Introduction

A routine preseason workout became a life-changing emergency on a sweltering August day in Tempe. A 21-year-old sophomore defenseman stepped into practice with teammates and staff and did not walk away. The collapse of Matthew Mayich during an outdoor training session has halted a team and focused national attention on a margin often overlooked in athletics: the difference between pushing for performance and recognizing when environmental danger overrides the gains sought from hard work.

Arizona State University confirms coaches, athletic trainers and a third party were present when Mayich collapsed. Temperatures in Tempe that day reached 106 degrees. The university now faces the scrutiny common to cases where policy, medical judgment and the practical demands of conditioning collide. For Mayich and his family the stakes are personal and immediate. For athletic departments across hot climates, the event is a prompt to reexamine how training is scheduled, who controls cancellations, how outside vendors are supervised and whether established emergency protocols are being followed as written.

The questions emerging from Tempe are medical, procedural and cultural. They cut across physiology—how quickly body temperature can rise with exertion—to governance—who has the final say on whether outdoor work proceeds when conditions are extreme. This story examines those dimensions, outlines accepted prevention and treatment practices, reviews how institutions can tighten oversight, and considers how climate realities are changing what responsible training looks like.

The timeline and immediate facts: what we know about the workout

On Aug. 20, during a team workout held outdoors in Tempe, Arizona, Matthew Mayich collapsed and was transported to a local hospital. ASU has confirmed the session included coaches, athletic training staff and participation from an outside organization or contractor. Hospital officials and team representatives have not disclosed exhaustive medical details, but Robert Carey has publicly said that Mayich is incapacitated and that the likelihood of recovery is low.

ASU announced a formal internal review to examine the session’s setup and oversight. That review will evaluate the program’s own policies, how staff applied those policies on the day in question, and any relevant guidelines provided by the outside entity that helped run the workout. The review’s scope matters because responsibility for safety does not rest only with a team’s head coach. It extends to athletic trainers, conditioning staff, institutional policy and, increasingly, third-party vendors contracted to run specialized sessions.

Temperatures in Tempe that day reached 106°F. Doctors and heat-safety experts immediately flagged the heat as the principal environmental risk factor. Dr. Frank LoVecchio, a physician quoted by media outlets after the incident, said training under such conditions is “very, very hard” and that it is “very, very unlikely” most people — including many athletes — can endure prolonged exertion without assistance. He emphasized that body temperature can climb rapidly under extreme heat, transforming exertion into an acute medical emergency.

The university’s review will determine whether the session complied with mandated procedures and whether it should have been modified or canceled given temperature and humidity. That review will also likely examine how decisional authority operated that day: which staff member could or did stop the session, how medical escalation was handled, and how quickly emergency cooling and transport were implemented.

Why heat, not intensity, was the defining variable

Conditioning is central to athletic preparation. Coaches push limits because adaptation requires stress. Yet there is a threshold where the environment, not the athlete’s training status, becomes the determinative factor. High ambient temperature, radiant heat from sun exposure, humidity, and the radiant heat reflected from hard surfaces can overwhelm human thermoregulation even in trained athletes.

When core body temperature begins to exceed safe limits, normal physiological processes that support performance turn into liabilities. Sweat production increases, but in high humidity sweat does not evaporate efficiently; heart rate climbs to support both muscular work and cutaneous blood flow; and blood volume prioritizes skin perfusion, often at the expense of muscle and other organs. Heat stress accelerates, and symptoms can progress from cramps and dizziness to altered mental status, collapse and multi-organ dysfunction.

Dr. LoVecchio’s comments capture that progression. His point — that body temperature can rise “very, very quickly” in these circumstances — explains why an otherwise routine team workout can cascade into a medical crisis. That danger is amplified in locations like Tempe, where extreme heat is not an aberration but a seasonal reality. In such environments, weather becomes the primary factor that must shape practice choices.

The governing question is not whether athletes can be pushed, but whether conditions permit pushing safely. That judgment rests on objective measures (temperature, humidity, heat-index or WBGT) and on authority—who assesses that data and who cancels or modifies activity.

The medical picture: exertional heat illness and why rapid cooling matters

Exertional heat illness exists on a spectrum. Early stages include heat cramps and fainting. Left unchecked, the condition progresses to heat exhaustion and, at its most severe, exertional heat stroke (EHS). EHS is characterized by an elevated core body temperature—often above about 40°C (104°F)—accompanied by central nervous system dysfunction, including confusion, collapse or unconsciousness. EHS can cause permanent organ damage and death if not treated immediately.

