Objectives: The purpose of this study was to analyze factors affecting school life adjustment of athletes in middle and high school. Methods: The data in this study came from the survey which conducted to 500 students of physical education high school athletes and elite athletes in general school from the beginning of December 2009 to the end of January 2010 in Seoul and Kyunggi. Finally 436 cases was used. The dependant variable in this study was school life adjustment. And the independent variables were socio-demographic factors, stress and depression factors, social support factors. The analysis methods were T-test, ANOVA, correlation analysis, stepwise multiple regression analysis by using SPSS Ver. 12.0. Results: First, there was a statistically significant result between school life adaptation and sex, family circumstances, life satisfaction variables Second, there was a negative correlation between social support and stress, depression. Third, there was a negative correlation between school life adjustment and some stress factors, all depression factors. Also relationship between school life adjustment and social support showed a positive correlation. Fourth, Taking a look at the impact on school life adjustment, family factors and practical environmental factors in the stress factors and the feeling of worthlessness in the depression factors appeared to influence negatively. Also teachers' support in the social support factors showed positive effects. Explanatory power of the final regression model was 25.6%. Conclusions: The first step in order to improve the school life adjustment of athletes in middle and high school is the teachers' support. Athletes in middle and high school can have capability, responsibility, initiatives through teachers' attention and affection. The effective prevention education and health education programs on stress and depression should be introduced and carried out in the health education programs actively for student athletes to be free from stress, depression.

BACKGROUND/OBJECTIVES: The purpose of this study was to assess the accuracy of a dietary reference intake (DRI) predictive equation for estimated energy requirements (EER) in female college tennis athletes and non-athlete students using doubly labeled water (DLW) as a reference method. MATERIALS/METHODS: Fifteen female college students, including eight tennis athletes and seven non-athlete subjects (aged between 19 to 24 years), were involved in the study. Subjects' total energy expenditure (TEE) was measured by the DLW method, and EER were calculated using the DRI predictive equation. The accuracy of this equation was assessed by comparing the EER calculated using the DRI predictive equation ($EER_{DRI}$) and TEE measured by the DLW method ($TEE_{DLW}$) based on calculation of percentage difference mean and percentage of accurate prediction. The agreement between the two methods was assessed by the Bland-Altman method. RESULTS: The percentage difference mean between the methods was -1.1% in athletes and 1.8% in non-athlete subjects, whereas the percentage of accurate prediction was 37.5% and 85.7%, respectively. In the case of athletic subjects, the DRI predictive equation showed a clear bias negatively proportional to the subjects' TEE. CONCLUSIONS: The results from this study suggest that the DRI predictive equation could be used to obtain EER in non-athlete female college students at a group level. However, this equation would be difficult to use in the case of athletes at the group and individual levels. The development of a new and more appropriate equation for the prediction of energy expenditure in athletes is proposed.

To study the influence of leadership types on achievement goal orientation of high school athletes, Multifactor Leadership Questionnaire (MLQ) and Task and Ego Orientation in Sport Questionnaire (TEOSQ) were used to two-hundred-ninety athletes in Physical Education High Schools. The data from the survey were analyzed by SPSS 19.0 and the results of the analysis were as in the following. First, there were meaningful differences in the leadership factors according to the demographic characteristics. Male athletes tended to be more conscious of the individualized consideration(transformation leadership), contingent reward, management by exception(transactional leadership) of the leadership factors. Second, there were differences in athletes' achievement goal orientation. Comparing to the female athletes, male athletes gave more importance on the task goal orientation. Third, there were differences in the leader's leadership types on the athlete's achievement goal orientation. The athletes with self goal orientation and the individualized consideration (transformational leadership) of leadership types showed statistically meaningful differences. The athletes with high self goal orientation had a negative relationship to the individualized consideration and a positive relationship to the intellectual stimulation. The athletes with task goal orientation showed differences in the transactional leadership as well as in the contingent reward.

The balanced performance of dominant and non-dominant leg is very important to Taekwondo sparring. The purpose of this study was to investigate whether elite Taekwondo athletes would have balanced biomechanical performance and intra-limb coordination in executing different types of Taekwondo kicks. Twelve athletes(more than 10 year practice experience) participated in this study and performed six basic kicks(i.e., the front, roundhouse, side, back, thrashing, and turning-back kick). Results indicated no statistical difference on response time, peak kicking velocity, single limb vertical jump height, and angle-angle plot between dominant leg and non-dominant leg(p>.05). In conclusion, elite Taekwondo athletes had equivalent ability between dominant leg and non-dominant leg in performing Taekwondo kicks. This might be an advantage to elite athletes for Taekwondo sparring because they could use both leg without any restriction.

