From dehydration to hyperhidration isotonic and diuretic drinks and hyperhydratant aids in sport. Public Center for Teaching Sports. Basque Government 2 Department of Physiology. The needs of water and electrolytes are quite variants, depending on age, hlpertonicas or environmental conditions. On the contrary, hyperhydration can be dangerous and is associated with hyponatremia that can cause cerebral edema or respiratory failure.

Sports drinks should moisturize, providing minerals and carbohydrates and increase the absorption of water by an ideal combination of salts and sugars. Therefore, it is important to provide correct hydration-protocols before, during and after physical activity, as well as know possible limitations of the sport.

The need of water and electrolytes vary according to age, physiological or environmental conditions. Water is an essential part of the body fluids and the means of transport of substances, is part of various bodily secretions and is the medium where biochemical reactions occur. From the standpoint of digestive physiology it attends multiple processes and regulates body temperature. The main functions of water in relation to physical activity are: Individuals with less body water women, obese, elderly have increased risk of dehydration and should control more their hydration.

Thus, subjects with more fat, less water will. However, long-term sports marathon, triathlon We have also obtained documents with the search engine “Google Scholar” and a snowball strategy, in order to get more items. Search was done between the yearsintegrating other relevant articles through the snowball search strategy. It reduces plasma volume, increases heart rate HR decreases blood flow to the skin, sweating and heat dissipation is reduced and body temperature increases by 1 o C, and when it reaches 39 o C, performance fell drastically by a malfunction of energy production and neuropsychological impairment.

Thus we can classify the effects of dehydration levels table I. It increases cortisol and consequently the same load of exercise may prove more fatiguing. On the other hand, hyperhydration common in endurance races can also be hazardous, 10 being associated with hyponatremia. It can cause cerebral edema or respiratory failure. It is treated with hypertonic beverages, as those used after sporting events 12 and with proper heat acclimatization for days training in hot and high humidity environments.

Knechtle B et al. In sports of short duration, such as those of high intensity force, dehydration reduces the ability of the central nervous system to stimulate muscle contraction. In turn, in swimmers, we observe differences in respect to other water sports. If the water temperature is below that of the body, sweat loss is smaller.

Water and electrolyte needs in sport It is important to know where the hydric losses and intakes come from. Among the daily losses we have urine Lsweat 0,1 Ltranspiration 0,3 L and faeces 0,1 L. Water taken Lcomes from drinks Lfood 1,6 L and metabolic water 0,4 L. The water needs depend on the intensity of the activity and thermal stress, 0. It is difficult to assess the needs of each group or individual, as they vary a lot even in the same individual depending on several factors such as environmental conditions and physical activity.

In sports, to dissipate heat it occurs mainly through sweating, not to mention losses due to hyperventilation.

In the sporting context electrolytes are critical table II. Lower temperatures 10 o C slow the absorption of the beverage and above 20 o C are not desirable.

Bebicas is important to maintain proper temperature of the drink, especially in hot environments being able to use ice cubes and keep it cool and appetizing as well. There are diuretic beverages, such as alcohol.

As beer has a high glycemic index, it could help the recovery of muscle glycogen postexercise, but sports drinks are more appropriate to have a correct osmolarity, salt concentration and optimal HC. However, according to Maughan et al. According to Del Coso et al.

But these effects diminished if taken with isotonic drink, not affecting an exercise of 2 h at 36 o C, thus its effects could only be observed in very long distance races and not exposed to heat. Nor has the diuretic effect of tea on regular users been found, and yet it seems to improve mood.

The hydration protocol table III must be individualized to each sport, environmental conditions and needs. This should be investigated in each team-athlete the loss of water and Na, under given conditions.
