Kab lus muab cov ntaub ntawv siv tau thiab muaj txiaj ntsig zoo txog qhov tseem ceeb amino acid li leucine. Koj yuav kawm paub yog vim li cas cov leeg nqaij anabolism ua tsis tau yam tsis muaj nws. Cov ntsiab lus ntawm tsab xov xwm:

  • Kev cuam tshuam rau kev ua haujlwm tau zoo
  • Tawm tsam qhov hnyav tshaj
  • Kev nyab xeeb hauv kev siv

Cov ntsiab lus tseem ceeb uas ua rau txhua cov protein hauv lub cev yog cov amino acids. Tsis ntev dhau los nws tau hloov pauv tias lawv tseem tsim cov phiaj xwm kev qhia ntawm anabolism. Kev noj zaub mov sib xyaw ua rau muaj protein ntau biosynthesis hauv cov leeg pob txha. Leucine, valine thiab isoleucine tau muab cais ua BCAA branched chain amino acids. Protein tau muab coj los ua qhov tseeb vim tias lawv siv zog ua. Kev tshawb fawb tshawb fawb uas cuam tshuam txog niaj hnub no, cov ntsiab lus uas yog BCAAs thiab feem ntau yog leucine, yuav yog lub ncauj lus ntawm kab lus hnub no.

Ntawm txhua qhov BCAAs paub txog, leucine tau lees paub tias yog qhov ua tau zoo tshaj plaws. Kev nce qib ntawm cov amino acid no tom qab noj mov dhau los ua lub cim qhia kev noj zaub mov uas ua rau muaj protein ntau biosynthesis hauv cov leeg. Cov no yog cov lus xaus los ntawm cov kws tshawb fawb los ntawm Baylor College of Medicine raws li kev tshawb fawb. Lub hom phiaj ntawm ib qho ntawm no yog qhov cuam tshuam ergogenic tshwm sim los ntawm kev ntxiv leucine.

Cov kws tshawb fawb tau coj los ntawm Dr. Crowe. Ib pawg kws tshawb fawb tau ua tib zoo saib yuav ua li cas thiaj li tau txais cov amino acid no cuam tshuam rau kev ua tau zoo ntawm kev cob qhia canoeists. Txoj kev tshawb fawb pom tias peb caug tus neeg ncaws pob tau noj cov amino acid ntawm tus nqi ntawm 45 mg / kg lub cev hnyav lossis cov placebo. Qhov kev sim ntawd tau ntev txog rau lub lis piam. Nws tau pom tias cov amino acid cuam tshuam rau kev tsim khoom ntawm lawv txoj haujlwm.

Kev noj leucine tau pom los txhim kho kev ua siab ntev hauv cov kis las nrog rau cov leeg muaj zog hauv lub cev. Cov koom haum ntawm txoj kev tshawb fawb tau nthuav tawm ib qho version: qhov ua rau ergogenic cuam tshuam nrog kev noj cov amino acid, hauv lawv qhov kev xav, yog vim qhov txo qis hauv qib ntawm kev puas tsuaj rau cov nqaij leeg pob txha. Cov kev raug mob no tuaj yeem tshwm sim los ntawm kev qhia ua kom muaj zog.

Muaj pov thawj tias kev noj BCAAs ua ntej kev kawm tuaj yeem txo qis cov protein tawg hauv cov leeg tom qab tawm dag zog. Ib qho ntxiv, leucine thiab pob txha pob txha anabolism muaj feem cuam tshuam nrog. Muaj cov ntaub ntawv hais tias cov leeg qaug zog tom qab kev kawm tau raug txo los ntawm kev noj BCAAs ua ntej kev tawm dag zog. Qhov no txhawb nqa kev rov zoo thaum ntxov.

