The research aims to uncover the following: - The effect of rebound exercises using the sand sphere on a number of physical variables for the football players.

- The effect of rebound exercises using the water sphere on a number of physical variables for football players.

- The significance of the statistical differences in the sand and water media between the two experimental research groups in the post tests.

The researcher used the experimental method for its suitability with the nature of the research.

The experiment was carried out on a sample of the (24) players of the AL-Muthanna Sports Forum of Football, who were between (17- 19) years old, and they were chosen deliberately and divided randomly in to two groups (8) players for each group.

A group, and the researchers concluded the following: The creation of the training curriculum that used the rebound exercises and that was implemented by the two experimental groups, has a positive effect on the development of all physical characteristics of football under consideration.

The first experimental group (the water sphere), which used rebound exercises, outperformed the second experimental group (the sandy sphere), which used the same rebound exercises in physical characteristics (agility, velocity elongation).

The first experimental group (the water medium), which used rebound exercises, outperformed the second experimental group (the sandy sphere), which used the same rebound exercises in physical characteristics (transitional velocity, explosive strength of the leg muscles, the characteristic strength of velocity for the muscles of the legs, and elongation of strength for the two legs), but they did not reach the moral level.
