Izihlunu zakho zikushiya njengoko ukhula! Ukuba awuwakhi umsipha, uya kuba nobunzima ngakumbi kunabanye, kwaye ukuhlala ixesha elide kuya kudala "isangqa sokubhukuda." Abantu abakubudala obuphakathi nabasele bekhulile, njengabazali nootatomkhulu noomakhulu, badla ngokuvakalelwa kukuba amalungu abo omzimba abuthathaka yaye bayasokola ukunyuka izinyuko, nto leyo ekwabangelwa kukuphelelwa yicalcium ngenxa yobudala, nto leyo ephumela ekubeni babe neengxaki zamathambo. Kwafunyaniswa ukuba iHMBCa inokusombulula ezi ngxaki. Kwisihlwele somzimba, sinokubonelela ngesondlo sempilo yemisipha. Kubantu abaneminyaka ephakathi kunye nabantu abadala banokunceda ukukhusela i-osteoporosis, ukubola kwemisipha; I-HMBCa ikwabizwa ngokuba yi "muscle maker".

Ukongeza, izifundo zonyango ziye zafumanisa ukuba i-HMBCa inokunceda abantu abanamathumba babuyisele impilo yemisipha.

Izifundo zibonise ukuba ukongezwa kwe-3 grams ngosukuicalcium beta-hydroxy-beta-methylbutyrate (HMB), i-metabolite yendalo ye-amino acid leucine ebalulekileyo yomzimba, inokunqanda okanye ide ibuyisele ukulahleka kwemisipha yamathambo. Umzimba womntu unokuvelisa ngokwemvelo, unokufumaneka kwindalo (njengenyama yenkomo, amaqanda, i-broccoli, njl.), kodwa ingumkhondo, ukuze kugcinwe impilo ye-muscle yezigulane ezinomhlaza, okanye kufuneka zongezwe yi-HMB exogenous.

Yintoni iHMBCa

I-HMB ifumaneka ngokubanzi kwiziqhamo ze-citrus, imifuno ethile efana ne-broccoli, i-legumes efana ne-alfalfa, kunye neentlanzi ezithile kunye nokutya kwaselwandle. Kwimveliso yoshishino, ukwenzela ukuba kube lula ukugcinwa kunye nokusetyenziswa, i-HMB idla ngokuguqulelwa kwiityuwa ze-calcium ngexesha lokuhlanganiswa, ehlala isetyenziswa kwi-monohydrate, eyi-β-hydroxy-β-methylbutyrate calcium monohydrate.

I-HMB yi-metabolite esebenzayo ye-leucine yesebe eyimfuneko ye-amino acid leucine, enokukhuthaza ukuhlanganiswa kweprotheni kunye nokunciphisa ukuphuka kwayo, ngokwandisa amandla omzimba womntu, ukulibazisa ukudinwa kwemisipha, kunye nokunceda ukukhusela i-muscle atrophy kubantu abadala.

Ukusukela ngo-2011, ukutya okukrwada okutsha kwe-HMB? kukhathazwa kakhulu ngamashishini okutya asekhaya. Kwi-2017, iKomishoni yeSizwe yezeMpilo kunye noCwangciso lweNtsapho yazisa ukwandiswa kobubanzi besicelo se-HMB? ukusuka kwizicelo ezimbini zokuqala ukuya kwisithoba.

Isicelo seHMBCa

1. Indlela yokusebenza kunye nokhuseleko lweHMBCa

I-Beta-hydroxy-beta-methylbutyric acid (HMB) yi-metabolite ye-leucine. I-branched chain amino acids zenza ngaphezu kwe-30% yeprotheyini kwi-muscle, phakathi kwayo i-leucine iyona kuphela i-amino acid enokulawula i-protein ye-protein kwi-skeletal muscle kunye ne-heart muscle, enokulawula ukuhlanganiswa kwe-muscle, ukukhusela i-protein degradation kunye nokubuyiselwa kokulimala kwezemidlalo.

