Background: This study evaluated the shoulder girdle muscle characteristics of elite archery athletes and provides suggestions for archery training programs. Methods: This study enrolled 15 cases of high level archery athletes (7 males, 8 females) and 30 cases of (15 males, 15 females) sex, age-matched, healthy, non-athletic individuals. We measured peak torques of flexion (FL), extension (EX), abduction (ABD), adduction (ADD), external rotation (ER) and internal rotation (IR) of both shoulders at an angular velocity of $30^{\circ}/sec$, $60^{\circ}/sec$, and $180^{\circ}/sec$. The peak torques and peak torque ratios of FL/EX, ABD/ADD, and ER/IR of the two groups were compared. Results: The archer group had a greater peak torque of IR and ADD, but only in the left shoulder (p<0.05). In the same group, both shoulders had greater peak torque of EX and lower peak torque of FL. The peak torque ratios of FL/EX of both shoulders were significantly lower in the archer group at all three angular velocities (p<0.05). The peak torque ratios of ABD/ADD were significantly greater in only the left shoulder of the archer group (p<0.05). Conclusions: The prominent characteristics of the shoulder girdle muscles of an elite archer are stronger adductor muscles of the bow shoulder and stronger extensors of both shoulders, as compared to healthy, non-athletic individuals. These muscle groups of the shoulder probably contribute a major role in maintaining the accuracy and stability during archery shooting. Hence, a training program that selectively enhances the adductor and extensor muscles could prove helpful in enhancing the archery skills of the athlete.

In modern society, the optimal physical environment is constantly changing due to IT development, and it is provided with convenience. In this age environment, the children are growing up thinking that the value of community consciousness through relationship with others is not important in the social reality in which various ways and environments that can be done by themselves are succeeding. No matter how rapidly the world changes, a diverse learning environment is needed that establishes desirable human relationships and recognizes community consciousness and values. The purpose of this study was to investigate the effects of general children(elementary school 4th, 5th, and 6th graders) on the communication and peer relationship of the children participating in the archery experiential learning program, to emphasize the importance of physical activity programs, and also by analyzing the relationship between communication and improvement of peer relationship and to understand the effect of the archery experiential training learning which is one of exercise program. In order to verify the research problems, 30 experimental group and 30 comparative group were composed of 4th, 5th, and 6th grade elementary schools in Gwangsan-gu, Gwangju metropolitan city. The experiment group was participated in the archery experiential learning program for a total of 10 sessions, once a week for 60 minutes, and conducted a questionnaire survey. In this study, we examined the effect of archery experiential learning program on improving children 's communication and peer relationship ability. Thus, it showed that archery experiential learning program can be one of the important educational methods to promote the healthy character and development of children.

The purpose of this study was to verify the relationship between perfectionism and job stress of archery trainers. Participants of this study were 113 archery trainers who worked at the middle and high school's archery teams. Some of the archery trainers who participated in korea archery championship for junior in 2007 were selected using the purposive sampling method. The questionnaire was Multidimensional Perfectionism Scale developed by Hewitt and Flett(1991) which was revised by Lim(2005) into Korean and The Job Stress Scale developed by Jo(1998). Responses were made on 5-point and 7-point scale. The statistical methods for the analysis of this study were Pearson's correlation and multiple regression analysis. The results of this study were as follows. First, there was self perfectionism, person perfectionism, social perfectionism highly on the perfectionism of archery trainers and job condition stress, game stress, job load stress, support system stress, interpersonal relation stress highly on the job stress. Second, there was statistical significant relation between the job condition stress, game stress, job load stress and self perfectionism, between the game stress, job load stress and person perfectionism. Third, self perfectionism affect on job condition stress and self and person perfectionism affect on game stress, job load stress.

This study aims to identify the effect of the mental health and leisure competence of senior citizen through participation in archery activity on satisfaction in their life. To achieve the purpose, the study interviewed members of the Archery and Sports Association living in Gwangju, Jeonnam and Jeonbuk using a questionnaire and collected 328 valid responses. The questions as measuring instruments such as leisure competence, depression, self-esteem, and satisfaction level which were developed by previous studies were revised for this study. For a statistics, a frequency analysis, a descriptive analysis, a correlation analysis, and a structural model analysis were conducted. As a result, first, the higher self-esteem of the subjects, the more they participated in archery and were satisfied with their life. Second, the lower depression they had, the more they participated in archery and were satisfied with their life. Third, as leisure competence of the subjects was not a main factor of archery participation, the related assumption was rejected. The mental health of the senior citizen such as self-esteem and depression was a factor of participation in archery and their satisfaction with their life grew higher through participation in archery.

In this paper, we provide a development and evaluation method for an archery posture analyzing system, using an inertial sensor. The system was developed using LabVIEW2014 by National Instruments and evaluated using the DTW algorithm. To convert the voltage value of the inertial sensor into a physical value, a coordinate transformation matrix bias was applied. To evaluate the similarity of movement in archery shooting, the DTW distance was calculated and similarity was confirmed based on simple mechanical movement, the same person's shooting movement, shooting movement with another person, and the noise signal. The average similarity comparison results were as follows: simple mechanical movement was 17.05%, the same person's shooting movement was 26.48%, shooting movement with another person was 62.8%, and the noise signal was 328.5%; a smaller value indicates a higher level of similarity. We confirmed the possibility of analyzing the archery posture using 3-axis acceleration of the inertial sensor. We inferred that the proposed method might be important means for assessing shooting skills, evaluation of archer's progress, and finding talented archers in advance.

Objective: The aim of this study was to investigate the relationship between aiming patterns and scores in archery shooting. Method: Four (N = 4) elementary-level archers from middle school participated in this study. Aiming pattern was defined by averaged acceleration data measured from accelerometers attached on the body during the aiming phase in archery shooting. Stepwise multiple regression analysis was used to test whether a model incorporating aiming patterns from all nine accelerometers could predict the scores. In order to extract period of interest (POI) data from raw data, a Dynamic Time Warping (DTW)-based extraction method was presented. Results: Regression models for all four subjects are conducted with different significance levels and variables. The significance levels of the regression models are 0.12%, 1.61%, 0.55%, and 0.4% respectively; the $R^2$ of the regression models is 64.04%, 27.93%, 72.02%, and 45.62% respectively; and the maximum significance levels of parameters in the regression models are 1.26%, 4.58%, 5.1%, and 4.98% respectively. Conclusion: Our results indicated that the relationship between aiming patterns and scores was described by a regression model. Analysis of the significance levels, variables, and parameters of the regression model showed that our approach - regression analysis with DTW - is an effective way to raise scores in archery shooting.
