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.
MHSAA's Roberts to Retire in August

For 32 years, Jack Roberts has served as much more than a caretaker of the Michigan High School Athletic Association.
In announcing his retirement Tuesday, he called working for 1,500 schools and hundreds of thousands of student-athletes over three decades his "purpose."
John E. “Jack” Roberts, who has served as executive director of the MHSAA since the fall of 1986, will retire in August.
Roberts will conclude his tenure as the second-longest serving full-time executive director during the MHSAA’s 94-year history. He is the fourth person to serve that leadership role full time, following Charles E. Forsythe (1931-42, 1945-68), Allen W. Bush (1968-78) and Vern L. Norris (1978-86). Roberts currently is also the nation’s longest-serving executive director of a state high school athletic association.
The MHSAA has enjoyed continued growth under Roberts’ guidance, particularly in the number of Michigan high school students participating in athletics and in the number of MHSAA-sponsored tournament sports available to them.
The Association also has made unprecedented advances in providing for the health and safety of athletes and promoting sportsmanship and the values of educational athletics and while working to preserve competitive equity for its more than 1,500 member high school and junior high/middle schools.
“I don’t think anybody could have been luckier than I to enjoy their work so much and to enjoy the people he worked with so much,” Roberts said. “It has been a blessing to be able to bring my passions to work every day and be able to act on my convictions. I don’t think anybody could ever feel more called to a job than I did."
Under Roberts’ leadership, overall participation in high school athletics in Michigan has increased 10 percent, and the MHSAA has added more than 200 schools in increasing its membership by more than 15 percent at the high school and junior high/middle school levels combined. Most recently, in 2016, 6th-graders were allowed to compete for member schools for the first time as a push was made to increase junior high/middle school membership and serve the state’s students earlier in their athletic careers.
His tenure has seen the addition of girls competitive cheer (1994), girls & boys bowling (2004) and girls & boys lacrosse (2005) to the tournament sport lineup, the creation of separate wrestling tournament to determine champions by team format (1988) and 8-player football (2010, first playoffs 2011) as many small schools across the state began having trouble fielding 11-player teams because of enrollment and population decreases. Meanwhile, also under his leadership, the 11-player Football Playoffs expanded, doubling to 256 teams in 1999.
A number of key rules changes came under Roberts’ watch and direction, including the addition of opportunities for multiple schools to create cooperative teams in sports where participation is lagging, as well as the creation of down time and dead periods (2006) to ease pressure for year-round activity. A comprehensive sportsmanship package enacted in 1996 set a statewide tone for appropriate behavior and perspective that continues to make an impact today.
But the most significant and arguably lasting work influenced by Roberts came on topics not related to specific sports or competition. The MHSAA has led nationally in concussion care with its first programming in 2000 and return-to-play protocols enacted in 2010, and with concussion pilot testing, mandated reporting and insurance for those who suffer head injuries rolled out in 2015.
A heat management policy and CPR requirements for coaches were introduced in 2013. The first program for coaches education was launched in 1987 and evolved into the Coaches Advancement Program that is now required for all newly-hired varsity head coaches, and all coaches (head or assistant) at all high school levels (varsity and subvarsity) are now required to take annual rules/health meetings.
The Women in Sports Leadership Conference was created in 1989 and remains the first, largest and longest-running program of its type in the country, regularly drawing upwards of 500 participants. The first of now-annual statewide Athletic Director In-Service Programs was conducted in 1992, and the MHSAA’s website – MHSAA.com – was launched in 1997. That same year the first of the now-annual Sportsmanship Summits was held, and Michigan remains a national leader in student services thanks to a variety of programs that have been introduced over the last three decades.
“We have accomplished a great deal over 32 years, but there is very much more to do – and it will always be that way,” Roberts said. “People ask me if I have any regrets, and I don’t have many. But two come to mind right now.
“I regret that I didn’t spend more time writing notes to the folks I’ve been serving at the local level who work so hard delivering the program every day, every week, every season, every year to the young people that we serve. I wish I’d done more of that – that encouraging word to people in the trenches doing the work.
“And I suppose the second regret is that in spite of everything that we’ve done, there’s still a lot more to do to keep school sports as safe, sane and sportsmanlike as it ought to be – as it must be for schools to continue to sponsor these programs. You see, school sports done right brings help and hope to parents and to schools who are trying as hard as they can to raise up and educate kids in very, very scary times. School sports helps parents and helps schools bring stability and engagement into young people’s lives that can provide them life lessons and turn some good athletes into great citizens down the road.”
Roberts privately made the decision to retire during May 2017. But even as he has prepared for his retirement this summer, he’s catalyzed a Multi-Sport Participation Task Force charged with promoting the benefits of playing more than one sport and led the facilitating of statewide discussion on a sport-based transfer rule proposal that will come before the MHSAA's Representative Council in May.
In addition to his work specifically in Michigan, Roberts has carried significant influence at the national level. With his retirement, he also will be leaving the National Federation of State High School Associations (NFHS) Board of Directors. He led the creation of the NFHS Network for video productions in 2012 and is finishing an extended term as that board’s chairperson. He also has served on the board of directors of the National Association of Sports Officials (NASO).
Roberts previously served as an assistant director for the National Federation from 1973-80. He came to the MHSAA in 1986 from the Fellowship of Christian Athletes, which he served as executive vice president. During the last 45 years, Roberts has spoken to education, business and civic groups in nearly every state and five Canadian provinces and continues to be hailed as one of the nation’s most articulate advocates for educational athletics.
"We have always felt that we had the best executive director in the United States. What he's done for interscholastic athletics in Michigan is incredible," said MHSAA Representative Council President Scott Grimes, who serves as assistant superintendent of human services for Grand Haven Area Public Schools.
"Jack has always had student-athletes' best interests in mind when making all decisions, and he's had tough decisions to make. We certainly will miss his leadership in our state."
In addition to his MHSAA work, Roberts has served as board president for the Refugee Development Center in Lansing for nine years and this year is the chair of the board of trustees for the Capital Regional Community Foundation. He is a 1970 graduate of Dartmouth College and taught English and coached football at high schools in Milwaukee and Denver before joining the NFHS staff. He and his wife Peggy reside in East Lansing, and his late father, John Roberts, served as the executive director of the Wisconsin Interscholastic Athletic Association (WIAA) from 1957-86.
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.
