This study sought to explore the online consumption propensity of sports goods by generation of the productive population and to provide basic data to predict the future consumption market by segmenting online consumers in the sports 4.0 market. Therefore, this survey was conducted on those who consumed sports goods among the generation-specific groups (Generation Y and above, Z) of the productive population, and a total of 478 people's data were applied to the final analysis. Data processing was conducted with SPSS statistics (ver.21.0), frequency analysis, exploratory factor analysis, correlation analysis of re-examination reliability, reliability analysis, and decision tree analysis. According to the online consumption propensity of sports goods by generation of the productive population, there is a high probability of being classified as Generation Z group if the factors of leisure, joy, and environment are high. In addition, the classification accuracy of such a model was 69.7%.

The purpose of this study, the wearing conditions of functional pressure clothing applied with the thermotherapy device were determined by three types (NW, CW, TCW) and the difference in isokinetic strength, muscle activity around the forearm was investigated and the effects of products mixed with thermotherapy and pressure treatment were verified. Ten men in their 20s were selected as subjects, and all subjects were randomly assigned three wearing conditions, and wrist flexion/extension exercise was performed at 30° and 90° angular velocity in isokinetic equipment. Peak torque, average power, and EMG were measured during exercise in all conditions. For peak torque, CW was significantly highest at velocity of 30°/sec flexion. Average power showed no significant difference by condition. In the angular velocity of 90°/sec, flexion was significantly higher in CW and TCW than in NW. As a result, wearing clothes with pressure effect and heat effect can show high efficiency in high muscle strength development and fast contraction activity during low speed exercise, and it is thought that it can show improvement of exercise ability through efficient recruitment of motor unit.

The purpose of this study was to examine the effects of 8 weeks of resistance exercise on gait-related abilities and the differences in age groups to provide reference materials for application of training by age group. Subjects in their 30s, 40s, and 50s were recruited and subjected to a lower extremity exercise, in which the intensity gradually increased three times a week for eight weeks. The gait-related variables, torque at 0.18 sec, acceleration time, and torque at 30°, were assessed through isokinetic tests before and after the 8-week training. The torque at 0.18 sec showed a significant increase in the 50s group. There was no significant difference in acceleration time according to time and group. The torque at 30° showed a significant increase in the 30s group. In conclusion, 8 weeks resistance training can increase neuromuscular activity in adults in their 50s group, and changes in training variables are needed to increase torque at 30° that affects knee stabilization in adults over 40s group.

The 5 day workweek has become widespread, and more recently, the 40 hour workweek is planned to be implemented to the Korean industry by the government by 2012. It is possible that in the future, we may begin to complain about too much leisure, rather than too much work. There is a need then, for types options in leisure activity, brought about by personal choices and interests. The use of leisure time is a very personal matter. It is deeply related to types with the quality of life. Bagozzi (1981) developed a model discerning among attitude, intention and activity, that attitude affects behavioral intention, and behavioral intention affects activity. So, as behavioral activity has a deep relationship to behavioral intention, participation intention according to leisure types leads to participation in leisure activity. Sports activity and hobby and cultural activity appear to have high participation and it seems that this is reflected in behavioral attitude. Among the types of leisure satisfaction, sport activity satisfaction is associated with a more positive attitude to leisure than other types. With respect to background variables for attitude toward leisure according to leisure satisfaction, the biggest differences in attitude toward leisure were associated with sports activity.

The purpose of this study is to examine gender equity in the quantity and flow experience of leisure time of urban dual-earner couples having preschool children. The quantity of leisure time is measured by primary activity and the flow experience of leisure time is measured by primary and secondary activities. The data collected by Korean National Statistical Office in 2004 is used. The sample for this study consists of 255 couples, and the statistical methods are frequency, percentage, paired t-test, and one-way ANOVA. The following is a summary of the major findings. The first, the pattern of the leisure time was different between husbands and wives. The quantity of leisure time of husbands was longer than that of wives. The husbands spent more time to perform social activities, media contact, sports and outdoor activities, while women did more in religious activities. The second, husband's leisure flow experience was higher than that of wives. The pure leisure time of wives was shorter than that of husbands and wives experienced more contaminated leisure time by a secondary activity. In other words, wives's leisure is more likely to be interrupted, to involve episodes of shorter duration, and to be associated with personal care and unpaid work.
