Abstract: Based on the theory of social criticism in the era of technology, this paper discusses the cultural crisis in the childhood world under the proliferation of electronic media, as well as the philosophical path of physical education to the rescue of childhood. Childhood is a life time different from adulthood, but electronic media are closing the gap between these two, making children exposed to adulthood too early, and causing the fading and even dying out of childhood. Childhood is being influenced by the electronic media information blockage, image flooding, capital manipulation, entertainment suffocation, education discipline and static locking. Childhood is being filled with choking fear. This directly results in the entrapment of children in front of the electronic screen, leaving their body in a static one-way bind. Physical education is not only a means to recover, remedy and maintain the body dynamics, but also a practical way to solve the childhood crisis. The humanism, time memory, image landscape, practice connotation and life psalm lying in the physical education are the dynamic salvation of childhood, freeing the childhood from the prison of electronic media, and eventually bring them back on the theoretical path of "whole person development" and giving children the integrity of life. Physical education retains childhood, creates lively, robust and vigorous dynamic life.

Key words: childhood, children, physical education, life, body, technology, philosophy
