I-IGF-1 yi-Ukuvinjelwa Ukusebenza-Ukuthuthukisa Imithi
I-IGF-1 (i-insulin-like growth factor 1) i-polypeptide protein hormone eyenzeka ngokwemvelo, efana ne-insulini, ekhishwa ngokuyinhloko esibindi. I-IGF-1 idlala indima ebalulekile ekushukumiseni ukukhula ngesikhathi seyingane futhi kusiza ukwakha nokulungisa izicubu zomzimba kubantu abadala. Kubizwa nangokuthi somatomedin.
Phakathi neminyaka yama-1990, abacwaningi baqala ukutadisha izinzuzo ze-IGF-1 supplementation, okubikwa ukuthi yayihlanganisa ukuthuthukiswa kwemizimba ye-muscle hypertrophy, ukulungisa izicubu kanye nokuphumula, phakathi kwabanye.
Ngokushesha, abakhiqizi abahlukahlukene babemikhiqizo yokuthengisa equkethe i-IGF-1 futhi ibizwa ngokuthi izondlo zokudla.
I-IGF-1 ibhekwa njengesidakamizwa esithuthukisa ukusebenza futhi ifakwe kwi-'Listed Material List List 'yeziningi zezinhlangano zezemidlalo ezihlelekile nezomsebenzi, kuhlanganise ne-National Football League, iKomiti Yezemidlalo Yomhlaba Wonke ne-World Anti-Doping Agency.
I-Deer Antler Spray ne-IGF-1
I-Deer antler spray, equkethe i-IGF-1, eyenziwe ngamaphephandaba abezindaba ngo-2011 ngemuva kokuthi imibiko ivele ukuthi uRay Lewis, umgcini we-linebacker we-Baltimore Ravens, wayexhunywe nomkhiqizo. Ngo-2013, i-Alabama Attorney General yavimbela i-SWATS Edge Performance Chips LLC ekuthengiseni i-IGF-1 ye-ant antler spray namathebulethi. Amasampula ahlolwe yi-Laboratory Medicine Research and Testing Laboratory eSalt Lake City athola ukuthi i-IGF-1 emikhiqizo yayingekho emfuthweni futhi cishe yayivela ezinkomeni noma kubantu. Isikhalazo sikhuluma ngezifundo zesayensi ezibonisa ukuthi zanda izingozi zomdlavuza we-colorectal, wamabele ne-prostate kubantu abanamazinga aphezulu e-IGF-1, kanye "nomonakalo emehlweni, izinhliziyo ezikhulisiwe, i-hypoglycemia, kanye ne-hyperglycemia."
I-Ultimate Spray ne-IGF-1
Esinye isifutho esiqukethe i-IGF-1, esibizwa ngokuthi "The Ultimate Spray," senze nezinhloko zokusetshenziswa kwabadlali abaningana be-NFL njengenye indlela eya ku-steroids.
Le mikhiqizo ayihambisani nomthetho, futhi akukho ukuphepha nokusebenza kwabo okungaziwa. Njengoba kubonakala, imithombo ye-IGF-1 ingaba yisilwane noma isintu naphezu kokuthengiswa njengokuvela kwezinyamazane.
Ukugxila okushiwo kungase kungabi okulungile. Indlela yokulethwa nayo ayinakuphika kusukela i-IGF-1 ingase ingaxhunyiwe emzimbeni phezulu futhi uma ithathwe ipilisi ingase iphulwe esiswini noma emathunjini futhi ingabanjwa. Ngokuvamile kunikezwa njengemijovo ekwelapheni izingane ezinezinkinga ezingakwazi ukubhekana nazo. Kodwa-ke, mhlawumbe isimo esibi kakhulu sikhona uma imikhiqizo empeleni ikhulisa amazinga e-IGF-1 emzimbeni, njengoba lokho kuphethe izingozi eziningi zempilo.
Izingozi zezempilo zezinga eliphakeme le-IGF-1
Uma imikhiqizo yokuthuthukisa ukusebenza iqukethe i-IGF-1 futhi ungayifaka emzimbeni wakho, inezenzo eziningi ezingaphezu kwalokho okufunayo ekwakheni imisipha nokubuyiselwa ekulimaleni. Ukuthatha i-IGF-1 ngobuningi obuningi kunezingozi eziningi ezaziwayo, ezihlanganisa izinhliziyo, izinkinga ze-neuromuscular, nezinkinga ze-endocrine / ze-metabolic.
Isishwankathelo sobufakazi be-epidemiological sithi izibonakaliso ze-anabolic ze-IGF-1 zingakhuthaza ukuthuthukiswa kwezicubu ngezindlela ezimbili, ngokuvimbela ukufa kweseli nokukhuthaza ukukhula kweseli. Zombili lezi zenzo zinganikeza amangqamuzana amathumba amaningi ithuba lokuphila, ukukhiqiza, nokuhlasela ezinye izicubu. Izingozi zamanqamu we-colon, ama-pancreas, i-endometrium, isifuba ne-prostate yanda njengoba unayo i-IGF-1 ehamba phambili ohlelweni lwakho.
Amazinga engokwemvelo nomsebenzi we-IGF-1 atholakala ekudleni okungakanani, kungakhathaliseki ukuthi ukudla kuphezulu kumaprotheni ezinkomo, kanye namazinga akho omzimba womzimba.
