Peb txhua tus paub txog qhov mob hauv peb lub cev, tshwj xeeb tshaj yog peb cov leeg, tom qab ua ib hnub tawm dag zog lossis tom qab ua haujlwm hnyav hauv tsev. Muaj ntau tus neeg xav tias qhov mob no yog vim muaj cov tshuaj hu ua 'lactic acid' sib sau ua ke hauv lub cev. Tab sis puas yog qhov ntawd tiag? Hnub no, cia peb kawm txog lactic acid, uas ntau tus neeg nkag siab yuam kev.
Hauv lwm lo lus, lactic acid yog dab tsi?
Lactic acid yog ib yam tshuaj uas koj lub cev tsim tawm thaum koj cov hlwb zom cov carbohydrates kom tau lub zog. Qee zaum nws hu ua lactate. Feem ntau nws yog tsim los ntawm koj cov leeg nqaij thiab cov qe ntshav liab, tab sis nws tuaj yeem tsim los ntawm txhua yam nqaij hauv koj lub cev.
Feem ntau cov neeg tsuas paub txog lactic acid ua ib yam dab tsi uas tshwm sim thaum lub sijhawm ua si. Yog lawm, thaum koj ua haujlwm hnyav, ua haujlwm hauv vaj, lossis nqa khoom rau ib tug phooj ywg, koj cov leeg nqaij tsim ntau lactic acid. Qhov ntawd yog vim koj lub cev tsis tuaj yeem siv oxygen los tsim lub zog zoo li nws ib txwm ua.
Xav txog nws, koj lub cev muaj ob txoj hauv kev los tsim lub zog. Ib qho yog tsim lub zog siv oxygen (aerobic). Qhov thib ob yog tsim lub zog sai sai yam tsis muaj oxygen (anaerobic). Thaum koj ua ib yam dab tsi zoo li khiav lossis tsa ib qho hnyav, koj lub cev tsis tuaj yeem muab oxygen sai li nws xav tau. Thaum ntawd koj lub cev hloov mus rau txoj kev thib ob. Ib qho kev phiv ntawm txoj kev thib ob no yog lactic acid.
Tiamsis qhov kev nce ntxiv ntawm cov lactic acid hauv lub sijhawm luv luv no tsis txaus ntshai kiag li . Feem ntau nws tsis ua rau muaj tsos mob dab tsi. Koj lub siab thiab lub raum lim cov lactic acid ntau dhau no ntawm koj cov ntshav thiab tig nws rov qab mus ua qab zib, hu ua glucose, uas tuaj yeem siv ua lub zog.
Yog li ntawd, lactic acid tsis yog qhov phem?
Tsis yog li ntawd! Lactic acid yog ib yam tseem ceeb heev rau peb lub cev. Nws tsis yog tsuas yog cov khoom pov tseg xwb. Nws ua ntau yam haujlwm tseem ceeb.
| Cov haujlwm tseem ceeb ntawm lactic acid | Tus so tsuas yog ... |
|---|---|
| Muab zog | Thaum koj cov hlwb ua haujlwm ntau dhau, xws li thaum lub sijhawm tawm dag zog, cov kua qaub lactic pab muab lub zog sai uas lawv xav tau. |
| Kev tsim cov gluconeogenesis | Cov kua qaub lactic uas tsim tawm hauv cov leeg nqaij mus los ntawm cov ntshav mus rau lub siab thiab lub raum, qhov chaw uas nws hloov rov qab mus ua qabzib thiab khaws cia rau hauv lub cev rau kev siv ua lub zog tom qab. |
| Ua haujlwm ua ib lub molecule signaling | Lactic acid zoo li lub cim uas nqa cov lus thoob plaws lub cev. Xav txog nws zoo li cim txoj kev nrog cov chij thaum koj ua haujlwm. Thaum muaj kev raug mob lossis kev kis kab mob, lactic acid yog qhov uas qhia cov hlwb tiv thaiv kab mob kom "tuaj ntawm no" los kho qhov chaw ntawd. |
Yog li, puas yog lactic acid ua rau mob leeg tiag?
Qhov no yog qhov kev nkag siab yuam kev loj tshaj plaws ntawm ntau tus neeg. Tsis yog, lactic acid tsis yog qhov ua rau mob nqaij uas tshwm sim ib lossis ob hnub tom qab kev tawm dag zog.
Yav dhau los, txawm tias cov kws kho mob xav tias lactic acid yog qhov ua rau mob no. Tab sis kev tshawb fawb tshiab tau pom tias lactic acid raug tshem tawm ntawm cov leeg nqaij hauv ob peb feeb ntawm kev tawm dag zog. Yog li nws tsis muaj sijhawm los ua puas rau cov hlwb lossis ua rau mob.