Leucine tiv thaiv qhov hnyav tshaj

Kev noj zaub mov muaj protein ntau, thaum tseem muaj cov carbohydrates qis, ua rau poob phaus. Hnub no nws tsis yog qhov zais rau leej twg. Cov txheej txheem kev noj zaub mov no cuam tshuam rau kev hlawv roj yam tsis tau tawm hauv chav rau cov nqaij ntshiv nqaij kom poob hauv txoj kev.

Tus nqi ntawm cov calories noj thaum nruab hnub tsis cuam tshuam qhov no txhua qhov, uas tau pom los ntawm ntau yam kev sim. American Journal of Clinical Nutrition tau tshaj tawm cov txiaj ntsig ntawm kev kawm piv txwv. Lawv kuj tau lees paub qhov tseem ceeb ntawm leucine hauv kev poob phaus.

Ib qho tshwm sim hauv kab lus uas leucine yog lub hauv paus tseem ceeb ntawm kev noj zaub mov zoo ib yam. Ib qho zoo sib xws tau tshwm sim vim qhov tshwj xeeb ntawm cov amino acid tau kawm. Leucine tau pom tias yog qhov tseem ceeb thaum cov leeg loj hlob nyob rau hauv kev cuam tshuam ntawm kev tswj cov kab mob hauv lub cev thiab hauv kev rov ua cov piam thaj los ntawm alanine.

Lub hauv paus no tswj hwm li cas cov piam thaj raug hlawv los ntawm cov leeg pob txha. Ib lub tswv yim tseem ceeb ua rau nws muaj peev xwm khaws cov leeg nqaij, thaum pab tswj kom cov ntshav qab zib nyob ruaj khov nrog kev noj zaub mov txawv rau lub cev.

Leucine ua lub luag haujlwm tseem ceeb thaum nws los khaws cia cov nqaij protein. Txawm li cas los xij, qhov no tsis yog qhov laj thawj nkaus xwb tom qab cov txheej txheem ua kom muaj zog ntawm cov zaub mov muaj protein ntau. Cov qib insulin poob qis dua vim qhov txo qis hauv kev noj cov carbohydrates. Qhov no qhia txog cov roj visceral kom khaws cov nqaij rog.

Dr. Matthias Blucher, ntawm Tsev Kawm Kho Mob Harvard, tsim muaj qhov tsis txaus ntawm cov yam ntxwv ua kom cov insulin tau txais cov insulin hauv nas hauv chav kuaj. Qhov kev paub no tau qhia tias kev tiv thaiv tiv thaiv qhov hnyav dhau tuaj yeem muab los ntawm kev tsim cov tshuaj insulin tsis txaus nyob hauv cov rog rog.

Yog li, nas tsuag tuaj yeem noj zaub mov yam tsis tau hnyav. Nws dhau los ua qhov tseeb uas tau piav qhia cov tshuaj hormones ua lub luag haujlwm tseem ceeb hauv kev hnyav ntau dua. Tus nqi ntawm cov calories noj tsis muaj teeb meem.

Cov tsiaj protein muaj 2: 1: 1 piv ntawm leucine, isoleucine thiab valine. Yog tias koj pom qhov sib piv zoo sib xws, cov amino acids no muaj kev nyab xeeb kiag li. Qhov no tau raug pov thawj los ntawm kev sim tshuaj lom BCAAs uas cov tsiaj tau koom nrog.

Saib cov vis dis aus txog BCAAs:

Vim li cas thiaj siv cov amino acids no? Vim lawv functionality. Lawv nyob ntawm qhov siab ntawm kev lees paub tas li. Peb twb paub qhov kev xav ntawm cov kws tshawb fawb. Kev noj cov BCAAs thiab tshwj xeeb tshaj yog leucine muaj qhov cuam tshuam rau kev tawg ntawm cov leeg nqaij, thaum ua kom yooj yim rau cov txheej txheem ntawm anabolism. Los ntawm kev ntsuas cov tshuaj amino acid, koj tuaj yeem txuag cov leeg nqaij thiab tswj cov ntshav qab zib thaum noj zaub mov qis.
