Ososayensi Bakha "Iphilisi Lokuzivocavoca" Langempela

Abaqeqeshi, abafundisi, kanye nezazi zokudla bathanda ukuthi "alikho iphilisi lomlingo lempumelelo" uma kukhulunywa ngokuchoboza izinhloso zakho zokwehlisa isisindo noma ukufaneleka. Futhi baqinisile-kepha okwamanje.

Ucwaningo olusha lukhombisa ukuthi ukucindezelwa kweprotheyini ethile, i-myostatin, yomibili ikhulisa imisipha futhi iholele ekuthuthukeni okukhulu empilweni yenhliziyo nezinso (okungenani kumagundane!), Ngokusho kocwaningo olwethulwe emhlanganweni we-American Physiological Society's 2017 Experimental Biology. Kungani lokho kukukhulu: Kusho ukuthi isayensi iyisinyathelo esisodwa sokusondela ekudaleni iphilisi langempela lokuzivivinya (okuthusa abaqeqeshi yonke indawo).

I-Myostatin ibalulekile ngoba inethonya elinamandla ekhonweni lakho lokwakha imisipha. Abantu abane-myostatin eningi banayo Ngaphansi imisipha, nabantu abane-myostatin encane banayo Okuningi isisindo semisipha. (I-ICYMI, uma unesisindo somzimba omncane kakhulu, ama-cals amaningi uwashisa, ngisho nalapho uphumule.) Ucwaningo lubonisa ukuthi abantu abakhuluphele bakhiqiza i-myostatin eningi, okwenza kube nzima ukuzivocavoca nokwakha imisipha, iwanamathele ohlotsheni lokukhuluphala ukuya phansi, ngokusho kwabacwaningi. (Kodwa lokho akusho ukuthi akufanele banyakaze; noma yikuphi ukuvivinya umzimba kungcono kunokungazivocavoci.)

Ocwaningweni, abacwaningi bazalanisa izinhlobo ezine ezihlukene zamagundane: amagundane anciphile futhi akhuluphele ngalinye linokukhiqizwa kwe-myostatin okungenamkhawulo, namagundane anciphile futhi akhuluphele angazange akhiqize noma iyiphi i-myostatin. Kokubili amagundane anciphile futhi akhuluphele angakwazanga ukukhiqiza amaprotheni athuthukisa imisipha eminingi, yize amagundane akhuluphele ahlala ekhuluphele. Kodwa-ke, amagundane akhuluphele akhombisa nezimpawu zempilo zenhliziyo nemithambo yegazi ebezihambisana nozakwabo abanciphile futhi bezingcono kakhulu kunamagundane akhuluphele ane-myostatin eningi. Ngakho-ke noma amazinga abo amafutha engashintshi, babenemisipha eminingi ngaphansi amanoni futhi awakhombisanga ezinye zezinto ezinobungozi obukhulu bokukhuluphala. (Yebo, "ukhuluphele kodwa ulungele" empeleni kunempilo.)

Ukuhlanganisa amandla e-myostatin kubalulekile ngaphezu kokuncipha kwesisindo. Lokhu okutholakele kusikisela ukuthi ukuvimba amaprotheni kungaba yindlela ephumelelayo yokusheshisa ukulandelela izinzuzo ezivikelayo zenhliziyo nemithambo yegazi yokuba nemisipha ethambile (ngaphandle kokuyakha ejimini), futhi uvimbele noma uhlehlise (!!) okuhlobene nokukhuluphala ngokweqile izinguquko ekusebenzeni komzimba wakho, izinso, nokusebenza kwenhliziyo. (Uma sikhuluma ngokuhlehla, bewazi ukuthi i-HIIT iwukuzilolonga okuphelele kokulwa nokuguga?)

Ngokusobala, ukuphuma ngephilisi ngalezi zinzuzo ngeke kukunikeze * konke * izinzuzo ozithola kuseshini yangempela yokujuluka. Ngeke kwandise ukuguquguquka kwakho noma i-zen ngendlela i-yoga eyenza ngayo, ikunikeze umgijimi omuhle kakhulu, noma ikushiye ngalowo mqondo wokunikwa amandla onawo ngemuva kokuphakamisa izinsimbi. Uqinisekile ukuthi isihogo asikwazanga nje ukuvula amaphilisi athile futhi silindele ukukwazi ukuqhuba umncintiswano. I-Myostatin ingakusiza Yakha imisipha, kodwa ukuqeqesha lowo msipha kungenye into. Ngakho-ke, yebo, ukusebenzisa i-myostatin powerhouse entsha ngohlobo oluthile lwesengezo kungahle kukhulise imiphumela yakho yokuzivocavoca futhi kusize ukukhuphula abantu abakhuluphele nokuhamba, kepha ngeke kuze kuthathe isikhundla somsebenzi onzima wakudala.

Isizathu esengeziwe sokufika ejimini: Ungangena kumlingo we-myostatin ngaphandle kokulinda iphilisi eliqhekezayo. Ucwaningo lubonisa ukuthi kokubili ukumelana nokuzivocavoca kwe-aerobic kungase kubangele ukwehla okukhulu kwe-myostatin emisipha yamathambo. I-#SorryNotSorry-myostatin isiphumile ngokusemthethweni ohlwini lwakho lwezizathu zokweqa ijimu namuhla.
