Purpose: This study investigated whether there is a correspondence between linear and non-linear analysis for postural stability. Specifically, the focus on this study was to examine whether standard deviation could represent postural stability of whole body and each foot. Methods: 12 young adults participated in the experiment and had to maintain their balance with eyes open in 5 postures: side-by-side (SS), staggered (left (SL) or right (SR) foot forward), and tandem (left (TL) or right (TR) foot forward). Each subject had two 65s trials in each condition. Under two force platform protocol, center of pressure of left (COPL) and right (COPR) was measured and total body center of pressure (COPNET) was finally measured in both the anterior-posterior (AP) and medio-lateral (ML) direction. Standard deviation (SD) of linear analysis and the largest Lyapunov expoenent (LyE) of non-linear analysis were measured for COPL, COPR, and COPNET across whole standing conditions. Results: SD of COPNET was larger in AP than ML in SR and SL conditions, whereas LyE of COPNET in AP and ML were not significantly different. In addition, SD of COPNET in AP was not significantly different from that in ML in TR and TL conditions, while LyE of COPNET in ML was larger than that in AP. Lastly, SD of COPL and COPR in ML was larger than that of COPR and COPL in TR and TL condition, respectively, on the other hand, there was no difference in LyE between COPL and COPR in ML in those conditions. Conclusion: Overall, there is an inconsistency between the SD and LyE during postural dynamics. The findings support the position that SD is not a representative measure of postural stability.

Purpose: The purpose of the study is to identify structural relationship among exercise imagery, physical activity, and health-related quality of life of adults. Methods: Five hundred questionnaires were initially distributed to college students, company employees and sports center members(male: 273, female: 194, Mage=39.21). Among them, total 467 were finally used in this study. Exercise imagery scale, weekly leisure-time exercise questionnaire and short-form health survey-36 were revised into Korean and applied in the study. Frequency analysis, correlation analysis, and structural equation modeling were carried out to test the possible relationship among exercise imagery, physical activity, and health-related quality of life. All analyses were conducted by SPSS 18.0 and AMOS 18. Results: Results indicated that there were positive relationship among exercise imagery, physical activity, and health-related quality of life of adults. In specific, exercise imagery and physical activity had significant positive relationship with vitality which was sub-factor of psychological health-related quality of life. Additionally, exercise imagery was significant factor to physical health-related quality and physical activity. The finding ultimately revealed that a hypothesized research model showed the significant model fit after modification. But it was showed the difference with sex. Conclusion: This study suggests that cognitive intervention strategies aimed at exercise imagery could be significant to promote physical activity and its related health-related quality of life. As it was existed the difference with sex, there will be necessary another studies which is concerned about various variables.

Purpose: The present study examined how self-efficacy and parental support (autonomy and controlling support) mediate and moderate between exercise intention and exercise behavior in children. Methods: Mediation, Moderation, and Conditional process analysis was used with 252 children. Results: The results indicated that the positive association between intention and behavior partially mediated by self-efficacy, and this indirect link was stronger for students with low autonomy and controlling support than for those with high autonomy and controlling support. In addition, both autonomy and controlling support moderated the relationship between intention and self-efficacy. Autonomy support moderated the relationship between self-efficacy and behavior but not the relationship between intention and behavior. On the contrary, controlling support moderated the relationship between the relationship between intention and behavior but not the relationship between self-efficacy and behavior. Conclusion: These findings suggest that intention is positively link to behavior in children’s exercise settings, and self-efficacy and parental supports are key mechanisms in the relationship.