I-HMBCa yenye yeendlela eziqhelekileyo ezihambelanayo ze-HMB, kwaye yinto entsha yokutya ekrwada evunywe liSebe lezeMpilo e-China, kwaye ukhuseleko lwayo luye lwafundwa ngokubanzi. Kwizifundo zomntu, i-6gHMB yemihla ngemihla ayifumanekanga ukuba nayo nayiphi na impembelelo kwi-cholesterol, i-hemoglobin, iiseli ezimhlophe zegazi, amanqanaba eshukela egazi, isibindi kunye nokusebenza kwezintso emva kwenyanga ye-1 yokusetyenziswa. U-Baier wafunda ukusetyenziswa kwansuku zonke kwe-2 kwi-3gCaHMB kunye nomxube we-amino acid kubantu abadala, kwaye akukho tshintsho lufunyenwe kwigazi lesibindi kunye nezintso kunye negazi le-lipids emva kwe-1 unyaka wokusetyenziswa.

2. Ukusetyenziswa kwe-HMBa kwisondlo sezilwanyana

Uphononongo lubonise ukuba ukusetyenziswa kwe-HMBCa kwiinkukhu zenyama kunokuphucula ukusebenza kokukhula kunye nokwandisa umxholo wenyama ebhityileyo, ukuze kwandiswe ngokufanelekileyo isivuno senyama, kunye nokongezwa kwe-HMBCa yokutya kunokuphucula ukukhula kwemfuyo kunye neenkukhu kunye nokuphucula ukugonywa kwezilwanyana.

UGuo Junqing et al. ezikhethiweyo ezinempilo Inner Mongolia iibhokhwe zoboya obumhlophe kwaye zongeza imilinganiselo eyahlukeneyo ye-HMBCa kunye ne-leucine kwi-basal diet. Iziphumo zibonise ukuba ukongezwa kwe-leucine kunye ne-HMBCa ekudleni kunokunyusa umxholo we-serum lysozyme, ukwandisa umxholo we-serum immunoglobulin kunye nokuphucula umsebenzi wokuzivikela womzimba.

3. Ukusetyenziswa kwe-HMBa kwisondlo sezemidlalo

Uphononongo lubonise ukuba ukusebenzisa i-calcium beta-hydroxy-beta-butyrate emva kokuzilolonga akunakukhawulezisa ukulungiswa kwezicubu zomzimba kuphela, kodwa nokukhuthaza ukukhula komthamo we-muscle, ukwandisa ukunyamezela, kunye nokuphucula amandla.

Ngo-Oktobha 2013, i-International Society of Sports Nutrition (ISSN) yenze uhlalutyo olunzulu kunye neenkcukacha zoncwadi kwi-HMB njengesongezelelo sesondlo kwaye yenza le nkcazo elandelayo. ① Ngokwenza umthambo owenziwe ngokulimala kwamathambo kubantu abaqeqeshiweyo nabangaqeqeshwanga, i-HMB inokunciphisa ukulimala kwemisipha kunye nokukhuthaza ukubuyiswa. Iimbaleki ziya kuxhamla kuqeqesho kunye nokuxhaswa nge-HMB. ③ Yongeza i-HMB ngaphambi kokuzilolonga kwiiveki ezi-2 ukuze ufumane iziphumo ezingcono. Ukuzivocavoca okufanelekileyo kubantu abaqeqeshiweyo okanye abangaqeqeshwanga, kunye ne-supplement yemihla ngemihla ye-38mg / kg · BMI ye-HMB, inokukhuthaza ukukhula kwemisipha kunye nokwandisa amandla omzimba kunye namandla. Iimpembelelo ze-HMB ziquka ukuthotywa kweeprotheyini ezincitshisiweyo kunye nokunyuka kweeprotheni synthesis.

4. Ukusetyenziswa kwe-HMBa ekutyeni olungumgubo ngeenjongo zonyango ezizodwa

Ukutya kwefomula ngeenjongo zonyango ezikhethekileyo kunokubaluleka okubalulekileyo kwezonyango ekulungiseni ukungalingani kwemetabolism, ukunciphisa iingxaki ezinjengosulelo, ukuqinisa impembelelo yeendlela ezahlukeneyo zonyango, ukukhuthaza ukuchacha, ngaloo ndlela kufinyezwa ukuhlala esibhedlele kunye nokuphucula umgangatho wobomi bezigulana.
