Phakathi kwezongezelelo ezithandwayo ezisetyenziselwa ukunyusa ukubuyisela umthambo ngabadlali, i-lycopene, i-carotenoid efunyenwe kwiitamatato, isetyenziswa ngokubanzi, kunye nophando lweklinikhi olubonisa ukuba izongezo ze-lycopene ezicocekileyo ziyi-antioxidant enamandla enokunciphisa umthambo we-lipid peroxidation (indlela apho ii-radicals zasimahla zonakalisa iiseli "ngokuba" ii-electron kwi-lipids kwiinwebu zeseli).
Kuphononongo olutsha lokulinga, olupapashwe kwiJournal ye-International Society of Sports Nutrition, abaphandi bajonge ukuphanda ngezibonelelo ze-antioxidant ze-lycopene, kodwa ngokukodwa, ukuba baqokelele njani ngokuchasene ne-tomato powder, isongezelelo setumata kufutshane nemvelaphi yayo yonke yokutya equlethe. kungekuphela nje i-lycopene kodwa iprofayili ebanzi ye-micronutrients kunye nezinto ezahlukeneyo ze-bioactive.
Kwisifundo se-crossover esingahleliwe, esiphindwe kabini, abadlali be-11 abaqeqeshelwe kakuhle abagijimi bafumana iimvavanyo ezintathu zokuzilolonga ngokugqithiseleyo emva kweveki yokongeza kunye ne-tomato powder, emva koko i-lycopene yongezelela, kunye ne-placebo. Iisampulu ezintathu zegazi (isiseko, i-post-eyestion, kunye ne-post-exercise) zithathwe kwi-supplement ngayinye esetyenzisiweyo, ukwenzela ukuvavanya umthamo we-antioxidant opheleleyo kunye nokuguquguquka kwe-lipid peroxidation, njenge-malondialdehyde (MDA) kunye ne-8-isoprostane.
Kwiimbaleki, i-tomato powder iphucule umthamo opheleleyo we-antioxidant nge-12%. Okubangel 'umdla kukuba, unyango lwe-tomato powder luye lwakhokelela ekunciphiseni kakhulu ukuphakama kwe-8-isoprostane xa kuthelekiswa neyongezelelweyo ye-lycopene kunye ne-placebo. I-powder ye-tomato nayo yanciphisa kakhulu i-MDA yokuzivocavoca ngokuthelekiswa ne-placebo, nangona kunjalo, akukho mahluko anjalo abonakaliswe phakathi kwe-lycopene kunye ne-placebo yonyango.
Ngokusekelwe kwiziphumo zophononongo, ababhali bagqibe kwelokuba inzuzo enkulu kakhulu ye-tomato powder enayo kwi-antioxidant ye-antioxidant kunye ne-peroxidation eyenziwa ngumzimba inokuthi iziswe yintsebenziswano ye-synergistic phakathi kwe-lycopene kunye nezinye izondlo ze-bioactive, kunokuba i-lycopene kwindawo eyedwa. ifomathi.
"Sifumene ukuba ukuxhaswa kweeveki ze-1 kunye ne-tomato powder ngokuqinisekileyo kwandiswe amandla okulwa ne-antioxidant kwaye kwakunamandla ngakumbi xa kuthelekiswa nokuxhaswa kwe-lycopene," ababhali bolu phando bathi. "Ezi zikhokelo kwi-8-isoprostane kunye ne-MDA zixhasa ingcamango yokuba ngexesha elifutshane, i-tomato powder, kungekhona i-lycopene yokwenziwa, inamandla okunciphisa i-lipid peroxidation eyenziwa ngumzimba. I-MDA yi-biomarker ye-oxidation ye-lipid pools kodwa i-8-isoprostane yeyeklasi ye-F2-isoprostane kwaye i-biomarker ethembekileyo ye-radical-induced reaction ebonisa ngokukodwa i-oxidation ye-arachidonic acid.
Ngobufutshane bexesha lokufunda, ababhali baye benza i-hypothesize, nangona kunjalo, ukuba irejimeni yokongeza ixesha elide le-lycopene inokubangela iingenelo ezinamandla ze-antioxidant kwisondlo esizimeleyo, ngokuhambelana nezinye izifundo eziye zaqhutywa kwisithuba seeveki ezininzi. . Nangona kunjalo, i-tomato epheleleyo iqulethe iikhompawundi zeekhemikhali ezinokuphucula iziphumo eziluncedo kwi-synergy xa kuthelekiswa nekhompawundi enye, ababhali bathi.
