In the professional academies at clubs like Chelsea or Man City, players have their hydration levels tested with scientific equipment every morning. At the grassroots level, we don’t have that luxury. However, there is a “low-tech” way to know if you’re match-ready that every young player should know: the hydration colour chart.
The “Traffic Light” System
It might sound a bit “gross” in the changing room, but your urine colour is the most honest coach you’ll ever have.
- Pale Straw/Clear: You’re in the “Green Zone.” Your body is fully hydrated, your reaction times will be peak, and your muscles are elastic.
- Apple Juice/Yellow: You’re in the “Amber Zone.” You’re already dehydrated. Your heart is working harder than it needs to, and you’re likely to tire before the 70th minute.
- Irn-Bru/Dark Orange: You’re in the “Red Zone.” You are at high risk of injury. Your coordination will be off, and you shouldn’t even step onto the pitch until you’ve downed at least 500ml of water.
Building the Habit
Teaching young players to check their hydration isn’t just about the next match—it’s about professional discipline. If you want to play at a higher level, you have to treat your body like a machine. The Tip: Hydration starts the day before the game. If you’re trying to fix a “Red Zone” status ten minutes before kick-off, you’ve already lost. Drink consistently on Friday to ensure you’re “Clear” by Saturday morning. It’s the easiest way to improve your game without even touching a ball.
