Impact of 9-week strength training of racing cyclist candidate during training camp on body composition, racing cyclist specific fitness, and racing cycle performance was examined. Two by two (cyclist experience, y/n and strength training (ST) participation, y/n) experiment design was employed. A total of 20 candidates participated and divided evenly into four groups; 1) experienced cyclist participating ST (CST), 2) non-experience cyclist participating ST (nCST), 3) experienced cyclist no participating ST (CnST), and 4) non-experience cyclist no participating ST (nCnST). Two programs were introduced; 1) non ST containing, pre-existing program emphasizing on sprint and acceleration training and 2) new-program containing ST and sprint and acceleration training. CST and nCST participated the latter program. Before and after the 9-week training, body composition, racing cyclist specific fitness, and racing cycle performance was tested. After 9 weeks, all groups decreased body weight(p<0.05), body fat content(p<0.05), body mass index, and CST and nCST increased lean body mass(p<0.05). Muscular strength measures such as grip strength, low back strength, 1RM of bench press, 1RM of squat, and anaerobic capacity improved after 9 weeks in all groups(p<0.05). The magnitude of changes was greater in order of CST, nCST, CnST, nCnST. Time trial of 200 meter sprint was faster after 9 weeks in all groups except CnST while 500 meter sprint was improved only in nCnST(p<0.05). After 9 weeks, regardless of previous cyclist experience, those who participated in ST ranked high places at racing cycle competition. Both training programs for the candidates improved body composition and racing cyclist specific fitness. When strength training was added to pre-existing training program emphasized on sprint and acceleration, the racing cycle performance was enhanced. Strength training for racing cyclist is highly recommended to improve their racing performance.
The purpose of this study was to examine psychological capital acquisition through Asian Games Participation. 17 of national women football players were completed Psychological Capitals Questionnair. The psychological capital consists of optimism, psychological skills, self-management, collective efficacy, and performance perception was investigated after the team call-ups and before the team-release. The data was analyzed by paired t-test. As results, Korean women football players’ collective efficient and performance perception showed a statistical significance at the beginning of the team call-ups but optimism, psychological skills, and self-direction did not show statistic significances. The team-harmony, interpersonal-management, team-power, sufficient training, trust in coach, efficient communication, and psychological football factors, which were subfactor of football players’ psychological capital, showed statistical significances. However, confidence, concentration, goal-setting, imagery, willpower, anxiety-control, mental-management, life-management, training-management, innate-behavior management, physical-management, football skills, mediative skills, and football intelligence factors did not have statistic significances. These results demonstrate that effects of mega sporting events-like experiences and psychological factors’ variability and inflexibility according to weather changes should be considered when it comes to discussion of psychological factors regarding players’ performance. It is expected that this study would be a fundamental resource for understanding of psychological influences through participations in mega sporting events and discussions about further psychological interventions for teams with environmental consideration as well as methodological developments which could measure effects of the psychological interventions.
Purpose The following study was conducted to suggest and verify the validity of the concept of team performance, which has previously been considered as the total sum of individual performances. Method The concept of team performance was extracted by a conductive content analysis and an exploratory factor analysis of the data gathered from middle school football players. To verify the validity of the extracted concept, football experts' opinions were collected. Results The idea of team performance, categorized by Footballship, Team Capability, Personal Capability, Communication among Members, has been taken differently from the total sum of individual performances. Footballship is the virtue that should be materialized, and simultaneously earned during the game. Team Capability is a available resource for team's performance, Personal Capability is a available resource for a player's performance, and Communication among Members is the intimacy of communication between coaches and players. The conglomeration of experts' opinions on the concept of team performance and its components shows that team performance is evidently different from the total sum of individual performances. Conclusion The following study has been conducted to suggest and verify the validity of the concept of team performance. Team performance exists, standing distinct from the sum of individual performance, and understanding the concept of team performance will contribute not only to understanding performance, but also to improve the effectiveness of training and managing the team. Interest of the sport society is looked forward to.
