Two balance elements (free support vertical split and frontal split) were analyzed in a group of 8 aerobic gymnasts (average age = 17,0 ± 1,3 years, average body height = 163,0 ± 6,9 cm, average body weight = 54,5 ± 6,12 kg, BMI 20,4 ± 1,46 kg.m-2). The FiTRO Sway Check stabilographic system, allowing the monitoring of horizontal movement of centre of gravity with the help of dynamometric board, was used for assessment. Stabilographic parameter of the velocity of the centre of pressure (mean and in antero-posterior and medio-lateral directions) was registered at 100 Hz. The results show significant differences in average sway length in medio-lateral and antero-posterior direction, in both analysed difficulty elements. This indicates that balance impairment after exercise and its readjustments to pre-exercise level depends not only on intensity of proprioceptive stimulation but also on type of exercise. Keywords: aerobic gymnastics, balance, postural stability. Introduction Stability, as a representation of body control through strenght, coordination, and efficiency of movement, involves a complex interaction between sensory organs, central processing, and motor elements (Foran, 2001). Maintainance of stability is the baseline for the most of body movements. It is generally accepted that stability is considered as a main factor infuencing the sport performance such as biathlon (Seljunin & Fomin, 1988; Aalto et al, 1990), gymnastics (Vuillerme & Danion & Marin, 2001), figure skating, rockenroll (Pelikan et al, 2004 ), basketball (Perrin et al, ), tennis (Psalman & Kasa, 2001), windsurfing (Psalman, 1997)) or sailing (Psalman & Kasa, 2001) and even small changes in post-exercise postural stability can affect athlete’s performance.
