Interesting article I looked up recently
“A separate 2016 study from Bell and his team found that 36% of high school athletes classified as highly specialized, training in one sport for more than eight months a year — and that those athletes were two to three times more likely to suffer a hip or knee injury.”
“Those who were highly specialized in one sport (at the exclusion of other sports) and played it year-round were at a significantly higher risk for serious overuse injuries, such as bone and cartilage injuries and ligament injuries. How much higher of a risk? About 125%.”
