The current study aimed at identifying the statistical significances in some physical characteristics of lower limbs muscles of the two groups of the study; the experimental one which was subject to high Intensity jump exercises and the controlling one which was subject to the normal training program, through the results of the pre and post tests.

The research was executed on the scope of the study which was chosen intentionally representing the football team of young players in Alintisar School for the athletic semester 2008-2009 which consisted of 30 players.
