The researcher chose to investigate adaptation, one of the axis that drives this process, in order to accurately explore it scientifically. Psychological understanding and how it relates to the competitive aggression issue, and examining that connection to create suitable remedies. In addition, the study attempts to establish benchmarks for competitive aggression and psychological adjustment for football players from first division southern clubs, as well as to determine how these benchmarks relate to one another then extract the levels and standards for the measurements.
