Mary Elizabeth Dallas’s article, “Injury Risk May Rise When Kids Play Just One Sport” (March 17, 2017) asserts that focusing on one sport when children are 12 years old or under increases their risk of injury. Dallas supports this by using quotes from the researchers of the study that found this to be true, describes the study (the timeline and sample size), and compares the injuries in children above and below the age of 12 and how many sports they played. The purpose was to summarize a study done by Emory University School of Medicine in order to convey the findings of the study easily to readers who may have trouble understanding scientific jargon. By doing so, the author disputes an idea widely believed – that playing more sports increasing injury.
