Click for Hot Weather and Hydration Resources
July 24, 2012
The extreme temperatures this Summer in advance of the start of another season of high school sports give cause for concern about physical activity in such conditions, and the Michigan High School Athletic Association continues its role in providing its member schools educational information to assist them in minimizing the possibility of heat-related catastrophic injuries to student-athletes.
The topic of heat-related injuries receives a lot of attention at this time of year, especially when deaths at the professional, collegiate and interscholastic levels of sport occur, and especially since they are preventable in most cases with the proper precautions. In football, data from the National Federation of State High School Associations shows that 35 high school players have died from heat stroke between 1995 and 2010.
Each year, the MHSAA provides information to its member schools to help them prepare for hot weather practice and game conditions in the late Summer and early Fall. Football practice can begin at MHSAA member schools on August 6, followed by all other Fall sports on August 8.
Even before the days of the Internet, the MHSAA was providing resources each Spring to assist schools in their preparation for hot preseason practices. That same information is now available online for all interested parties to utilize, including a link to a free online course, A Guide to Heat Acclimatization and Heat Illness Prevention, produced by the National Federation of State High School Associations. The Health & Safety Resources page of the MHSAA Website has a set of Frequently Asked Questions about dehydration and a page dedicated to hydration and heat illness where preventative steps are outlined, as well as the signs and symptoms of heat illness and action steps to take when it is observed.
Visit MHSAA.com, click on Schools, and then on Health & Safety Resources to find the information.
“Heat stroke is almost always preventable,” said John E. “Jack” Roberts, executive director of the MHSAA. “We know now more than we ever have about when the risk is high and who is most at risk, and we’re fortunate to be able to communicate that information better than ever before to administrators, coaches, athletes and parents. We encourage everyone to avail themselves of the information on our website and through other sources, and to take the online course through the National Federation.”
Roberts added that the first days of formal practices in hot weather should be more for heat acclimatization than the conditioning of athletes, and that practices in such conditions need planning to become longer and more strenuous over a gradual progression of time.
“Then, schools need to be vigilant about providing water during practices, making sure that youngsters are partaking of water and educating their teams about the need for good hydration practices away from the practice and competition fields,” Roberts said.
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).
