The current research aims to design a recommended training program using qualitative exercises and to identify its effects on improving some tactical patterns and complex technical performances for junior soccer players. The researcher used the experimental (one-group design) approach with pre- and post-measurements. The research sample was purposefully selected from junior soccer players (less than 19 years old) from Qualioub Youth Center (Qualiubia Football Zone) during the 2023-2024 season. The research community included (33) junior players, out of which (3) were excluded for injury and (10) were recruited for the pilot sample. The main sample included (20) junior players. Results indicated that:

• The recommended qualitative training program induced statistically significant differences between the pre-and post-measurements of tactical patterns as phases for building up attack for both back defender positions in favor of post-measurements.

• The recommended qualitative training program induced statistically significant differences between the pre-and post-measurements of complex technical performance as phases for building up attack for both back defender positions in favor of post-measurements.

• Qualitative exercises had positive effects on improving some tactical patterns and complex technical performances of junior soccer players less than 19 years old.
