Sonke siqhelene nokuziva sibuhlungu emizimbeni yethu, ingakumbi izihlunu zethu, emva kosuku olunzima lokuzilolonga okanye emva kokusebenza nzima endlwini. Abantu abaninzi bacinga ukuba unobangela wobu buhlungu kukuqokelelana kwekhemikhali ebizwa ngokuba yi-'lactic acid' emzimbeni. Kodwa ngaba kunjalo ngokwenene? Namhlanje, makhe sifunde ngqo nge-lactic acid, abantu abaninzi abangayiqondi kakuhle.
Ngamafutshane, yintoni i-lactic acid?
I-lactic acid yikhemikhali eveliswa ngumzimba wakho xa iiseli zakho ziqhekeza iicarbohydrate ukuze zenze amandla. Ngamanye amaxesha ibizwa ngokuba yi-lactate. Idla ngokuveliswa ziiseli zakho zemisipha kunye neeseli ezibomvu zegazi, kodwa inokuveliswa nayiyiphi na izicubu emzimbeni wakho.
Uninzi lwabantu luyazi kuphela nge-lactic acid njengento eyenzekayo ngexesha lokuzilolonga. Ewe, xa usebenza nzima, usebenza ebaleni, okanye uphakamisela umhlobo wakho umthwalo, izihlunu zakho zivelisa i-lactic acid eninzi. Kungenxa yokuba umzimba wakho awukwazi ukusebenzisa ioksijini ukuvelisa amandla njengoko ubuya kwenza ngokuqhelekileyo.
Cinga ngayo, umzimba wakho uneendlela ezimbini zokuvelisa amandla. Enye kukuvelisa amandla usebenzisa ioksijini (i-aerobic). Enye kukuvelisa amandla ngokukhawuleza ngaphandle kweoksijini (i-anaerobic). Xa ngequbuliso wenza into efana nokubaleka okanye ukuphakamisa ubunzima, umzimba wakho awukwazi ukubonelela ngeoksijini ngokukhawuleza njengoko uyidingayo. Kulapho ke umzimba wakho utshintshela kwindlela yesibini. Isiphumo esibi sale ndlela yesibini yi-lactic acid.
Kodwa oku kunyuka kwexesha elifutshane kwamanqanaba e-lactic acid akuyongozi konke konke . Ngokuqhelekileyo akubonisi zimpawu. Isibindi sakho kunye nezintso zihluza le lactic acid igqithisileyo egazini lakho zize ziyiguqule ibe yiswekile, ebizwa ngokuba yiglucose, enokusetyenziswa njengamandla.
Ngoko ke i-lactic acid ayisiyonto imbi?
Akunjalo konke konke! I-lactic acid yinto ebaluleke kakhulu emzimbeni wethu. Ayisiyonto nje elahlwayo. Yenza imisebenzi emininzi ebalulekileyo.
| Imisebenzi ephambili ye-lactic acid | Okunye nje... |
|---|---|
| Ukubonelela ngamandla | Xa iiseli zakho zisebenza kakhulu, njengaxa uzilolonga, i-lactic acid inceda ekunikeni amandla akhawulezileyo afunekayo. |
| I-Gluconeogenesis | I-lactic acid eveliswa kwimisipha ihamba ngegazi iye esibindini nasezintsoni, apho iguqulwa ibe yiglucose ize igcinwe emzimbeni ukuze isetyenziswe kamva njengamandla. |
| Isebenza njengemolekyuli yokubonisa | I-lactic acid ifana nomqondiso othwala imiyalezo emzimbeni wonke. Cinga ngayo njengokuphawula indlela ngeeflegi xa usebenza. Xa kukho ukwenzakala okanye usulelo, i-lactic acid yiyo enika umqondiso kwiiseli zomzimba ukuba "zize apha" ukuzophilisa loo ndawo. |
Ngoko ke, asikuko na ukuba yi-lactic acid ebangela ukuqaqamba kwemisipha?
Le yeyona ngcamango iphosakeleyo kubantu abaninzi. Hayi, i-lactic acid ayisiyonto ibangela ukuqaqamba kwemisipha okwenzeka emva kosuku okanye ezimbini emva kokuzilolonga.
Ngaphambili, noogqirha babecinga ukuba i-lactic acid yiyo ebangela le ntlungu. Kodwa uphando olutsha lufumanise ukuba i-lactic acid isuswa kwimisipha kwimizuzu embalwa yokuzilolonga. Ngoko ke ayinalo ixesha lokonakalisa iiseli okanye ukubangela intlungu.
