  • In this study, we analyzed the balance of the both legs and the kinematic analysis of the upper limb segments and joints during archery shooting and compared the differences according to the scores. 9 K-university elite archery athletes participated. Each archer was asked to shoot 3-shots and 5-ends on a 122 cm target at a distance of 70 m. Seven infrared cameras (Qualisys, sweden) and two force plates (Kistler, Switerland) were used to calculate the upper limb segments and joint movements and the center of pressure (COP). When the archers shot 8 points, range of motion of elbow joint angle on drawing-arm and mediolateral COP range of motion on the left foot were larger than when 9-10 points were shot (p<.05). In order to maintain a high score in the archery game, constant balance is required, and the balance of the left foot supporting the bow during the shooting is an important factor. In addition, minimizing elbow joint movement of the drawing-arm supporting the bow will help stabilized shooting.

  • Objective: This study aimed to analyze how the upright body type exercise program affected body balance and record of archers. This study aimed to prove the effectiveness of upright body type exercise, on this basis, in enhancing the performance of archery players. Method: A total of 14 archers (7 men and 7 women) in B Metropolitan City who had ${\geq}4years$ of career in archery and were given explanation of its contents and purpose before giving spontaneous consent to the experiment were enrolled in the study. The upright body type exercise program was implemented thrice a week for 12 weeks, with higher exercise intensity with time. A resistive pressure sensor, Gaitview AFA-50, was used to measure the foot plantar pressure distribution and analyze quantitative information concerning variation in posture stability and weight shift in dynamic balance of foot plantar pressure in shooting and static balance of plantar pressure with the eyes open and closed and the change in archery record accompanying the change in body balance. Results: As for the differences in foot plantar pressure between before and after participation in the upright body type exercise program, there was no significant difference in static balance of foot plantar pressure with the eyes open, and there was statistically significant difference at the ${\alpha}=.05$ significance level in static balance of foot plantar pressure with the eyes closed or in dynamic balance of foot plantar pressure in shooting. There was statistically significant difference at the ${\alpha}=.05$ significance level in archery record. Conclusion: The upright body type exercise program had positive effects on static and dynamic balance of foot plantar pressure by allowing archers to experience less body sway and physical imbalance in shooting with closed eyes and positive effects on archery record. Thus, the program is expected to help archers correct their posture and perform better.

  • This paper presents an investigation into the forms of master archer Huhdai Mergen from Mongolian mythology and his character through archery. In Mongolian mythology, master archer Huhdai Mergen is usually connected to the regulation of the sun, the moon, and the stars in Heaven and the creation of stars. Such a series of acts are conducted through archery, which used to be performed as an incantatory ritual to resolve a disaster in life, dispel an evil spirit, and pray for affluence as well as for hunting. In Mongolian mythology, Huhdai Mergen is a master archer and hunter that rises to Heaven while hunting a deer and becomes Sirius with the deer becoming Orion. The Mongolian have believed that the two constellations protect them since ancient times. While Orion is related to the deer totem, Huhdai Mergen or Sirius is related to the wolf totem faith. Huhdai Mergen takes too much pride in his archery skills and ends up causing damage to himself, which can be understood as a pattern of controlling the power of personified Huhdai Mergen through excessive natural force. He also has something to do with Polaris, which is regarded as the stake to bind his horse to by the Mongolian. They also believe that their ancestral gods reside in the horse stake or column. The stake is the residence of Huhdai Mergen protecting the Mongolian people, which reflects his aspect as an ancestral god. He is also depicted as the god of thunder and lightning born in a cow. The stones he throws and the arrows he shoots in Heaven are the embodiments of thunder and lightning. The Mongolian have understood lightning of dispelling an evil spirit and striking wicked things as the arrow of Huhdai Mergen. The god of thunder and lightning has the attributes of a fertility god such as eliminating bad devils and bringing affluence. Huhdai Mergen is also manifested as the creator to create the earth and the savior to save mankind. Such forms all derive from his archery skills.

  • The purpose of this study is to monitor the physiological changes by measuring EEG, blood pressure, heart rate, etc after applying progressive relaxation technique to university archery players in order to verify the effect of progressive relaxation through respiration, and, ultimately, improve an athlete's archery performance. This study chose 13 female archery athletes. The EEG, blood pressure, and heart rate of the athletes were measured before applying Jacobson's progressive relaxation technique for 12 weeks, during which the EEG, blood pressure, and heart rate were measured 3 times a week after 15 to 20 minutes of training before every measurement. We used the SPSS18.0 program for technical analysis to check the general features of the athletes and carried out the paired t-test to examine the changes made to the EEG, blood pressure, and heart rate of a single test group before and after the experiment. All statistical level of significance was maintained at ${\alpha}=0.5$. The results are as follows. First, after 12 weeks of appliance, between the targets' relative ${\alpha}$ wave and ${\beta}$ wave, the relative ${\alpha}$ wave showed a statistically significant increase while the relative ${\beta}$ wave showed no changes. Second, after 12 weeks of appliance, in terms of blood pressure, the systolic pressure showed no changes while the diastolic pressure showed a statistically significant change. Third, there was no statistically significant change to the heart rate. In conclusion, progressive relaxation through breathing has a positive effect on the archery athletes.
