The purpose of the current study was to evaluate the relationship between shoulder girdle muscular activation and hit distribution patterns on target. 6 female (age: 16.66±3.44 yrs; training age: 5.88±2.92 yrs) and 10 male (age: 22.33±12.95 yrs; training age: 4.11±2.80 yrs) subjects participated in the study. Each archer shot 12 arrows to a target at 30m distance. Bipolar surface EMG recordings were taken from anterior (DF), middle (DM) and posterior (DP) portions of m. deltoideus, and from upper (TU) and middle (TM) part of m. trapezius of both the bow and drawing arm. The target face was segmented into 4 distinct target zones and muscle activation was identified according to the actual target zone hit. iEMG % values of the bow arm muscles identified for the time period before the fall of the clicker, DM activation was higher for hits in zone 3 than in zone 4, TM activation value was higher for hits in zone 4 than in zones 1, 2, and 3 during the fall of the clicker. In the period of time between one second before and the moment of fall of the clicker, TU muscle activation in drawing arm was significantly higher for hits in the Zone 1 and Zone 4 than in Zone 2.
