Abstract
The aim of the study. The posture control is contributing by interaction of different orientation senses and motor control centers. The aim of this study was to define the level of neural coordination in alpine skiers (AS) and biathlonists (B) using the stabilography .Material and methods. 21 alpine skiers BM 63,3±8,58 [kg], height 167,2±8,84 [cm], age 16,7±2,11 [yr] and 22 biathlonists BM 66,1±7,59 [kg], height 174,4±6,88 [cm], age 19,1±1,52 [yr] took part in experiment. Subjects were required to stand on the platform which identified the location of mean pressure forces on the ground. Body sway was measured under each of following conditions: eyes – open (I), eyes – closed (II) and visual feedback (III) conditions, every time by 32 sec.Results. 3 of 14 parameters were significantly poorer under eyes – open and eyes – closed conditions in AS vs. B. Under visual – feedback condition AS had significantly poorer results than B except parameters of velocity sd in lateral and anteroposterior sway. Visuo-motor coordination is significantly higher in B (86,6%) than in AS (70,5%). The comparison inside groups shows univocally poorer stability with eyes – closed in both groups and poorer stability in AS group under visual – feedback condition.Conclusions. The mechanism of static equilibrium in biathlonists is much efficient then in alpine skiers. Also biathlonist characterized better visuo – motor coordination.
