An Analysis of the Relationship between Sports Center Users' Participation in Physical Activity, Leisure Boredom and Leisure Satisfaction The purpose of this study is to research and analyze the relationship between sports center users' participation in physical activity, leisure boredom and leisure satisfaction. To be more specific, this study examined the effect of level of participation in physical activity - participation frequency, participation intensity and participation duration - on leisure boredom and leisure satisfaction. I used simple random sampling to pick out 312 physical program participants from a population composed of five sports centers in Seoul, Korea in 2003. It is conducted using the Questionnaire on the Relationship between Sports Center Users Participation in Physical Activity, Leisure Boredom and Leisure Satisfaction. The Cronbach's α method gave a subordinate factor-based reliability coefficient of α = .6921 for leisure boredom and α = .9385 (highly reliable) for leisure satisfaction, respectively. The methods for data analysis used for this study include frequency analysis, correlation analysis and regression analysis. Study findings are as follows: 1) As for the participation frequency relating to the level of participation, the effect have a positive correlation with participation intensity(r=.162*), participation duration(r=.147*) and leisure satisfaction(r=.275*) while the effect on participation intensity have a positive correlation with leisure satisfaction(r=.151*). 2) A statistically insignificant difference (5% range) was identified regarding all subordinate factors (i.e., participation frequency(β=.093), participation intensity (β=.075), participation duration(β=.032) 3) A statistically significant difference (5% range) was identified regarding all subordinate factors (i.e., participation frequency(β=.231), participation duration(β=.185)) while a statistically insignificant difference was identified for participation intensity(β=.107). Participation frequency and participation duration have a positive correlation of 12.3%(R²=.123) with leisure satisfaction.

The purpose of this study was to investigate the effects of the aerobic exercise and resistance exercise program on the aerobic exercise capacity, ST segment depression and risk condition of cardiovascular disease in the obesity elderly women. Subjects were 10 elderly women, who aged 65~72 years old. Subjects were trained by the aerobic exercise and resistance exercise training program that was composed of the intensity of 40~60% HRmax, the duration of 30~40min, the frequency of 3~4d/w, and period of 12weeks. To analyze measured data, the paired t-test were completed with before and after complex training data. The conclusions of this study were as follows; 1. In aerobic exercise capaclty, after 12 weeks training, percent body fat, were decreased, body fluid were increased. Resting and recovery heart rate(HR) were decreased between before and after training. Resting and peak systolic blood pressure (SBP) were decreased between before and after training. Oxygen uptake(VO2) were increased between before itnd after training. Myocardial oxygen uptake(MVO2) were decreased between before and after training. In ST segment, ST Ievel were increased significantly, ST slope were decreased between before and aftcr training. 2. When ST/HR slope were compared with ST segment, the ischemic symptoms were apt to early diagnose in ST/HR slope. 3. Duke treadmill exercise score(DTS) were increased between before and after training. In conclusion, we could know that not only the regular training might increase or change almost the cardiovascular function variables for body composition, exercise capacity, and ST/HR slope between before and after training. Therefore, we might tell that training program could provide an excellent parameters for enforcing or keeping the cardiovascular function of elderly women

JENB., Vol. 19, No. 1, pp.25-30, 2015 [Purpose] The purpose of thisstudy was to investigate the effects of potato and lotus leaf extract intake on body composition, abdominal fat, and blood lipidconcentration in female university students. [Methods] A total of 19 female university students participated in this 8-week study,and they were randomly assigned into 2 groups; potato and lotus leaf extract (skinny-line) administered group (SKG, n=9) andplacebo group (PG, n= 10). The main results of the present study are presented below. [Results]1) Body mass index, and percentbody fat and abdominal fat in students of the SKG showed a decreasing tendency without significant interaction, 2) total cholesterol(TC), triglyceride (TG), and low density lipoprotein (LDL-C) in students of the SKG showed an averagely decreasing tendencyand there was a significant interaction of TC only, 3) high density lipoprotein (HDL-C) in students of the SKG showed an increasingtendency without significant interaction, and 4) Z-score of fatness testing interaction in group × repetition did not show a significantinteraction; however, there was a significant interaction of TC in group × repetition. Based on these results, 8-week intake ofpotato and lotus leaf extract had a positive effect of lowering TC. On the other hand, it had no significant effect on other typesof lipids and percent body fat changes. [Conclusion] There was a positive tendency of blood lipids in students of the SKG andit seems that potato and lotus leaf extract intake might prevent obesity and improve obesity related syndromes.