Clinical understanding of EHS emphasizes two facts that bear directly on the ASU case. First, early recognition is essential. Athletes who feel dizzy, nauseous, unusually fatigued, confused or who vomit during training should be removed from activity and assessed promptly. Second, immediate cooling is the single most important medical intervention. Evidence gathered over decades indicates that rapid whole-body cooling—ideally by immersing the patient up to the neck in cold water—dramatically reduces the risk of death or lasting damage. Delays in cooling, or attempting suboptimal methods like passive cooling without immersion, increase the likelihood of severe outcomes.

Athletic organizations and sports-medicine bodies publish treatment guidance that prioritizes cold-water immersion as the gold-standard field treatment. The principle is simple: reduce core temperature as fast as possible. Practical application requires preparation: immersion tubs or other means of rapid cooling must be available at higher-risk practices, staff must be trained to deploy them without hesitation, and protocols must be in place that give medical personnel the authority to stop a workout and implement emergency measures.

The window for effective intervention is narrow. Several medical studies and consensus statements highlight the “golden half-hour” concept: meaningful reductions in morbidity and mortality are most likely when active cooling begins promptly after collapse. That urgency imposes logistical demands on training sessions—particularly those run outdoors during extreme heat.

Institutional responsibility and the role of third-party providers

When universities contract with outside companies for strength-and-conditioning sessions, small oversights in agreement language can create outsized liability and safety gaps. Contracts that fail to specify who has medical oversight, who has ultimate authority to cancel or modify practices, who provides and maintains emergency equipment, and how emergencies are reported create gray areas that can hinder swift, life-saving action.

ASU’s initial public statement indicates coaches, training staff and a third party were present. That setup raises operational questions: who set the workout’s intensity? Which organization’s protocols governed decisions about weather and heat? Were the athletic trainers empowered to halt activity if conditions were dangerous? Were emergency medical plans rehearsed and documented in advance? The university review will likely analyze contract documents and communications to answer these questions.

Institutions that have encountered similar incidents have learned hard lessons about oversight. Clear chains of command matter. Athletic trainers must have unambiguous authority to stop a workout on medical grounds. Contracts with third-party vendors should include specific clauses about medical responsibility, required presence of certified athletic trainers, adherence to institutional heat policies, and immediate reporting obligations. Without such clarity, decision-making can become fragmented when every second counts.

A related issue is how programs treat expertise and hierarchy. An outside athletic-performance company may bring novel training techniques that appeal to coaches eager to gain an edge. But the presence of such firms does not relieve the athletic department of oversight. Universities must ensure vendors operate within institutional safety frameworks and that university medical staff retain final say on health-related decisions.

Prevention: acclimatization, scheduling, and physiological monitoring

Preventing heat injury requires three converging strategies: reducing environmental exposure, preparing athletes physiologically, and monitoring them during activity.

• Scheduling: Move intense portions of training to cooler hours—early morning or evening—and, when possible, avoid midday heat. Provide shade and cooling stations during outdoor sessions. Rotate indoor and outdoor sessions based on forecasted conditions.
• Acclimatization: Athletes adapt to heat through progressive exposure. Acclimatization protocols typically last one to two weeks and involve gradually increasing duration and intensity of activity in the heat. Properly structured acclimatization reduces risk of exertional heat illness and improves performance.
• Hydration and nutrition: Ensure easy access to fluids and educate athletes about proactive hydration rather than waiting to feel thirsty. Include electrolyte strategies when workouts last many hours or when sweat rates are high.
• Active monitoring: Use objective metrics alongside athlete-reported symptoms. Many programs rely on heat-index measurements, but wet-bulb globe temperature (WBGT) provides a more nuanced assessment by incorporating humidity, wind, radiation and temperature. Staff should track these values and follow predefined thresholds that trigger adjustments or cancellations.
• Individual risk screening: Pre-existing medical conditions, recent illness (particularly fever or viral infections), medications, and body composition can influence susceptibility. Screening athletes before heavy outdoor sessions can identify those who need closer supervision or modified work.
• Progressive intensity: Save the most intense work for later in a practice session or postpone it entirely on high-heat days. Include scheduled rest breaks, cool-down periods and cold fluids.

