MHSAA Provides Heat Management Reminders in Advance of 2023 Fall Practices

Temperatures reached record highs in some parts of Michigan at the start of this summer, and heat waves have made headlines nationally over the last month. Although the state didn’t experience similar extremes during July, the beginning of August always is a pertinent time for reminders that more hot weather is likely in many areas and should be prepared for as Michigan High School Athletic Association practices are set to begin Monday, Aug. 7.

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. Practices for all Fall 2023 sports – cross country, football, Lower Peninsula girls golf, boys soccer, Lower Peninsula girls swimming & diving, Lower Peninsula boys and Upper Peninsula girls tennis, and volleyball – may begin Monday, Aug. 7.

The “Health & Safety” page of the MHSAA Website has links to several information sources, including the MHSAA preseason publication Heat Ways, which is available for download and includes valuable information on heat management in addition to requirements and resources regarding head injuries and sudden cardiac arrest.

The first days of formal practices in hot weather should be more for heat acclimatization than the conditioning of athletes, and practices in such conditions need planning to become longer and more strenuous over a gradual progression of time. 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. Furthermore, football practice rules 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 MHSAA advises student-athletes to 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.

A number of member schools 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. (When the temperature is below 80 degrees, there is no combination of heat and humidity that will result in a need to curtail activity.) The model heat & humidity policy is outlined in a number of places on the MHSAA Website, including as part of Heat Ways.

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).
