Traditionally, endurance sports had been encouraged to drink drink moderately high amounts in order to prevent loss of fluid. However, there is no clear consensus on the real need for these recommendations. In addition, the replacement of sodium through commercial beverages industry has popularized the commercial sports drinks with the idea of preventing hyponatremia.
To this question several questions arise:
1) What is optimum amount of liquid in each person and in different environmental conditions?
2) replacement of minerals is required to prevent hyponatremia?
3) What grade affects athletic performance dehydration?
Based on these general questions, descriptive way you can target:
1) As the temperature and the humidity is higher increases fluid loss of body weight loss increased. General recommendations suggest intake of 150-250 ml every 15 minutes of exercise (between 800-1200 ml per hour) to avoid exceeding 2% dehydration is related to the decrease in athletic performance (SJ Montain, 2008) . However, other studies point in the opposite direction showing that further dehydration to 2% does not reduce athletic performance (Maciejczyk M., 2014). A prominent scientist Tim Noakes in their, widely defends the intake of fluids and salts excessively is not necessary and that athletic performance and health is most at risk with increased intake of fluids and salts (T Noakes , 2011).
2) In a recent scientific review suggests that replenishment of fluid and minerals should be done according to individual responses and environmental conditions (Baker L, 2014). Importantly, increasingly, both athletic training and nutritional recommendations for individual response monitoring of physiological responses and improved athletic performance is employed.
3) Parace important to highlight the importance of the duration of the sporting event to draw important conclusions on the subject. For example, it seems obvious to think that evidence of close to 1 or 2 hours duration, the replacement of fluids and salts is not as important as in testing more than 3 hours (T Noakes, 2011). The physiological explanation for this point is that despite the sodium lost through sweat, if we increase fluid intake rapidly increases the chance of developing hyponatremia.
In conclusion, each athlete should estimate its perceptual and objective response of athletic performance test based on their own individual response with a higher intake of fluid and salt or less.
Note that in the high-performance sports when exercise intensity is high there is an excessive attachment to the following popular beverage intake recommendations every 15 minutes or 1200ml per per hour. Therefore, it is probable risk in athletes ingesting high amount of fluid and salts.
