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.
Jacques to Receive Forsythe Award for Local Leadership, Peninsula & Statewide Service

Serving as athletic director at Michigan’s northernmost high school, Calumet’s Sean Jacques has impacted student-athletes not only in his community, but across the Upper Peninsula and all the way to the state’s southern borders as a member of the Michigan High School Athletic Association’s Representative Council. To recognize his far-reaching contributions across several leadership roles, Jacques has been selected as the 2024 honoree for the MHSAA’s Charles E. Forsythe Lifetime Achievement Award.
The annual award is in its 47th year and named after former MHSAA Executive Director Charles E. Forsythe, the Association's first full-time and longest-serving chief executive. Forsythe Award recipients are selected each year by the MHSAA Representative Council, based on an individual's outstanding contributions to the interscholastic athletics community at the local, regional and statewide levels. Jacques will be honored during the MHSAA Girls Basketball Finals on March 23 at Michigan State University’s Breslin Center.
A 1985 graduate of Calumet, Jacques taught for one year at Lansing Everett before returning to his alma mater in 1992, when he began teaching primarily technology and metal shop until becoming the athletic director and an assistant principal in 2008. He served in those administrative roles through the end of the 2021-22 school year and currently is an instructor for the Calumet-Laurium-Keweenaw school district’s Upper Peninsula Virtual Academy.
During his tenure as athletic director, Calumet added junior varsity hockey, junior varsity and varsity softball, and varsity baseball, bowling and gymnastics teams. He led facility upgrades including the addition of a turf football field, new locker rooms and an additional gymnasium, creating a home not only for Copper Kings athletes and coaches but for those from all over the northern UP as Calumet is a frequent host of MHSAA District and Regional events plus Coaching Advancement Program (CAP) sessions.
Also under his direction, Calumet became the first Upper Peninsula school to join the MHSAA School Broadcast Program, and he created the high school’s Athletic Hall of Fame in 2012. In 2016, Calumet became the only Upper Peninsula school to earn the prestigious Michigan Exemplary Athletic Program honor from the Michigan Interscholastic Athletic Administrators Association (MIAAA).
“When I became athletic director, my goal was number one, we were going to run a classy program. We were going to do it right. We weren’t going to be lazy about anything, not take the easy road. I wanted to do right for the kids, the school district and the community,” Jacques said. “We went after a lot of different things. It’s very cliché, but we really did try to put kids first. Every decision we made, we always tried to make decisions with that in mind – what’s best for the kids – and worked hard to be innovative and try to run a quality, classy program.”
His impact hardly has been contained to the Keweenaw Peninsula. He served as president of both the Keweenaw Area Athletic Directors group and Upper Peninsula Athletic Directors Association from 2014-22, in addition to serving as commissioner for the Western Peninsula Athletic Conference from 2012-22 and the Great Lakes Hockey Conference from 2009-22. He began his tenure on the Upper Peninsula Athletic Committee in 2014, when he also was first elected to the MHSAA Representative Council as the delegate for Class C and D schools in the Upper Peninsula. He is serving on the MHSAA’s Audit and Finance Committee currently, and will conclude his tenure on Council in December.
Jacques also served as an MIAAA regional representative for more than a decade and was named Regional Athletic Director of the Year by the MIAAA in 2013 and 2016. The Upper Peninsula Athletic Directors Association named him its Upper Peninsula Athletic Director of the Year in 2019.
Jacques also currently is among eight mentors to new athletic administrators across the state as part of the MHSAA’s first-year AD Connection Program. In this role, Jacques directly works with 16 recently-hired athletic directors as they navigate the job’s many and various responsibilities.
“Sean Jacques brings knowledge of so many aspects of school sports, not only the work done day-to-day as an athletic director but as an innovator who developed an athletic department recognized and respected across the state,” MHSAA Executive Director Mark Uyl said. “His community, the Upper Peninsula and Michigan as a whole continue to benefit from his dedication and leadership – and we’re fortunate he’s sharing that expertise with the next generation of athletic directors as part of our mentorship program.”
Jacques has contributed nearly as significantly on the field of play. He has been an MHSAA registered official for 35 years, in hockey for the entirety and adding track & field in 1994-95 and cross country in 2009-10. He officiated at the MHSAA Hockey Finals in 2016 and has served as a board member for the Copper Country Hockey Officials Association, including as its scheduler for 14 years. He has 40 years as a registered official with USA Hockey, serving as officiating supervisor for the Michigan Amateur Hockey Association (MAHA) for 20 years and as Michigan’s referee-in-chief from 2006-15, and he was a member of USA Hockey’s national instructor staff from 1997-2019. An accomplished college official as well, he worked in that capacity for more than 25 seasons, including 15 at the Division I level in the Western Collegiate Hockey Association (WCHA) and Central Collegiate Hockey Association (CCHA).
His time at Calumet has included stepping into many more roles to help provide student-athletes with the fullest possible experience. He served as public address announcer for football for 16 seasons and Calumet hockey for more than a decade. He also lent his voice to radio broadcasts for Calumet volleyball and coached freshman football at the school for two seasons.
Jacques has served on the boards for the Calumet Hockey Association, Calumet All-Sports Booster Club and Calumet High School Band Parents Club, the latter two as treasurer. He remains president of the Hall of Fame board.
“I’m a Calumet grad, and when you’re the athletic director at the school you’re from, I think it’s something a little bit different,” Jacques said. “You bleed the school colors and put that extra effort in because it’s home.”
Jacques played football as a student at Calumet and served as the hockey team’s student equipment manager as a senior. He earned a bachelor’s degree in industrial education in 1989 from Northern Michigan University, and then a master’s in educational administration from NMU in 2000. He received his certified master athletic administrator (CMAA) designation in 2020 from the National Interscholastic Athletic Administrators Association (NIAAA) – becoming the only Upper Peninsula athletic director to achieve that accomplishment.
Jacques also has served his community as a volunteer firefighter since 1991 and as assistant fire chief since 1998.

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.
