"Kuwedzerwa kweKonjac glucomannan (KGM) kunoita senzira yakakosha yekurapa yekuderedza kuvimbiwa, nenzira inogona kushandiswa kuburikidza nekuwedzera kusiyana-siyana uye kushanda kwe microbiota yemudumbu," vakanyora kudaro masayendisiti vekuSouthwest University muChina muEuropean Journal of Nutrition. "Mhedzisiro iyi inotsigirawo kugona kwekurapa kwefiber mukugadzirisa mamiriro emudumbu nekuvandudza hutano hwemudumbu, kunyanya muvatambi."
Kuzvimba kunofungidzirwa kuti kunobata vanhu vakuru vanosvika 20%, dambudziko iri richinyanya kuitika pakati pevatambi.
Sekureva kwechinyorwa chitsva ichi, kurovedza muviri kwakasimba kunogona kuderedza kuyerera kweropa mudumbu, nokudaro kuchideredza kufamba kwaro. Kudya zvine mapuroteni akawanda, zvisina fiber yakawanda kunogonawo kuwedzera kufamba kwedumbu, uye kupera mvura mumuviri kunogona kuita kuti zvinhu zvinyanye kuipa.
Izvi zvakaita kuti vamwe vaongorori vaongorore kana fiber inonyungudika mukudya, yakadai sekonjac glucomannan (KGM), ichigona kugadzirisa zviratidzo zvekuvimbiwa. Dzimwe ongororo dzinoratidza kuti KGM inogona kuvandudza huwandu hwemvura mutsvina, kudzora kuumbwa kwe microbiota mudumbu, uye kukurudzira kufamba kwemudumbu.
"Zvisinei, ruzivo rwekiriniki ruchiri rushoma muvanhu, kunyanya pakati pevatambi vepamusoro," masayendisiti akanyora kudaro.
Kuedzwa uku kutsva kwakaitwa nevatambi veTaekwondo vevarume vane hunyanzvi hwepamusoro-soro vairwara nekuzvimba kwemuviri. Vatambi vakakamurwa kuita mapoka maviri: boka rimwe rakapihwa mushonga we placebo (3 gramu yemaltodextrin pazuva), rimwe boka rakapihwa KGM (3 gramu pazuva) kwemavhiki masere.
Zvakawanikwa zvakaratidza kuti zvichienzaniswa ne placebo, nzira dzakasiyana-siyana dzekuongorora kuvimbiwa dzakavandudzwa zvikuru, kusanganisira kuongororwa kwezviratidzo zvekuvimbiwa nemurwere (PAC-SYM), kuongororwa kwehupenyu hwemurwere hwekudzivirira kuvimbiwa (PAC-QoL), mafambiro ekufamba kwemudumbu (BMF), uye chiyero chebasa remudumbu (BFI).
Ongororo ye microbiome yakaratidza kuti KGM yakawedzera α-diversity uye huwandu hwemarudzi akasiyana-siyana, kusanganisira *Lactobacillus*, *Bacteroides*, uye *Phascolarctobacterium*. Kusiyana neizvi, huwandu hwe *Alistipes* ne *Desulfovibrio* hwakaderera.
Zvakabuda zvakaratidza kuti shanduko mu microbiota yemudumbu dzaive dzakabatana zvakanyanya nekuvandudzika kwezviratidzo zvekuvimbiwa. Ongororo yakawedzerwa yakaratidza shanduko munzira dzakasiyana siyana dzekugadzirisa muviri, kunyanya idzo dzinobatanidzwa mukugadzirwa kwe biotin uye kuderedza nitrate.
Vaongorori vakashuma kuti: “Sekuziva kwedu, iyi ndiyo ongororo yekutanga muvanhu vanotamba mitambo inoratidza kuti KGM inogona kuderedza zviratidzo zvine chekuita nekuvimbiwa nekuchinja chimiro che microbiota yemudumbu. Izvi zvinoratidza kuti kuchinja kwe microbiota yemudumbu kungave nzira huru iyo fiber yekudya inoshandisa mhedzisiro yayo pakurapa kwemudumbu.”
Vakagumisa vachiti: "Zvakawanikwa izvi zvinopa humbowo hwakasimba hwekuti kuwedzerwa kwefiber mukudya kunogona kuitika pakurapa kuvimbiwa uye zvinoratidza kuti zvinogona kushandiswa semushonga usiri wemishonga wekusashanda zvakanaka kwemudumbu muvatambi."

Creatine yave iri chinhu chakakosha mumitambo kubvira kuma1990, ichishandiswa zvakanyanya kuvandudza mashandiro emhasuru uye kuumbwa kwemuviri panguva yekurovedza muviri nemakwikwi. Zvisinei, mhedzisiro yecreatine pavatambi vemitambo yekurwa vanofanirwa kuchengetedza huremu hwakati wandei haisati yajeka.
Ongororo itsva inoratidza kuti varwi vepamusoro vanogona kuvandudza mashandiro avo emitambo nekutora mishonga yekuwedzera yemunhu mumwe nemumwe kana yakasanganiswa.
Ongororo yakaitwa mumakonzo munguva pfupi yapfuura yakawana kuti glucomannan, chirimwa chinobva kuAsia chinowanikwa mukonjac, chinogona kubatsira pahutano hwechiropa.
