Hydration and Performance in Hot Conditions
Discipline 5: Physical Performance — Lesson 8 of 12
Lecturer: Douglas Kerr
You can't catch up on fluid in a couple of hours. This session covers hydrating the day before a hot match, replacing electrolytes rather than just water, and weighing yourself to actually know your sweat rate.
The three rules
1. Start hydrating the day before.
2. Replace electrolytes, not just water.
3. Weigh yourself before and after.
