Abstract

The Effect of various effort Kinds made by man on his functional devices is not a secret any more. This comes from the precious efforts made by many scientists for many decades. Whenever modern technologies measuring various physiological appear, researchers use them to recap other phenomena and discover new physiological phenomena in the human body. Exercise lead to make changes in blood ingrediants and the respiratory device as it is the case with any other body organ and the changes are of two kinds: (temporal i.e. changes that occur temporarily as a response to physioloyical effort and turn back in rest) and relatively continuous ( the changes that happen in these variables due to regularity in practice for a certain time which lead to adaptation of blood for doing exercise).


The research aims at:
- Reveal the effect of Graded aerobic effort on some lung ventilation variables (number of breathing times, means of normal breathing, ventilation).
- Reveal the effect of Graded aerobic effort on some blood variables (red and white blood cells, hemoglobine).
The researcher hypothesized the existence of statistically significant differences in blood ingredients (red and white blood cells, hemoglobine), and ventilation variables (number of breathing times, volume of breather air, ventilation), before and after doing maximum physiological and aerial effort .
The researcher used the descriptive method due to its appropriateness. The sample consisted of (11) students aging (18-21 years) representing first year of Physical Education Department- College of Basic Education/ University of Mosul, and the researchers used testing and measuring as tools to collect data.
The researcher used the following statistical means:
(ratio, mathematical means, standard deviation, variance factor , t-test for two related groups).
After treating data statistically, the researcher concluded:
• Graded aerobic effort had (tangible increase) tangible effect on lung ventilation variables.
• Graded aerobic effort had tangible effect (tangible increase) in some blood ingredient variables Compared to rest time and in faver of post test.
The researcher recommended:
• The necessity of doing lab tests of candidates of the department of Physical Education to by used in the process of selection.
• Open a record for every student to keep his physiological, functional and chemical measurements to evaluate the health condition and his progress in every academic stage.
• Make a similar study with the same variables but on female students.
