I-Phosphocreatine Yinto Yemvelo Ethuthukisa Ukusebenza Kwezemidlalo
I-Phosphocreatine, eyaziwa nangokuthi i- creatine phosphate, ingumthombo wamandla we-muscle contraction ngokwemvelo okhona emathanjeni emisipha emisipha yabantu kanye namanye ama-vertebrate. Yenza amandla okubonakalisa amandla okuqhuma emisipha, engapheli imizuzwana engama-8 kuya kwangu-12. I-organic component ye-creatine ne-phosphoric acid ne-formulation molecular of C4H10N3O5P
I-Phosphocreatine Energy System
Imisipha isebenzisa isimiso samandla e-phosphocreatine, esaziwa nangokuthi uhlelo lwe-anaerobic alactic, phakathi nemizuzwana yokuqala yokuqala engu-10 ye-muscle contraction. I-anaerobic ngoba ayidingi oksijini ukuze isebenze futhi i-alactic ngoba ayikhiqizi i-lactic acid.
Isistimu yamandla eyenza ukukhishwa kwemisipha isebenzisa i- adenosine triphosphate (ATP). I-ATP ikhiqizwa kusuka ku-glucose ngokusebenzisa indlela ye-glycolytic. Kodwa i-ATP encane igcinwa emisipha futhi umzimba uyisebenzisela emashumini ambalwa okuqala wokuqhaqhazeka kwemisipha. Kudingeka ukuthi igcwaliswe besebenzisa i-phosphocreatine ukuguqula i-adenosine diphosphate (ADP) ibe yi-ATP ku-mitochondria yamaseli emathisini omzimba.
Ukuze wenze i-ATP, i-phosphocreatine idlulisela i-molecule ye-phosphate ku-ADP. I-ATP esanda kusungulwa manje iyatholakala ukuze isetshenziselwe ukukhishwa kwemisipha. Ingxenye esalayo ye-phosphocreatine i-creine, eyenziwa yisibindi ibe yi-creatinine futhi isuswa ngezinso kanye nomchamo.
Umzimba awubuyiseli kabusha lo mhlaba ube yi-phosphocreatine.
Umjikelezo wePhosphocreatine
Ukukhathala kwemisipha kubonakala ekupheleni komjikelezo we-phosphocreatine. Ngemuva kwemizuzwana engu-10 ye-muscle contraction, imisipha iyakwazi ukusebenzisa i-anaerobic glycolysis ne-aerobic glycolysis izindlela zokunikeza amandla. I-Phosphocreatine ivuselelwa yisibindi, ama-pancreas nezinso.
Imisipha ye-skeletal fast-twitch igcina ngaphezulu i-phosphocreatine ukuze itholakale ngezikhathi ezincane ze-muscle contraction okukhulu. Izisipha ze-squid-slow-twitch kanye nesitolo senhliziyo kancane. Ngokweminyaka yobudala, abantu banesitolo esiphansi se-phosphocreatine emisipha yabo.
Indlela Amathimba Abagijimi Asebenzisa Ngayo Ukudala
Ngezemidlalo nokuzivocavoca okudinga ukuqhuma komfutho we-muscle, kunesithakazelo esikhulu ekukhuliseni i-phosphocreatine emisipha ukuze kukhuliswe ukusebenza. Uma une-phosphocreatine engaphezulu emisipha, uyakwazi ukukhuthazelela isikhathi eside kakhulu sokuqina kwe-muscle ngaphambi kokuba umsizi uphelelwe amandla futhi ulahlekelwe amandla. Ukuphakamisa isisindo, sprinting, basketball, ibhola, i-hockey yeqhwa, ukuhamba ngebhayisikili, imidlalo ye-tennis nemidlalo yasensimini ingazuza kusigaba eside se-phosphocreatine. Landelela ama-sprinters angaphezu kwamamitha angu-100 asebenzisa kakhulu uhlelo lwe-phosphocreatine / ATP yokukhiqizwa kwamandla.
I-Creatine Supplementation Yokuthuthukisa i-Phosphocreatine
Ukuxhaswa kokudalwa kwedalwa kungadala ukuhlushwa kwe-creatine ngokuphelele emisipha. Ukudala okwenzeka ngokwemvelo emzimbeni obomvu kungumthombo owodwa, nakuba ungagxili ngokwanele ukukhulisa amazinga e-phosphocreatine emisipha engaphezu kwendabuko.
Ukuphakamisa amazinga e-phosphocreatine, ukwesekwa nge-creatine kusetshenziswa.
Ezinye izakhi zingakhuphula izinga lokudalwa kwemisipha, ikakhulukazi ama-carbohydrate afana ne-glucose nama-ushukela alula. Ngenxa yalesi sizathu, izidlo ezincane ze-carb zingase zingabi yisona esihle kunazo zonke kubadlali abafuna ukwandisa amandla abo okuxhaphaza. Ukuzivocavoca okunamandla nakho kwandisa ukutholakala kwemisipha ye-creativeine creatine.
