Proper hydration is essential for anyone who exercises, but especially for athletes and fitness enthusiasts.
Since water is one of the most critical components of the body, even minimal dehydration can hinder your sports performance and ability to recover from any type of exercise.
The reason for this is simple: water composes about 75 percent of muscle tissue and about 10 percent of fatty tissue.
But more importantly, water regulates body temperature, aids digestion, protects vital organs, cushions joints, facilitates cellular communication, transports nutrients to the cells, and removes waste, including lactic acid (the primary cause of exercise-related muscle soreness).
In one hour of exercise, the body can lose a quart or more of water, depending on the air temperature and exercise intensity. Thus, proper hydration before, during, and after exercise is critical for performance as well as health safety.
In addition to water loss, important electrolytes, electrically charged minerals in the body such as sodium, potassium and chloride, can be flushed out of the body through sweating during exercise.
Sports drinks are designed to replace electrolytes in the body and they do have their place in high-intensity or endurance exercise lasting longer than 60 minutes.
In addition, people who sweat profusely or who exercise in hot weather should consider some type of re-hydration drink that will replenish electrolytes.
However, commercial sports drinks do NOT replace the body’s essential need for water. In addition, I do not recommend sports drinks since they are highly acidic and full of sugar.
A healthier way to replace electrolytes in the body is to simply drink fruit juice (no sugar added) diluted 50/50 with water and add with one-half teaspoon of natural, unrefined sea salt per quart of juice.
For optimal results, the quality of fruit juice and salt you use is important. Thus, I recommend organic fruit juice and Celtic sea salt, Himalayan crystal salt, or Utah sea salt, since these salts not only contain sodium, but as many as 80 trace minerals.
This simple re-hydration drink can easily be prepared at home in minutes. I encourage parents to make it ahead of time and put it in an empty sports drink bottle (such as Gatorade or Powerade). Most children will never know the difference! See Water vs Sports Drinks for more on this topic.
During exercise, if the body does not have enough water to cool itself, it will become dehydrated. In extreme situations, this can lead to heat exhaustion or even a heat stroke.
When even slightly dehydrated, the body will lack energy and muscles may also cramp during or after exercise. Recovery time will also be slower.
According to the American Council on Exercise, dehydration during exercise leads to muscle fatigue and loss of coordination. In fact, even a small amount of water loss may hinder performance.
Exercise physiologists and scientists have proven that just 2 to 3 percent hydration loss equates to about 10 to 15 percent decrease in endurance and muscle strength.
For example, at this level of dehydration for someone who normally runs the marathon in about 2 hours and 30 minutes, a 3 percent hydration loss could mean running 15 minutes slower!!
A 4 to 5 percent hydration loss equates to about 30 percent decrease in one’s capacity for physical exertion. For serious athletes, this is highly significant!!
In order to prevent dehydration, anyone who exercises (especially athletes) should drink water before, during, and after the workout.
The following tips can help ensure your body has the hydration it requires for optimum exercise performance and recovery. These are general guidelines and may need to be increased for high-intensity or endurance activities or races.
If you are a serious athlete, you may want to weigh yourself before and after workouts to keep track of your fluid losses. Doing so will help you develop an individual hydration schedule.