These strategies require institutional commitment: policies must be written, staff trained, equipment provided and authority centralized to ensure consistent application across teams, coaches and external providers.

Emergency preparedness: what teams must have on-site

Preventive measures reduce risk but cannot eliminate it. Medical teams must be ready to act immediately. Preparedness includes equipment, training and rehearsed procedures.

Equipment and logistics:

• Cold-water immersion options (portable tubs or access to a nearby facility with a large tub) and an actionable plan to use them.
• Thermometers capable of measuring core temperatures; tympanic or oral readings are insufficient for diagnosing EHS.
• Emergency medical supplies and a plan for rapid EMS activation and on-field-to-ambulance transfer.
• Communications protocols that alert coaches, trainers and emergency responders without delay.

Training and authority:

• Staff trained to recognize early signs of heat illness and empowered to stop activity.
• Regular drills that simulate collapse scenarios and rehearse cooling, airway maintenance and transport.
• A clearly documented chain of command that gives medical staff autonomy to prioritize athlete health over training objectives.

Documentation and reporting:

• Incident reporting systems that capture what happened, when, who made decisions and what treatments were rendered.
• Post-incident debriefs that identify breakdowns and required changes to policy or practice.

The absence of any element can be catastrophic. Cold-water immersion is nonnegotiable for suspected EHS. Teams that lack on-site immersion capability must have a predetermined plan that ensures cooling begins immediately—either by transporting the athlete to immersion quickly or by employing alternative rapid cooling methods that still meet clinical effectiveness.

The legal and ethical landscape: accountability and institutional response

When athletes suffer severe harm during institutional activities, two questions follow quickly: was existing guidance followed, and who is accountable? The answers shape remediation, legal exposure and public trust.

Legally, universities face potential negligence claims if they fail to provide a reasonably safe environment or if they breach their own policies. Litigation often focuses on whether staff followed established safety protocols, whether necessary equipment was available, and whether there was a reasonable medical response. Documentation is crucial: clear records of weather monitoring, staff assignments, equipment inventory and decision-making around cancellation or modification strengthen an institution’s defense and provide transparency.

Ethically, universities owe a duty of care to student-athletes. That duty includes preventing foreseeable harm and ensuring that safety considerations take precedence over performance or competitive advantage. When third-party vendors are involved, universities must ensure contractual terms do not shift critical safety responsibilities off their books in practice.

Public inquiries and institutional reviews serve dual purposes: determining accountability and identifying systemic fixes. Independent external reviews are often required to ensure credibility and to recommend changes that internal reviews may miss. Equally important: communicating findings transparently to families, teams and the public. A culture of candor, combined with demonstrable policy changes, helps restore trust.

Past cases and lessons learned: what history shows about heat-related injuries

Heat-related deaths and catastrophic injuries in sport have prompted high-profile reforms. The best-known case is the death of NFL player Korey Stringer in 2001 after a Minnesota Vikings training-camp practice during hot weather. Stringer’s death led to widespread changes in NFL training protocols, including mandatory education on heat illness, improved on-site medical equipment and changes in practice scheduling. The tragedy accelerated adoption of cold-water immersion protocols as a standard of care and pushed athletic organizations to formalize heat-acclimatization policies.

Collegiate and high-school programs have also faced heat-related tragedies and near misses that led to policy revisions. Common patterns emerge from these cases: insufficient attention to environmental measurements, poor communication among coaches and medical staff, lack of immersion capability, and ambiguity in authority to cancel sessions. Where institutions implemented clear, evidence-based policies and practiced emergency drills, outcomes improved.

The ASU case may prompt similar reforms across college athletics, especially in regions with frequent extreme heat. Institutional reviews typically result in recommendations to tighten scheduling rules, require WBGT monitoring, mandate on-site immersion equipment, clarify authority for medical staff to stop practice and create explicit oversight mechanisms governing outside vendors.

Technology and monitoring: tools that can help — and their limitations

Advances in monitoring technology offer tools to reduce risk, though none replace sound policies and trained staff. Wearable sensors can track heart rate, skin temperature and estimated core temperature trends in real time. When integrated into monitoring systems, these devices can alert staff to abnormal physiologic responses before an athlete becomes incapacitated.

Environmental monitoring tools that calculate WBGT in realtime provide actionable data more informative than raw temperature alone. Mobile apps and on-site devices enable staff to make evidence-based decisions about activity adjustments.

