THE INFLUENCE OF THE POSITION OF THE FEET IN THE MANUFACTURE OF AN ATHLETE-SHOOTER ON THE PARAMETERS OF ARCHERY SHOTS

The research purpose was to study the stabilographic and electromyographic characteristics of archery shots features at different feet positions of athletes.

Methods and organization of the research. The study involved highly qualified compound and recurve bow shooters. A stabilographic parameters and electromyographic activity of skeletal muscles were recorded during archery. The shooters performed 5 shot series (6 shots each) with different feet positions: the subject typical position, “45 degrees”, “parallel position”, V-type, T-type.

Research results. In the typical working stance, the compound bow shooters set the left foot to the firing line at an angle of -25,16±3,95 degrees and the right foot – at an angle of 5,78±1,86 degrees, the recurve bow shooters – at an angle of -22,75±2,74 degrees and 16,10±2,70 degrees, respectively. Changes in the athletes' stance had virtually no effect on the load asymmetry to the right and left foot, with the exception of the T-type position, in which the load asymmetry was significantly shifted to the behind standing foot. In relation to the typical subject position, there was a tendency to decrease the quality of vertical stability when performing shots in experimental feet positions. The compound bow shooters muscles’ electroactivity at experimental foot positions in relation to the one in typical foot position, on average, was different from 1 to 27%, in the recurve shooters – from 3 to 36% and did not achieve statistically significant differences.

Conclusion. An increase of the left foot supination leads to the higher load on the right foot. Vice versa, the supination of the right foot and the V-type stance increased the load on the left foot. The stance changing of highly qualified archers did not lead to the shoots results decrease, as well as the quality of postural stability and skeletal muscle activity decrease.
