The statistical coefficients used were (arithmetic mean - standard deviation - correlation coefficient - t-test). The results of the study resulted in statistically significant differences at the level of (0.05)between the pre- and post-measurements in favor of the post-measurement in both the physical tests and the effectiveness of the young boxers’ offensive performance - under study - which the researcher attributes to the use of integrative functional exercises in the proposed training program, and the researcher recommends There is a need to move toward using integrated functional exercises in boxing training programs ــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــ Assistant Professor, Department of Theories and Applications of Competitions and Individual Sports - Faculty of Physical Education for mens - Zagazig University