Le ntlungu ibangelwa kukukrazuka okuncinci (ii-microtears) kwimicu yemisipha yakho xa uzilolonga nzima. Oku kulungile. Kuba njengoko umzimba ulungisa ezi krazuka zincinci, izihlunu ziyakhula zibe nkulu kwaye zomelele kunangaphambili. Nangona kunjalo, ukuba unentlungu enzima , isenokuba yimeko ebizwa ngokuba kukukrazuka kwemisipha. Kwiimeko ezinjalo, kubalulekile ukuphumla kwaye ufumane ingcebiso kagqirha ukuba kuyimfuneko.
I-lactic acidosis inokuba yimeko eyingozi.
Kukho iintlobo ezimbini zeemeko ezinokubangela ukunyuka okwethutyana kwamanqanaba e-lactic acid ngexesha lokuzilolonga: i-lactic acidosis.
I-lactic acidosis yimeko apho inqanaba le-lactic acid egazini liba phezulu ngendlela eyingozi xa umzimba ungakwazi ukususa ngokufanelekileyo i-lactic acid egqithisileyo oyivelisayo. Le yimeko embi kakhulu, ngamanye amaxesha esongela ubomi.
Oku kudla ngokuba yingxaki yesinye isifo esingabonakaliyo.
- Ukungasebenzi kakuhle kwezintso
- Ukungasebenzi kakuhle kwesibindi okanye isifo sesibindi
- Ukumelwa yintliziyo
- Usulelo olunzima kunye ne-sepsis
- Ezinye izifo zomhlaza
| Iimpawu eziqhelekileyo ze-lactic acidosis | |
|---|---|
| Isicaphucaphu nokuhlanza | Umzimba uzama ukukhupha i-asidi egqithisileyo ngokukhawuleza. |
| Ubuthathaka | Ukuziva ungenabomi, ingakumbi kwimisipha. |
| Isisu esibuhlungu | Intlungu yesisu okanye ukungakhululeki. |
Eyona nto ibalulekileyo kukuba ungaze uzityeshele ezi mpawu, ingakumbi ukuba unezinye izifo ezifana nesifo seswekile okanye isifo sezintso. Le yingxamiseko yezonyango. Kufuneka uye kwiSebe lezeMpilo eziNgxamisekileyo (ETU) lesibhedlele ngokukhawuleza.
Amanqanaba e-lactic acid alinganiswa njani?
Ukuba ugqirha wakho ukrokrela ukuba une-lactic acidosis, uza kwenza uvavanyo lwegazi ukuqinisekisa ukuxilongwa. Oku kuya kulinganisa ubungakanani be-lactic acid egazini lakho. Ugqirha uya kugqiba ukuba loluphi unyango olufunekayo ngokusekelwe kwiziphumo.
Ukongeza, kukho uvavanyo olukhethekileyo lwabadlali olubizwa ngokuba yi-'Lactate Threshold Test'. Oku kwenzelwa ukunceda umdlali azi umda wakhe wokunyamezela aze azilolonge ngokukhuselekileyo. Olu vavanyo kufuneka lwenziwe phantsi kweliso likagqirha.
Ngaba i-lactic acid yindlela yokulawula ukukhulelwa?
Oku kulungile ukwazi. Ezinye iindlela zokulawula ukuzala zicebisa ijeli ekhethekileyo yesini equlethe i-lactic acid, i-citric acid, kunye ne-potassium bitartrate. Le yinto esetyenziswa kwisini ngaphambi kokwabelana ngesondo. Nangona kunjalo, oku kwahlukile ngokupheleleyo kwi-lactic acid eveliswa ngumzimba wakho ngokwendalo.Amanqanaba aqhelekileyo e-lactic acid eveliswa emzimbeni awayichaphazeli intshukumo yokukhulelwa.
Umyalezo Wokuya Ekhaya
- I-lactic acid ayisiyonto ilahlwayo, kodwa iluphawu olunika umzimba amandla kwaye luwuncede uphilise.
- Ukuqaqamba kwemisipha okwenzeka emva kweentsuku ezimbalwa emva kokuzilolonga akubangelwa yi-lactic acid, kodwa kukukrazula okuncinci okwenziwa kwimisipha.
- I-lactic acidosis yimeko embi kakhulu yezonyango enokwenzeka nakwezinye iimeko zezempilo. Akufanele idideke nokuzilolonga okuqhelekileyo.
- Ukuba uneempawu ezifana nokucaphuka, ukuhlanza, okanye ubuthathaka obukhulu, ingakumbi ukuba unezinye izifo, bona ugqirha ngoko nangoko .
- Eyona ndlela ilungileyo yokuzikhusela ekulimaleni kwemisipha kukuzifudumeza kakuhle ngaphambi kokuba wenze naluphi na umthambo kwaye uzenze rhoqo umthambo wokuzolula .
