Purpose The current study investigated the effects of exercise information using social network service(SNS) to identify changes of physical activity and psychological variables among inactive college students. Methods Inactive college students(30 experimental group, 30 control group) were voluntarily participated in the 12-weeks intervention. During this period, the experimental group received exercise information through SNS. And all study participants’ physical activity, stages of physical activity, self-efficacy, motivation, and perceived benefits and barriers were measured at the pre, mid and post intervention. Frequency analysis, chi-square test, 2-way ANOVA RM were conducted to analyze data obtained in the study. All procedures were performed by using SPSS 23.0. Results The exercise information intervention using SNS during 12 weeks had a positive effect on the stages of physical activity of inactive college students, and there were statistically significant differences. In addition, physical activity, perceived benefits and barriers, self-efficacy, motivation positively improved after the intervention, but there were no statistically significant differences between experimental and control group. Conclusions The present study suggests that psychological strategies using various SNS programs have positive effects for inactive college students to increase physical activity and its related psychological variables.
Purpose The purpose of this study was to investigate the effects of regular vigorous- and moderate-intensity aerobic exercise on serum brain-derived neurotrophic factor (BDNF) level, aging- and lifestyle disease-related blood components in middle-aged women. Methods The participants were recruited from a total of 19 physically healthy people aged 50-59 years, and were randomly divided into vigorous-intensity aerobic exercise (VIAE, n = 10) and moderate-intensity aerobic exercise (MIAE, n = 9) group. The participants were performed vigorous- and moderate-intensity aerobic exercise three times a week for eight weeks, and body composition measurement, graded exercise test, blood collection were performed before and after. Results Mean exercise time was significantly longer in the MIAE group than in the VIAE group. The V̇O2max was significantly higher in the VIAE group than in the MIAE group. Body weight, BMI, and body fat percentage were significantly lower than pre both groups. The BDNF concentration was significantly higher in the VIAE group than in the MIAE group. The dehydroepiandrosterone sulfate (DHEA-s) and insulin-like growth factor-1 (IGF-1) concentration were significantly higher than pre both groups. The free fatty acid and triglyceride concentrations were significantly lower than pre both groups, and HDL-C concentrations were significantly higher than pre both groups. Conclusions Vigorous-intensity aerobic exercise not only increases maximal oxygen uptake and blood BDNF level in middle-aged women, but also induces positive changes in aging-related hormones and lifestyle-related blood variables.

Purpose The purpose of this study was to understand learning experiences deeply and to prepare practical teaching strategies by reflecting the voices of the field. Methods For this, I used the logic and techniques of 'the grounded theory'. In particular, I used ‘the grounded theory paradigm model', which enables a holistic and systematic analysis of specific experiences to explore learning experiences and teaching strategies. I selected 10 male and female students who participated in art and physical activities as research participants. I collected data through literature review, in-depth interviews, and expert meetings, and analyzed using open coding, axial coding, and selective coding. Results First, I explored “the learning experience of art and physical activities in free-semester system", according to the elements of grounded theory paradigm model. It is composed of the ’causal condition’, ‘contextual condition’, ‘central phenomenon’, ‘interventional condition’, ‘interaction strategy’, and ‘results’. Second, based on this, I conducted "the teaching strategies for art and physical activities in free-semester system". These are composed of 'expansion strategy', 'diversity strategy', 'spontaneity strategy', and 'immersion strategy'. Conclusions The results of this study suggest that art and physical activities in free-semester system are leading to a positive change extended from the planned goals. In addition, various variables are structurally intertwined, and thus, it is considered that more strategic and systematic efforts are required in various dimensions for the successful application.

[Purpose] This study attempted to provide a literature review of the research on posttraumatic growth and to propose a revised model which mainly explain the relationships among serious leisure, posttraumatic growth, health, and happiness. The concept of psychological growth following a traumatic life event is most commonly referred to as posttraumatic growth in the literature and was first coined by Tedeschi and Calhoun (1995). It can be postulated that such experiences can lead to a richer appreciation for life, more compassion for others, closer relationships with others, better understanding of one's potentials and possibilities, and stronger religious faith. [Methods] The purposes of this study were achieved by (1) reviewing the posttraumatic growth and its relationship to serious leisure; (2) analyzing recent posttraumatic growth related models; and (3) proposing a revised posttraumatic growth model and a research agenda to further progress posttraumatic growth research. [Conclusions] Although there is an abundance of evidence for the existence of posttraumatic growth, its nature as well as benefits in relation to participation in serious leisure remain very partially understood. This study proposes a revised model for understanding the process of porsttraumatic growth in which serious leisure and cognitive processing play a significant role. Important implications of the relationships between serious leisure and posttraumatic growth are mainly discussed, alongside recommendations for future research.
[Purpose] The purpose of this study was to examine the differences in visual search strategies between expert and novice badminton players while performing badminton serve. [Method] To this end, expert (more than 10 years experience) and novice (less than 6 months experience) badminton players performed 15 trials of two types of serve (i.e., short-serve and long-serve), in total 30 trials. All the participants’ eye movement was recorded during each trial, and mean fixation duration, fixation distribution, final fixation duration and location, and gaze entropy were analyzed. [Results] The results showed that there was no difference in mean fixation duration between expert and novice players. The analysis of mean fixation duration on each location showed that participants fixated more on the net while doing short serve whereas fixated more on the space when they did long serve. In particular, expert players fixated more on the space while doing long serve than novice players, and fixated more on the net and racquet for the short serve. However, novice players fixated more on the location of shuttle would be landed. The final fixation duration was not different between expert and novice players. Further, expert players showed higher gaze entropy than novice players. [Conclusion] The findings indicate that expert players fixated more on the net for the short serve, and the space for the long serve, and visual search strategies of experts were more varied than novice players.
