Features of rugby players’ postural regulation by stabilometry data

Abstract

Objective: to analyze the postural regulation of rugby players. Materials and methods. 10 rugby players performed Romberg test and optokinetic test on a computer stabilograph “Trust-M Stabilo”.Amplitude and frequency characteristics, length, area of statokinesiogram, ratio of length to area; speed of center of massmovement and the work have been analyzed.The results were compared with those of healthy people not involved in sports. Results. Athletes’ deviations and area of the statokinesiogram were greater than in the control group, though the length of the statokinesiogram was shorter. Maintaining the vertical posture required less work in athletes group. Eyes closing was accompanied by increasing the area of statokinesiogram, the speed of center of massmovement, and the frequency of oscillations in sagittal plane. Visual disturbances led to an increase in speed of center of massmovement, in length of statokinesiogram, in standard deviation and in shift of center of mass back. The effect of disturbances in athletes’ group led to fewer changes than in the control group.Conclusions. Postural regulation of athletes proved to be better than that of healthy people who are not involved in sports. All rugby players had a similar strategy for working out disturbances.
