Small-Sided Games in Youth Football: Advancing Technical–Tactical Performance and Social Inclusion for Sustainable Development

Sport has long served as a powerful vehicle for promoting social inclusion, particularly among marginalized youth. Football, due to its global appeal and participatory nature, is uniquely positioned to bridge social divides while fostering technical and tactical development. This study explores the dual function of small-sided games (SSGs) in advancing both performance outcomes and inclusive dynamics within youth football contexts. Utilizing a longitudinal case study of a Romanian U14 team during the 2022–2023 season, we implemented a tailored SSG training program aimed at enhancing offensive play and team cohesion. Performance was assessed using key technical and tactical indicators, with data analyzed via SmartPLS structural equation modeling. Results demonstrated statistically significant improvements in several offensive and defensive metrics, including crosses, collective goal-scoring, and ball recovery actions. Importantly, the format of SSGs facilitated equitable participation, reinforcing inclusionary practices. The findings support the integration of SSGs not only as effective pedagogical tools for football training but also as mechanisms for fostering social development through sport. This study underscores the strategic potential of SSGs in aligning youth athletic training with broader educational and social inclusion objectives.
