and athletic performance are inseparable and critical to maintaining mental,
cardiovascular, and muscular function during demanding physical activity. This is particularly true for endurance
activities lasting over one hour.
When we consider the fact that our muscles are 70% water, it's easy to understand how important hydration is to muscle function and recovery. Every biochemical reaction that occurs in the body occurs in water.
Water is essential to:
A water deficiency can produce dysfunctions such as: reduced brain function and loss of the mental edge necessary in athletic performance; and decreased blood volume that causes fatigue and forces the heart to work harder to deliver oxygen to the muscles. Severe dehydration can result in serious, and possibly life-threatening, conditions.
Water loss from sweating reduces sodium – the most important electrolyte during athletic performance.
Signs of dehydration include: decreased urination, fatigue, feeling lightheaded, weakness, and thirst. When you begin the feel thirst, you have most likely lost about 2% of your body weight in water and are under-hydrated. Thirst is an alert mechanism that indicates your body is approaching a dehydrated state, which is about a 5% depletion.
Hydration and athletic performance are inseparable to ensure zero impairment for the optimum physical and mental states during these demands.
Water loss through sweat and breathing depends on the intensity, duration, and weather. Because you can’t actually store water in your body, it is necessary to periodically ingest sufficient water to replace the loss.
The American College of Sports Medicine suggest drinking 17-20 ounces of water or sports drink 2-3 hours prior to running, 10-12 ounces 15 minutes before, and then 3-6 ounces every 20 minutes. Much of this depends a lot on personal trial and error because these recommendations are not exacting for every individual need.
Many athletes tend to hydrate instinctively; however, this may require paying attention to thirst. If you are one of the many athletes who tends to ignore that trigger you may become increasingly dehydrated as a result.
Most of us realize that we sweat more when it is hot or humid; but, dehydration can occur during cold-weather exertion.
High-altitude activity may cause heavier breathing because the air is thinner, so it is important to remember that water is lost during those exhales.
In his book, Waterlogged: The Serious Problem of Overhydration in Endurance Sports, Noakes advises endurance athletes to trust their thirst to avoid over-hydration.
I encourage you to check out sports nutrition expert Robert Portman’s book, Nutrient Timing, in which he presents cutting-edge research for athletes to create workout and competition plans that enable optimum nutrition to working muscles.
Waterdrop specializes in providing a variety of water purification solutions such as: water filter pitchers, refrigerator replacement filters, water filter straws, and an under-sink water reverse osmosis system.
Sports hydration drinks are better than plain water because they provide certain nutrients that are lost during exercise.
It isn’t necessary to consider sport drinks if you are exercising less than one hour – unless the activity is very intense.
Sports drinks provide the following hydration for athletic performance.
Sports drinks are not the same as designer waters with added vitamins and minerals. Those drinks are meant to supplement your diet, not replace water and nutrient loss during exercise.
It will always serve you well to remember the important connection between hydration and athletic performance before, during, and after any rigorous or endurance exercise.
