Waba yini umphumela wokukhathala kwemisipha ekhonweni lakho - umhlahlandlela wokugcina

Ukukhathala kwemisipha kukuthinta kanjani ukusebenza?

Umsebenzi ojulile weimisiphakubangela ukwehla kwe-ukusebenza, waziwa ngoukukhathala… '(Allen & Westerblad, 2001). 'Ukwenza umsebenzi wezimoto isikhathi eside kudala imotoukukhathala, ngokuvamile okuchazwa njengokuwohloka kwekhono lomuntu lokusebenzisa amandla.



Lo mbhalo uhlola izifundo zokukhathala kwemisipha ngesikhathi esisodwa sokuqeqeshwa. Njengoba uzobona, ayikho inkambo eyodwa yokukhathala kwemisipha. Futhi, imbangela yokukhathala izocaciselwa umcimbi.

Ngamanye amagama, yini enomthelela ekukhathaleni uma uku? Ukuphindaphindwa komshini wokushicilela ebhentshini kuhluke kakhulu emlandweni wokukhathala osekugcineni kwemarathon. Okokuqala, ake sichaze ukuthi kusho ukuthini ukukhathala kwemisipha. Ukukhathala kwemisipha kuchazwa njengokwehluleka ukugcina amandla okusebenza noma ukusebenza okunikeziwe, okuholela ekwehliseni umsebenzi noma ukusebenza.

Nasi isibonelo sencwadi yokuqala ukukhathala kwemisipha. Usezigabeni zokuqala zokuqeqeshwa. Ukukhishwa kwamandla noma ukukhiqizwa kugcinwa kahle.Ukukhiqizwa kwamandla kuyehla, ngaleyo ndlela kufezekise incazelo yethu yokukhathala.



Ama-Physiologists abelokhu efunda izindlela zokukhathala kwemisipha iminyaka. Isihloko siyinkimbinkimbi ngokwedlulele futhi, njengoba sekushiwo, i Ukusetshenziswa kuyehluka kuya ngohlobo lokuvivinya umzimba. Zonke izinyathelo phakathi kwesinqumo ebuchosheni sokuhambisa imisipha kanye nokuncipha kokugcina kwemisipha yamathambo kuyizindawo ezingaba khona zokukhathala.

Ngokuvamile, noma kunjalo, izimbangela zokukhathala zisezindaweni ezisemaphethelweni, kuqala ngokuxhuma kwemisipha ye-neural nangaphezulu. Ngakho-ke ngizogxila kuphela kulezi zingxenye. Njengesikhumbuzo, uhlobo lwemicu yemisipha eqoqiwe idlala indima enkulu ekubangeleni ukukhathala.

Thayipha i-2 X-fibers ebuthwa ngesikhathi esifushane. Amathayi okuqeqesha amafushane, aqine ngokushesha. Ngenkathi imicu yohlobo 1, esetshenziswa phakathi nesikhathi eside, ukuqeqeshwa ngamandla aphansi, ikhathala kancane uma nje kukhona uphethiloli owanele wokukhiqiza i-ATP.



Okokuqala, ake sihlole izimbangela ezivame kakhulu zokukhathala lapho wenza umsebenzi wesikhashana, wokuqina okukhulu. Isibonelo, uma ucindezela isisindo esisindayo ebhentshini, ungahle ukwazi ukwenza ama-reps amahlanu, kepha awukwazi nje ukusunduza owesithupha uphume kumayadi angama-200, ngeke ukwazi ukugcina ijubane lakho phakathi kwama-20 wokugcina amagceke. Imvamisa imbangela yokukhathala ukukhathala noma ukunqwabelana kwezinto ezingaphansi noma ama-metabolites.

Ngenkathi izinto eziningi zingaba nomthelela ekuqaleni kokukhathala, ngizoxoxa ngezimbangela ezintathu ezivame kakhulu zokukhathala kwemisipha ngesikhathi sokuzivocavoca esifushane, sokuqina okukhulu. Lokhu kufaka ukwehla kwazo zombili i-ATP kanye nezitolo ze-creatine phosphate ezicutshini. Kanye nokuqoqwa kwama-hydrogen ions noma ukwanda kwe-acid acid.

