Consisted research presented and its significance, which lies in the identification of responses and effects occurring in some variables respiratory enzymes when football players through stress tests tests the research problem Vttgly in the use of stress tests Alibd faith by the coaches either Kachtbarat periodically or as units training without knowing functional effects and responses to some variables and respiratory enzymes in order to know the importance of these tests in the efficiency of functional players The objectives of the research were as follows 1- identify the impact of stress tests (private and public) in some variables and respiratory enzymes in football players 2- Identifying the differences between the tests and measurements after voltage endurance test for the public and private sectors in some variables and respiratory enzymes in football players Researcher and put the following hypotheses 1- there were significant differences in some variables and respiratory enzymes under consideration to measure before and after the stress tests and for dimensional measurement 2- there were significant differences between the tests and measurements after the effort to test the endurance and test your endurance in some variables and respiratory enzymes under discussion The research methodology and procedures field researcher used a pilot user as well as the description of the sample and the tools used, as well as the tests and measurements used The display, analysis and discussion of the results / display and analyze the results by tables And was the most important findings of the researcher is 1- There are significant differences in some variables respiratory enzymes under discussion between the two measurements (before and after the effort) to test endurance private and public only enzyme GPX in endurance test private and enzymatically GPT, GOT in endurance test year (Cooper) and that did not register significant differences 2- and significant differences between the tests and measurements (after voltage) to test endurance private and public in all variables respiratory enzymes under discussion and for endurance test your except reserve inspiratory RV and enzyme GPT who did not Asgela significant differences, as well as the enzyme GPX, which was Frogah for stress testing year.
