Postural Stability in Aerobic Gymnastics Specific Positions
The study compares the effect of maximal jumps and sport-specific exercises on parameters of balance. 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.