Purpose: The purpose of this study was to investigate the mediating roles of emotions in the relationship between mindfulness and mental health among dance students. Methods: Participants were 683 university dance students (73 males, 610 females). One-way MANOVA, structural equation modeling, and multi group analysis were conducted for the data. Results: Results of MANOVA showed that there was no differences in the level of mindfulness across dance types, but students with high in dance career was higher in attention and acceptance traits than those with low career. The results of structural equation modeling indicated that the fit of the alternative model influencing mindfulness on students`` mental health through emotions was more adequate than a theoretical model. That is, dance students`` positive and negative emotions partially mediated the relationship between mindfulness and mental health. The results of multi-group analysis showed that each of the direct effects in the model was invariant across dance careers. Conclusion: These findings imply that dance students`` abilities being aware of experiences at present, orienting its acceptable attitude, and regulating their attention are important to enhance their mental health, especially decreasing the impact of negative experiences on it.

Purpose: of this study was to investigate the effects of emotional intelligence and perceived coaching on burnout for korean, chinese swimming athletes. Methods: emotional intelligence, perceived coaching behaviour, burnout questionnaire was asked 97 korean, 88 chinese swimming athletes. we conducted the exploratory factor analysis and Cronbach α Analysis to found out construct validity and reliability. independe t-test used for difference between korea and china. quartile split used for turning the continuous variable, emotional intelligence and perceived coaching behaviour, into a 3 categorical levels and the data were analyzed using ANOVA. finally we conducted regression analysis. Results: first, korean swimming athletes showed more higher burnout than chinese. but chinese swimming athletes showed more higher emotional intelligece and perceived coaching behavior than korean. second, burnout was significantly different according to the level of perceived coaching behavior. third, burnout was influenced by perceived coaching behavior. Conclusions: findings suggest that the difference of variables with their cultural backgrounds will contribute to the cross-cultural study. Finally we discussed cross cultural psychology on that results and proposed athletes’ burnout.

Purpose: The present study examined whether golf mindfulness routine (GMR) enhances golf performance (objective and subjective), taking into consideration the effects of dispositional mindfulness. Methods: Five male high-level golfers participated in the study. Basic procedures of GMR were consisted with three phases: a) awareness of environmental conditions, b) focusing on body-mind conditions c) monitoring and accepting emotions in present. A single-subject design (changing conditions design) was used to determine the effects of GMR over three sessions (pre, post, follow up). Results: The results were provided for the effectiveness of GMR on golf performance in all golfers. GMR also fostered dispositional mindfulness of golfers over intervention sessions. Conclusion: The theoretical significance of the results is assessed and the application of GMR in golf performance enhancement is discussed.

Purpose: The purpose of this study was to prove the influence of method biases of social desirability on the sequential process of basic psychological needs → motivation → flow and emotion, suggested in HMIEM. Methods: This study conducted a questionnaire survey with 307 high school athletes. Structural Equation Model was employed to look into the scale of common method biases induced by social desirability. Results: As a result, a, b, and c, each of which is factor loading prior to control of social desirability, were .76, .80, and -.31, as shown in figure 2. Each factor loading after control of social desirability (shown in table 2) fell to .43, .56, and -.18. With regard to the SMC of each latent variable prior to control, the SMC of motivation was 57.5%, that of flow 63.5%, and that of emotion 9.8%. However, after control, motivation``s SMC remarkably fell to 18.5%, flow``s to 31.2%, and emotion``s to 3.2%. Conclusion: Therefore, social desirability, one of common method biases, influenced the research model.

Purpose: This study aims to predict college students’ physical activity based on a hypothetically integrated model of stages of change for physical activity and theory of planned behavior. Methods: A total of 302 college students (male: 70.2%; female: 29.8%; Meanage= 23.6 years old) participated in the survey. Attitude scale, the subjective norm scale, perceived behavioral control scale, stages of change scale and physical activity scale were used. Results: As a result of a path analysis, in the TPB constructs, perceived behavioral control had a statistically significant impact on the stages of change for physical activity (.34). In addition, perceived behavioral control had direct impacts on physical activity (.44). The stages of change for physical activity had an impact on physical activity (.23) Conclusion: The results of this study suggest a possibility of a theoretical integrated study on psychological variables with college students. The current study points out that further studies should be carried out to verify the effectiveness of the integrated model to explain physical activity.
