Lokhu kungqondo yakho ekudleni okulula: Ukuvuselelwa kobuchopho kuthinta ukufisa nokusebenzisa
Ukuvuselelwa kwamandla kazibuthe kwendawo yobuchopho okubandakanyeka "ekusebenzeni okuphezulu" kuthinta izifiso nokusetshenziswa kokudla okulula okuminyene kwekhalori, kubika ucwaningo kumagazini kaSepthemba I-Psychosomatic Medicine: I-Journal of Biobehaumcal Medicine, iphephabhuku elisemthethweni le-American Psychosomatic Society.
Ngemuva kokuvuselelwa kwe i-dorsolateral prefrontal cortex (DLPFC), amava abesifazane abasebasha anda izifiso ukudla okulula okunama-kilojoule amaningi — futhi udle okuningi kwalokho kudla lapho unikezwa ithuba, ngokocwaningo olwenziwe ngabaphenyi base-University of Waterloo, Ont., Canada. “Lokhu okutholakele kusikhanyisela ngendima ye-DLPFC ku izinkanuko zokudla (thokozisa ngokukhethekile ukulindela), ukusetshenziswa kokudla okukhangayo okuphezulu, nobuhlobo phakathi kokuzithiba kanye ukusetshenziswa ukudla, ”Kubhala abacwaningi. Umbhali omkhulu kwakunguPeter Hall, PhD.
Ukukhuthazwa kobuchopho kuthinta izifiso nokusetshenziswa kokudla okulula 'okunomsoco'
Ucwaningo lubandakanya abesifazane abasebasha abangama-21, abakhethiwe ngoba babike izifiso eziqinile futhi ezivamile zoshokoledi namazambane amazambane. Okunjalo okunomsoco, ikhalori-obukhulu Ukudla okulula zivame ukufakwa ekuthuthukiseni ukukhuluphala.
Abesifazane bakhonjiswe izithombe zalokhu kudla ukuvusa izifiso. Abaphenyi babe sebesebenzisa uhlobo lwe ukuvusa amandla kazibuthe, okubizwa ngokuthi yi-theta-burst stimulation eqhubekayo, ukwehlisa umsebenzi ku-DLPFC. Ucwaningo lwangaphambilini luveze ukuthi umsebenzi we-DLPFC ubamba iqhaza ekulawuleni ukudla izinkanuko.
Ngemuva kokukhuthazeka kwe-theta-burst, abesifazane babike izifiso ezinamandla zokudla — ikakhulukazi ushokoledi wobisi "onomsoco" namachips amazambane. Ngesikhathi sokuhlolwa kokunambitha okwalandela, bakudla okuningi kwalokhu kudla, kunokunye ukudla, ukudla okunganciphisi (ushokoledi omnyama kanye namaqhekeza kasoda).
Ukukhuthazwa kokwenza buthaka umsebenzi we-DLPFC kuphinde kuhlotshaniswe nokusebenza okuphansi esivivinyweni samandla wokulawula okuvimbelayo (isivivinyo seStroop). Umsebenzi owehlisiwe we-DLPFC ubonakale uhlotshaniswa "nokuzwela komvuzo" okwandisiwe-kwenze ababambiqhaza "bazwele kakhulu ezakhiweni ezinomvuzo zokudla okunomsoco ophezulu wekhalori," kubhala abacwaningi.
Umsebenzi Obuthakathaka Weqhaza Ungasiza Emngceleni Wokukhuluphala Ngokweqile
Imiphumela igqamisa iqhaza lomsebenzi ophethe ekulawuleni "ukuzibamba kokudla," abacwaningi bakholelwa. Umsebenzi ophetheyo, ofaka i-DLPFC, ubhekisa kusethi yemisebenzi yokuqonda enika amandla ukulawula "phezulu phezulu" kwesenzo, imizwa, nokucabanga.
"Ezingeni le-neurobiological eyisisekelo," ucwaningo lunikeza ubufakazi obuqondile bokuthi i-DLPFC ibandakanyekile esicini esisodwa sokulangazelela ukudla: ukulindela umvuzo. Abantu abanobuthakathaka umsebenzi omkhulu kungenzeka kungabi nokuzithiba ekudleni okudingekayo ukuze kulawulwe ukusetshenziswa kokudla okulula “endaweni yanamuhla ye-obesogenic.” Ebhekene nezinkomba eziqhubekayo namathuba okudla ukudla okuminyene namandla, abantu abanjalo bangaba sethubeni lokukhuluphala ngokweqile noma abakhuluphele.
Imiphumela iphakamisa ukuthi ukungenelela okuhlose ukuthuthukisa noma ukugcina umsebenzi we-DLPFC kungasiza ekuvimbeleni ukukhuluphala nezifo ezihlobene nakho. Ezimweni ezinjengesifo sikashukela sohlobo lwe-2, lapho imikhuba yokudla enempilo ibalulekile ekulawuleni izifo ngempumelelo, "Ukungenelela okugxile ekuthuthukiseni umsebenzi we-DLPFC, ngokusebenzisa ukuvivinya umzimba noma ezinye izindlela, kungaholela ekwandeni kokuzithiba kokudla futhi kamuva kuthuthukise ukuphathwa kwezifo," uDkt. IHholo nama-coauthor ayengeza.
Ukwaziswa okwengeziwe: "Imiphumela Yokukhuthazeka Okuqhubekayo KweTheta Burst kuya Kwesobunxele Kwedorsolateral Prefrontal Cortex Kumsebenzi Ophethe, Ukulangazelela Ukudla, Nokusetshenziswa Kokudla Okudliwayo" iphephabhuku.lww.com/psychosomatic ...... t_Stimulation.6.aspx
