Study: Single-Sport Athletes Injured More
November 3, 2016
A study conducted by the University of Wisconsin School of Medicine and Public Health and funded by the National Federation of State High School Associations (NFHS) Foundation revealed that high school athletes who specialize in a single sport sustain lower-extremity injuries at significantly higher rates than athletes who do not specialize in one sport.
The study was conducted throughout the 2015-16 school year at 29 high schools in Wisconsin involving more than 1,500 student-athletes equally divided between male and female participants. The schools involved in the study represented a mixture of rural (14), suburban (12) and urban (3) areas, and enrollments were equally diverse with 10 small schools (less than 500 students), 10 medium schools (501-1,000 students) and nine large schools (more than 1,000 students).
Athletes who specialized in one sport were twice as likely to report previously sustaining a lower-extremity injury while participating in sports (46%) than athletes who did not specialize (24%). In addition, specialized athletes sustained 60 percent more new lower-extremity injuries during the study than athletes who did not specialize. Lower-extremity injuries were defined as any acute, gradual, recurrent or repetitive-use injury to the lower musculoskeletal system.
“While we have long believed that sport specialization by high school athletes leads to an increased risk of overuse injury, this study confirms those beliefs about the potential risks of sport specialization,” said Bob Gardner, NFHS executive director. “Coaches, parents and student-athletes need to be aware of the injury risks involved with an overemphasis in a single sport.”
Among those who reported previously sustaining a lower-extremity injury, the areas of the body injured most often were the ankle (43%) and knee (23%). The most common types of previous injuries were ligament sprains (51%) and muscle/tendon strains (20%).
New injuries during the year-long study occurred most often to the ankle (34%), knee (25%) and upper leg (13%), with the most common injuries being ligament sprains (41%), muscle/tendon strains (25%) and tendonitis (20%).
In addition, specialized athletes were twice as likely to sustain a gradual onset/repetitive-use injury than athletes who did not specialize, and those who specialized were more likely to sustain an injury even when controlling for gender, grade, previous injury status and sport.
Thirty-four (34) 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 study, which was directed by Timothy McGuine, Ph.D., ATC, of the University of Wisconsin, also documented the effects of concurrent sport participation (participating in an interscholastic sport while simultaneously participating in an out-of-school club sport), which indicated further risk of athletes sustaining lower-extremity injuries.
Almost 50 percent of the student-athletes involved in the survey indicated they participated on a club team outside the school setting, and 15 percent of those individuals did so while simultaneously competing in a different sport within the school. Seventeen (17) percent of the student-athletes indicated that they took part in 60 or more primary sport competitions (school and club) in a single year. Among those student-athletes in this group who sustained new lower-extremity injuries during the year, 27 percent were athletes who specialized in one sport.
The student-athletes involved in the study were deemed “specialized” if they answered “yes” to at least four of the following six questions: 1) Do you train more than 75 percent of the time in your primary sport?; 2) Do you train to improve skill and miss time with friends as a result?; 3) Have you quit another sport to focus on one sport?; 4) Do you consider your primary sport more important than your other sports?; 5) Do you regularly travel out of state for your primary sport?; 6) Do you train more than eight months a year in your primary sport?
Although some sports (field hockey, lacrosse) are not offered in Wisconsin and were not included in the study, the study concluded that since specialization increased the risk of lower-extremity injuries in sports involved in the survey it would also likely increase the risk of injuries in sports that were not a part of the study.
Pay-to-Play Use Hovers at 50 percent

Half of MHSAA member high schools continued to assess sports participation fees during the 2018-19 school year, according to a survey that has measured the prevalence of charging students to help fund interscholastic athletics annually over the last 15 years.
Of the 604 schools which responded to the 2018-19 survey, exactly half – 302 – assessed a participation fee, while 302 did not during the past school year. This year’s survey results are in line with those of the last two schools years, which saw 49.7 percent of schools charging participation fees for 2016-17 and 49 percent in 2017-18. For the purposes of the survey, a participation fee was anything $20 or more regardless of what the school called the charge (registration fee, insurance fee, transportation fee, etc.).
The MHSAA conducted its first participation fee survey during the 2003-04 school year, when 24 percent of responding schools reported they charged fees. The percentage of member schools charging fees crossed 50 percent in 2010-11 and reached a high of 56.6 percent in 2013-14 before falling back below 50 percent in 2016-17.
A record number of member high schools responded to the survey for the second straight year – 81 percent of the MHSAA’s 750 member schools provided data for 2018-19. Class A schools again remained the largest group charging fees, with 69 percent of respondents doing so. Class B and Class C schools followed, both with 48 percent charging fees, and Class D schools also remained in line with the previous year with 35 percent charging for participation.
Charging a standardized fee for each team on which a student-athlete participates – regardless of the number of teams – remains the most popular method among schools assessing fees, with that rate at 45 percent of schools. Schools charging a one-time standardized fee per student-athlete remained constant at 28 percent. A slight uptick was seen in the percentage of schools assessing fees based on tiers of the number of sports a student-athlete plays (for example, charging a larger fee for the first team and less for additional sports), with 20 percent of responding schools charging in this way compared to 15 percent a year ago.
The amounts of most fees remained consistent or similar as well during 2018-19. The median annual maximum fee per student of $150 and the median annual maximum family fee of $300 both remained constant for at least the fifth straight year, while the median fee assessed by schools that charge student-athletes once per year held steady at $125 for the third straight school year. The median per-team fee increased slightly, $5, to $80 for 2018-19.
The survey for 2018-19 and surveys from previous years can be found on the MHSAA Website.
The MHSAA is a private, not-for-profit corporation of voluntary membership by more than 1,500 public and private senior high schools and junior high/middle schools which exists to develop common rules for athletic eligibility and competition. No government funds or tax dollars support the MHSAA, which was the first such association nationally to not accept membership dues or tournament entry fees from schools. Member schools which enforce these rules are permitted to participate in MHSAA tournaments, which attract more than 1.4 million spectators each year.
