Winter Preliminary Concussion Data Announced
May 3, 2016

The Michigan High School Athletic Association has found through collection of preliminary data that fewer than two percent of its more than 70,000 winter student-athletes experienced potential concussions during the season that concluded in March.
The MHSAA this school year requested for the first time that member schools report possible concussions by their student-athletes during both practice and competition. A first set of preliminary data announced in December showed only two percent of more than 100,000 high school fall athletes experienced concussions during that first season of the 2015-16 school year.
As it did for the fall, the MHSAA again received data from more than 99 percent of its member high schools at the end of the winter season. The average number of possible winter concussions reported by member high schools through May 2, 2016, was 1.6 concussions per school – half the average per school reported for the fall season. Just more than 39 percent of reporting schools stated they had no concussions by athletes this winter.
Girls and boys basketball, by far the most popular winter sports by participation, also revealed the highest percentage of winter concussions. Girls basketball, with 22 percent of all winter athletes, revealed 38 percent of possible concussions. Boys basketball, with 30 percent of winter athletes, followed with approximately 20 percent of reported possible concussions. Wrestling, with 13 percent of winter athletes, also registered approximately 20 percent of possible concussions.
In addition to breakdowns by sport, the breakdown by gender this winter also was significant. Total, girls make up approximately 38 percent of athletes who compete during the winter season – and girls experienced 48 percent of the possible concussions reported.
“This second set of preliminary data continues to tell a story behind concussions that we anticipated,” MHSAA Executive Director John E. “Jack” Roberts said. “Most importantly, these findings show that concussions are affecting our female athletes just as much as our male athletes. Concussion care is not a football-focused issue, but something we must work to improve for both genders and across all sports. Eventually we will want to encourage and support research that might inform as to why, beyond differences in physiology, more concussions are reported for girls than for boys.”
Data collected by the MHSAA remains preliminary, in part, because results noted include pending reports that have not been verified. After completion of these follow-up reports, the final number of concussions that actually occurred this past season and during the fall may be lower than the preliminary numbers being reported at this time.
The data analyzed to date is for high schools only, although middle schools also have the opportunity to report possible concussions. A full breakdown of the data including concussions by gender, sport, team level (varsity through junior high) and setting (practice or event) will be reported after the conclusion of this spring 2016 season.
The reporting of possible concussions is part of a three-pronged advance by the MHSAA in concussion care during the 2015-16 school year which is producing data related to the frequency and severity of head injuries. The MHSAA this fall launched the largest ever state high school association sideline concussion testing pilot program, with 62 schools taking part by using one of two screening tests designed to detect concussions. One of the objectives of the pilot is to increase awareness of concussions and improve sideline detection; and preliminary results indicate that the average number of possible concussions reported by pilot schools exceeds the average reported by schools outside the pilot group.
Of 30 schools reporting the most possible concussions this winter, seven are part of the MHSAA’s pilot sideline detection programs. Those programs – King-Devick Test and XLNTbrain Sport – utilize technology to provide on-site testing of athletes who have sustained possible concussions, with results of those examinations then compared against baseline tests taken by athletes previously.
The MHSAA also is the first state association to provide all participants at every member high school and junior high/middle school with insurance intended to pay accident medical expense benefits – covering deductibles and co-pays left unpaid by other policies – resulting from head injuries sustained during school practices or competitions and at no cost to either schools or families. The program will produce additional data about the frequency and severity of head injuries. After the fall and winter seasons, only 110 claims have been made on the insurance policy designed to assist in payment for concussion care. Twenty-nine of the claims are for basketball (girls and boys combined), seven are for wrestling and five for injuries experienced during ice hockey activities.
Schools report possible concussions online via the MHSAA Website. Reports are then examined by members of the MHSAA staff, who follow up with school administrators as those student-athletes continue to receive care and eventually return to play. Student privacy is protected.
