Core Temperature Training
Managing internal heat during exercise through hydration, pacing, clothing, and acclimation so performance holds in warm conditions.
Core temperature training manages internal heat during workouts—hydration, pacing, clothing, and acclimation—so performance does not collapse in warm conditions. Rising core temp elevates heart rate at the same power output; preemptive cooling and electrolytes help long sessions.
Wearables that estimate skin or core temp are trends, not medical devices.
Common questions
-
How do you know core temperature is too high?
Heavy HR drift at easy pace, dizziness, nausea, or confusion are stop signals. Cool, hydrate, and reduce intensity—heat illness is an emergency.
