The purpose of this study was to examine the effect of dietary creatine and leucine supplementation on protein synthesis and functional properties of skeletal muscle during 8 weeks of resistance exercise. Thirty two male Sprague-Dawley rat(5 weeks old) were randomly divided into four groups(8 rats per group): sedentary control group(CON), execise group(E), exercise with creatine supplementation group(EC), exercise with creatine, leucine supplementation group(ECL). Exercise groups were trained to climb a ladder with a weight secured to their tails(3day/week). The supplementation was administrated daily through oral gavage. Creatine supplementation was given at 250㎎/㎏/day. Creatine+leucine supplementation was given at 250+250㎎/㎏/day. All exercise groups presented significantly lower epididymal fat mass than CON(p<.05). E presented significantly higher plantaris mass than CON(p<.05). All exercise groups significantly presented higher FHL mass than CON(p<.05) and E presented higher FHL mass than EC, ECL(p<.05). EC, ECL presented significantly lower expression of Akt/PKB protein than CON, E(p<.05). There was no difference in the expression of mTOR protein. The results suggest that the creatine and leucine supplementation does not promote any additional hypertrophic effect on resistance trained skeletal muscle. But, creatine and leucine supplementation might have a potential benefit on skeletal muscle hypertrophy through the activation of protein synthesis.
This study measured the accessibility of public exercise facilities within a residental area of a metropolitan community and examined how the accessibility can affect physical activity participation of residents. Initially, a total of 639 residents, who were aged between 19-70, visited Metabolic Syndrome Management Center of the Community Public Health Center, and registered for a Obesity Clinic Program, was listed as potential subjects. And those who responded to Physical Activity Questionnaire were selected for the analyses (n=92, 14.3% of 639). The relationships between physical activity level and accessibility to public exercise facilities were analyzed. Objective distance to public facility was related to ‘volume of participation to vigorous physical activity(r=.209)’, 'total volume of participation to physical activity(r=.206)’. And perceived distance to public facility was related to ‘volume of participation to vigorous-intensity physical activity(r=.235)’. perceived transport time to public facility was related to ‘duration of participation to vigorous-intensity physical activity(r=.239)’, ’volume of participation to vigorous-intensity physical activity(r=.306)’, and ‘volume of participation to total physical activity(r=.273)’. In contrast, the difference between objective distance to public facility and perceived subjective distance to the facility was negatively related to ‘duration of participation to moderate-intensity physical activity(r=-.221)’. The perceived numbers of public facility was positively related to ‘frequency of participation to vigorous-intensity physical activity(r=.237)’, ‘frequency of participation to walking(r=.273)’, ‘volume of participation to walking(r=.251)’ and 'total volume of participation to physical activity(r=.252)’. The predictor of 'total volume of participation to physical activity was perceived numbers of public facility(R2=.153, p=.046). The results revealed that the subjective accessibility to public health facilities was more influential to physical activity participation than the objective accessibility. Further research was warranted while using diverse populations as well as considering a inclusion of environmental factors.
The purpose of this study was to classify high school baseball players as superior or inferior group by Functional Movement Screen(FMS) and to provide basic information for finding great pitcher and improving exercise performance by comparing and analyzing the pitching motion. The results of this study are as follows. The inferior group’s center of mass(COM) moved significant on the left side than superior group at heel contact(HC), ball release(BR), and follow throw(FT)(p<.05). There were no significant difference in linear velocity of shoulder, elbow and wrist between two groups, but inferior groups showed large difference in each joint. The superior group controled rotation of pelvis at HC and showed significant higher knee extension at BR and FT than inferior group(p<.05). The angular velocity of superior group’s throwing arm were higher in acceleration period(p<.05). Taken together based on the results, the players who have higher muscle function showed great pitching motion, so we can conclude that FMS could be useful for evaluating the potential of pitcher.

There are expanding the base of amateur baseball with diverse factors and corporations are getting more interested in making opportunities to build relationships with customers by using this phenomenon. However, the previous research did not focus on examine practical effectiveness for relationship marketing methods as the strategy of the building relationship which was applied to sport events from diverse corporations. Therefore, the purpose of this study is to examine the practical effectiveness of the relationship marketing methods and the influencing process of the relationship marketing strategy applied to the amateur baseball. 150 players who took part in the amateur baseball tournament hosted by the on-line shopping mall company were selected for research samples with random assignment. To examine the practical effectiveness, 136 players' survey responses out of 150 responses were used for research data. For hypotheses testing, this study applied PLS structural equation model. This study presented that perceived face to face and listen as relationship marketing methods were significantly positive influenced on perceived relationship quality. In addition, perceived relationship advertising as relationship marketing methods were significantly positive influenced on perceived purchase intention. Moreover, perceived relationship quality was significantly positive influenced on perceived purchase intention. In the case of mediating effect with considering relationship quality, there was partial mediating effect for relationship advertising and face to face, and there was complete mediating effect for listen.
Although mega sporting events are becoming an effective means of brand communication, there has not been systematic research on involvement development and perceived fit enhancement through the sporting events. This study developed and tested a conceptual model delineating the impact of consumer involvement on perceive fit, and brand equity in mega sporting event context. Using quota sampling method, 1,847 participants (916 from IAAF; 931 from the F1) were recruited from several different cities in Korea during the mega-sporting events. Structural equation modeling were employed to examine the relationship between research constructs and test the model respectively. The study found that mega event involvement has a positive effect on perceived fit; and perceived fit influences brand equity(brand awareness, perceived quality and loyalty) toward event sponsor brands. The direct effects of involvement on sponsorship effectiveness (brand awareness, perceived quality and loyalty) did not have a significant effect on brand equity. The findings also reveal the mediating effect of perceived fit on brand equity.
The purposes of this study are to analyze sports scenes or sports characters seen in the Korean films which are not using sports as main material, to identify the sports images that appear in the selected movies, and to deduce the formation of these images' structures. For these analysis, we selected 10 movies which had more than 1 million visitors and premiered after 2000. We used text analysis method to examine the scenes and dialogues appear in the movies. In order to ensure reliability and validity, peer review and experts' advices are used among the triangulation method. Also to enhance the realism of film analysis, a scene or dialogue in the film are presented by direct quotation. As the analyze result, three kinds of sports images seen in the movie characters are emerged: 'images of violence', 'images of deficiency' and 'images of failure'. Unlike sports movies which are using sports as a main material with a planned intention, 'sports images' seen in regular movies have negative images based on distortion and biased in sports. Thus, in subsequent studies, the reasons why the gaps between these images of sports are made should be studied.
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.