Limitations remain. Wearables produce noisy data that require clinical interpretation. False positives can lead to unnecessary interruptions; false negatives can lull staff into complacency. Devices also require calibration, consistent use and institutional protocols that define responses to alerts. Relying solely on technology without the human authority to act is a recipe for failure.

Technology is most effective when it augments human judgment and is embedded in a policy framework that gives medical staff the authority to act on the data without bureaucratic drag.

Practical steps universities should take now

Institutions in hot climates can take immediate, concrete steps to reduce risk.

1. Review and update heat policies: Ensure policies are explicit about who measures conditions, which metrics (WBGT) are used, and at what thresholds practices are modified or canceled.
2. Empower medical staff: Athletic trainers must have clear, documented authority to end or modify workouts. That authority must be recognized by coaches, administrators and outside providers.
3. Formalize vendor oversight: Contracts with third-party vendors should require adherence to university safety policies, presence of certified medical personnel, provision of necessary equipment and immediate reporting of incidents.
4. Equip for rapid cooling: Ensure cold-water immersion capability is available for high-risk sessions. If immersion tubs are not feasible, identify alternative rapid-cooling means and rehearse them.
5. Train and rehearse: Conduct regular emergency drills and incorporate heat-illness simulations into staff training. Rehearsals reduce the time to implement life-saving cooling.
6. Monitor and acclimatize: Implement staged acclimatization for new and returning athletes and use objective environmental monitoring before and during sessions.
7. Communicate with athletes and families: Provide clear pre-season briefings about heat risks, consent for participation, and expectations for hydration and reporting symptoms.
8. Establish transparent incident reporting and external review: When incidents happen, offer an independent review and publish findings and corrective actions.

These steps require administrative commitment and resources, but they are standard practice in many high-performance programs and in professional leagues. For college programs, aligning calendar pressures with safety standards is an ethical necessity.

What athletes and families should know and ask

Student-athletes and their families can play a role in preventing heat-related emergencies by being informed and assertive.

• Ask for the program’s written heat-safety policy. Does it use WBGT or other objective metrics? Who measures conditions and who decides to cancel?
• Confirm that certified athletic trainers are present at every practice and that they have authority to stop activity.
• Ask where rapid cooling equipment is located and whether staff regularly train on its use.
• Report symptoms early. Dizziness, extreme fatigue, nausea, confusion and headache during or after exercise are warning signs.
• If an athlete is ill, recovering from a fever, or newly medicated, they should notify staff before participating. Recent illness increases vulnerability to heat illness.
• Families should expect prompt, clear communication from programs after any serious incident, including a description of immediate response steps and planned review procedures.

Informed athletes and families increase accountability and help create a culture in which safety is prioritized over performance.

How climate trends alter the calculus of athletic training

Long-term climate trends are raising the frequency and intensity of extreme-heat events in many regions. For athletic programs, that means shorter windows for safe outdoor activity during parts of the year, increased reliance on early-morning or late-evening sessions, and growing pressure to adopt more robust heat-mitigation strategies.

Colleges in historically temperate regions are now contending with conditions that previously were rare. As heat becomes a more constant consideration, athletic administrators must build policies that anticipate extreme conditions rather than reacting episodically. That preparation includes investing in indoor training alternatives, upgrading cooling infrastructure, and building long-term acclimatization plans for athletes who will consistently train in rising temperatures.

Climate-driven changes also mean that national governing bodies—conferences, NCAA, and sports medicine associations—will likely need to update guidance and minimum standards. Uniform requirements for monitoring, thresholds for cancellation, and mandatory medical preparedness would reduce variation in practice and improve safety.

The cultural question: when should judgment override tradition?

Athletic culture prizes toughness, resilience and a commitment to pushing through discomfort. Those values serve sports well, but they can also suppress caution when conditions become dangerous. The Mayich case forces a cultural reckoning: which values should govern moments where a single judgment call determines safety?

Athletic programs must cultivate a culture that values prudent medical judgment as an essential component of competitive preparation. That means rewarding staff and coaches who prioritize safety, ensuring that medical professionals’ decisions are respected, and reframing stoppages not as a failure of toughness but as a proper exercise of responsibility.

Shifting culture requires leadership from the top of athletics departments and from university administrations. When decision-making authority and accountability rest clearly with medical staff, and when leaders communicate that safety is nonnegotiable, teams can balance competitiveness with the duty to protect athletes’ health.

