For more than 20 years, I have been conducting research on the relationship between physical activity and cognitive development. Based on the body of research accumulated to date, I believe it is a scientifically established fact that physical activity promotes cognitive development in children¹ ). What has become clear from this body of research is that the specific type of physical activity is not the essential issue; rather, what matters is having as many opportunities as possible to be physically active and maintaining that activity over time. The key to sustaining physical activity is the experience of finding it enjoyable.
On the other hand, many current sports programs tend to place an emphasis on improving technique and athletic performance. Of course, improving technique and athletic performance can sometimes be enjoyable in and of itself, and we do not deny that. However, particularly during early childhood and childhood, we believe that experiences that make children think, “I want to do this more” or “I want to do this again”—rather than the improvement of technique and athletic performance itself—form the foundation for lifelong exercise habits 2).In this regard, Lii Sports’ approach—which focuses on the enjoyment of physical activity—is truly unique, and I feel it captures the essence of fostering lifelong exercise habits.
Furthermore, since there is overlap between the brain regions that support cognitive function and social skills, physical activity may contribute not only to cognitive function but also to the improvement of social skills³). Lii Sports’ approach—which prioritizes fun while simultaneously fostering the development of communication and interpersonal relationships—supports children’s multifaceted growth. As a new model that transcends the traditional framework of physical education classes, it suggests a new direction for future physical activity programs.
