Drinking enough fluid should be a priority for every player and coach. Water keeps you cool from the inside out, increases blood flow to the muscles and brain, boosts stamina, bolsters focus and gives you the edge others may lack.
Even slight dehydration (-2%) can lead to significantly poor performance. Greater loss causes damage in the form of heat exhaustion
#1 Mental Focus
Adequate water intake thins the blood to keep your brain well supplied with the oxygen it needs to process information quickly. Without it, you will find yourself lacking the ability to think quickly on the field.
Dehydration symptoms: Muddled thinking and slow mental response.
#2 Muscle Strength
Taking in enough fluid allows for quicker muscle reactions and strength. Blood contains the nutrients your muscles crave. Adequate hydration sends blood flow where you need it most – your legs.
Dehydration symptoms: Headache and achy, sore legs that begin to tire easily.
#3 Overall stamina
Keeping a player hydrated before the game begins and especially during halftime can prevent poor performance in the second half of a game when others may be dropping off from exertion and slight dehydration.
Dehydration symptoms: Sudden exhaustion, feeling warmer than normal, dark or cloudy urine, sweating less than normal.
