Njengomsubathi, kungenzeka ukuthi sezwa ngendima yamanzi ashukela ngemuva kokuqeqeshwa. Kodwa singase singaqapheli ukuthi ushukela nawo uyi-carbohydrate. Empeleni iwuhlobo olulula kakhulu lwe-carbohydrate futhi itholakala ngokwemvelo ekudleni okuningi, okuhlanganisa izithelo, imifino, ubisi, nemikhiqizo yobisi. Ngakho-ke, ingabe ilungele ubuhlungu?
Ayivimbeli izintambo zezicathulo
Kunolwazi oluningi oluphikisanayo mayelana namanzi ashukela, nakuba iqiniso liwukuthi akuwona umonakalo ngokwemvelo empilweni. Kubaluleke kakhulu ukucabangela ukuthi umzimba wenzani ngalokho esikudlayo, hhayi nje lokho esikudlayo.
Ukudla okunoshukela nesitashi okuphansi cishe kuwumqondo omuhle kulabo abahlezi futhi abangawugawuli kahle ushukela. Kodwa, kubantu abakhuthele kwezemidlalo futhi bahlale belungile, abanengozi ephansi yesifo senhliziyo, isifo sikashukela, nokukhuluphala, ushukela nama-carbohydrate akuwona ubuthi, kodwa kunalokho kuwuhlobo oluwusizo ngcono ukusebenza kwezemidlalo.
Nakuba okunye ukudla kukhawulela ama-carbohydrates, ushukela wangemva kokujima empeleni uyingxenye enkulu yokudla kwabasubathi. Wonke ama-carbohydrate, kuhlanganise noshukela, aguqulwa kalula abe yi-glucose. I-glucose engadingeki ngokushesha igcinwa kokubili emisipha nasesibindini njenge-glycogen. Uma singagcwalisi lezi zitolo ze-glycogen ngempumelelo, singaphelelwa uphethiloli. Ngenxa yalesi sizathu, abasubathi abaningi bathembele ekuphuzeni amanzi ashukela ngemva kokuzivocavoca ukuze bavuselele imisipha ngokusebenza okulandelayo.
Nokho, amanzi ashukela ngokwawo awavimbeli izintambo zezicathulo. Kungenzeka ukuqhubeka nokuba nobuhlungu bemisipha ngemva kokuzivocavoca.
kuthuthukisa amandla
Ukudla ushukela ngesikhathi sokuqeqeshwa kungaba nomthelela omkhulu esibindini. Kokubili i-glucose ne-sucrose kuthinta amazinga wamandla ngendlela efanayo, nakuba i-sucrose ibangela ukungakhululeki okuncane.
Uma uqhathanisa ukuthathwa kwesiphuzo sikashukela noma amanzi anoshukela, kukhona ithuba lokuthola amandla angama-30%. Okusho ukuthi, umuntu okwazi ukuzivocavoca amahora amathathu ngamanzi nje angafaka ushukela ihora elilodwa ngemuva kokuqala umsebenzi.
Iziphuzo zezemidlalo ezidume kakhulu ziyahlukahluka ekusebenzeni kwazo, kepha kuyalulekwa ukuthi ubheke lezo ezine-sucrose kuphela esikhundleni seziphuzo ezisebenza njengamanzi ashukela. Kubalulekile ukwazi ukuthi ukuthatha i-glucose noma i-sucrose kuvimbela ukuncipha kwe-glycogen esibindini, kodwa hhayi i-muscle glycogen ngesikhathi sokuzivocavoca.
