Background. Sport result in archery is provided by high accuracy (Clemente et al., 2011), which depends
on various factors such as environmental conditions, technique, and fatigue (Kolayis et al., 2014). The
movement itself is described as containing three phases: the stance, the aiming, and the releasing
(Leroyer et al., 1993; Ganter et al., 2010). Nowadays there are three stance positions, which the archers
adopt – the open, the square and the close stance. The aim of the pilot study was to compare the
influence of open, close, square stance and footwear choice on CoP displacement in sport archery.
Methods. One national level experienced archery female shooter participated in the study (33 years, 75
kg body mass, 165 cm height) with a recurve bow (38 lbs, 68"), athlete’s regular foot position – square
stance. CoP displacement was registered with two force plates (BTS, Italy). Athlete was asked to perform
3 shots from each stance barefoot, with sport shoes and with boots (total n = 27). Results. According to
the results more stable conditions were found in open stance barefoot (CoP area was 9.8 ± 2.2 mmq), in square stance with sport shoes (CoP area 9.8 ± 1.3 mmq) and in close stance with boots (CoP area 17.1 ± 2.7 mmq). There were high variations between the results of CoP radius and area in the same conditions, for example, CoP area in close stance barefoot for left leg was 16.0 ± 8.0 mmq. We did not find any clear relationship between CoP area and radius according to stance form or footwear. Conclusions. In future research it is necessary to increase number of shots and to find a solution for more accurate counting the aiming and the releasing phase. We believe that it could help to reduce high variation between the results in the same conditions.
