Vision Emerging from the vibrant discussions of the "Future Matters" specialist seminar, this special issue, titled "Architects of Change: Co-Designing the Next Generation of Physical Education," moves beyond critique to construction. It challenges the Physical Education (PE) community to shift its role from observers of systemic problems to active designers of systemic solutions. This collection is a testament to a new paradigm in our field: one where researchers, practitioners, and students collaborate as partners in co-designing a more equitable, inclusive, and socially sustainable future for all. Scope and Focus For too long, conversations about the future of PE have been dominated by retrofitted solutions to address deep-seated inequities. This special issue forges a new path. We are not just identifying problems; we are showcasing the blueprints for a better future. The core of this issue is built on the principles of social sustainability, focusing on how PE can become a space that actively fosters well-being, equity, and inclusion for every student, particularly those who have been systematically marginalized. This issue addresses critical questions facing the future of our field: •How can we move from simply identifying exclusion to actively designing for inclusion? •What does a co-construction process—involving students, teachers, and researchers—look like in practice? •How can we create PE environments that are not only physically active but also socially and emotionally nurturing? Content and Format In line with this forward-looking vision, the special issue features a collection of short communications (2,000–2,500 words). These are not traditional research articles but rather dynamic snapshots of innovation in progress. Contributors were invited to share the concepts, ideas, and projects that are poised to shape the future of PE. The submissions may include early empirical data, but their primary aim is to provide readers with a glimpse into the next generation of thought and practice in our field. Ultimately, "Architects of Change" serves as both a manifesto and a practical guide. It is a call to action for the entire PE community to embrace a collaborative, evidence-based, and design-oriented approach to building the future we want to see—a future where PE is designed by many, for all.
