The current state of physical inactivity of people can be traced back to the people who have been denied their fundamental human right to physical education and participation in school sports (PES). Growing up without the fundamental human right to free movement and participation in sports activities enabled students to stay physically inactive. The purpose of this study was to explore what is currently known about the role of PES in all areas of human development and SDGs and to raise awareness about PES, which has been shown to be on the decline. To increase the study’s overall efficacy, an external desk research approach was employed to gather relevant information published online: reports, policies, charters, recommendations, and other relevant articles from various electronic databases and websites of international organizations responsible for PES, culture, and health. PES benefits are discussed in all domains of human development, including physical and mental health, cognitive, psychosocial, and moral benefits. Contrary to its importance to human growth as a whole, PES has been sidelined since the end of the twentieth century. An awareness of the subject of PES has thus been raised as a backbone of the entire community in the twenty-first century, so as to translate the promises and policies of PES into realities and practices.
