“Ukwengezwa kwe-Konjac glucomannan (KGM) kubonakala kuyindlela ebalulekile emtholampilo yokunciphisa ukuqunjelwa okusebenzayo, kanti indlela engaba khona iwukuthuthukisa ukuhlukahluka kanye nokusebenza kwe-gut microbiota,” kubhala ososayensi baseSouthwest University eShayina kuyi-European Journal of Nutrition. “Le miphumela isekela kakhulu amandla okwelapha e-fiber ekudleni ekulawuleni uhlelo lwe-ecosystem yamathumbu kanye nokuthuthukisa impilo yamathumbu, ikakhulukazi kubadlali.”
Kulinganiselwa ukuthi ukuqunjelwa kuthinta abantu abadala abangafika ku-20%, kanti le nkinga ivame kakhulu phakathi kwabadlali.
Ngokusho kwalesi sihloko esisha, ukuvivinya umzimba ngamandla kunganciphisa ukugeleza kwegazi endleleni yokugaya ukudla, ngaleyo ndlela kunciphise ukuhamba kwegazi. Ukudla okunamaphrotheni amaningi, okune-fiber ephansi nakho kungandisa ukuhamba kwegazi emathunjini, futhi ukuphelelwa amanzi emzimbeni kungenza izinto zibe zimbi kakhulu.
Lokhu kuye kwashukumisela abanye abacwaningi ukuthi bahlole ukuthi i-fibre yokudla encibilikayo, njenge-konjac glucomannan (KGM), ingazithuthukisa yini izimpawu zokuqunjelwa. Ezinye izifundo ziphakamisa ukuthi i-KGM ingathuthukisa okuqukethwe kwamanzi endle, ilawule ukwakheka kwe-microbiota yamathumbu, futhi ikhuthaze ukunyakaza kwamathumbu.
“Kodwa-ke, idatha yezokwelapha isalokhu ilinganiselwe kubantu, ikakhulukazi phakathi kwabadlali abaphambili,” kubhala ososayensi.
Lolu vivinyo olusha olulawulwayo olungaboni kahle, olungahleliwe, luhilele abadlali be-taekwondo besilisa abangama-48 abahlushwa ukuqunjelwa okusebenzayo. Abagijimi bahlukaniswe ngokungahleliwe baba amaqembu amabili: iqembu elilodwa lathola i-placebo (amagremu ama-3 e-maltodextrin nsuku zonke), kanti elinye iqembu lathola i-KGM (amagremu ama-3 nsuku zonke) amasonto ayisishiyagalombili.
Imiphumela ibonise ukuthi uma kuqhathaniswa ne-placebo, izindlela eziningana zokulinganisa ukuqunjelwa zithuthuke kakhulu, okuhlanganisa ukuhlolwa kwesiguli kwezimpawu zokuqunjelwa (i-PAC-SYM), ukuhlolwa kwesiguli kwekhwalithi yokuphila kokuqunjelwa (i-PAC-QoL), imvamisa yokuhamba kwamathumbu (i-BMF), kanye nenkomba yokusebenza kwamathumbu (i-BFI).
Ukuhlaziywa kwe-microbiome kwembule ukuthi i-KGM yandisa ukuhlukahluka kwe-α kanye nobuningi obuhlobene bezinhlobo ezahlukene, okuhlanganisa *i-Lactobacillus*, *i-Bacteroides*, kanye *ne-Phascolarctobacterium*. Ngokuphambene nalokho, ukugcwala kwe-*Alistipes* kanye *ne-Desulfovibrio* kwehlile.
Imiphumela ikhombisile ukuthi izinguquko ku-gut microbiota zihlobene eduze nezimpawu zokuqunjelwa ezithuthukisiwe. Ukuhlaziywa okwengeziwe kwembule izinguquko ezindleleni eziningana ze-metabolic, ikakhulukazi lezo ezihilelekile ku-biotin biosynthesis kanye nokunciphisa i-nitrate.
Abacwaningi babike: “Ngokwazi kwethu, lolu ucwaningo lokuqala kubadlali abangabantu olubonisa ukuthi i-KGM inganciphisa izimpawu ezihlobene nokuqunjelwa ngokushintsha ukwakheka kwe-gut microbiota. Le miphumela iphakamisa ukuthi ukuguqulwa kwe-gut microbiota kungaba yindlela eyinhloko lapho i-fiber yokudla iveza khona imiphumela yayo yokwelapha ekusebenzeni kwesisu.”
Baphetha ngokuthi: “Le miphumela inikeza ubufakazi obuqand’ ikhanda bokuthi kungenzeka yini ukuthi kusetshenziswe i-fiber yokudla ekwelapheni ukuqunjelwa okusebenzayo futhi iqokomisa amandla ayo njengokwelashwa okungekhona okwemithi kokungasebenzi kahle kwamathumbu kubasubathi.”

I-Creatine ibilokhu iyisici esibalulekile kwezemidlalo kusukela ngawo-1990, isetshenziswa kabanzi ukuthuthukisa ukusebenza kwemisipha kanye nokwakheka komzimba ngesikhathi sokuqeqeshwa kanye nokuncintisana. Kodwa-ke, imiphumela ye-creatine kubasubathi be-karate okudingeka balondoloze isigaba esithile sesisindo ayikacaci.
Ukuhlaziywa okusha kwe-meta kusikisela ukuthi abadlali be-elite fighters bangathuthukisa ukusebenza kwabo kwezemidlalo ngokuthatha izithasiselo zomuntu ngamunye noma ezihlanganisiwe.
Ucwaningo lwamuva nje oluye lwenziwa emagundwini luthole izinzuzo ezingaba khona zempilo yesibindi ezivela ku-glucomannan, isitshalo esidabuka e-Asia futhi esitholakala ku-konjac.
