Dynamics of stabilometric parameters in the head turn test in student-athletes

Aim. The article deals with studying the dynamics of stabilometric parameters during head turns in college students involved in symmetrical sports. Materials and methods. Third-year college students (n = 24) involved in symmetrical sports (volleyball, basketball, rowing, swimming) participated in the study. The average age is 18.2 years. The study of stabilometric parameters was carried out following the procedure of the “Head turn test”. Results. In a basic European stance, we registered a shift of the common center of pressure (CP) to the back and the left. The parameters of balance had average values. The quality of balance function was 89.43%; movement values were 63.08 rad/s. During right head turns we registered the increase of the CP root-mean-square deviation along the frontal line. During left head turns we registered a statistically significant increase of the CP root-mean-square deviation along the frontal line with a shift of the common center of pressure to the back, a statistically significant decrease of balance function to 79.35%, and a parallel increase of movement values to 74.08 rad/s, which prove balance worsening. Conclusion. Left and right head turns provoke different dynamics of the parameters studied. In particular, there are changes in deviation values. Movement values and the quality of balance function had statistically significant differences only during left head turns. It proves balance worsening in a European stance in college students involved in dynamic sports. The analysis of the CP root-mean-square deviation allows us to conclude that students had circulation disturbance in the vessels of the vertebrobasilar artery to the right.
