From the physiological standpoint, it is estimated that approximately 60% of our body weight is water. It is also a well-known fact that our body needs liquids more often than it does food. In addition, we know that our cells are formed by an aqueous medium, that blood contains approximately 80% of water, that the chemical reactions that take place in our metabolism are performed in an aqueous medium …
But, how much water do we need to drink? We usually speak of around 2 litres of water a day as being sufficient for our body to fulfill all its necessary functions. However, certain vital situations exist where these recommendations may vary both in quantity and with regard to the particular characteristics of water.
Physical exercise produces an excessive loss of fluids through sweating, and this means that the body's water needs are increased. Generally speaking, when practising sports, we do not place sufficient importance on consuming liquids. This may cause serious physiological problems, such as the blood volume being inadequate and heat not being able to dissipate properly through the dilatation of the blood vessels in the skin and sweating when performing physical exercise.
Another problem that we may face is a poor physical performance. One of the most
important causes of this is that most of the water lost in sweating comes from water
forming part of blood, and this leads to a blood volume reduction. Without adequate
hydration before, during and after practising sports, this blood volume reduction may
cause cardiovascular problems, and consequently reduce physical effectiveness.
Another cause for the low physical performance is fatigue. Muscular fatigue is the
impossibility to generate the required or expected force, whether or not this is produced
by previous exercise. Fatigue intends to prevent the appearance of major cellular lesions. This fatigue can be caused by different factors
(lack of proper training, metabolic changes, water-electrolyte disturbances…)
When practising physical exercise the most important muscular energy intake takes place through an aerobic system that is able to transform glucose into energy. However, this system has a limited capacity, and once this capacity has been exhausted, anaerobic glucolysis occurs, which renders less energy and generates lactic acid. A high production of lactic acid leads to a fall in blood pH. A method is required to prevent this fall in the pH, thereby delaying the development of fatigue.
Some authors report that the intake of alkalising drinks with a high content in sodium bicarbonate, such as Vichy Catalán, may have an effect on the performance of people who practise sports. Vichy Barcelonamay increase the concentration of bicarbonates in plasma and in the interstitial space, and facilitate the discharge of protons and lactate from the muscle fibre, limiting the acidification of the intracellular medium.
The regular consumption of liquids containing sodium bicarbonate is highly
recommended, to increase resistance to fatigue. Due to its high content in sodium
bicarbonate, potassium, magnesium and other minerals, Vichy Barcelona has a
favourable effect on the resistance in both competitive and amateur sportsmen.
For this reason, we can assure that Vichy Catalán is a natural isotonic drink, with equal
osmolality to that of plasma and intracellular liquids, which promotes the absorption of
all its components much more effectively than a non-isotonic drink. Consequently, the
consumption of this product after exercise prevents dehydration, promotes a rapid
recovery of the fluids lost through sweating and helps to obtain an improved muscular
