Thermoregulatory study of 200 marathoners in various environmental conditions using ingestible temperature sensors. Critical core temperature thresholds identified for heat-related performance decline and medical intervention. Pre-cooling strategies, including cold water immersion 30 minutes pre-race, lowered starting core temperature by 0.8°C and improved performance in warm conditions. Hydration protocols emphasizing sodium replacement proved crucial for thermoregulation.
