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.

MHSAA member high schools reported a combined participation of 275,684 athletes in MHSAA-sponsored tournament sports during the 2024-25 school year – the highest number of participants in those activities since 2018-19 and despite another decrease in combined enrollment across those 754 schools.
This past year’s participation total was 5,020 students – or 1.9 percent – higher than in 2023-24, while enrollment at member schools fell by 1.3 percent. Boys participation was up 1.9 percent to 161,329 – also its highest since 2018-19 – and girls participation was up 1.8 percent to 114,355, its highest count since 2019-20. MHSAA participation totals count students once for each sport in which they participate, meaning students who are multiple-sport athletes are counted more than once.
Two sports set participation records during 2024-25. Boys track & field counted 24,759 participants – a 3.7 percent increase from a year ago in breaking its previous record from 2005-06. Girls lacrosse participation was up 0.9 percent from last year to 3,970 participants in setting a record for the second-straight season.
Another 15 sports saw participation increases this past school year. Girls tennis saw an increase of 6.4 percent to 9,485 athletes, followed by boys and girls wrestling’s combined increase of 5.2 percent to 12,422 participants – with boys wrestling participation up 3 percent and girls up an incredible 24 percent to 1,505 athletes. Girls track & field (18,108 athletes) and boys cross country (8,209) also saw some of the largest jumps at 4.5 and 4.1 percent, respectively.
Also reporting increased participation during 2024-25 were boys tennis (3.7 percent, 6,163 total athletes), football (3 percent, 36,210), girls volleyball (2.9 percent, 19,679), boys golf (2.7 percent, 7,416), girls competitive cheer (2.4 percent, 6,319), boys basketball (1.7 percent, 20,541), girls cross country (1.4 percent, 6,826), boys soccer (1.1 percent, 14,112), boys bowling (1 percent, 4,333), boys swimming & diving (0.9 percent, 4,073), and girls soccer (0.7 percent, 11,090).
Although 11 sports saw participation decreases during 2024-25 from the previous school year, those for girls basketball (-0.4 percent) and boys ice hockey (-0.7 percent) were lower than the 1.3-percent enrollment decline at MHSAA member schools.
Football remains the most popular sport in terms of participation at MHSAA member high schools, with that total of 36,210 athletes its highest since 2017-18. Girls volleyball remained the most popular girls sport in 2024-25, with its 19,679 athletes the highest total since 2012-13.
The participation figures are gathered annually from MHSAA member schools to submit to the National Federation of State High School Associations (NFHS) for compiling of its national participation survey. Results of Michigan surveys from the 2000-01 school year to present may be viewed the "Sports Participation Listing" page.

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.
