Professor Yuri Hosokawa's research lab specializes in environmental and emergency medicine, with a primary focus on preventing and managing exertional heat illness (EHI) in athletes. The lab investigates the integration of climatological data into event planning, the efficacy of non-invasive core temperature monitoring (e.g., ingestible sensors), and the development of evidence-based protocols for prehospital care in mass sporting events. Research also emphasizes risk stratification, particularly among high-risk populations such as student-athletes in contact sports, and the adaptation of emergency care strategies for athletes with disabilities, including in Paralympic settings.
Figures are computed from collected data and may differ slightly.
A coordination of care among all medical stakeholders at the sports venue, during transport, and at the hospital is warranted to ensure effective management is provided to the EHS athlete.
Directors of mass sporting events should consider using climatologic data in their organizational decision making to assess the potential heat illness risk and to implement risk-mitigation plans.
After participants completed a warm-weather road race, TGI provided a valid measure of body temperature compared with the criterion measure of TREC. Therefore, TGI may be a viable option for monitoring postexercise-induced hyperthermia, if the pill is administered prophylactically.
Prehospital management of EHS in the Paralympic setting employs the same procedures as for Olympic athletes with some important alterations.
In conclusion, the highest rates of sports-related death among Japanese student athletes were observed in the following: rugby, male athletes, and during practices. The leading cause of death was sudden cardiac arrest.
Assessment of wet bulb globe temperature at the site of activity and throughout the duration of the event is recommended to assist clinicians and administrators in making appropriate decisions regarding the duration and frequency of activity and rest periods. Activity-modification guidelines should be predetermined and approved by stakeholders and should outline specific actions to be followed, such as the work-to-rest ratio, frequency and timing of hydration breaks, and adjustment of total exer
Clinicians should consider an MH-like syndrome when a diagnosis of EHS or ER cannot be fully explained by clinical signs and symptoms presented by a patient or when recurrent episodes of EHS or ER (or both) are unexplained. Further research is required to elucidate the genetic and pathophysiological links among MH, EHS, and ER.
Tokyo 2020 Summer Olympics are projected to experience environmental heat stress that surpasses the environmental conditions observed in the Atlanta (1996), Athens (2004), Beijing (2008), and Rio (2016) Summer Olympics. This raises particular concerns for athletes who will likely to be exposed to extreme heat during the competitions. Therefore, in mass-participation event during warm season, it is vital for the hosting organization to build preparedness and resilience against heat, including app
Elite athletes competing at high-intensity in the hot and humid ambient conditions of the upcoming Games of the XXXII Olympiad (Tokyo 2020) are likely to reach elevated core temperature (≈41.5°C) as previously reported in elite competitions in the heat and the risk of exertional heat stroke (EHS) is heightened.1 EHS is a medical condition defined as an internal body temperature exceeding 40.5°C with central nervous system dysfunction (eg, disorientation, aggressiveness, hysteria, delirium, alter
