A study involving Wisconsin high school athletes and funded by the National Federation of State High School Assns. concluded that high school athletes who specialize in one sport sustain "lower-extremity injuries at significantly higher rates than athletes who do not specialize in one sport."
The study was conducted by the University of Wisconsin School of Medicine and Public Health during the 2015-16 school year at 29 high schools and involved more than 1,500 male and female athletes.
Here's the link to the study results.
