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.

Retired MHSAA Executive Director Roberts Selected for NFHS Hall of Fame

During an award introduction two years ago, MHSAA associate director Tom Rashid described his longtime close friend Jack Roberts as the leader who “took our darkest hours and problems and turned them into positives.”

The MHSAA has faced its share of challenging times, and those may have been among Roberts’ finest hours over 32 years as MHSAA executive director  and admittedly the times when his adrenaline flowed most. But there were many more good times and memorable advances for Michigan school sports under his leadership, and he will be recognized again this summer both for those and a lifetime of service to school sports in this state and across the nation.

John E. “Jack” Roberts was one of 12 honorees announced Tuesday as this year’s inductees into the National High School Sports Hall of Fame by the National Federation of State High School Associations (NFHS). He will be inducted as one of three former state association administrators selected for the 39th Hall of Fame class at a ceremony during the NFHS summer meeting July 1 in San Antonio, Texas.

He began his tenure as MHSAA executive director in 1986, and at the time of his retirement he was the nation’s longest-serving executive director of a state high school athletic association. He was the fourth person to serve the MHSAA in 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 will become the Hall of Fame’s ninth inductee from Michigan, joining Forsythe (inducted 1983), River Rouge boys basketball coach Lofton Greene (1986), Warren Regina athletic director, softball and basketball coach Diane Laffey (2000), Fennville basketball and baseball standout Richie Jordan (2001), Grosse Pointe Woods University Liggett boys and girls tennis coach Bob Wood (2005), Bloomfield Hills Cranbrook hockey standout Jim Johnson (2007), Owosso football, basketball and baseball all-stater Brad Van Pelt (2011); and Vermontville Maple Valley baseball national record holder Ken Beardslee (2016).

Roberts also follows in the footsteps of his late father, John Roberts, who served as executive director of the Wisconsin Interscholastic Athletic Association from 1957-85 and was inducted into the National High School Hall of Fame in 2000. They will be the first father-son team in the Hall of Fame.

Jack Roberts began his career serving as an assistant director for the National Federation from 1973-80. He was involved with the implementation of Title IX at the local and state levels and made immense contributions as the NFHS representative to the landmark Amateur Sports Act of 1978, and also played a significant role in the NFHS rules-writing process as the organization started writing and publishing rules for a number of new sports during the 1970s.

The MHSAA enjoyed continued growth under Roberts’ guidance, particularly in the number of Michigan students participating in athletics and in the number of MHSAA-sponsored tournament sports available to them. Several key rules changes came under Roberts’ watch and direction, and he made the MHSAA a national leader in health and safety efforts particularly in the areas of head injury care, heart safety initiatives and heat management strategies.

“I had a head start in this work. Growing up in the home of the executive director of the Wisconsin Interscholastic Athletic Association and then spending most of my 20s working for the National Federation office, and much of it with (longtime NFHS executive director) Cliff Fagan, was a jumpstart on this career,” Roberts said. “But I’m also satisfied at this point that, to paraphrase Hamilton in the musical ‘Hamilton,’ I didn’t give up on my shot. I was given a shot, I took it and I didn’t waste the chance.

“The job fit me, and I think I maxed the opportunity I had to serve educational athletics in this job, and that’s satisfying to think about at this time.”

Jack RobertsUnder Roberts’ leadership, overall participation in high school athletics in Michigan increased 10 percent, and the MHSAA 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. His tenure saw the addition of girls competitive cheer (1994), girls & boys bowling (2004) and girls & boys lacrosse (2005) to the MHSAA Tournament sport lineup, the creation of a 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.

Among rules changes put in place during Roberts’ tenure was the addition of opportunities for multiple schools to create cooperative teams in sports where participation is lagging. He also helped Michigan become a national leader in improving sportsmanship; a comprehensive package enacted in 1996 set a statewide tone for appropriate behavior and perspective that continues to make an impact today.

Perhaps the most significant influences by Roberts came on the topics of health and safety. The MHSAA has led nationally in concussion care with its first programming in 2000 and return-to-play protocols enacted in 2010, and with mandated concussion 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.

Also under this leadership, the first program for coaches education was launched in 1987 and evolved into the Coaches Advancement Program, with nearly 34,000 courses administered as part of CAP since 2004-05. 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 Michigan also remains a national leader in student services thanks to a variety of programs that were introduced under Roberts’ leadership.

Internally, he put the MHSAA on the leading edge nationally when it came to use the technology, especially in the realm of communications, where he put special emphasis on telling the story of school sports. “I think I was considered a conservative as to rules for eligibility and competition, and a progressive in how we delivered services to schools and school sports,” Roberts said.

In addition to his work specifically in Michigan, Roberts carried significant influence at the national level. He served as part of the NFHS Board of Directors and led the creation of the NFHS Network for video productions in 2012, serving as that board’s chairperson. He also has served on the board of directors of the National Association of Sports Officials (NASO).

“For 32 years, Jack Roberts was the epitome of what leadership looks like. He was the strongest advocate for high school sports that anyone could ever hope for,” said MHSAA Executive Director Mark Uyl, who succeeded Roberts in 2018. “He is without question one of the preeminent pioneers and difference-makers in the world of high school sports over the past 100 years.

“And other than my father, there has not been a man who has had a bigger impact and positive influence on my life personally than Jack Roberts.”

The National High School Hall of Fame was started in 1982 by the NFHS, and the rest of this year’s class is made up of athletes, coaches, administrators and an official. The 12 individuals were chosen after a two-level selection process involving a screening committee composed of active high school state association administrators, coaches and officials, and a final selection committee composed of coaches, former athletes, state association officials, media representatives and educational leaders. Nominations were made through NFHS member associations. Also chosen for this class were athletes Notah Begay (New Mexico), Walter Payton (Mississippi), Sanya Richards-Ross (Florida) and Thurman Thomas (Texas); sport coaches Ray Crowe (Indiana), Ron Kordes (Kentucky) and Lamar Rogers (Tennessee); administrators E. Wayne Cooley (Iowa) and Becky Oakes (Missouri), official Jeff Risk (North Dakota) and speech/debate coach Susan McLain (Oregon). (Click for more.)

Roberts came to the MHSAA in 1986 from the Fellowship of Christian Athletes, which he served as executive vice president. 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 in retirement they together have increased their contributions to environmental matters and international refugee issues while both serving in leadership roles. Jack Roberts has served as board president for the Refugee Development Center in Lansing for 13 years, and Peggy Roberts served six years as chairperson of the board for Lansing’s Fenner Nature Center.  As part of their environmental work, the Roberts are working within a small group of organizations to help them acquire and preserve land.
