The aim of this paper is to analyse in detail the aspects regarding increased efficiency of the spike in the game of volleyball, given the requirements of a flawless technique that will maximize the potential of the players. Our intention was to verify whether the steps of approach are unfolding in a uniformly accelerated motion and are leading to a vertical leap in the desired parameters at the moment of take off. We also wanted to check if the range of upper body motion is a determinant in the efficiency of the spike consisting in a high striking point and a remakable hitting force.

Material and methods: The video footage was obtained from 6 players of “U” Timisoara’s volleyball team and 6 international players. For the analysis and processing of the footage the program Kinovea was used and the following parameters were assessed: striking speed(m/s), range of motion (cm and °), flexion between arm and forearm, angle of arm with the vertical at contact, movement speed for the first, second and third approach steps.

Results: The international subjects had a 12 cm longer path of the hand in striking motion. Given the shorter segments of “U” Timisoara’s players, they compensate by having a 2° larger range of motion, above the elite players. We recorded diferent angles of the spiking arm with the vertical for the 2 groups, namely a mean of 24.5° for the elite players and just 15° for the players of “U” Timisoara. These aspects lead to a striking speed 3m/s higher for the international spikers compared to ”U” Timisoara sportsmen. Having measured a uniformly accelerated approach for the international subjects, “U” Timisoara’s players don’t respond to the same requirement with close values of the second and third step of approach.

Key words: analysis, technical execution, efficiency, performance
