Abstract

|
The theory of visuo-vestibular conflict is the most commonly accepted to explain motion sickness. Visual, vestibular and proprioceptive afferences are in involved in balance control and this function can be improved by physical and sport activity. The purpose of the present survey was to investigate the relationships between motion sickness susceptibility in elite gymnastic & figure skating player physical activity and especially acrobatic exercise. We quantified vestibular-ocular reflex(VOR) in intensity in 7 figure skating and 7 age matched control subjects. Sensory organization test were by posturography in neuroCom EquiTest and vestibular stimulation consisted of four cycles of sinusodial rotation(.01, 04, .16, .64Hz, 60°/s) and was tested by system 2000 micromedical, Chatham, IL. The results of the study were as follow: The results are as follow. Balance score in condition 5, 6 were significantly higher than control. During sinusodial stimulations, the skaters’VOR, as compared with that of the controls, demonstrated a gain that significantly lower(p<.01), than in control one. Quantitative alterations in VOR parameters observed in gymnastic and figure skaters probably result from vestibular habituation induced by repeated unusual stimulations when practicing.
