• Flow with fluids. Good hydration should begin early in the day before kids even set foot on the playing field. Stay hydrated by drinking plenty of water during the day leading up to a game, especially in the two to three hours before game time. Continue to drink during the game (about 1/2 cup every 15 minutes) and afterward to rehydrate after sweat loss. Water should still be kids’ go-to drink for exercise that’s under 60 minutes. Training sessions over an hour may require a sports drink to replace electrolytes lost through heavy sweating.
