الملخص EN

The aims of study are to investigate : a.

Effect of aerobic Stress on malondialdehyde and its antioxidants.

b.

The relation between malondialdehyde and its antioxidants with lactic acid level in.

Assumptions of the study: v Existence of a significant difference between malondialdehyde and its antioxidants before and after aerobic Stress.

v Presence of a significant relation between malondialdehyde and its antioxidants with lactic acid level.

The samples of blood were collected from 20.

The studied parameters were malondialdehyde, glutathione, superoxidase enzyme, vitamin E and lactic acid.

The parameters were checked before and after effort.

The aerobic Stress was running for 1.5miles distance.

The data were statistically treated using SPSS program ( version17 ).

The following results were obtained : 1.

The concentration of malondialdehyde, glutathione, superoxidase enzyme and vitamin E significantly different before and after Stress.

2.

The existence of direct relation between concentrations of lactic acid and vitamin E after aerobic effort.

3.

No significant relation was found between lactic acid with malondialdehyde, glutathione and superoxidase enzyme beyond aerobic stress The researchers suggested that : 1-It is necessary to check malondialdehyde and its antioxidants to know the healthy state of players.

2-More studies performed using different stress.

3-The studies expand to cover other sport activities and for both sex.

4-Increasing number of samples in future studies.
