Following the rules of decent liquid intake among young sportpersons, especially during physical effort in a higher temperature around allows to limit the risk of dehydration and its negative consequences. Dehydration decreases effort abilities and makes the risk of occurring health problems.
One can observe a lot of differences in functioning thermoregulative organs in children’s and adult’s bodies. The speed of sweat production during physical effort is lower among children than among adults, but a spontaneous intake of liquid (according to a body mass)
I similar in both groups and sometimes even bigger among children.
Rational liquid intake among young athletes during long physical effort and after its end is essential. According to the scientists’ advice decent amount of liquid intake absorbed by young athletes during exercising should be during 1 hour: 1 ml on 1 kg on a body mass.
The clues concerning post- exercising period suggest providing the amount of about 4 ml of liquid on 1 kg of a body mass during 1 hour effort done. Sufficient liquid intake for a young athlete organism in post- exercising period is particularly important when a lot of competitions are planned in a relatively short period of time.
The choice of a sufficient drink for young athletes should consider their personal preferences as it would make it easier support the sufficient liquid intake and create desirable habits connected with human organism hydration.
