Tonsefe tikudziwa bwino za kupweteka m'thupi lathu, makamaka minofu yathu, titatha kuchita masewera olimbitsa thupi tsiku lonse kapena titagwira ntchito mwakhama m'nyumba. Anthu ambiri amaganiza kuti chifukwa cha kupweteka kumeneku ndi kuchulukana kwa mankhwala otchedwa 'lactic acid' m'thupi. Koma kodi ndi zoonadi? Lero, tiyeni tiphunzire bwino za lactic acid, yomwe anthu ambiri saimvetsa.
Mwachidule, kodi lactic acid ndi chiyani?
Lactic acid ndi mankhwala omwe thupi lanu limapanga pamene maselo anu akuswa chakudya kuti apeze mphamvu. Nthawi zina amatchedwa lactate. Kawirikawiri imapangidwa ndi maselo a minofu ndi maselo ofiira a magazi, koma kwenikweni imatha kupangidwa ndi minofu iliyonse m'thupi lanu.
Anthu ambiri amadziwa za lactic acid ngati chinthu chomwe chimachitika panthawi yochita masewera olimbitsa thupi. Inde, mukamagwira ntchito molimbika, mukugwira ntchito pabwalo, kapena mukunyamula katundu kwa mnzanu, minofu yanu imapanga lactic acid yambiri. Izi zili choncho chifukwa thupi lanu silingagwiritse ntchito mpweya kuti lipange mphamvu monga momwe limachitira nthawi zonse.
Taganizirani izi, thupi lanu lili ndi njira ziwiri zopangira mphamvu. Choyamba ndi kupanga mphamvu pogwiritsa ntchito mpweya (aerobic). Chinanso ndi kupanga mphamvu mwachangu popanda mpweya (anaerobic). Mukachita zinthu monga kuthamanga kapena kunyamula katundu mwadzidzidzi, thupi lanu silingathe kupereka mpweya mwachangu momwe likufunira. Pamenepo thupi lanu limasinthira ku njira yachiwiri. Zotsatirapo za njira yachiwiriyi ndi lactic acid.
Koma kuwonjezeka kwa kanthawi kochepa kwa lactic acid sikuli koopsa konse . Nthawi zambiri sikubweretsa zizindikiro zilizonse. Chiwindi ndi impso zanu zimasefa lactic acid yochulukirapo iyi kuchokera m'magazi anu ndikuisintha kukhala shuga, yotchedwa glucose, yomwe ingagwiritsidwe ntchito ngati mphamvu.
Kotero lactic acid si chinthu choipa?
Ayi konse! Lactic acid ndi chinthu chofunikira kwambiri m'thupi lathu. Si chinthu chongotayira zinthu zokha. Imagwira ntchito zingapo zofunika.
| Ntchito zazikulu za lactic acid | Zina zonse ndi ... |
|---|---|
| Kupereka mphamvu | Maselo anu akagwiritsidwa ntchito mopitirira muyeso, monga panthawi yochita masewera olimbitsa thupi, lactic acid imathandiza kupereka mphamvu mwachangu zomwe amafunikira. |
| Kuchuluka kwa shuga m'magazi | Asidi wa lactic wopangidwa m'minofu umayenda kudzera m'magazi kupita ku chiwindi ndi impso, komwe umasinthidwa kukhala shuga ndikusungidwa m'thupi kuti ugwiritsidwe ntchito pambuyo pake ngati mphamvu. |
| Kuchita ngati molekyulu yodziwitsa | Lactic acid ili ngati chizindikiro chomwe chimanyamula mauthenga m'thupi lonse. Taganizirani izi ngati kulemba chizindikiro pamsewu ndi mbendera mukakhala kuntchito. Pakakhala kuvulala kapena matenda, lactic acid ndi yomwe imauza maselo a chitetezo chamthupi kuti "abwere kuno" kudzachiritsa dera limenelo. |
Kodi si lactic acid kwenikweni yomwe imayambitsa kupweteka kwa minofu?
Iyi ndi mfundo yolakwika kwambiri pakati pa anthu ambiri. Ayi, lactic acid si yomwe imayambitsa kupweteka kwa minofu komwe kumachitika tsiku limodzi kapena awiri mutatha kuchita masewera olimbitsa thupi.
Kale, ngakhale madokotala ankaganiza kuti lactic acid ndiye imayambitsa ululuwu. Koma kafukufuku watsopano wapeza kuti lactic acid imachotsedwa m'minofu patangopita mphindi zochepa kuchokera pamene munthu akuchita masewera olimbitsa thupi. Choncho siili ndi nthawi yowononga maselo kapena kuyambitsa ululu.
