PURPOSE This study aimed to apply a team-building program for preparing the national archery team for competition in the Olympics. METHODS To achieve the purpose of this study, six national archers (three men and three women) were included. The team-building program was applied for a total 6 sessions (one session per week). Group cohesion and efficacy were measured three times before, after, and at a later application of the program. The collected data were analyzed with the Friedman and Wilcoxon signed-rank tests, which are nonparametric statistical techniques for data analysis. In addition, an in-depth interview for qualitative data was conducted for each archer to explore the effects and changes resulting from participation in the program. RESULTS The results of the study are as follows: first, the levels of team cohesion and efficacy in the national archery team increased after the implementation of the program compared to those in the pre-implementation state. Furthermore, high levels of team cohesion and efficacy were maintained at the follow-up measurement. Second, the archers recognized that closeness and faith in one another increased more between team members. Furthermore, there were positive changes in team communication, atmosphere, cohesion, and efficacy during team matches. CONCLUSIONS The team-building program applied in this study was found to have a positive effect on various factors related to team cohesion, such as team communication and team atmosphere. Therefore, future studies should consider developing a team-building program that can contribute to improving team sport performance for different sports and the effects of the program should be examined using various methods.
Purpose The purpose of this study was to provide useful information on the improvement of performance by measured the psychological-physiological stresses experienced by elite shooters during a competition. Methods Thirty-eight elite shooters participated in this study (Male = 13, Female = 25). Psychological stress was measured and used for this study based on the stress factors found in the elite target stress study by Park(2015). The cortisol, a physiological stress hormone, was measured using saliva. Results The reliability of the psychological stress sub-factor pre-post analysis results showed no statistically significant. The concentration of cortisol measured on the day before the competition (0.1704 µg/dL) significantly increased immediately before the competition (0.3558 µg/dL). Cortisol immediately before the competition showed negative correlation (r=-.361, p=.036) with the competition score, and the regression variable of cortisol was 13%. Conclusions In this study, physiological stress had a negative effect on elite shooters performance compared to psychological stress.
This study was to verify the structure of efficacy related to performance perceived by short-track athletes when playing a match. Therefore, 50 players answered open questionnaires and 200 players participated in construct validity verification, a total of 250 players of short-track members of national, business and university team were sampled during the research phase. The data was analyzed through the study procedures. The results were as follows: First, efficacy structure of players during the match were categorized into three groups as game managing strategy(including course management, race control, match management and selective attention ability), psychological control ability(including positive imagery, match competition, competitive spirit, ability to handle hardship, anxiety control, and patience), and physical usage of ability(including physique, endurance, and quickness). Second, the result of the first construct validity verification through exploratory factor analysis showed 7 factors in 29 items as game management, course management, psychological control, physical use, coping with hardship, speed control and psychological stability. Finally, as a result of confirmatory factor analysis, short-track self-efficacy showed the 5 factor in 15 items except for coping with hardship and psychological stability.
Purpose The purpose of this study was to examine the difference and consistency of kinematic variables for each athlete by selecting the official records of the world's elite female triple jumpers to evaluate the performance level. Methods Three athletes who won the prizes at the World Championships Daegu 2011 Women's Triple Jump were selected as the study subjects, and only the successful trials were used for analysis. Pearson's correlation analysis was conducted with the kinematic variables in the hop, step, and jump phase, respectively. Also, kinematic variables with statistically significant correlations between braking time and pushing time and related variables were described separately. The duty factor and support factor for the hop, step, and jump of support phases were calculated. Results The successful trials rate were 66.7% for Olha, 50% for Olga, and 83.3% for Caterine. In the last three stride distances of the approach run, Olha and Caterine had a “medium-long-short” pattern and Olga had a “long-short-medium” pattern. There was no difference in the duty factor value between hop and jump phases in the ‘hop-dominate’ technique type, but there was a difference in the jump phase in the ‘balance’ technique type, and the duty factor value in the step of both technique types was greater than that of hop and jump phases. As for the percentage of the support factor, Olha and Caterine had a characteristic that the percentage of braking time in step and jump phases was opposite. On the other hand, Olga had the same percentage for the hop and step phase, and a smaller percentage for the jump phase. Conclusion To increase the accuracy of the board touch-down, maintain a certain last stride(1SL) depending on the technique type. This consistency of the approach run increases reduces distance loss on the take-off board and increases the successful rate of each trial. The duty factor can judge both the performance level and the technique type of triple jump, and the support factor is a variable that can classify the technique types of hop, step, and jump phases. If both the relative time required for the triple jump and the variability of the support time(braking and pushing) for each phase are constant, the difference in records by trial will be small.
This study employed a sportscape model to analyze environmental impact on spectators’behavior. In addition, the loyalty construct in the sportscape model was reanalyzed based on the theoretical framework. Five hundred questionnaires were distributed to the spectators of World University Taekwondo Championship, and 418 questionnaires were used for data analyses. The analyses of measurement and structural models were conducted using SPSS 18.0 and EQS 6.2 programs. The results indicated that the measurement model showed acceptable reliability and validity. The structural analysis showed that five stadium factors (parking, cleanliness, crowding, food service, and fan control) have significant effects on spectators’ desire to stay and to revisit the stadium. Loyalty also positively affected revisit intention. This study emphasizes sport environment to make spectators revisit and provides future research suggestions to improve the sportscape model.
