Siebert D, Sklortz E, Espig N. Electromyographic activity of the M. biceps brachii in various shooting positions in the standing position in biathlon shooting. Clinical Sports Medicine International (CSMI) 2013, 6(1): 8-13.
Objective: The importance of shooting performance in biathlon is continuously increasing. A strong performance in precision tasks is necessary for high shooting results. Therefore the shooting position has to ensure a stable foundation of athlete and rifle. It remains unanswered how different shooting positions affect the muscular activity of musculature responsible for fixation of the weapon during shooting. The aim of this study was to make a contribution in forming a valid tension profile of musculature involved in standing shooting position in biathlon.
Materials and methods: The research of the present study was carried out on seven athletes of the German Junior-National Team. Every subject had to complete three shooting series in a 15 s interval in standing position with three different positions of the butt plate. During the shooting series the angle of the shoulder axis, as well as the electromyographic activity of the M. biceps brachii were quantified.