Purpose The purpose of this studied to improve athletes’ performance through sports psychological skills training and counseling of a male canoe player in high school. Methods One male high school athlete in J area was interviewed for sports psychological skills training and counseling, and interviewed athletes and coaches diagnosed the potential psychological problems of athletes. Through this process, the athlete gained the ability to control anxiety about the game and strengthened the attention-focused ability to increase his confidence and set a goal for improving concentration. For effective training, sports psychological counselors, athletes, and coaches met once a week to create a routine. and participated in direct training on a boat with the coach every week. Sports psychological skills, anxiety about competition, and self-management of athletes were measured before and after to confirm the effectiveness of training of athletes' psychological skills. Results As a result, athletes' psychological skills and anxiety decreased, their confidence increased, and their concentration, which was diagnosed as an urgent problem of athletes, improved. Conclusions psychological skills of athletes, psychological shortcomings of players were reinforced, thus enhancing the athletes' performance. This suggests the effectiveness and necessity of training in sports psychological skills.

This study has been conducted to develop methods and techniques for the analysis of data related to baseball performance using the winning and losing games. The purposes of the study were to examine differences of athlete performance for semi playoff, playoff, and Korean professional baseball series and to develop optimal forecasting model for the short term series. Data used in the study were taken from Korean professional baseball association. Three data sets including semi play off from 1982 to 2012, play off from 1989 to 2012, and Korean series from 1982 to 2012 were used. To compare athlete performance by winning and losing games for short-term series t-test was applied. This study created new parameters by weighted value through the equalization process to calculate skill related variables as a predicted variable. Three predicted models such as discriminant, binary logistic regression and artificial neural network models were developed to clarify the suggested models. The results showed that the number of significant parameters increased as the series continued. In particular, a variable related to error was added as a significant variable at the Korean Series. A third base hit in the play-off and a second base hit were also added as significant parameters in the play-off and the Korean series, respectively. In addition, W/L a major variables affecting a given technology area, the pitching PO, PO, the inertia, KS, the pitching, respectively. An artificial neural network model was finally selected with the highest accuracy and lowest input of estimated parameters in the semi play-off. In the play-off, artificial neural network model that applied technical area parameters by specialist criteria had better accuracy rate than two others. In the Korean series, artificial neural network model that created estimation parameters by applying all parameters was chosen as the final model. When the overall accuracy level of semi-play off, play off and Korean series was figured out, binary logistic regression model had higher accuracy of classification than discriminant model, but artificial neural network model had the higher accuracy of classification than binary logistic regression model.
PURPOSE The purpose of this study was to investigate the characteristics of field and on-ice performances of ice-hockey players and the relationship of performance with subjective joint pain and dysfunction. METHODS A total of 25 male college icehockey players were evaluated for 19 items of performance. Pain and dysfunctions in the lower extremities and lower back were confirmed through the Foot and Ankle Outcome Score, Knee Injury and Osteoarthritis Outcome Score, Hip Dysfunction and Osteoarthritis Outcome Score, and Osweatry Disability Index questionnaire. Players with similar performance characteristics were classified through a cluster analysis, and differences in performance and patient-reported outcomes between clusters were analyzed with a one-way analysis of variance. RESULTS The ice-hockey players were classified into “lower muscular strength and performance (cluster 1),” “lower cardiorespiratory endurance (cluster 2),” and “high muscular strength and performance (cluster 3).” Players in cluster 1 had more frequent ankle and knee joint dysfunctions and pain compared to those in cluster 3. Several performance test items affected the subjective joint score, and the related performance items were more in the proximal joint than in the distal joint. CONCLUSIONS Ice hockey players should perform training to supplement their individual lack of on-ice and field performance. Since performance may be limited because of joint dysfunction and pain, a joint-specific intervention strategy should be applied to improve physical and athletic performances.
Purpose This study was aimed at interpreting the football talent development stages based on complexity theory. Methods The data for this study was gathered through literature review and in-depth interviews that were analyzed by thematic analysis.