Ululu umenewu umayamba chifukwa cha misozi yaying'ono (microtears) mu ulusi wa minofu yanu mukamachita masewera olimbitsa thupi molimbika. Izi ndi zabwino. Chifukwa pamene thupi likukonza misozi yaying'ono iyi, minofu imakula komanso imakhala yolimba kuposa kale. Komabe, ngati muli ndi ululu waukulu , ukhoza kukhala vuto lotchedwa kupsinjika kwa minofu. Pazochitika zotere, ndikofunikira kupuma ndikupempha upangiri wa dokotala ngati kuli kofunikira.
Lactic acidosis ikhoza kukhala vuto loopsa.
Pali mitundu iwiri ya matenda omwe angayambitse kuwonjezeka kwakanthawi kwa lactic acid panthawi yochita masewera olimbitsa thupi: lactic acidosis.
Lactic acidosis ndi vuto lomwe kuchuluka kwa lactic acid m'magazi kumakhala koopsa kwambiri pamene thupi silingathe kuchotsa bwino lactic acid yomwe limapanga. Imeneyi ndi vuto lalikulu kwambiri, nthawi zina lomwe limakhala pachiwopsezo.
Izi nthawi zambiri zimachitika ngati vuto la matenda ena omwe amabwera chifukwa cha matendawa.
- Kulephera kwa impso
- Kulephera kwa chiwindi kapena cirrhosis
- Kulephera kwa mtima
- Matenda oopsa komanso sepsis
- Matenda ena a khansa
| Zizindikiro zodziwika bwino za lactic acidosis | |
|---|---|
| Kusanza ndi kusanza | Thupi likuyesera kuchotsa asidi wochulukirapo mwachangu momwe lingathere. |
| Kufooka | Kumva ngati munthu alibe moyo, makamaka m'minofu. |
| Kuwawa kwam'mimba | Kupweteka m'mimba kapena kusasangalala. |
Chofunika kwambiri ndichakuti musanyalanyaze zizindikirozi, makamaka ngati muli ndi matenda ena monga matenda a shuga kapena matenda a impso. Izi ndi zadzidzidzi. Muyenera kupita ku Dipatimenti Yoona za Zadzidzidzi (ETU) ya chipatala mwachangu momwe mungathere.
Kodi kuchuluka kwa lactic acid m'magazi kumayesedwa bwanji?
Ngati dokotala wanu akukayikira kuti muli ndi lactic acidosis, adzakuyezani magazi kuti atsimikizire kuti mwapezeka ndi matendawa. Izi zidzayesa kuchuluka kwa lactic acid m'magazi mwanu. Kenako dokotalayo adzasankha chithandizo chomwe chikufunika kutengera zotsatira zake.
Kuphatikiza apo, pali mayeso apadera a othamanga otchedwa 'Lactate Threshold Test'. Izi zimachitika kuti zithandize wothamanga kudziwa malire ake apamwamba a kupirira ndikuchita masewera olimbitsa thupi mosamala. Mayesowa ayenera kuchitika moyang'aniridwa ndi dokotala.
Kodi lactic acid ndi njira yolerera mimba?
Izi ndi zabwino kudziwa. Pa njira zina zolerera, madokotala amalimbikitsa jeli yapadera (jeli ya nyini) yokhala ndi lactic acid, citric acid, ndi potassium bitartrate. Ichi ndi chinthu chomwe chimapakidwa ku nyini musanagonane. Komabe, ichi ndi chinthu chosiyana kwambiri ndi lactic acid yomwe thupi lanu limapanga mwachilengedwe.Kuchuluka kwa lactic acid komwe kumachitika m'thupi sikukhudza mimba.
Uthenga Wopita Nawo Kunyumba
- Lactic acid si chinthu chotayidwa, koma ndi mafuta ndi chizindikiro chomwe chimapatsa mphamvu thupi ndikulithandiza kuchira.
- Kupweteka kwa minofu komwe kumachitika masiku angapo mutatha kuchita masewera olimbitsa thupi sikumachitika chifukwa cha lactic acid, koma chifukwa cha misozi yochepa yomwe imapanga minofu.
- Lactic acidosis ndi matenda oopsa omwe angachitike ndi matenda ena. Siziyenera kusokonezedwa ndi kuchita masewera olimbitsa thupi wamba.
- Ngati muli ndi zizindikiro monga nseru, kusanza, kapena kufooka kwambiri, makamaka ngati muli ndi matenda ena, pitani kuchipatala nthawi yomweyo .
- Njira yabwino yodzitetezera ku kuvulala kwa minofu ndiyo kutenthetsa thupi bwino musanayambe kuchita masewera olimbitsa thupi komanso kuchita masewera olimbitsa thupi nthawi zonse.
