The research aimed to develop proposed training units using Pilates training for junior speedball stage (17) years and to know its effect on some physiological variables (pulse rate immediately after exertion - lactic acid before exertion and immediately after exertion - maximum oxygen consumption) and the digital level of solitary play (playing with one racket with the right hand - playing with one racket with the left hand - playing with two front rackets - playing with two rear rackets) for junior speedball stage (17) years, and the researcher used the experimental approach on a sample of (10) juniors speedball stage (17) years, and research tools: physiological measurements - Pilates training program. Among the most important results: 1- The proposed training program using Pilates training has a positive effect statistically at the level of (0.05) on some physiological variables, while it does not statistically affect the pulse rate immediately after the effort for junior speedball stage (17) years. 2- The proposed training program using Pilates training has a positive effect statistically at the level of (0.05) at the digital level of solitary play for junior speedball stage (17) years. 3- The existence of improvement rates in the dimensional measurement of the tribal members of the basic research sample in some physiological variables for junior speedball stage (17) years ranged between (2.56%: 22.02%). 4- The existence of improvement rates in the dimensional measurement of the tribal members of the basic research sample in the digital level of solitary play for junior speedball stage (17) years ranged between (3.83%: 5.00%).