Qhov mob no yog tshwm sim los ntawm cov kua muag me me (microtears) hauv cov leeg nqaij thaum koj tawm dag zog hnyav. Qhov no yog ib qho zoo. Vim tias thaum lub cev kho cov kua muag me me no, cov leeg nqaij loj hlob thiab muaj zog dua li yav dhau los. Txawm li cas los xij, yog tias koj muaj mob hnyav , nws yuav yog ib qho mob hu ua mob nqaij. Hauv cov xwm txheej zoo li no, nws yog ib qho tseem ceeb uas yuav tsum so thiab nrhiav kev kho mob yog tias tsim nyog.
Lactic acidosis tuaj yeem yog ib qho mob txaus ntshai.
Muaj ob hom mob uas ua rau cov lactic acid nce ntxiv ib ntus thaum lub sijhawm ua si: lactic acidosis.
Lactic acidosis yog ib qho mob uas cov lactic acid hauv cov ntshav nce siab heev thaum lub cev tsis tuaj yeem tshem tawm cov lactic acid ntau dhau uas nws tsim tawm. Qhov no yog ib qho mob hnyav heev, qee zaum ua rau tuag taus.
Qhov no feem ntau tshwm sim ua ib qho teeb meem ntawm lwm yam mob uas twb muaj lawm.
- Kev ua haujlwm tsis zoo ntawm lub raum
- Kev ua haujlwm tsis zoo ntawm daim siab lossis cirrhosis
- Lub plawv tsis ua haujlwm
- Kab mob hnyav thiab sepsis
- Qee yam mob qog noj ntshav
| Cov tsos mob ntawm lactic acidosis feem ntau | |
|---|---|
| Xeev siab thiab ntuav | Lub cev tab tom sim tshem tawm cov kua qaub ntau dhau sai li sai tau. |
| Tsis muaj zog | Kev xav tias tsis muaj sia nyob, tshwj xeeb tshaj yog nyob rau hauv cov leeg nqaij. |
| Mob plab | Mob plab los yog tsis xis nyob. |
Qhov tseem ceeb tshaj plaws yog koj yuav tsum tsis txhob tsis quav ntsej cov tsos mob no, tshwj xeeb tshaj yog tias koj muaj lwm yam mob xws li ntshav qab zib lossis kab mob raum. Qhov no yog xwm txheej ceev. Koj yuav tsum mus rau chav kho mob ceev (ETU) ntawm tsev kho mob sai li sai tau.
Yuav ntsuas cov lactic acid li cas?
Yog koj tus kws kho mob xav tias koj muaj mob lactic acidosis, lawv yuav kuaj ntshav kom paub tseeb tias koj tau kuaj mob. Qhov no yuav ntsuas qhov ntau ntawm cov lactic acid hauv koj cov ntshav.

Tsis tas li ntawd xwb, muaj ib qho kev xeem tshwj xeeb rau cov neeg ncaws pob hu ua 'Lactate Threshold Test'. Qhov no yog ua los pab tus neeg ncaws pob paub lawv qhov kev ua siab ntev tshaj plaws thiab cob qhia kom muaj kev nyab xeeb. Qhov kev xeem no yuav tsum tau ua nyob rau hauv kev saib xyuas ntawm kws kho mob.
Puas yog lactic acid yog ib txoj kev tiv thaiv kev yug menyuam?
Qhov no kuj yog ib qho zoo uas yuav tsum paub. Rau qee txoj kev tswj kev xeeb tub, cov kws kho mob pom zoo kom siv cov tshuaj gel tshwj xeeb (vaginal gel) uas muaj lactic acid, citric acid, thiab potassium bitartrate. Qhov no yog ib yam dab tsi uas siv rau ntawm qhov chaw mos ua ntej sib deev. Txawm li cas los xij, qhov no yog ib yam dab tsi txawv kiag li ntawm cov lactic acid uas koj lub cev tsim tawm ntuj.Cov theem ib txwm ntawm cov lactic acid uas tsim tawm hauv lub cev tsis muaj feem cuam tshuam rau kev xeeb tub.
Cov Lus Qhia Txog Kev Coj Mus Tsev
- Lactic acid tsis yog cov khoom pov tseg, tab sis yog roj thiab lub cim uas muab zog rau lub cev, pab nws kho, thiab yog qhov ua ntej rau kev tawm dag zog.
- Qhov mob nqaij uas tshwm sim ob peb hnub tom qab kev tawm dag zog tsis yog los ntawm lactic acid, tab sis los ntawm microtears uas tsim nyob rau hauv cov leeg.
- Lactic acidosis yog ib qho mob hnyav uas tuaj yeem tshwm sim nrog lwm yam mob. Nws yuav tsum tsis txhob yuam kev nrog kev tawm dag zog ib txwm muaj.