Okokuqala, ukuncipha kwe-ATP ngenxa yokungafani phakathi kokusetshenziswa kwe-ATP nokukhiqiza kuholela ekukhathaleni. Njengesikhumbuzo, i-ATP iyadingeka ekuhambeni ngebhayisikili kuwo wonke amabhuloho nasekuthuthukiseni ukungezwani. Uma i-ATP isetshenziswa ngokushesha okukhulu kunalokho engenziwa, amazinga azokwehla ngaphansi kwamazinga okuphumula, lowo muntu kuzodingeka anciphise ukuqina kokuzivocavoca umzimba, okuzokwehlisa izinga lokusetshenziswa kwe-ATP ukuze umkhiqizo we-ATP uhambe ijubane, noma umuntu Isidingo sokuzivocavoca Okwesibili, izitolo ze-creatine phosphate zisetshenziswa ngokushesha ngesikhathi esifushane, sokuqeqeshwa ngamandla.



Njengoba i-creatine phosphate ingumthombo oyinhloko wamandla emisipha yokukhiqiza i-ATP, ukuncipha kwayo kuthinta ikhono lokugcina amazinga e-ATP. Lapha i-ATP ne-creatine phosphate ikhonjiswa kwimisipha ekuphenduleni ekusebenzeni okuphezulu. Qaphela ukuthi amazinga e-creatine phosphate, afushaniselwe i-PC ye-phosphocreatine, ehla ngokushesha okukhulu ngale ndlela.

Lapho amazinga ephansi kakhulu, kuthinta kabi amandla ethu okukhiqiza futhi ngaleyo ndlela kugcinwe amazinga e-ATP. Imisipha yehla kakhulu, okuholela ekukhatheni noma ekukhathaleni. Isizathu sesithathu esivamile sokukhathala kwemisipha ngesikhathi esifushane, ukuvivinya umzimba ngamandla ukwanda kwe-muscle acid noma ukwakhiwa kwama-ion e-hydrogen.

isihlalo esihamba ngebhayisikili

Le metosis acidosis ingaba nomthelela ekukhathaleni ngezindlela eziningi. Ukugxila kwe-hydrogen ions kungadlala indima ye-calcium ekwakheni amabhuloho awele futhi ngaleyo ndlela kwakheke imisipha. Njengoba uzokhumbula, i-anaerobic glycolysis ingumthombo omkhulu wokukhiqizwa kwe-ATP ngesikhathi esifushane, ukuqeqeshwa okunamandla ezitolo ze-creatine phosphate, kuhlangene nokwehliswa kokukhiqizwa kwe-ATP ngenxa ye-anaerobic glycolysis, kuholela ekuqaleni kokukhathala kwemisipha.

Njengoba kukhulunyiwe endatshaneni yezidakamizwa ezithuthukisa ukusebenza, lo ngumqondo lapho ukulayishwa kwe-buffer kungahle kuholele ekuthuthukeni kokusebenza kwemisipha ngesikhathi sokuvivinya ngamandla okukhulu. Ukukhulisa amandla okubhaxabula ngaphambi kokuzibandakanya kule misebenzi enamandla kuvumela ukungasebenzi kahle noma ukubuyisa imiphumela engemihle ehambisana ne-metabolic acidosis. Kuboniswe lapha yisibonelo esibonisa ukuthi abesifazane abaqeqeshiwe babelashelwa ukuzilolonga okuphelele ngaphambi kokuthatha i-sodium bicarbonate futhi bakwazi ukusebenza ngamandla aphakeme kakhulu nokuqina imizuzwana engama-60.

Uma kuqhathaniswa nokuthi benze isivivinyo esifanayo ngqo nge-placebo noma bengekho isengezo. Lesi ngesinye sezifundo eziningi eziphakamisa ukuthi i-metabolic acidosis iyisici esinomthelela ekukhathaleni ngesikhathi sokuvivinya umzimba ngamandla amancane - okuyizimbangela ezintathu ezivame kakhulu zokukhathala phakathi nokuvivinya umzimba okuhlala isikhathi eside. Njengoba ngishilo ekuqaleni, ukuncipha kwe-carbohydrate kuyimbangela ejwayelekile yokukhathala phakathi nalolu hlobo lokuzivocavoca.

