The training program consisted of three days sessions per week for (8) weeks The vertical jump test was used to measure the vertical jump distance and the Lewis Formula was applied to mesure the vertical jump power.

The results revealed that the first experimental group produced significant improvement in all the study variables. As for the second group, the results showed significant improvement in vertical jump distance while there were no significant statistical differences regarding power.