PURPOSE This study aimed to identify the influence of certain factors on spectators' spectating behavior through the analysis of spectator-type Taekwondo spectators’ spectating behavior by applying the extended theory of planned behavior and embodied cognition theory and considering spectators’ desire to stay. METHODS A total of 305 surveys were used as the final sample. SPSS 24.0 and AMOS 26.0 were used for frequency , correlation, confirmatory factor, and structural equation model analyses. RESULTS First, attitudes, subjective norms, perceived behavioral control, and prior knowledge, which are predictors of the extended theory of planned behavior, had a statistically significant effect on the spectators’ desire to stay. Second, the spectators’ desire to stay had a statistically significant effect on the spectators’ content , environment, and behavior. Third , the spectators’ content and environment, which are sub-factors of the embodied cognition theory, had a statistically significant effect on the spectators’ behavior. CONCLUSIONS The study results suggest that attitudes, subjective norms, perceived behavior control, and prior knowledge, which are predictors of the extended theory of planned behavior, have a positive effect on the embodied cognition and spectator behavior of spectator-type Taekwondo spectators.
Purpose This study aims to investigate the experience of service yips in badminton players in depth through using grounded theory method. Methods We collected data from in-depth interviews with 14 participants in total, consisting of badminton players who experienced service yips, their doubles partners and coaches. The collected raw data were analyzed base on derive transcription, coding and paradigm models through grounded theory method. Results First, as a result, 59 concepts, 31 subcategories and 15 categories in regard to badminton service yips were deduced from open coding. Second, in axial coding, it was structured in a paradigm model by categories such as service yips, service mistakes, service proficiency, service anxiety, the imprinting experiences, the importance competition, the pressure of achievement, service practice, psychological control, tactical handling, support from partners, leaders’ coaching, advice from experienced ones, overcoming yips and persistent yips. Third, selective coding resulted in ‘Badminton service yips’ as the core category of this study. ‘Badminton service yips’ is a chronic performance impairment associated with badminton players making severe errors in swing motion on a service not intended by them that it is due to physiological or psychological symptoms such as hand tremors, overall body stiffness, arms stiffness, overstress, overanxiety, and concern over service mistakes. Conclusions We expect our study can be a theoretical foundation for understanding and explanation of ‘Badminton service yips’ and a useful reference for badminton players suffering from psychological difficulties caused by their service yips. The findings in this study should be considered for the development of potential strategies for overcoming the badminton service yips.
Purpose The aim of this study was to provide athletes and coaches on informations and benefits of a taper through evidence-based scientific studies and literatures in order to optimize an athlete’s top performance for the major competition. Methods Studies and literatures search was conducted using the databases RISS, KISS, SPORTDiscuss. Key words searched: taper AND(competition, OR performance, OR training, OR training). This study were eventually cited by 22 articles for results of this in total 100 articles. Results The training load is remarkably reduced during a taper. With a reduced training load, training intensity should be maintained during the taper. The training load reductions during the taper should be programmed with reducing training volume at 41% to 60% of pretaper training. The reduction of training frequency during a taper means that affect moderately trained athletes and highly trained subjects differently, reducing 30% to 50% of pretaper training and maintaining training frequencies, respectively. Detraining the duration of a taper is not easy. Most athletes is beneficial from a 2-week shorter or longer tapers, depending on their individual profiles of fitness loss, fatigue dissipation, and anxiety. The manipulations of this training program variables usually affect for most athletes and maximal performance gains. Conclusion Training intensity should be maintained during the taper, training volume reductions should be programmed at 41% to 60% of pretaper training. The reduction of training frequency could be reduced 30% to 50% of pretaper training, and most athletes is beneficial from a 2-week shorter or longer tapers. Future researches should be conducted the practical & effectual differences in individual and teamed-based sports after a taper procedure.

Each individual responded the questionnaires in pre- and post-treatment sessions. Data were analyzed by repeated-measure ANOVA. Furthermore, archers participated in the program responded to in-depth interviews. Results According to the results, participants in strength-based positive psychology intervention showed that significantly increased strength knowledge, strength use, and optimism in the post–treatment compared to the pre-treatment session while control group did not show significant changes. In addition, archers perceived that there were positive effect on thinking ·coping and their self-confidence and self-esteem enhanced after participating the program. Conclusion The results of this study suggested that strength-based positive psychology intervention has positive impact on athlete’s wellbeing and perception of individuals strength and can be applicable to different sports field.
Purpose The purpose of this study was to investigate the differences in physique and physical fitness according to maturity between primary and middle school baseball players. Methods Participants were 112 elite youth baseball players (49 primary school; 63 middle school). Skeletal age estimated maturity. Physique (height, arm span, thigh volume), body composition (weight, muscle mass and body fat), physical fitness (strength, power, agility, flexibility, coordination, anaerobic power and aerobic power) were measured. An independent sample t-test was used to conduct verify the difference between physique and physical fitness according to maturity. Results The results of analyzing physical and physical fitness according to maturity showed that there was a significant difference (p<.05) between the early maturation group and on-time group in primary school baseball players, body fat percentage, muscle mass percentage, sit-up, anaerobic power and reaction time. There was a significant difference between the early maturation group and the on-time group in the middle school baseball players, weight (p<.05), thigh volume (p<.05), fat mass (p<.05), muscle strength (p<.01), power (p<.05) and coordination (p<.05). Conclusions In conclusion, the maturity of a growing baseball player may be influenced by the performance, so maturity status should be considered when judging the performance of a growing baseball player, especially a middle school baseball player.
