Raising Expectations for Managing Heat and Humidity

February 19, 2013

The MHSAA Representative Council is scheduled to vote on March 22, 2013, to approve a “Model Policy for Managing Heat and Humidity” that would appear in the 2013-14 MHSAA Handbook.

The policy, patterned after a mandatory policy of the Kentucky High School Athletic Association, requires that temperature and humidity readings be taken at the site of activities 30 minutes before the start of the practice or competition and again 60 minutes after the start of that activity.  The readings must be recorded in writing and kept in the files of school administration.  Inexpensive devices may be used that automatically calculate the “heat index.”

If the heat index is below 95 degrees, only normal precautions are required.  However, readings of 95 to 99 degrees and then 100 to 104 degrees require additional precautions; and all activity must be postponed or suspended if the heat index climbs above 104 degrees.

When the air temperature is below 80 degrees, there is no combination of heat and humidity that will result in need to curtail activity.

This is being proposed as a model policy for 2013-14.  The MHSAA will monitor school districts’ acceptance of this policy or adoption of similar policies before considering a mandate of this or similar policies.

The model policy will be mandatory for MHSAA tournaments. 

One Concussion Conclusion

August 25, 2017

After both the first and second years of collecting head injury reports from all Michigan High School Athletic Association member high schools for all practices and events in MHSAA sports, we cautioned people to refrain from making too many conclusions.

It’s too soon. We now have a baseline, but we will need several years before we can be certain that we’ve spotted trends or trouble spots.

Nevertheless, one observation screams out. Girls report two to three times the number of concussions that boys do. In basketball, soccer, and in softball compared to baseball, girls report two to three times as many concussions. That was true in year one; it remained true in year two.

It may be that girls sustain more concussions than boys, or that girls are more forthcoming in reporting than boys are, or both. In the past, researchers have published both conclusions.

In either case, it means we need to coach boys and girls differently, and we need to prepare coaches differently for boys and girls teams, as we are doing in the MHSAA Coaches Advancement Program.
