1. Sarcopenia
Sarcopenia yog ib qho mob tshwm sim los ntawm qhov tsis tu ncua ntawm cov leeg pob txha, lub zog thiab kev ua haujlwm poob qis, nrog rau kev loj hlob ntawm lub hnub nyoog, cov leeg pob txha ntawm 30 xyoo ntawm hnub nyoog qis dua 0.1 feem pua ~ 0.5 feem pua. ib xyoos, nce nrawm dua tom qab hnub nyoog 65 xyoos, tib lub sijhawm nrog kev txo qis ntawm cov leeg nqaij, ua rau cov neeg laus sawv ntsug nyuaj, taug kev qeeb, yooj yim poob thiab tawg, sarcopenia tuaj yeem cuam tshuam rau lub cev ua haujlwm, tuaj yeem ua rau lub plawv. thiab mob ntsws tsis ua hauj lwm thiab txawm tuag. Cov kev tshawb fawb tau pom tias ceg saw amino acids muaj kev txhawb nqa ncaj qha rau kev loj hlob thiab kho cov leeg pob txha. Ntxiv cov ceg saw amino acids tuaj yeem tiv thaiv lossis ncua qhov tshwm sim ntawm sarcopenia. Kev noj zaub mov ntxiv ntawm ceg saw amino acids kuj tau dhau los ua qhov kev cuam tshuam tseem ceeb rau sarcopenia.
2. Paub txog branched saw amino acid
Branched chain amino acid (BCAA) yog lub npe dav dav ntawm peb yam tseem ceeb amino acids, leucine, valine thiab isoleucine. Ceg saw amino acids tiv thaiv qaug zog, muab lub zog rau lub cev thaum muaj xwm txheej ceev, thiab tseem ceeb tshaj, txhawb cov leeg nqaij synthesis.
BCAA tau koom ncaj qha rau hauv cov txheej txheem metabolic ntawm ketogenesis thiab glycogenesis hauv cov leeg, kom ntau hom nqaij fibers hauv cov leeg pob txha tuaj yeem tau txais lub zog txaus. Ceg saw amino acids ua lub luag haujlwm tsis hloov pauv hauv kev tiv thaiv sarcopenia vim lawv cov oxidation ntau dua li lwm hom amino acids thiab lawv cov yam ntxwv hauv cov leeg nqaij metabolism. Branched saw amino acids feem ntau pom muaj nyob rau hauv cov khoom noj uas muaj cov ntsiab lus protein ntau, xws li nqaij protein. Yog li, kev noj zaub mov kom tsim nyog yog qhov tseem ceeb ntawm cov saw saw amino acids. Txawm li cas los xij, rau cov neeg laus, cov metabolism qeeb thiab kev noj zaub mov tsis txaus yuav ua rau qhov tsis txaus ntawm cov amino acids hauv lub cev, yog li nws yog qhov tsim nyog los ntxiv cov ceg amino acids nrog kev pab txawv teb chaws.
3. Poov xab protein nplua nuj nyob rau hauv branched saw amino acids
Cov poov xab protein yog ib yam zoo ntawm ntuj ua tiav protein ntau nplua nuj nyob rau hauv branched saw amino acids. Vim nws qhov zoo ntawm tus nqi raw khoom, ntsuab, muaj kev nyab xeeb thiab ruaj khov, cov poov xab protein yog siv dav hauv cov khoom noj khoom haus thiab cov khoom noj khoom haus, thiab nws yog cov khoom noj khoom haus zoo. Cov poov xab protein tau dhau los ua ib qho zoo ntxiv rau cov saw saw amino acids uas yog lub zog tshiab rau kev cuam tshuam hauv kev txo qis sarcopenia hauv cov neeg laus.
