The effect of physical skill exercise by Sycle style and by interval training on explosive power & on serve-smash skills

The aims of the study: - Significant statistical differences between pre and post tests of the system work (15) and comfort (30) seconds in the explosive power of the female volleyball players for the two experimental and control groups. - Significant statistical differences between pre and post tests of the system work (15) and comfort (30) seconds in the serve and smash my skills to the female volleyball players in the two experimental and control groups. The researcher used the experimental approach to the nature of the research, and implemented curriculum on a sample of players elected Qrhqosh volleyball, who are (16 player), and divided into two groups tested and the control group by (8 players) in each group, and included research procedures designed six exercises applied in the curriculum, with doing three experiments reconnaissance, before beginning the curriculum has been testing the tribal physical and skill, and it took the implementation of the curriculum of eight weeks, with three training modules in the course of small and finally testing a posteriori physical and skill, the researcher reached the following conclusions: Made physical exercise skills in a cycle-style low-intensity interval training system action (15 sec) and comfort (30 sec) has evolved in the physical attributes of selected. In light of the findings, the researcher recommended the following: the possibility of using physical exercise skills trained in the rest of the sporting events (football, basketball) to positively contribute to the development of some physical attributes and skills.
