Abstract:The physiology as children and the nascents works in a high degree of complication, because it has a special basics dedicated to the changes as the physiques and all biological appearances that everyone can think about.

And also the specifying physiological factors as the mater cortex during the childhood duration which is being in a continuous state as growth and development.

And the functional state as the children is dynamic So, the significance of this research lays on comparing the direct response of the airy effort canalled in some heart change values and blood dynamics, and to stand on the values of these changes in the resting condition and after the airy effort for the young aged in (11-15) years old of a good health state .

Research objectives: • discover the values of the cardiac outpput and variant through resting for children (11-15).• discover the values cardiac outpput and variant after an airy effort for children (11-15).

Research hypothesis: • morale varaities before and after the airy test is existed for children (11-15).

• morale varieties before and after the airy test is existed among children (11-15).

The researcher uses testing and measuring as they described as ways of gathering information from the samples of the study which consists of : (Bruce test, physical measurements and functional changes).

The following calculating means is used: (arithmetical mean, standard deviation, analysis of variance and lsd test).

And in the light of presenting and discussing the results, the following conclusions is extracted : from the preceding tests (during resting) that all the cardiac outpput and variant of the samples was in their normal averages.The three entireties of the research share the existence of the airy effort impact in measuring of the cardiac outpput and variant.

At Comparison between the values of the cardiac outpput and variant in resting It turns out There are significant in Variables (HR , SV) Where the highest value was (HR)about ages (11) and the highest value was (sv) about ages(15).