The purpose of this study was to examine the structural relationship among organizational justice, athlete satisfaction, team commitment, and organizational citizenship behavior toward college athletes. To achieve this purpose, this study employed a convenience sampling method via a questionnaire dissemination. A total of 285 responses were collected from college athletes. Among those, 21 responses were excluded as they were not completed, leaving 264 usable data. The data was computed in SPSS 28.0 and AMOS 28.0, and analyzed with correlation analysis, reliability analysis, confirmatory factor analysis, and structural equation modeling analysis. Overall, organizational justice had a positive influence on athlete satisfaction, team commitment, and organizational citizenship behavior. Athlete satisfaction had a positive influence on team commitment and organizational citizenship behavior. However, there was no relationship between team commitment and organizational citizenship behavior. These findings provided empirical foundational data on the impact of organizational justice on psychological and behavioral outcomes and the overall efficiency and effectiveness of organizations, with a focus on college athletes who played a central role in the context of college sports setting.

The purpose of this study is to verify the research model and identify the causal relationship among leader's super leadership, self-leadership, psychological empowerment, sport commitment and performance perceived by Taekwondo athletes. The subjects of the study were middle and high school Taekwondo athletes registered in the Korea Taekwondo Association in 2020 and 2021, and data from 454 people were used as final effective samples through convenience sampling. The collected data used the SPSS 23.0 version and the Amos 21.0 version to verify the hypothesis. As a result, the following conclusions were obtained. First, we discovered that the leader's super leadership had a positive impact on the athlete's self-leadership, psychological empowerment, and sport commitment. Second, we found that the athlete's self-leadership had a positive effect on psychological empowerment, sport commitment, and performance. Third, we found that athlete's psychological empowerment had a positive effect on sport commitment and performance. Fourth, we found that the athlete's sport commitment had a negative effect on performance. Therefore, this study has reminded us about importance of psychological empowerment and sport commitment for explaining the relationship between leadership type and performance perceived by Taekwondo athletes, and might contribute to the theoretical discussion of variables related to athletes' performance.

The purpose of this study was to investigate the relationship among perfectionism, stress, and burnout in college golf athletes. Participants were 221 college students. Self-oriented perfectionism and socially prescribed perfectionism were found to be the antecedent variables causing stress. Self-oriented perfectionism reduced personal accomplishments, and socially prescribed perfectionism increased the level of burnout. Additionally, perceived stress not only engendered emotional exhaustion but also reduced personal accomplishments. Regarding indirect effects, self-oriented perfectionism and socially prescribed perfectionism increased the level of stress and affected athletes' emotional exhaustion and lack of accomplishments. The results will be of use for helping athletes to escape from the perfectionism that occurs due to their obsession with winning, thus laying the foundation for athletes to continue to enjoy their sports.

Management of nutrient intakes through behavior-mordification can be important for improving exercise performance in athletes. The purpose of this study was to determine the effectiveness of nutritional counseling for improving exercise performance capability in athletes. The subjects were seven golfers and fourteen ju-do athletes from Hoseo university, and they have nor received professional hel[ from dieticians. Prior to nutritional counseling, their dietary intakes, lifestyles and dietary habits were evaluated. Nutritional counseling sessions were conducted by a trained dietician every 2-3 weeks for 3-4 month. After 5 counseling sessions, nutrient intakes, lifestyle and dietary habits were re-evaluated. Exercise performance capability was measured by maximal exercise stress test using treadmills. Individual data were assessed as quality index represents the better nutritional status. The common dietary and lifestyle problems were overeating binging, overeating, snacking and drinking alcohol prior to the nutritional counseling. After counseling sessions, the quality index of dietary habits seemed to decrease, especially in ju-do athletes, representing nutritional problems were resolved. Body fat and body mass index decreased in ju-do athletes, but not in golfers. Both athletes have shown to increase oxygen uptake at anaerobic threshold and maximal oxygen uptake status, which represents that the athletic performance capacity was improved after counseling sessions. Their respiratory quotients were decreased. In conclusion, nutritional counseling sessions over five times are an effective and efficient approach to change dietary habits to improve exercise performance capacity. Furthermore, clients can have good dietary habits and learn how to manago muscle strength by behavior modification through multiple nutritional counseling sessions.
