Njengamanje, umphakathi wethu ukhohlisiwe futhi ukholelwa ukuthi ukudla inyama kubaluleke kakhulu ekusekeleni ukuphila. Kulokhu, umbuzo uphakama: ingabe ukudla kwemifino kunganikeza inani lamaprotheni adingekayo ukuze kugcinwe ukuphila namandla? Buqine kangakanani ubudlelwano phakathi kwalokho esikudlayo neminyaka yokuphila?
UDkt. Bergstrom we-Institute of Physiology e-Stockholm wenze uchungechunge lwezivivinyo ezithakazelisa kakhulu. Wakhetha abasubathi abambalwa abakhokhelwayo. Kwakudingeka benze umsebenzi ku-ergometer yebhayisikili enomthwalo wama-70% wamakhono abo angokomzimba. Kubhekwe ukuthi kuzothatha isikhathi esingakanani ukuthi kufike isikhathi sokukhathala, kuye ngezimo ezahlukene zokudla okunempilo kwabasubathi. (Ukukhathala kwachazwa njengokungakwazi ukumelana nomthwalo onikeziwe ngokuqhubekayo, futhi futhi njengesimo lapho izitolo ze-muscle glycogen ziqala ukuqedwa)
Ngesikhathi kulungiselelwa isigaba sokuqala sokuhlolwa, abasubathi baphiwa ukudla okuxubile kwesintu okuhlanganisa inyama, amazambane, izaqathi, imajarini, iklabishi nobisi. Isikhathi sokukhathala kulesi sigaba safika ngokwesilinganiso ngemva kwehora elingu-1 nemizuzu engama-54. Ngesikhathi sokulungiswa kwesigaba sesibili sokuhlolwa, abagijimi banikezwa ukudla okunekhalori ephezulu, okuhlanganisa inani elikhulu lamaprotheni namafutha ezilwane, okungukuthi: inyama, inhlanzi, ibhotela namaqanda. Lokhu kudla kwagcinwa izinsuku ezintathu. Njengoba ngokudla okunjalo, imisipha yabasubathi ayikwazanga ukuqongelela inani elidingekayo le-glycogen, ukukhathala kulesi sigaba kwenzeka ngemuva kwesilinganiso semizuzu engama-57.
Ukulungiselela isigaba sesithathu sokuhlolwa, abasubathi banikezwa ukudla okuqukethe inani elikhulu lama-carbohydrate: isinkwa, amazambane, ummbila, imifino ehlukahlukene nezithelo. Abasubathi bakwazi ukunyathela ngaphandle kokukhathala amahora ama-2 nemizuzu engama-47! Ngalokhu kudla, ukukhuthazela kukhuphuke cishe ngo-300% uma kuqhathaniswa nokudla amaprotheni anekhalori ephezulu nokudla okunamafutha. Ngenxa yalokhu kuhlola, uDkt. Per Olof Estrand, umqondisi we-Institute of Physiology eStockholm, wathi: “Singabacebisa ngani abasubathi? Khohlwa ngenganekwane yamaprotheni nokunye ukucwasa ... ". Omunye umsubathi ozacile waqala ukukhathazeka ngokuthi wayengenayo imisipha emikhulu njengemfashini eyayidingeka.
Ababehamba nabo ejimini bameluleka ngokuthi adle inyama. Umsubathi wayengumuntu odla imifino futhi ekuqaleni wenqaba lesi sipho, kodwa, ekugcineni, wavuma futhi waqala ukudla inyama. Cishe ngaso leso sikhathi, umzimba wakhe waqala ukukhula ngevolumu - namahlombe, nama-biceps, nemisipha ye-pectoral. Kodwa waqala ukuqaphela ukuthi ngokukhula kwemisipha, uphelelwa amandla. Ezinyangeni ezimbalwa kamuva, akakwazanga ukucindezela i-barbell ngamakhilogremu angu-9 ngaphezu kokujwayelekile - ngaphambi koshintsho ekudleni kwakhe - okujwayelekile.
Wayefuna ukubukeka emkhulu futhi enamandla, kodwa angaphelelwa amandla! Kodwa-ke, waqaphela ukuthi wayephenduka "i-puff pastry" enkulu. Ngakho wakhetha ukuqina ngempela kunokuba abonakale enjalo, futhi wabuyela ekudleni kwemifino. Ngokushesha, waqala ukulahlekelwa "ubukhulu", kodwa amandla akhe anda. Ekugcineni, akazange nje aphinde athole ikhono lakhe lokucindezela i-barbell 9 kilos ngaphezulu, kodwa wakwazi ukwengeza amanye ama-5 kilos, manje ecindezela ama-kilos angu-14 ngaphezu kwalokho lapho edla inyama futhi ekhudlwana ngevolumu.
Umbono wangaphandle oyiphutha ngokuvamile usebenza njengesivikelo sokuthi ukudla inani elikhulu lamaprotheni kuyafiseleka futhi kubalulekile. Ekuhlolweni kwezilwane, izilwane ezincane ezidla amaprotheni acebile zikhula ngokushesha okukhulu. Futhi lokhu, kubonakala, kuyamangalisa. Ubani ofuna ukuba mncane futhi abe mncane? Kodwa konke akulula kangako. Ukukhula ngokushesha okungaphezu kwalokho okuvamile ezilwaneni akusizi kangako. Ungakwazi ukukhula ngokushesha ngesisindo nokuphakama, kodwa izinqubo ezilimazayo zomzimba zingaqala ngokushesha nje. Ukudla okukhuthaza ukukhula okusheshayo akuyona indlela engcono kakhulu yokwandisa impilo. Ukukhula okusheshayo nokuphila okufushane kuhlale kuxhumene.
