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.
How To Warm Up Correctly Before Playing Different Sports
July 10, 2024
When you see professional athletes gearing up to race or getting ready to take the field, you’ll notice that they’re always in motion. That’s because they are warming up in preparation for going all out.
And there’s a good reason why you’ll never see a pro go straight from the bench into a full sprint. “You need to allow your muscles to gradually accept the demands of your activity,” says Jennifer Burnham, a certified athletic trainer at Henry Ford Health. “Otherwise you risk causing an injury.”
Why You Should Warm Up
As the name implies, a warmup is a series of movements designed to warm up your muscles. “You want to increase blood flow to your muscles and loosen up and lubricate your joints,” says Burnham. “And you need to do it gradually, so that your body has time to adapt to the increasing intensity.”
Warming up involves more than just stretching. According to Burnham, studies have actually shown that holding a static stretch when muscles are cold can decrease performance. “Instead, before activity you want to do a dynamic warmup that incorporates movement as well as some gentle stretching."
Your warmup only needs to take 5 to 10 minutes. When deciding what to do, think about the movements you’ll be doing in your activity and which muscles and joints are most involved. Then choose movements that slowly get them warmed up and primed for more intense action.
How To Warm Up For Different Activities
No matter your sport, the warmup before your workout should include some exercises to activate and engage your core (the abdominal and back muscles). “Waking up those muscles helps decrease injury potential,” says Burnham. She suggests incorporating bridges and mini squats (no deeper than 45 degrees) into your warmup routine. To do a bridge, lie on your back, knees bent, feet flat on the floor. Tighten your stomach muscles and squeeze your butt as you lift your hips up to form a straight line from knees to shoulders.
The rest of your warmup can be more specific to muscles and movements of your planned activity.
Running
Before a run, or even a jog, you want to warm up all the muscles and joints from the waist down.
- Rotate your hips (lift your knee up and do some circles in both directions to move the joint) and ankles (circle one foot at a time both clockwise and counter-clockwise).
- Get powerful muscles like your glutes and quads ready with high knees and butt kicks.
- Walk on your toes and then on your heels to warm up shin and calf muscles.
- When you’re ready to run, start off slowly and gradually increase your speed.
Racquet sports
You still need to warm up your lower body using the same moves as the running warmup. But you’ll want to add in others specific to the upper body movements of tennis, pickleball or other racket sports.
- Warm up shoulders with big arm circles both forwards and backwards
- Circle your hands in both directions to get wrists ready for action
- Lunge forward and rotate your upper torso to increase your spine mobility
Basketball, soccer and football
You want to make sure your lower body has time to adapt to the demands of sports that require bursts of sprinting and quick shifts of direction. Your warmup should gradually increase in speed and intensity as you move your body in all directions:
- Side shuffles while swinging your arms (shuffle in both directions)
- Grapevines in both directions
- Skip forward, lifting knees high, then skip backward
Swimming
Prepping your body for a swimming workout means warming up your arms, shoulders and upper back.
- Circle arms backwards and forwards
- Use a light resistance band to do shoulder rows
- Use a light resistance band or light dumbbell and lift straight arms up to shoulder height in front and to your sides
- Start with an easy tempo freestyle swim before going into more dynamic strokes like butterfly
