The aim of the research is to find out: 1- The effect of smart training on a number of physical variables of the football players of the experimental group. 2- The effect of traditional training on a number of physical variables of the football players of the control group. 3- The statistically significant differences in a number of physical variables for football players between the two post tests for the two groups (experimental and control). The researcher hypothesized that: 1- There are statistically significant differences in a number of physical variables for football players between the pre and post tests of the experimental group. 2- There are statistically significant differences in a number of physical variables for football players between the pre and post tests of the control group. 3- There are statistically significant differences in some of the physical variables for football players between the two post tests for the two groups (experimental and control). The researcher used the experimental method for its relevance to the nature of the research. The research community was deliberately determined from the youth players of the Mosul Sports Club in football for the sports season (2020-2021). It consisted of (40) players, (24) players were selected as the research sample. By following the random selection method using lottery, the sample was divided into two groups: experimental and control with (12) players for each group. The following statistical methods were used: (percentage, arithmetic mean, standard deviation, (T) test for linked and independent samples, simple correlation coefficient (Pearson), mode, skew coefficient) and the statistical bag (SPSS) was used to process the data. The researchers concluded that: 1- The training design for smart training implemented by the experimental group made a significant development in some physical variables which are (strength characterized by speed of the legs, explosive power of the legs, maximum transitional speed, motor response speed, speed length of the legs, flexibility, compatibility) with the exception of the adjective of elongation that did not reach the moral level. 2- The training design for the trainer, which was implemented by the control group, made a significant development in the physical variables (the explosive power of the legs, maximum transitional speed, flexibility). 3-The experimental group that used smart training in the post-test outperformed the control group that adopted the trainer’s training in the physical variables (strength characterized by speed of the legs, speed of motor response, speed length of the legs, agility, compatibility). After identifying the scientific conclusions related to the topic of the research, the researchers recommend the following: 1- Paying attention to smart training when developing training designs for youth teams, as the results of the research showed the development of physical attributes. 2- Paying attention to special physical qualities, and comprehensive practical training by football coaches. 3- Applying smart training to other age groups, such as the cubs and juniors' category, to show its impact on the development events of these groups. 4- Applying smart training with other exercises to determine their impact and importance for football players.
