AU - لطف الله، سراب أكرم. AB - This research has included five sections: Part One included the importance of research. The research problem was that coaches often have difficulties to choose the size, kinds and intensity of exercises training and the necessary need to develop the capacity aerobic and anaerobic accurately, and according to right percentage, and should not be extended the training to develop system at expense of other, therefore skills training should be based on a broad base of aerobic and anaerobic endurance to bear the load of game or possibly tournament. The aims of the research were, measuring level of aerobic and anaerobic efficiency, and performing level of skills of serve and spike, the second goal was to identify the relation size between each of anaerobic and anaerobic efficiency level when performing serve and spike skills. The researcher discussed three hypotheses, and used descriptive method in procedures, described the research sample, equipment and tools that used, and the tests conducted. The researcher conclusions are: there is significant correlation between aerobic and anaerobic efficiency and research variables, and sample search had low level of anaerobic efficiency. The recommendations are: the need to focus on all kinds of aerobic exercises to develop explosive movements, and muscular endurance and the continuing blended between aerobic and anaerobic exercise.