Looking ahead for ASU and college athletics

ASU’s formal review of the workout that preceded Mayich’s collapse will be critical. The review must go beyond determining whether checkboxes were ticked; it should analyze decision-making dynamics, communications, equipment availability and how outside vendors were integrated into practice planning. An independent external review could provide further credibility and help identify systemic changes.

More widely, the incident will likely prompt other programs—especially in hot climates—to audit their own practices. Athletic conferences may consider issuing model policies or mandatory minimum standards. Third-party vendors will be scrutinized more closely, and institutions should expect more rigorous contract language and oversight requirements.

For the millions of student-athletes who practice outside each year, the broader lesson is unequivocal: environmental risk deserves as much respect as training philosophy. The right to play and the obligation to protect coexist; institutions must make the balance explicit, enforceable and transparent.

FAQ

Q: What medical condition likely caused Mayich’s collapse? A: Public reports indicate the collapse occurred during an outdoor workout in extreme heat, and medical experts cited heat as the main environmental factor. The clinical conditions typically relevant in such scenarios range from heat syncope and heat exhaustion to exertional heat stroke (EHS). EHS, the most severe form, involves dangerously high core body temperature with central nervous system dysfunction and requires immediate cooling.

Q: How dangerous is exercising in 106°F heat? A: Exercising at such elevated temperatures substantially increases physiological stress. High temperature combined with humidity and exertion can overwhelm the body’s cooling mechanisms, causing rapid increases in core temperature. Even well-conditioned athletes can become vulnerable if exposures are prolonged, intensity is high, and environmental monitoring or cooling measures are absent.

Q: What immediate treatment reduces the risk of death from exertional heat stroke? A: Rapid whole-body cooling—typically via cold-water immersion—is the most effective on-site treatment. The objective is to reduce core temperature quickly. Time to cooling is critical; delays increase the risk of severe organ damage and death.

Q: Who is responsible when a workout involves a third-party provider? A: Responsibility is shared. The university retains ultimate duty of care for its student-athletes and must ensure contractual arrangements with vendors explicitly define medical responsibility, oversight protocols and adherence to institutional policies. Clear lines of authority are essential so that medical staff can act without procedural ambiguity.

Q: What measures should universities adopt immediately to prevent similar incidents? A: Institutions should: adopt objective environmental monitoring (WBGT), require documented acclimatization plans, empower certified athletic trainers with decision-making authority, ensure on-site rapid cooling capability, rehearse emergency procedures, and include explicit safety clauses in vendor contracts. Regular policy audits and independent reviews strengthen accountability.

Q: Can wearable technology prevent heat-related collapses? A: Wearables can provide useful physiologic signals—heart rate, estimated temperature trends—and, when integrated into an alerting system, alert staff to concerning patterns. They are a tool, not a substitute for clear policies, medical authority and immediate access to proven cooling methods.

Q: Will this incident lead to regulatory changes in college athletics? A: High-profile cases often drive policy reviews at institutional and conference levels. Expect heightened scrutiny, model policy recommendations from sports medicine organizations, and possibly more uniform minimum standards for heat monitoring, acclimatization and emergency response across collegiate athletics.

Q: What should athletes do if they feel unwell during hot-weather practices? A: Stop activity immediately, report symptoms to medical staff, seek shade and fluids, and undergo evaluation. Early symptom reporting is crucial; waiting to “tough it out” can lead to rapid deterioration.

Q: How can families support safety for student-athletes? A: Ask programs for written heat policies, confirm the presence and authority of certified trainers at practices, inquire about emergency equipment and plans, and insist on transparent communication after any incident.

Q: What will an effective post-incident review include? A: A thorough review should examine the decision to hold the session, how environmental data were assessed, who made cancellation decisions, equipment availability (especially cooling tubs), timing and quality of medical responses, staff training records, vendor contracts, and recommendations for immediate and systemic changes.

The collapse of a young athlete during a routine workout exposes intersecting failures and opportunities: lapses in environmental assessment, pressure to train through discomfort, gaps in contract language with outside providers, and, most urgently, the need for always-ready medical response. As ASU investigates what happened on that 106°F afternoon, the lessons are already clear for other programs: heat can be the decisive variable in athlete safety, and prudence must govern practice just as much as preparation.
