Although many variables influence success in the sport, biomechanical considerations as reflected in correct or incorrect technique, particularly in gymnastics are more than decisive. The present study analyses relationships of the kinematic characteristics of Switch Split Leap 1/1 Turn to Split in culmination phase, executed by the Slovak aerobic gymnastic champion (age = 23 years, height = 158 cm, body weight = 52 kg). The indicators that appear to be a key in terms of correct technique were measured: the angles between the body segments, the height and velocity of the centre of the mass. Measurements were carried out by Simi Motion 3D system in the Laboratory of Biomotorics Faculty of Sports Studies, Masaryk University in Brno, Czech Republic. Eight synchronised industrial cameras were used to collect the data. Spearman's analysis confirmed the high degree of dependence between the leg angle of split position and the velocity at the culmination (r = 0.829). On the contrary, the correlation between the leg angle of split and the height of the centre of the mass was manifested as non-significant (r = -0.441).
