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.

In general polyester is extremely used to increase the ratoi of the warmth heat resistance among quilting products as a padding, make polyester the object of this study and examine the thickness in terms of quilting type, air volume, air permeability, quilting interval, the ratio of the warmth heat resistance followed by the variation of no-flow, and flow case or after-washing and before-washing. In brief, the result is as follows; 1. In all quilting type, Clo value is found on increasing tendency with increase of thickness. And in non quilting samples, the more porosity grows up the more Clo value decreased. 2. In each quilting type comes in evidence a similar air permeability and it doesn't have an interrelationship with Clo value. 3. In each quilting type with much air volume. Clo value increases;in the same quilting type the more quilting interval increases the Clo value increases. 4. In each quilting type, Clo value is discovered an increasing tendency by 7.5cm;it is not discovered an increasing tendency above the ratio. But in flow case, Clo value doesn't change at all by 200cm/sec as in no-flow case and it is discovered a decreasing tendency above the ratio. 5. In flow case and no-flow case, the variation of the Clo value followed by the quilting type is identical. And Clo value increases in checker<spiral<righted-spiral<vertica quilting type by turns. 6. Clo value after-washing with quilting samples if sound a little more increased tendency than Clo value before-washing samples.
