Koj tuaj yeem sau cov txiaj ntsig ntawm kev ua si li cas hauv txoj kev zoo?

Cov kws tshawb fawb ntawm Baylor thiab Stanford Colleges of Medicine thiab lawv cov koom haum sib koom ua ke tau tshaj tawm hauv tsab ntawv tshaj tawm hauv Xwm "Lawv muaj peev xwm txheeb xyuas cov molecule hauv cov ntshav uas tau tsim thaum lub sijhawm ua haujlwm thiab tuaj yeem txo cov khoom noj thiab rog rog hauv cov nas.

Raws li Neuroscience News, qhov kev tshawb pom tshiab tuaj yeem pab txhim kho cov kws tshawb fawb kev nkag siab txog cov txheej txheem physiological uas ua rau muaj kev cuam tshuam ntawm kev tawm dag zog thiab txo kev tshaib kev nqhis.

txo cov rog rog

"Kev qoj ib ce tsis tu ncua tau pom tias yuav pab kom poob phaus, tswj kev noj qab haus huv thiab txhim kho cov metabolism, tshwj xeeb tshaj yog rau cov neeg rog rog thiab rog," hais tias kev tshawb fawb co-sau Dr.

"Yog tias peb (cov kws tshawb fawb) tuaj yeem nkag siab txog cov txheej txheem los ntawm kev tawm dag zog ua rau cov txiaj ntsig no, peb tau ze dua los pab ntau tus neeg txhim kho lawv txoj kev noj qab haus huv," nws hais ntxiv.

"Kev nkag siab tias kev tawm dag zog ua haujlwm li cas ntawm qib molecular yuav ua rau peb muaj peev xwm sau tau qee yam ntawm nws cov txiaj ntsig," said co-sau xibfwb Jonathan Long, tus pab xibfwb ntawm pathology ntawm Stanford Medicine thiab tus kws tshawb fawb ntawm Stanford Chem-H Institute.

Cov laus thiab cov tsis muaj zog

"Piv txwv li, cov neeg laus lossis cov neeg qaug zog uas tsis tuaj yeem tawm dag zog txaus yuav muaj ib hnub tau txais txiaj ntsig los ntawm kev noj cov tshuaj uas tuaj yeem pab qeeb pob txha, mob plawv, lossis lwm yam mob," nws hais ntxiv.

Amino acids

Xu, Ntev thiab lawv cov npoj yaig tau ua tiav kev soj ntsuam ntawm cov ntshav plasma tebchaw los ntawm cov nas tom qab khaus khiav ntawm lub treadmill. Qhov feem ntau catalytic molecule yog hloov kho amino acid hu ua Lac-Phe. Nws yog tsim los ntawm lactate, uas yog ib tug byproduct ntawm strenuous ce, uas ua rau lub "hlwb" hnov ​​nyob rau hauv cov leeg, thiab phenylalanine, ib tug amino acid uas yog ib tug ntawm cov tsev blocks ntawm proteins.

qabzib kam rau ua

Cov nas rog rog tau muab cov zaub mov muaj roj tsawg txo cov khoom noj los ntawm kwv yees li 50% piv rau kev tswj cov nas nyob rau lub sijhawm 12-teev, tsis cuam tshuam rau lawv txoj kev txav los yog siv zog. Thaum muab tshuaj rau nas rau 10 hnub, Lac-Phe txo cov khoom noj kom tsawg thiab lub cev hnyav (vim poob ntawm lub cev rog) thiab txhim kho cov ntshav qabzib siab.

CNDP2 enzyme deficiency

Cov kws tshawb fawb kuj pom tias ib qho enzyme hu ua CNDP2 koom nrog hauv kev tsim cov Lac-Phe thiab tias cov nas uas tsis muaj cov enzyme no tsis poob ntau npaum li qhov hnyav ntawm kev tawm dag zog raws li lawv tau ua nrog pawg tswj hwm ntawm tib lub tswv yim kev tawm dag zog.

Ua yeeb yam nce

Interestingly, pab pawg ntawm cov kws tshawb fawb kuj tau kuaj pom qhov nce siab hauv cov ntshav plasma Lac-Phe tom qab lub cev ua si hauv racehorses thiab tib neeg. Cov ntaub ntawv los ntawm ib pab neeg ua haujlwm aerobic xws li jogging tau pom tias muaj qhov nce siab tshaj plaws hauv cov qib Lac-Phe, uas tshwm sim tom qab sprinting ua raws li kev tawm tsam kev tawm tsam thiab tom qab ntawd kev cob qhia endurance.

Dr. Shaw tau hais tias "Peb (pab kws tshawb fawb) cov kauj ruam tom ntej no suav nrog kev nrhiav cov ntsiab lus ntxiv txog Lac-Phe kho nws cov teebmeem hauv lub cev, suav nrog lub hlwb," Dr. Shaw tau hais tias "Lub hom phiaj yog kawm los hloov kho txoj hauv kev rau kev kho mob. "
