Abstract

The research aims to:
1-Prepare jump strength exercises in two different environment to develop arms and arms blast power on some physiology indicators and accurately perform the service and crush volleyball skills.
2- The introduction of the impact of high strength exercises in different environments to develop the force of the explosion and the arms on some indicators of physiology and the accuracy of the performance of service skills and crushing of volleyball.
3-Introducing the effect of pressure strength in two different environments on the accuracy of the performance skills of the service and crushing the volleyball.
4-Introduction of differences between the experimental groups in the subsequent tests on the strength of the explosion of arms and legs and some of the physiology and the accuracy of the performance skills of service and crushing volleyball.
The research used the experimental design of two groups with pre and post test tests. The research sample is 12 players from a specialized school. They were divided into two groups. One of them trained on the ground and the other group trained on the water. The proposed program included 38 units. The program has been developed in a land and water environment.
The research concluded that:
*Bouncing power has a positive effect on arms and legs force explosion.
*Bouncing power in the water has a positive effect on the legs and arms burst force
