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.

2023 Bush Award Honorees Groat, Albright, Show Dedication in Multiple Roles

Battle Creek St. Philip’s Vicky Groat and Midland High’s Eric Albright both have devoted themselves to Michigan school sports for multiple decades – and both continue to lead as highly-successful coaches while also serving in multiple administrative roles within their schools and as important voices in statewide leadership as well.

To recognize their dedication and far-reaching contributions to educational athletics, Groat and Albright have been named recipients of the Michigan High School Athletic Association’s Allen W. Bush Award for 2023.

Al Bush served as executive director of the MHSAA for 10 years. The award honors individuals for past and continuing service to school athletics as a coach, administrator, official, trainer, doctor or member of the media. The award was developed to bring recognition to people who are giving and serving without a lot of attention. This is the 32nd year of the award.

Groat will enter this fall’s girls volleyball season with a career coaching record of 1,240-304-95, ranking seventh on the MHSAA coaching wins list for her sport. She took over for her mother, equally-legendary Sheila Guerra, for the 1997-98 winter season, stepped away briefly after her second year, and returned to lead the program again in 2000-01. Groat has guided the Tigers to 14 MHSAA Finals championships, including a record nine straight in Class D from Winter 2006-07 through Fall 2014 (volleyball moved to the fall with the 2007-08 school year), and most recently guided St. Philip to back-to-back Division 4 championships to cap the 2020 and 2021 seasons.

A 1985 graduate of the school, Groat is entering her 17th year as the athletic director and also took over as principal on an interim basis in December 2014 and then permanently to begin the 2016-17 school year. She previously had served as the school’s student services director and as an assistant principal. She also served on the MHSAA Representative Council from 2016-20 and is a longtime leader as part of the Michigan Interscholastic Volleyball Coaches Association (MIVCA).

Groat is a member of the Battle Creek St. Philip Athletic and MIVCA Halls of Fame. She was named Michigan High School Coaches Association volleyball Coach of the Year in 2009, and the national Coach of the Year for her sport by the National High School Athletic Coaches Association in 2021. She earned her bachelor's degree from Central Michigan University in 1989 and master’s from Fort Hays State University (Kan.) in 2019.

“Vicky Groat has established herself as one of the most accomplished volleyball coaches in the state and also wears multiple difficult hats so well as the athletic director and principal,” MHSAA Executive Director Mark Uyl said. “Her passion for St. Philip school and its students is evident at every turn, and her desire to help all students excel has been a great benefit to her school and throughout Michigan.”

Albright came to Michigan from Minnesota, graduating from Royalton High School in 1992 and then Hamline University with his bachelor’s degree in 1996. He began at Midland High as a teacher in 1997 and continued in the classroom through 2013-14, adding the varsity baseball coaching job in 2003 and building a 520-199 record over the last two decades while also leading the Chemics to seven league and four District titles and a Division 1 Semifinals appearance in 2018. He became the school’s athletic director in 2010 and serves as an assistant principal as well.

Midland has hosted various MHSAA postseason events under Albright’s direction, including Finals tennis, Semifinals in soccer and football and Quarterfinals for basketball, softball and volleyball. Albright has served on seven committees or task forces for the Association and as part of the Representative Council since 2019.

Albright also is beginning his tenure as president of the Michigan Interscholastic Athletic Administrators Association (MIAAA) and is a Leadership Training Course instructor for the National Interscholastic Athletic Administrators Association (NIAAA). He received a master’s degree from Central Michigan University in 2000 and earned a certified athletic administrator designation from the NIAAA in 2013. Albright also has been an MHSAA registered official in basketball and baseball over the last two decades, most recently in both sports since 2018-19. He worked as a professional baseball umpire in the Gulf Coast League during the 1997 season before beginning his tenure at Midland.

“Eric Albright is a leader in school-based athletics across Michigan with his work with the MIAAA and MHSAA, and he’s become a go-to person for other athletic directors statewide,” Uyl said. “He has worked tirelessly to provide a wealth of guidance and vision, continuously demonstrating his passion for educational athletics.”
