Ophunzitsa, alangizi, ndi akatswiri azakudya amakonda kunena kuti "palibe mapiritsi amatsenga opambana" ikafika pakuphwanya zolinga zanu zochepetsera thupi kapena zolimbitsa thupi. Ndipo akulondola, koma pakadali pano.

Kafukufuku watsopano akuwonetsa kuti kuponderezedwa kwa puloteni inayake, myostatin, kumapangitsa kuti minofu ikhale yolimba ndipo imapangitsa kuti pakhale kusintha kwakukulu kwa thanzi la mtima ndi impso (osachepera mbewa!), Malinga ndi kafukufuku woperekedwa pa msonkhano wa American Physiological Society's 2017 Experimental Biology. Chifukwa chake ndizachikulu: Zimatanthawuza kuti sayansi ndi gawo limodzi loyandikira kupanga mapiritsi olimbitsa thupi (kukhumudwitsa ophunzitsa kulikonse).

Myostatin ndiyofunikira chifukwa imakhudza kwambiri luso lanu lopanga minofu. Anthu omwe ali ndi myostatin ambiri ali nawo Zochepa minofu, ndipo anthu omwe ali ndi myostatin yocheperako ali nawo Zambiri minofu. (ICYMI, minofu yochuluka kwambiri yomwe mumakhala nayo, mumawotcha kwambiri, ngakhale mutapuma.) Kafukufuku akuwonetsa kuti anthu onenepa kwambiri amapanga myostatin yambiri, zomwe zimapangitsa kuti zikhale zovuta kuchita masewera olimbitsa thupi ndikumanga minofu, ndikuwaphatika ngati kunenepa kwambiri kutsika, malinga ndi ofufuza. (Koma izi sizikutanthauza kuti sayenera kusuntha; kuchita masewera olimbitsa thupi kuli bwino kuposa kusachita masewera olimbitsa thupi.)

Pakafukufuku, ofufuza adapanga mbewa zinayi zosiyanasiyana: mbewa zowonda komanso zonenepa iliyonse imakhala yopanda malire ya myostatin, ndi mbewa zowonda komanso zonenepa zomwe sizinatulutse myostatin iliyonse. Onse mbewa zowonda komanso zonenepa zomwe sizikanapanga puloteniyo zidapanga minofu yambiri, ngakhale mbewa zonenepazo zidakhalabe zonenepa. Komabe, mbewa zonenepa kwambiri zidawonetsanso thanzi lamtima ndi kagayidwe kachakudya komwe kunali kofanana ndi anzawo owonda ndipo anali abwinoko kuposa mbewa zonenepa ndi myostatin yambiri. Kotero ngakhale kuti mafuta awo sanasinthe, anali ndi minofu yambiri pansi mafuta ndipo sanasonyeze zina zazikulu chiopsezo zinthu kukhala onenepa. (Inde, kukhala "wonenepa koma woyenera" kulidi wathanzi.)

Kugwiritsa ntchito mphamvu ya myostatin ndikofunikira kuposa kungochepetsa thupi. Zotsatira izi zikusonyeza kuti kutsekereza puloteniyo kungakhale njira yabwino yofulumizitsira chitetezo chamtima chokhala ndi minofu yowonda kwambiri (popanda kuyimangirira ku malo ochitira masewera olimbitsa thupi), komanso kupewa kapena kusinthanso (!!) kusintha kwa kagayidwe kanu, impso, ndi mtima. (Kunena zosintha, kodi mumadziwa kuti HIIT ndiye masewera olimbitsa thupi oletsa kukalamba?)

Zachidziwikire, kutulutsa piritsi ndi izi sikungakupatseni zabwino zonse zomwe mumapeza kuchokera thukuta lenileni. Sizingakulitse kusinthasintha kwanu kapena momwe yoga imachitira, kukupatsani wothamanga wabwino, kapena kukusiyani mphamvu yakupezera mphamvu mukamakweza. Mukutsimikiza kuti helo sangangotulutsa mapiritsi ena ndikuyembekeza kuti mutha kuthamanga marathon. Myostatin ikhoza kukuthandizani mangani minofu, koma kuphunzitsa minofu ndi chinthu china chonse. Chifukwa chake, inde, kugwiritsa ntchito mphamvu yamagetsi yatsopano ya myostatin kudzera mumtundu wina wowonjezera kungalimbikitse zotsatira zanu zolimbitsa thupi ndikuthandizira anthu onenepa kwambiri kusuntha, koma sizidzasinthiranso ntchito yakale.

Chifukwa chinanso chopitira ku masewera olimbitsa thupi: Mutha kulowa mumatsenga a myostatin osadikirira mapiritsi owopsa. Kafukufuku amasonyeza kuti kukana komanso kuchita masewera olimbitsa thupi kungayambitse kuchepa kwakukulu kwa myostatin mu minofu ya chigoba. # SorryNotSorry-myostatin wachotsedwa pamndandanda wazifukwa zomwe muyenera kudumpha masewera olimbitsa thupi lero.