Previously, the MHSAA also was among the first state associations to adopt a return-to-play protocol that keeps an athlete out of activity until at least the next day after a suspected concussion, and allows that athlete to return to play only after he or she has been cleared for activity by a doctor (M.D. or D.O.), physician’s assistant or nurse practitioner. The follow-up reports schools are providing the MHSAA reveal that the majority of students are being withheld from activity for a week or longer following the reported concussion. This will be discussed in more detail when the MHSAA releases a more comprehensive review that covers the entire school year.
The MHSAA is a private, not-for-profit corporation of voluntary membership by more than 1,400 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.
Survey Shows Small but Steady Rise of Multi-Sport Participation at MHSAA High Schools

The Michigan High School Athletic Association’s seventh Multi-Sport Participation Survey, conducted last spring for the 2024-25 school year, showed small but continuing growth of multi-sport participation among athletes at member high schools.
The annual Multi-Sport Participation Survey was inspired by the MHSAA’s Task Force on Multi-Sport Participation, which was appointed in 2016 to study early and intense sport specialization – a serious issue related to health and safety at all levels of youth sports – and to promote multi-sport participation as a way to help stave off overuse injuries and burnout among athletes that have been tied to chronic injuries and health-related problems later in life.
The 2024-25 Multi-Sport Participation Survey received responses from 82.7 percent of member high schools and showed 45.4 percent of athletes at those MHSAA member high schools participating in two or more sports, an increase of six tenths of a percent from 2023-24. Multi-sport participation has shown increases every year of the study – and a combined increase of 2.6 percent since the first study after the 2017-18 school year.
For 2024-25, 47.8 percent of male athletes and 42.3 percent of female athletes played multiple sports. The percentage of multi-sport athletes remains inversely proportional to schools’ enrollments, as Class D schools again enjoyed the highest percentage of multi-sport athletes at 63.1 percent, followed by Class C schools (59.6), Class B (49.3) and Class A (38.5).
All four enrollment classifications also continued to show increasing multi-sport participation. Class A multi-sport participation increased three tenths of a percent from 2023-24 and is now up 2.6 percent from 2017-18 survey results. Class B increased 1.3 percent from the previous year and is also up 2.6 percent since 2017-18. Class C multi-sport participation grew two tenths of a percent over the previous year and sits 4.4 percent higher than the first study, and Class D multi-sport participation in 2024-25 remained the same as in 2023-24 and has grown five percent over the last seven years.
The MHSAA Task Force also recommended measuring multi-sport participation in MHSAA member schools to recognize “achievers” – that is, schools that surpass the norm.
Battle Creek Harper Creek, Detroit Cody and Grand Rapids Northview have appeared among the top 10 percent of their respective Classes six of the seven years the survey has been conducted. Four more schools have appeared among the top 10 percent of their Classes five of the seven years: Decatur, East Grand Rapids, Manton and Warren Michigan Collegiate. Detroit Douglass, Parma Western and Lake Leelanau St. Mary have appeared among the top 10 percent of their Classes four times apiece.
In Class A, Grand Rapids Northview (79.4 percent) posted the highest percentage of multi-sport athletes for 2024-25, followed by Macomb L’Anse Creuse North (70 percent), Detroit Cass Tech (61.4) and Sterling Heights Stevenson (60.7) also reporting at least 60 percent.
Warren Michigan Collegiate paced Class B schools with 91.3 percent of athletes playing multiple sports, followed by Tecumseh (77.7), Yale (76.6), Detroit Cody (71.4), Battle Creek Harper Creek (71.3) and Manistee (70.1). Class C saw six schools reach 80 percent for the second-straight school year, led by Jackson Lumen Christi (97.6 percent), Martin (89.7), Bad Axe (89.3), Cass City (88.6), Center Line Prep Academy (83.6) and Decatur (82.3).
Watervliet Grace Christian topped the Class D list at 93.8 percent of athletes participating in multiple sports. Next were Watersmeet (89.7), Lake Leelanau St. Mary (88.2), Detroit Douglass (87.8), Vestaburg (87.7) and Portland St. Patrick (87.3).
