A person can survive a long time without food, but not without water. Water participates in almost all metabolic reactions; it helps to lubricate joints, acts as a shock absorber for the nervous system and suppresses the appetite to help the body metabolize fat. Hydration is probably the most overlooked element in sports performance. Thirst acts as to provide needed water, but it lags behind the body’s need. It is important to drink large quantities of water daily, because dehydration can have significant impacts on performance. These impacts include overheating, disruption of chemical balance, fatigue, cramping, decreased speed and quickness, headaches, and dizziness.
-Dehydration causes your body to burn more of its muscular energy stores.
-Thirst sensors are inhibited during strenuous exercise.
-The thirst mechanism generally doesn’t work well enough to prevent dehydration.
-During performance a 2% or greater loss in body weight from dehydration can seriously impair performance.
