was determined for each subjects by administering a treadmill test(initial speed: 90m/min, grade: 5%, increasing speed per 3 min: 30m/min). Serum lipid(T-C, TG, HDL-C LDL-C) and hormones(epinephrine, norepinephrine, growth hormones, cortisol) were assayed pre and post detraining in 10, 20, 30 days after retraining. The repeated ANOVA was used to determine significant differences. The 0.05 level of significance was as critical level for the study. The results of the study were as follows: 1. V˙O_2max(ml/min) were 3576.3±204.2ml/min pre detraining, 3234.1±198.9 ml/min post detraining. There are significant(p<.05) difference between pre and post detraining. In 10, 20, 30 days after retraining, V˙O_2max(ml/min) were 3601.4±170.9 ml/min. There were significantly(p<.05) increased in retraining periods. 2. V˙O_2max(ml/kg/min) were significantly(p<.05) decreased from 62.3±2.9 ml/kg/min to 55.9±4.7 ml/kg/min in detraining. In 10, 20, 30 days after retraining, V˙O_2max(ml/kg/min) were 62.4±3.4ml/kg/min, 62.7±2.3ml.kg/min, 67.3±7.2ml/kg/min respectively. There were significantly(p<.05) increased in retraining periods. 3. T-C were significantly (p<.05) increased from 166.6±8.5mg/dl to 175.3±10.3 mg/dl in detraining. In 10, 20, 30 days after retraining, T-C were 160.1± 3.2mg/dl, 156.7±3.7mg/dl, 140.3±9.0mg/dl. There were significantly(p<.05) decreased in retraining periods. 4. HDL-C were 61.4±6.6mg/di pre detraining, 5.3±6.6mg/dl post detraining. There are significant(p<.05) difference between pre and post detraining. In 10, 20, 30 days after retraining, HDL-C were 56.9±7.1mg/dl, 56.4±9.2mg/dl, 57.7±9.1mg/dl respectively. There were no significant difference in retraining periods. 5. The hormones(epinephrine. norepinephrine, growth hormone, cortisol) were changed as same patterns. Epinephrine were 26.0±7.0[g/ml pre detraining, 24.6±3.2pg/ml post detraining. In 10, 20, 30 days after retraining, epinephrine were 26.9±5.6pg/ml, 30.6±6.2pg/ml, 29.4±5.6pg/ml respectively. There were no significant difference in retraining periods. In conclusion, HDL-C, epinephrine, norepinephrine, growth hormone and cortisol were decreased, T-C, LDL-C and TG were increased in detraining. But HDL-C, epinephrine, norepinephrine, growth hormone and cortisol were increased, T-C, LDL-C and TG were decreased in retraining.

본 연구는 스트레스 반응을 측정하는 스트레스 반응 척도 설문지(Symptoms of Stress: SOS)를 이용한 횡단적 연구로서 심신수련의 하나인 기수련이 스트레스 반응에 미치는 효과를 살펴보았다. 72명의 건강한 정상인과 180명의 기수련자를 대상으로 하여 조사하였으며, 기수련자들은 수련기간에 따라 초급군(1-4개월; 64명), 중급군(5-12개월; 50명), 고급군(1년 이상; 66명)로 나누었다. 실험결과 1년 이상 수련한 기수련자들이 말초혈관 증상군, 심폐 증상군, 중추신경계 증상군, 위장계증상군, 습관적 행동 형태군, 우울 증상군, 불안증상군등의 스트레스 반응 하위척도에서 대조군에 비해 통계적으로 유의하게 감소하였다. 전체 스트레스 값은 대조군에 비해 기수련자 집단이 아주 낮았으며 수련기간이 길수록 감소하였다. 이러한 결과는 기수련이 스트레스 중재와 스트레스 증상을 줄이는데 효과가 있음을 나타낸다. We examined the effects of Qi-training, one of Korean traditional psychosomatic training, on stress coping ability by cross-sectional investigation with inventory of symptoms of stress (SOS). Four types of groups- normal healthy (n-74), three groups of Qi-trainees (group primary level: subjects with Qi-training for 1-4months, n=64; middle level: 5-12 months, n=50; high level: more than 12 months, n=66) participated in this study, Qi-trainees with over 1 year training had significantly lower scores in all SOS subscales compared to controls. Total stress scores of Qi-trainee groups were substantially lower than controls and further reduction with larger training periods. These results suggest Qi-training is effective in stress management and decreasing symptoms of stress

In this paper, we have proposed an effective moving objects tracking method based on the motion information in the video sequence. First, we extract the moving objects using the processes of morphological dilation and differential image in the video sequence and then we extract the motion information utilizing the location and orientation of the moving objects in the subsequent images. The motion information is extracted using various statistical measurements, extracting the high-level features from the regions of pixels in the images. The measurements, such a s area, length, perimeter, orientation, elongation, compactness, moments of inertia, are used as the statistical and geometrical descriptors. The principle axes of an object on this features gives the local direction of the object, while the center of gravity gives the center position of the object. The angle between two principal axes of the moving objects in the consecutive images gives the geometrical direction of the moving object, while the displacement of the center of gravity, gives the distance covered by the moving objects. So we have extracted the global motion information using the principal axes and center of gravity. The simulation results on the test images are very good, where either the motion is very slow, or the frame rate is very high.
