MHSAA Provides Hot Weather Reminders

As summer turns toward the beginning of fall sports practices next week, the MHSAA is providing a familiar but vital reminder that student-athletes need to prepare for activity in the hot weather that traditionally accompanies the beginning of August and the first training sessions of the school year.
Each year, the MHSAA provides information to its member schools to help them prepare for hot weather practice and game conditions during the late summer and early fall. Football practice can begin at MHSAA schools August 7, followed by first practices for all other fall sports August 9.
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.
“We emphasize preparation for hot weather at the start of each fall, but this cannot be repeated enough: If we take precautions and plan as we should, heat illness is almost always preventable,” said John E. “Jack” Roberts, executive director of the MHSAA. “We encourage student-athletes to come to their first practice prepared for hot conditions. But coaches also are trained to assume not all student-athletes will be ready, and to be vigilant in making sure all participants are hydrating properly.”
A number of member schools continue to follow the MHSAA’s Model Policy for Managing Heat & Humidity, which while not mandated for member schools was adopted as a rule for MHSAA postseason competition in 2013. The plan directs schools to begin monitoring the heat index at the activity site once the air temperature reaches 80 degrees and provides recommendations when the heat index reaches certain points, including ceasing activities when it rises above 104 degrees.
The model heat & humidity policy is outlined in a number of places, including the publication Heat Ways, which is available for download from the MHSAA Website on the “Health & Safety” page.
To also assist in acclimatization, football practice rule changes adopted in 2014 allow for only helmets to be worn during the first two days, only shoulder pads to be added on the third and fourth days, and full pads to not be worn until the fifth day of team practice. The policy in detail can be found on the Football page of the MHSAA Website.
Heat, hydration and acclimatization continue to be focuses of the MHSAA’s required preseason rules meetings for coaches and officials. The online presentations discuss the need for good hydration in sports, regardless of the activity or time of year, and informs both how to recognize the early signs of heat illness and the immediate steps to take to respond to those symptoms. The MHSAA requires all head varsity, varsity assistant and subvarsity coaches at the high school level to complete the rules and risk minimization meeting requirement.
The first days of formal practices in hot weather should be more for heat acclimatization than the conditioning of athletes, Roberts reminded, and practices in such conditions need planning to become longer and more strenuous over a gradual progression of time. He noted that schools also must consider moving practices to different locations or different times of day, or change practice plans to include different activities depending on the conditions.
Roberts also noted that student-athletes should make sure to hydrate all day long – beginning before practice, continuing during and also after practice is done. Water and properly-formulated sports drinks are the best choices for hydration, while energy drinks, high-carbohydrate fruit juices (greater than eight percent carb content), carbonated and caffeinated beverages are among those that should be avoided.
The Health & Safety Resources page of the MHSAA Website has a number of links to various publications and information and a free online presentation on preventing heat illness from the National Federation of State High School Associations. Also accessible through the MHSAA Health & Safety page are resources from Sparrow Health System, a member of the Mayo Clinic Care Network, which lends expertise on-site at various MHSAA tournament events and provides an online “Ask the Experts” feature to connect MHSAA.com users with Sparrow sports medicine caregivers.

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).
