This study was aimed to determine the effects of cryotherapy on lactate acid accumulation following muscle fatigue-inducing concentric exercise of the knee. Eight healthy mans performed a bout of concentric exercise which is composed of three sets of one-hundred fifty maximal reciprocal contraction at 30° /sec. on isokinetic dynarnoneter, Subjects were immersed their exercised leg in cold water at 10℃ and 15℃ for 30min immediately after concentric exercise and then rested in ambient condition lasting 6hours. Also, subjects were participated in controlled condition which was rested in ambient condition during the same period. Lactate acid was measured at resting before muscle fatigue, immediately, 3min, 5min, 10min, 20min 30min, 2hours, 4hours and 6hours after concentric exercising. The data of measurement was analyzed by using SPSS-PC Windows program. To analyze the difference among three conditions used General Repeated Measure ANOVA. Based on the findings of the study, the following conclusion has been derived: There was significant between controlled and cold water immersion condition and time of measurement for lactate acid concentration(p<.05). However, there was no significant between 10℃ and 15℃ cold water immersion condition for lactate acid concentration. Exercise-induced lactate acid of muscle tissue diffuses into blood flow which increase to exercise muscle. Therefore there is a positive effect for rapid recovery of lactate acid because the decreased logic body temperature by cold water immersion result in enhanced blood flow and reduced metabolism ratio It seems to be appeared that the cold water immersion has positive effect to recovery of muscle fatigue after strenuous concentric contraction of leg. Although the statistical significant from this study exists in the concentration of lactate acid, the results also show that other variables of fatigue have been reduced after application of cryotherapy. In conclusion, it appears that the cryotherapy might be a helper of the recovery of fatigue after strenuous exercise than non-treatment.

This study was intended to make a comparative analysis of golfing athletes's stress factors. For this purpose, 200 male and female golfing athletes on the Korea Golf Association was selected as the subjects of this study. They were made up of 151 student athletes and 49 general(professional) athletes, the former of whom were composed of 75 college athletes and 76 high school golfing athletes. The research instrument was the questionnaire composed based on the study on athletes' preventive management conducted by Lee Kye-yun et alOggl), which totalled 45 items. They was investigated using the 5-point Likert rating scale. Collected data were analyzed using SPSS - PC 80. Here, the analysis of variance and the significant inter-group post-test were conducted using the Bonferoni method. And the t-test was conducted. As a result, the following conclusion was drawn: First, this study drew 9 stress factors from golfing g athletes: (1) game factor, (2) athletics factor, (3) extra-exercise factor, (4) decision-making factor, (5) expectation factor from familiar people, (6) team cohesion factor, (7) training factor college students, (8) competition anxiety factor, and (9) home factor. Second, an attempt was made to compare 9 drawn factors by dividing subjects into the group of general(professional) athletes, the group of college students, and the group of high school athletes. As a result, it was found that there was a significant difference on such factors as game, extra-exercise handicap, decision-making, expectation from familiar people, competition anxiety and home among groups. Third, an attempt was made to analyze the difference on each factor among groups. As a consequence, the following findings were obtained: 1) It was found that there was a significant difference on the extra-exercise handicap factor between groups of general(professional) athletes and college athletes and between general(professional) athletes and high school athletes. 2) It was found that there was a significant difference on the decision-making factor between the groups of general(professional) athletes and high school athletes, which is thought to be sue to a sense of expectation toward the future. 3) It was found that there was a significant difference on such factors as expectation from familiar people and home between the groups of general(professional) athletes and high school athletes. 4) It was found that there was a significant difference on the competition anxiety factor between the groups of college athletes and high school athletes. Judged from the above factor analysis, it is thought that such factors as anxiety about the future, anxiety about expectation from familiar people and impatient mentality exerted an effect on both the groups of general athletes and high school athletes. Fourth, it was found that there was a significant difference on such factors as game, team cohesion and competition anxiety between male and female golfing athletes.

The purpose of this reserch was to oxygen consumption (VO₂), respiratory exchange ratio (RER), heart rate (HR) energy expenditure and excess post-exercise oxygen cosumption(EPOC) of gymnast of elementary school and those of general student of elementary school during 60 minutesafter maximal exercise. Ten gymnasts and the other ten general students participated in the experiment and measured variables before, during and after the exercise. I measured it for 60 minutes after the exercise. Oxygen uptakes when they take a rest is not to eat over 10 hours and arrive at laboratory about 6 o' clock in the morning. And after the arrival at laboratory they lay for 20 minutes to take a rest. I measured EPOC from oxygen uptakes in recovery reduced oxygen uptakes in the rest. According to result of Two-way repeated measures ANOVA and Bonferroni, oxygen intake recovery was not higher(p>.05). But oxygen uptake of gymnasts were significantly higher than those of general students during rest period and post-exercise recovery period. HR of general students was significantly higher than that of gymnasts(p<.05) and rest period between post-exercise recovery period stages were significantly higher(p<.05). RER of gymnastic group was higher than that of general students during recovery period was rest also rest period between post-exercise recovery period was significantly higher(p<.05). After exercise, those of gymnasts(365.68㎖/㎏/min) and general students (365.5㎖/㎏/min) were not higher during 60 minutes of EPOC but it was higer in interval. General students was significantly higher(90.79kcal) that energy expenditure during exercise. Results of this research can be important index for preparing appropriate sports program to prevent fatness by measuring VO₂, RER, HR and EPOC after maximal exercise of children. And I hope that these results can be used for training to modulate weight of gymnasts.

It had been proved theoretically in this study that leisure constraint as perceived by housewives is major psychological barrier to leisure satisfaction and leisure satisfaction is the one and only variable predicting family cohesion and life satisfaction. The subjects of this study were 754 housewives who are 25 years old and over, living in Seoul metropolitan area. Subjects were selected by the strafied random sampling in order to meet the characteristics of subject samples those who are either actively or passively engaged in leisure activities. Research instruments were devised by the researcher herself, pretested, and proved that contain content validity and reliability. They were Crawford et al’s item Leisure Constraint Scale, Ragheb and Beard’s LSS(Leisure Satisfaction Scale) background variables that the research herself developed. The major findings of this study were that the most significant factors affecting the degree of life satisfaction of the middle class Korean housewives were family cohesion, leisure satisfaction and perceived leisure constraint. It was also found that the degree of family cohesion could be amelioliated by the leisure satisfaction that influenced by participant’s socioeconomic variables such as income and educational backgrounds. According to the analysis, we conclude the following: 1. Their effort of accomplishments can be affected on their satisfying lives. 2. As long as there is a higher level of education, they satisfy their lives in a great amount. 3. Since the education level can affect the family togetherness positively, it can be affected well by the housewife’s higher education level.
