Abstract EN

The study aimed to identify the effect of two warm-up protocols in the distance and the speed of volleyball players vertical jump.

To achieve this goal we used the warm-up protocols (jump without warm-up, stretching for (10) minutes then warm-up for (5) minutes, (10) minutes' warm-up then (5) minutes stretching), applied to a sample of (5) players were chosen intentionally.

vertical jump test was used to measure the distance of the jump ability, analysis software (kinova) and the equation of speed in the collection of the information necessary in addition to the physical variables such as Length and Length with extended arm, body mass,age.

The best attempts were taken to players to detect differences in the distance and the speed of the vertical jump to the players.

Results indicated the presence of the stylistic differences between the warm-up for the benefit of the warm-up then stretching.

We recommend the need to use the warm-up exercises then stretching exercises in the vertical jump exercises.
