요약2 The changes of kinematic factors during archery shooting motion are still unknown in Korean traditional archery. This study investigated to evaluate of kinematic factors and each joint muscle strength during archery shooting motion in Korean traditional archers. Ten men Korean traditional archers were divided into two groups according to the shooting stance; parallel stance group (PSG, n=5) and oblique stance group (OSG, n=5). The 3-phase time of PSG was significantly longer than that of OSG during shooting motion (p<.01). On the other hand, there was no difference between the two groups in body weight movement measured by ground reaction force (NS). In the comparison of joint muscle strengths, dominant arm (draw arm) had significantly higher means in total upper limb muscle (TULS) with shoulder flexion+extension (SFES), shoulder external+internal rotation (SERIRS), total shoulder (TSS), wrist flexion+extension strength (WFES) than non-dominant arm(bow arm), respectively (p<.05, p<.001). As for the correlation between each variable, significant negative correlation was found between highest score and dominant body weight movement in the 3-phase time (p<.01). However, significant correlation was found among bowstring tension and average hand grip strength, non-dominant hand grip (NDhand grip), wrist extension (NWES), and shoulder external rotation strength (NSERS), respectively (p<.01). These results suggest that the muscular strength of joints in the dominant arms is an important factor for Korean traditional archery, and the parallel stance is might more advantageous to shoot than oblique stance.