Futhi, ngokuhamba kwesikhathi, ukwehla kwamazinga we-calcium yemisipha kungaba nomthelela ekukhathaleni. Ekugcineni, ukwakheka kokushisa noma ukwanda kokushisa komzimba kanye nemisipha kuyinto engaba namandla ekukhuleni kokukhathala. Ukubamba iqhaza emicimbini yebanga efana ne-marathon kungukuqina okuncane noma okulingene kokuqeqeshwa okungabekezelelwa noma kugcinwe isikhathi eside.

Ukuwohloka kwemisipha ye-glycogen kuvame ukuqondana nokukhathala okungagcwaliseki njengoba umthombo oyinhloko we-ATP wokukhiqiza ungasekho. Ngenxa yalokhu, inqubo yokulayisha kwe-carbohydrate, eyaziwa ukwandisa izitolo zemisipha ye-glycogen ngaphambi komncintiswano, ingathuthukisa ukusebenza. Lapho i-muscle glycogen isetshenzisiwe, lowo muntu unezinketho ezimbili.

Nciphisa ukuqina koqeqesho futhi ngaleyo ndlela ijubane lokusetshenziswa kwe-ATP noma ukuphela koqeqesho. Zombili lezi zimo zifanelana nencazelo yethu yokukhathala kwemisipha. Ngaphezu kwalokho, ukuncipha kwesibindi glycogen ekugcineni kuholela ekwehleni okuncane kwamazinga kashukela egazini noma i-hypoglycemia.

Njengoba imisipha nobuchopho kuncike kushukela wegazi ukuthola uphethiloli, ikhono lokuqhubeka nokuzivocavoca alilondolozi uma kufinyelelwe i-hypoglycemia. Ngalesi sizathu, futhi, ukusetshenziswa kweziphuzo ezihlanjululwe ze-carbohydrate ngesikhathi semicimbi yebanga kungaholela ekwandeni kokusebenza. Ngamahora wokuzivocavoca, i-cytoplasmic reticulum emangqamuzaneni emisipha ingavuselelwa kaninginingi ukukhipha i-calcium ukuze yakhe amabhuloho anqamulelayo, futhi ngokuhamba kwesikhathi, enye yekhalsiyamu ekhishwe ingavuza uketshezi olungaphandle kwamangqamuzana kanye / noma ingamuncwa yi-mitochondria.

Lokhu kungasho ukuthi i-calcium engaphansi iyatholakala ngokusikwa kwemisipha ngakho-ke amandla noma ukuphuma kwamandla kukhubazekile futhi ukushisa kwemisipha kungaholela ekukhathaleni. Ngokuzivocavoca umzimba isikhathi eside, la mazinga okushisa angafinyelela ku-42 degrees Celsius noma ku-108 degrees Fahrenheit. Lokhu kubangela ukuthi amaphesenti amakhulu egazi lakho aqondiswe kabusha esikhunjeni ukuze kusetshenziswe i-thermoregulation.

Lokhu kusho ukuthi igazi elincane ligeleza liye emisipheni yezithako ezisebenzayo. Ngaphezu kwalokho, ukungangenisi amanzi ngokwanele kuholela ekwehleni kwevolumu ye-plasma, eyehlisa ukukhishwa kwenhliziyo yakho nokunikezwa kwegazi emisipheni. Ngokufingqa, ukukhathala kwemisipha kuchazwa njengokuhluleka ukugcina izinga elithile lokuqina kokuvivinya umzimba noma ukuphuma kwamandla kuholela ekwehleni komsebenzi noma ekukhiqizeni.

Umbono ovame kakhulu wokukhathala ngesikhathi sokuzivocavoca usemisipheni uqobo. Izimbangela zokukhathala ziqondene nomsebenzi futhi zingabangelwa ukukhathala noma ukunqwabelana kokuguqukayo okubalulekile. Ekugcineni, izimbangela zokukhathala emicimbini emaphakathi njengokugijima okungu-10k kungenzeka kube yizici ezikhulunywe ngazo zombili zesikhashana, ukuqeqeshwa ngamandla kanye nesikhathi eside, ukuqeqeshwa ngamandla aphansi.
