The manuscript “Plasma Somatomedin-C in 8- to 10-Year-Old Swimmers” by Denison and Ben-Ezra published in the first issue of Pediatric Exercise Science in 1989 was among the first to address the relationship between growth, the growth hormone (GH)/insulin like growth factor-1 (IGF-1) axis, and exercise. Since their pioneering article, this topic has become of great interest to pediatricians and pediatric exercise researchers, and today our understanding of the effects of exercise training on the growth axis during childhood and puberty, on differences between systemic and local (i.e., muscle) responses to exercise, and our ability to use these responses to assist the adolescent competitive athlete in the evaluation of the training load have markedly improved. The aim of the present review is to summarize our current knowledge on this topic.

Engaging communication of complex scientific concepts with the general public requires more than simplification. Compelling, relevant, and timely points of linkage between scientific concepts and the experiences and interests of the general public are needed. Pop-culture icons such as superheroes can represent excellent opportunities for exploring scientific concepts in a mental “landscape” that is comfortable and familiar. Using an established icon as a familiar frame of reference, complex scientific concepts can then be discussed in a more accessible manner. In this framework, scientists and the general public use the cultural icon to occupy a commonly known performance characteristic. For example, Batman represents a globally recognized icon who represents the ultimate response to exercise and training. The physiology that underlies Batman's abilities can then be discussed and explored using real scientific examples that highlight truths and fallacies contained in the presentation of pop-culture icons. Critically, it is not important whether the popular representation of the icon shows correct science because the real science can be revealed in discussing the character through this lens. Scientists and educators can then use these icons as foils for exploring complex ideas in a context that is less threatening and more comfortable for the target audience. A “middle-ground hypothesis” for science communication is proposed in which pop-culture icons are used to exploring scientific concepts in a bridging mental landscape that is comfortable and familiar. This approach is encouraged for communication with all nonscientists regardless of age.
