[Vestibulo-spinal and vestibulo-ocular reflexes in athletes]

There have been done tests of vestibulo-spinal et vestibulo- ocular reflexes at record-seeking sportsmen. At 141 sportsmen the vestibulo-spinal reflexes were tested by Unterberger-Fukuda stepping test in modification of Zilstorff-Pedersen and Peitersen. The angle of rotation (a), the distance of translocating to front or back (b) and the distance of sideward translocation (c) were estimated. The test was also done at 194 persons not playing sport. Comparing the average results of both groups the conclusion was drawn that sportsmen are characterized by lesser translocation of body within the range of all parameters of test, and differences of average are statistically substantial at the level of trust p = 0, 001. The vestibulo- ocular reflexes were tested at 62 sportsmen by caloric test by method of Fitzgerald-Hallpike with electronystagmographic registering of nystagmus. The control group consisted of 30 persons not playing sport. The following features of nystagmus were estimated: duration time, maximum frequency, maximum amplitude and maximum angular velocity of the slow phase. The sportsmen were characterized by average lesser calorie excitability of labyrinth, although the differences between the tested groups were statistically substantial only within the range of some features of nystagmus.
