This study aimed to evaluate directional properties of elite indoor volleyball player's movement. Fourteen elite female players (age = 25 +/- 6 years; body height = 182.3 +/- 6.2 cm; body mass = 72.1 +/- 5.8 kg) were used for 3D kinematic analysis of movement by software TEMA Bio v2.3. (Image Systems Ltd., Sweden).
A total number of 4675 distances (4 sets; 41.8 +/- 2.2 rallies per set) were analysed for this study. Middle hitters (MH1 and MH2) participated in approximately 60% of all rallies (MH1 in 58.6 % and MH2 in 60.8 %) and the Libero participated in 80.3 % of total of 167 analysed rallies.
An average result for forward direction of the movement was 32.2 +/- 5.9 %. For backward direction it was 16.4 +/- 5.4 %, the right direction reached an average of 28.4 +/- 9.8 % and the left direction 22.9 +/- 6.1 %.
A total of 91.8 +/- 1.3 % of movement sections had their length from 0.7 m up to 2 m and 48.1 +/- 3.9 % of distances had their length between 1 m to 2 m. Overall, 8 % of the distances were longer than 2 m.
For a deep insight of real external workloads during the game conditions, such detail analysis of the movement is crucial.
