"Thirty-four percent of the student-athletes involved in the Wisconsin study specialized in one sport, with females (41%) more likely to specialize than males (28%). Soccer had the highest level of specialization for both males (45%) and females (49%). After soccer, the rate of specialization for females was highest for softball (45%), volleyball (43%) and basketball (37%). The top specialization sports for males after soccer were basketball (37%), tennis (33%) and wrestling (29%). The sports with lowest levels of specialization were football (16%) for boys and track and field (15%) for girls."
I thought the above quote breakdown was enlightening.
If I read correctly, injury rates to legs is about twice as high if you specialize in one sport.
And then there is the basketball argument I hear..."Don't play football and jeopardize your basketball future by getting hurt."
Need more kids golfing as a second or third sport.
