MHSAA Provides Heat Management Reminders in Advance of Fall Practices

With temperatures in many parts of Michigan expected to push back into the upper 80s next week, this is a pertinent time for annual reminders on training in hot weather that traditionally accompany the beginning of August as Michigan High School Athletic Association member schools prepare to begin fall sports practices.
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 2021 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. 9.
The Health & Safety page of the MHSAA Website has a number of links to various publications and information including guidelines for acclimatization from the National Athletic Trainers’ Association. The preseason publication Heat Ways also 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.
Workout Basics: Warm-Ups & Cool-Downs

You may know a good warm-up — and cool-down — are essential to getting a good workout. You may also know that warming up your muscles and stretching them out after exercise can help prevent injury and keep you at the top of your game.
They’re the two bookends that help maximize a workout. Unfortunately, a lot of exercise enthusiasts don’t know how to warm up and cool down correctly.
Warm-Up Basics
A warm-up is exactly what it sounds like: The goal is to warm up your muscles and prepare your body for whatever you’re asking it to do. Warming up increases your body temperature and helps blood flow to the muscles that you’re using.
So if you’re going to play soccer, your warm-up should touch all of the muscles in your legs and core. Shooting hoops? You’ll need to add shoulders and arms to your routine. Circuit training at the gym? Choose a warm-up that flexes all of the muscles you’re about to use.
The thing that all warm-ups have in common is that they require dynamic (or constantly moving) motion, not static stretching (holding poses for a certain amount of time). In fact, static stretching prior to a workout can inhibit power and strength, especially if you’re doing something like weightlifting.
The anatomy of a solid warm-up:
• Before any activity, do about 10 minutes of light cardiovascular activity, whether walking, biking or jogging.
• Dynamic stretches. After you get your muscles moving, do a series of lunges, jumping jacks or toe touches to stretch a bit.
• Dive in. When you start your workout, begin slowly and gradually increase power and speed.
Cool-Down Basics
After you’ve put your body through a challenge, a good cool-down is essential. It helps slow down your heart rate gradually, relax your muscles and stretch them out.
Cool-down routines should always include some type of motion before you get to static stretching, especially if you’ve just finished a high-intensity workout. Static stretching improves flexibility and performance and it can also help stave off future injury.
As with warm-ups, the right cool-down exercises depend on the activity you engaged in. If you biked for 20 miles, you might coast on your cycle for a while before coming to a stop. If you ran, you might jog or walk before you begin stretching. As with your warm-up, the key is addressing every muscle group you worked during your workout.
The anatomy of a solid cool-down:
• At the end of your workout, slow the pace and intensity of whatever activity you’re doing. So, if you’re running, slow to a jog and then a walk for 5 to 10 minutes before stopping.
• Stretch out the muscles you work, but don’t push past the point where you feel tight. Then, hold the position for at least 30 seconds. That’s how long it takes for the body to overcome its stretch reflex.
• Breathe through your stretches and make sure to finish your cool-down with deep, belly breaths.
Running short on time? Target muscle groups you may have injured in the past or that tend to get sore after activity. Cooling down will preserve your athleticism — and your ability to participate in daily activities — over the long term.
Be Good to Your Body
While there’s some controversy about whether warming up and cooling down can help prevent injury, there’s little dispute that they can help you ease in and out of activity.
The key is to find something that works for you. Your warm-up could be as simple as walking to the gym and doing a set of jumping jacks when you arrive. Your cool-down might just involve ending your workout 10 minutes early so you can slow down.
It doesn’t have to be complicated. It just has to give your heart and blood vessels a chance to breathe before and after activity.
