The Michigan High School Athletic Association (MHSAA) focused some attention in its 2017 fall sports preseason guide on dealing with managing heat and humidity. As athletes prepare for the upcoming season, they need to be wary of the conditions they are working out in and taking precautions.
And it’s more than just drinking water. Here is the report in the fall guide.
According to MHSAA, exertional heatstroke and heat illness is the leading cause of preventable deaths in high school athletics. Students participating in high-intensity, long-duration or repeated same-day sports practices and training activities during the summer months or other hot-weather days are at greatest risk.
The Michigan High School Athletic Association recognizes that there are unique and variable climates in Michigan and that there is no “one-size-fits-all” optimal acclimatization plan. However, we strongly encourage member schools to incorporate all of the fundamentals into any heat acclimatization plan.
Exertional Heatstroke and Heat Exhaustion is Preventable Heat Acclimatization Safety Priorities:
• Recognize that exertional heatstroke is the leading preventable cause of death among high school athletes
• Know the importance of a formal Pre-Season heat acclimatization plan
• Know the importance of having and implementing a specific hydration plan, keeping athletes will hydrated while encouraging and providing ample opportunities for regular fluid replacement Fundamentals of a Heat Acclimatization Program
1. Physical exertion and training activities should begin slowly and continue progressively.
An athlete cannot be “conditioned” in a period of only two to three weeks.
A. Begin with shorter, less intense practices and training activities, with longer recovery intervals between bouts of activity.
B. Minimize protective gear (helmets only, no shoulder pads) during first several practices, and introduce additional uniform and protective gear progressively over successive days.
C. Emphasize instruction over conditioning during the first several practices.
Rationale: The majority of heat-related deaths happen during the first few days of practice, usually prompted by doing too much, too soon, and in some cases with too much protective gear on too early in the season (wearing helmet, shoulder pads, pants and other protective gear). Players must be allowed the time to adapt safely to the environment, intensity, duration, and uniform/equipment.
2. Keep each athlete’s individual level of conditioning and medical status in mind and adjust activity accordingly. These factors directly affect exertional heat illness risk. Rationale: Athletes begin each season’s practices and training activities at varying levels of physical fitness and varying levels of risk for exertional heat illness. For example, there is an increased risk if the athlete is obese, unfit, has been recently ill, has a previous history of exertional heat illness, or has Sickle Cell Trait.
3. Adjust intensity (lower) and rest breaks (increase frequency/duration), and consider reducing uniform and protective equipment, while being sure to monitor all players more closely as conditions are increasingly warm/humid, especially if there is a change in weather from the previous few days. Rationale: Coaches must be prepared to immediately adjust for changing weather conditions, while recognizing that tolerance to physical activity decreases and exertional heat illness risk increases, as the heat and/or humidity rise. Accordingly, it is imperative to adjust practices to maintain safety and performance.
4. Athletes must begin practices and training activities adequately hydrated. Rationale: While proper hydration alone will not necessarily prevent exertional heat illness, it will decrease risk.
5. Recognize early signs of distress and developing exertional heat illness, and promptly adjust activity and treat appropriately. First aid should not be delayed! Rationale: An athlete will often show early signs and/or symptoms of developing exertional heat illness. If these signs and symptoms are promptly recognized and the athlete is appropriately treated, serious injury can be averted and the athlete can often be treated, rested and returned to activity when the signs and symptoms have resolved.
6. Recognize more serious signs of exertional heat illness (clumsiness, stumbling, collapse, obvious behavioral changes and/or other central nervous system problems), immediately stop activity and promptly seek medical attention by activating the Emergency Medical System. On-site rapid cooling should begin immediately. Rationale: Immediate medical treatment and prompt rapid cooling can prevent death or minimize further injury in the athlete with EHS. Ideally, pools or tubs of ice water to be used for rapid cooling of athletes should be available on-site and personnel should be trained and practiced in using these facilities for rapid cooling. Ice water baths are the preferred method for rapid cooling, however, if ice water pools or tubs are not available, then applying ice packs to the neck, axillae, and groin and rotating ice water-soaked towels to all other areas of the body can be effective in cooling an affected athlete.
7. An Emergency Action Plan with clearly defined written and practiced protocols should be developed and in place ahead of time. Rationale: An effective emergency action plan (EAP) should be in place in case of any emergency, as a prompt and appropriate response in any emergency situation can save a life. The EAP should be designed and practiced to address all teams (freshman, junior varsity, varsity) and all practice and game sites.
