Phakathi kwezithako zokudla okunomsoco ezithandwayo ezisetshenziselwa ukwandisa ukuvivinya umzimba ngabasubathi, i-lycopene, i-carotenoid etholakala kutamatisi, isetshenziswa kabanzi, ngocwaningo lwezokwelapha olufakazela ukuthi izithako ze-lycopene ezihlanzekile ziyi-antioxidant enamandla enganciphisa ukuzivocavoca kwe-lipid peroxidation (indlela lapho ama-radicals mahhala alimaza amangqamuzana "ngokweba" ama-electron ku-lipids kulwelwesi lwamaseli).
Ocwaningweni olusha lomshayeli, olwanyatheliswa kuyi-Journal of the International Society of Sports Nutrition, abacwaningi bahlose ukuphenya izinzuzo ze-antioxidant ze-lycopene, kodwa ikakhulukazi, ukuthi zinqwabelane kanjani ngokumelene ne-tomato powder, isengezo sikatamatisi esiseduze nemvelaphi yayo yonke yokudla equkethe. hhayi i-lycopene kuphela kodwa iphrofayili ebanzi ye-micronutrients kanye nezingxenye ezihlukahlukene ze-bioactive.
Esifundweni se-crossover esingahleliwe, esiphuphuthekiswe kabili, abasubathi besilisa abaqeqeshwe kahle be-11 bathola izivivinyo ezintathu eziphelele zokuzivocavoca ngemva kwesonto lokwengeza nge-powder powder, kwase kuba isithasiselo se-lycopene, kanye ne-placebo. Amasampula egazi amathathu (isisekelo, i-post-ininged, kanye ne-post-exercise) athathwe ngayinye yezithako ezisetshenzisiwe, ukuze kuhlolwe umthamo ophelele we-antioxidant kanye nokuguquguquka kwe-lipid peroxidation, njenge-malondialdehyde (MDA) ne-8-isoprostane.
Kwabasubathi, impushana katamatisi ithuthukise umthamo we-antioxidant ngo-12%. Kuyathakazelisa ukuthi ukwelashwa kwe-tomato powder nakho kubangele ukuphakama okuncishisiwe kakhulu kwe-8-isoprostane uma kuqhathaniswa kokubili okungeziwe kwe-lycopene kanye ne-placebo. I-tomato powder iphinde yanciphisa kakhulu umsebenzi ophelele we-MDA uma kuqhathaniswa ne-placebo, noma kunjalo, akukho mehluko onjalo obonisiwe phakathi kwe-lycopene ne-placebo yokwelashwa.
Ngokusekelwe emiphumeleni yocwaningo, ababhali baphetha ngokuthi izinzuzo ezinkulu kakhulu ze-tomato powder ezazinazo kumthamo we-antioxidant kanye ne-peroxidation eyenziwe ngokuzivocavoca kungenzeka ukuthi ilethwe ukuxhumana phakathi kwe-lycopene nezinye izakhi ze-bioactive, kunokuba i-lycopene endaweni engayodwa. ifomethi.
"Sithole ukuthi ukwesekwa kweviki le-1 nge-tomato powder kwandise amandla aphelele e-antioxidant futhi kwakunamandla kakhulu uma kuqhathaniswa ne-lycopene supplementation," kusho abalobi bocwaningo. "Lezi zindlela ku-8-isoprostane kanye ne-MDA zisekela umbono wokuthi esikhathini esifushane, i-tomato powder, hhayi i-lycopene yokwenziwa, inamandla okunciphisa i-lipid peroxidation eyenziwe ngokuzivocavoca. I-MDA iyi-biomarker ye-oxidation yamachibi aphelele e-lipid kodwa i-8-isoprostane ingeyesigaba se-F2-isoprostane futhi iyisici esithembekile se-biomarker yokusabela okubangelwa ama-radical ebonisa ngokuqondile i-oxidation ye-arachidonic acid.
Ngobufushane besikhathi sokufunda, ababhali benza i-hypothesize, nokho, ukuthi uhlobo lwe-supplementation yesikhathi eside lwe-lycopene lungabangela izinzuzo ezinamandla ze-antioxidant kumsoco ohlukanisiwe, ngokuhambisana nezinye izifundo ezenziwa esikhathini esingamaviki ambalwa. . Noma kunjalo, utamatisi ophelele uqukethe amakhemikhali amakhemikhali angathuthukisa imiphumela enenzuzo ku-synergy uma kuqhathaniswa nenhlanganisela eyodwa, abalobi bathi.
