The purpose of this study was to investigate the effects of circulation exercise on health related fitness and metabolic syndrome risk factors obese in middle age women. Twenty, obese middle age women($BMI<25kg/m^2$) composed of circulation exercise group(EX, n=10), the control group(CON, n=10). The variables of health related fitness, metabolic syndrome risk factors were measured in all the subjects before the start and after the end of 12 week circulation exercise program(60~80 %HRR, 3 times per week, 30~40 mins). The test data were analyzed by paired t-test and repeated ANOVA, and the alpha level of p<.05 was set for all tests of significance. Health related fitness and metabolic syndrome risk factors were measured pre and 12 weeks of post exercise training. %body fat(p <.01) was significantly decreased in EX group compared to CON group. LBM(p <.05), muscular endurance(p <.05), flexibility(p <.05) and cardiorespiratory endurance(p <.001) were significantly increased in EX group compared to CON group. WC(p <.05), SBP(p <.01), DBP(p <.05), Glucose(p <.05) and TG(p <.05) were significantly decreased in EX group compared to CON group. HDL-C(p <.01) was significantly increased in EX group compared to CON group. These results suggest that 12 weeks of circulation exercise training improves health related fitness and metabolic syndrome risk factors. Thus, this newly proposed circulation exercise modality can be a useful therapy to improve both health related fitness and metabolic syndrome risk factors in obese middle age women.

This study was to investigate the effects of aquarobics exercise on body composition, fitness and health related quality of life (sf-36) in elderly women and to provide basic data to exercise prescription. The subjects were the 60~70 years old seniors who participated in exercise program at health promotion center and had been divided into exercise(N=25) and control(N=30) group, respectively. Aquarobics exercise was performed twice per week for 8 weeks at 40~70% heart rate reserve(exercise intensity) and body composition, fitness and SF-36 were measured before and after exercise. In body composition, there were significance in weight(p=0.044), body mass index(p=0.038), and %fat(p=0.005) between groups before and after. In fitness, there were no significance in fitness such as chair stand, and chair sit and reach, but there were significance in 2-minute step(p<0.001), arm curl(p=0.005), back scratch(p=0.023), and 8-ft up and go(p<0.001) between groups. In SF-36, there were no significance in physical functioning, role limitation-physical, role limitation-emotional, social functioning, mental health, and vitality, but there were significance in bodily pain(p=0.039), and general health(p=0.024) between groups. It was found that aquarobics exercise was one of the good exercise types for the elderly to improve body composition and fitness. Also, there was positive effect on health-related quality of life partially.

We investigate the evolutionary dynamics and the phase transitions of the island model which consists of subdivided populations of individuals confined to two islands. In the island model, the population is subdivided so that migration acts to determine the evolutionary dynamics along with selection and genetic drift. The individuals are assumed to be haploid and to be one of two species, X or Y. They reproduce according to their fitness values, die at random, and migrate between the islands. The evolutionary dynamics of an individual based model is formulated in terms of a master equation and is approximated by using the diffusion method as the multidimensional Fokker-Planck equation (FPE) and the coupled non-linear stochastic differential equations (SDEs) with multiplicative noise. We analyze the infinite population limit to find the phase transitions from the monomorphic state of one type to the polymorphic state to the monomorphic state of the other type as we vary the ratio of the fitness values in two islands and complete the phase diagram of our island model.

The purpose of this study is to analyze the problems of the Physical Activity Promotion System(PAPS) implemented in elementary, middle, and high schools in Korea and to prepare improvement measures. The data of the study was obtained through in-depth interviews, related papers, and press releases. The research participants of this study were 5 incumbent physical education teachers who directly instruct and measure PAPS at school and 5 college students who directly experienced PAPS. The results of the study are as follows. First, the problems that occurred in the educational environment of PAPS were students' indifference, teachers' passive guidance, and decreased physical education hours replaced by PAPS measurement days. Second, the problems occurring in the measurement environment of PAPS were errors due to measurement equipment, deviations due to different measurement locations, and differences in grades according to measurement items. Third, the problems that occur in the measurement process of PAPS are the lack of measurement personnel, the expedient physical fitness measurement, and the non-standardized measurement method. In order to improve these problems and successfully apply PAPS, the following improvement measures should be attempted. Details on this are as follows. First, teachers should inspire students' interest and interest in PAPS. Second, it is necessary to secure the reliability of the measurement result value of PAPS. Third, it is necessary to systematically supplement the school education system for PAPS measurement.

With the development of tangible interface in recent years, the interest in interactive exercise games to improve health-related physical fitness has been increased. We believe that this kind of serious game should provide not only motion sensing of the action required to play sports but also a specific effectiveness of exercise. This paper will show how a serious exercise game affects theirs heart rate and preference. For the experiments, we used an exercise game named GalaxyBike for aerobics exercise which is developed by the Interaction Media Research Center of Hoseo University. In the experiments, players' heart rate was measured during the warming-up, exercise and cooling-down periods by a wireless heart-rate measuring instrument. After they played the exercise game, a survey was conducted to see how they like this serious exercise game. The findings of the study suggest that the serious exercise game providing both video game and exercise would make a contribution to the improvement of health-related physical fitness since it serves to increase the heart rate and motivation.

This study analyzed in depth the students' health fitness trend characteristics based on the per generation characteristics longitudinal grade level document that was produced by collecting heath fitness measurements of students from all over the country for the purpose of exploring the appropriate wellness management plan. The following conclusion was derived through the collected materials and results according to the research purpose and method. First, it was determined that muscular endurance trends for both boys and girls in their elementary school period were similar for the current generation and the previous one, but as they went through their middle school period their muscular endurance development levels were found to be reduced compared with the previous generation students. Second, there was no difference in the cardiorespiratory endurance trends between the current and the previous generation students, unlike all other physical factors. Third, the boys displayed deteriorated reflex development during their growth period compared with their previous generation counterparts. On the other hand, girls displayed mostly stagnant development once they reached 8th grade level within their generation.
