الملخص EN

This study aimed to know the effect of using bliometric exercises (with one or - two feet) in some physical characteristics and basic skills for Professional football players in the two experimental groups and the differences in some physical characteristics and basic skills between both groups.

The procedures included designing a training course using bliometric exercises and applied on two experimental groups, the first group used bliometric exercises with one foot while the second yroup applied it with two feet after determining maximum in tensity (100%) for one and two feet.

The researchers used the experimental method due to its appropriateness.

The sample was chosen from Talaaffar football club intentionally and was divided in to two equal groups randomly.

Equivalence was achieved between both groups .

To achieve the aims of the research, the researcher put the following hypotheses: - There is a statistically significant difference in some physical features between pre-post tests for both groups.

- There is a of statistically significant difference in some basic skills between pre-post tests for both groups.

- There is a of statistically significant difference in some physical characteristics between both groups in a post tests .

- There is a of statistically significant difference in some basic skills between both groups in post tests .

The researchers came up with the following conclusions: - The bliometric exercises carried out by the first experimental group using one-foot resulted in moral development in characters of (elasticity, transational speed , speed distinguished force) in addition to (explosive power) but didn’t reach moral level .

- The bliometric exercises carried out by the second experimental group using two-feet made a moral development in all physical characters.

- The bliometric exercises made by the first experimental group one-foot madea moral development in skills ( head kick , control the ball, long pass) in addition to the development in skills ( rolling, close shoot ) but didn’t reach moral level .

- The bliometric exercises carried out by the second experimental group two-feet achieved a moral development in the skills of ( rolling, control of the ball) in addition to the development in the skills ( head kicking, close shoot, long pass) but didn’t reach moral level.

- The bliometric exercises made by the second experimental group two- feet surpassed posttest of the first experimental group in all physical features.

- The bliometric exercises made by the second experimental group (with two-feet) surpassed the post test of the first experimental group (with one foot) in all basic skills .

The researchers recommend: - The necessity of paying attention to bliometric exercises putting training courses due to their results in developing physical characters and basic skills.

- The possibility of applying this suggested training model on other age group juniors and amateurs due to its impact on developing these categories.

- Focus on using bliometric exercises with two feet rather than one feet according to the result obtained in this research.
