Pozdravljeni!
Zanima me kaj je vzrok veliki koncentraciji soli v izločenem potu pri naporu?
Pa ne morem letat okrog z belimi lisami na temnih majicah in dresih!
Hvala in LP;
Sebastjan

Brez zamere medo1977, ampak temu tvojemu vprašanju in komentarju le-tega sem se pa prav od srca nasmejala .
S potom se sol pač izloča in tu ni kaj dosti storiti, paziti moraš le na rehidracijo. Kar pa se belih lis na temnih majčkah tiče, ti pa svetujem, da si omisliš kakšno lepo svetlo kolekcijo in bodo tvoje težave kot bi mignil rešene. In tekači v takšnih dresih so tako čedni....

Saj imaš zdaj na televiziji kup reklam za dezodorante, ki NE puščajo slanih odtisov. Lahko pa tudi kaj oblečeš pod frak...

[raziskovalec]

Medo, ko boš bolj natreninal, boš puščal manj oz nič madežev, vsaj tako je bilo pri meni.

To je pri letalcih pogost pojav.Ampak menda gre za solni cvet,ki ima dobro ceno!

in potem se dehidrirane ženske lepijo nate, da moraš dobesedno zbezljat in potem spet švicaš, začaran krog!!! No, res ne vem, a tečeš zato, da boš opažen ali da boš kaj naredil zase? Pa kaj potem, če si malce lisaste sorte. V reklamah so vsi postavni dečki tako prešvicani, da je kar joj, pa se naše oči vseeno ustavijo na njih in teleščkih. Zdaj pa je dilema, ali boš tekel in švical ter bil posledično opažen ali pa boš lep in čist doma čepel?
Brez zamere.
Če ni švica, ni truda. In tudi ne efekta.

Kolegi hvala za super informacije, ki so res popestritev dneva po opravljenih treh disciplinah triatlona in košnji trave.
Mislim ne, da bi sedaj toliko motil estetski izgled soli na temni majici.....bolj sem ciljal na to ali morda zaužijem preveč soli, da mi telo izloča potem tako koncentriran polt?
Sicer ste pa siper s svojimi odgovori, veselje za brat .
Mejte se, čaw S!

Abstract

CONTEXT: Uncertainty exists regarding the effect of sustained sweating on sweat mineral-element composition. PURPOSE: To determine the effect of multiple hours of exercise-heat stress on sweat mineral concentrations. METHODS: Seven heat-acclimated subjects (6 males, 1 female) completed 5 x 60 min of treadmill exercise (1.56 m/s, 2% grade) with 20 min rest between exercise periods in 2 weather conditions (27 degrees C, 40% relative humidity, 1 m/s and 35 degrees C, 30%, 1 m/s). Sweat was collected from a sweat-collection pouch attached to the upper back during exercise bouts 1, 3, and 5. Mineral elements were determined by using inductively coupled plasma-emission spectrography. RESULTS: At 27 degrees C, sweat sodium (863 [563] microg/mL; mean [SD]), potassium (222 [48] microg/mL), calcium (16 [7]) microg/mL), magnesium (1265 [566] ng/mL), and copper (80 [56] ng/mL) remained similar to baseline over 7 h of exercise-heat stress, whereas sweat zinc declined 42-45% after the initial hour of exercise-heat stress (Ex1 = 655 [362], Ex3 = 382 [168], Ex5 = 355 [288] microg/mL, P < 0.05). Similar outcomes were observed for sweat zinc at 35 degrees C when sweat rates were higher. Sweat rate had no effect on sweat trace-element composition. CONCLUSIONS: Sweat sodium, potassium, and calcium losses during multiple hours of sustained sweating can be predicted from initial sweat composition. Estimates of sweat zinc losses, however, will be overestimated if sweat zinc conservation is not accounted for in sweat zinc-loss estimates.
