Ukulungelelaniswa kwamehlo kubhekisa ekukwazini ukucubungula ulwazi olufunyenwe ngamehlo ukuze kulawulwe, uqondise kwaye ukhokele iintshukumo zezandla.
I-Astaxanthin, i-lutein kunye ne-zeaxanthin zizondlo ze-carotenoid ezaziwa ngokuba luncedo kwimpilo yamehlo.
Ukuphanda imiphumo yesondlo sokutya kwezi zintathu zondlo kukulungelelaniswa kwamehlo kunye nokulandelwa kwamehlo agudileyo emva komsebenzi we-VDT, uvavanyo lweklinikhi oluyimfama oluphindwe kabini, olulawulwa yi-placebo lwenziwa.
Ukususela ngomhla wama-28 kuMatshi ukuya kumhla wesi-2 kuJulayi 2022, iJapan Sports Vision Association eTokyo yenza uphando kumadoda namabhinqa aseJapan asempilweni aphakathi kweminyaka engama-20 nama-60 ubudala. iikhompyutha ezisetyenzisiweyo, okanye ii-VDT ezisetyenzisiweyo emsebenzini.
Itotali ye-28 kunye ne-29 abathathi-nxaxheba babelwa ngokungaqhelekanga kumaqela asebenzayo kunye ne-placebo, ngokulandelanayo.
Iqela elisebenzayo lafumana i-softgels equkethe i-6mg i-astaxanthin, i-10mg lutein, kunye ne-2mg zeaxanthin, ngelixa iqela le-placebo lafumana i-softgels equkethe ioli ye-rice bran. Izigulane kumaqela omabini zathatha i-capsule kanye ngosuku kwiiveki ezisibhozo.
Umsebenzi obonakalayo kunye ne-macular pigment optical density (MAP) zavavanywa kwisiseko kunye neeveki ezimbini, ezine, kunye nesibhozo emva kokuxhaswa.
Umsebenzi wabathathi-nxaxheba be-VDT ubuquka ukudlala umdlalo wevidiyo kwi-smartphone imizuzu engama-30.
Emva kweeveki ezisibhozo, iqela lomsebenzi lalinexesha elincinane lokulungelelaniswa kwamehlo (21.45 ± 1.59 imizuzwana) kuneqela le-placebo (22.53 ± 1.76 imizuzwana). googletag.cmd.push(umsebenzi () {googletag.display('text-ad1′); });
Ukongezelela, ukuchaneka kokulungelelaniswa kwesandla-kwamehlo emva kwe-VDT kwiqela elisebenzayo (83.72±6.51%) laliphezulu kakhulu kuneqela le-placebo (77.30±8.55%).
Ukongeza, kukho ukwanda okukhulu kwe-MPOD, elinganisa ubuninzi be-retinal macular pigment (MP), kwiqela elisebenzayo. I-MP yenziwe yi-lutein kunye ne-zeaxanthin, efunxa ukukhanya okuluhlaza okuyingozi. I-denser it, inamandla ngakumbi umphumo wayo wokukhusela uya kuba.
Utshintsho kumanqanaba eMPOD ukusuka kwisiseko kwaye emva kweeveki ezisibhozo ziphezulu kakhulu kwiqela elisebenzayo (0.015 ± 0.052) xa kuthelekiswa neqela le-placebo (-0.016 ± 0.052).
Ixesha lokuphendula kwi-visuo-motor stimuli, njengoko lilinganiswe ngokulandelelwa kakuhle kweentshukumo zamehlo, alizange libonise ukuphucuka okubalulekileyo emva kokuxhaswa kulo naliphi na iqela.
"Olu pho nonongo luxhasa i-hypothesis yokuba umsebenzi we-VDT uphazamisa okwethutyana ukulungelelaniswa kwamehlo kunye nokulandelwa kwamehlo agudileyo, kwaye ukuxhaswa nge-astaxanthin, i-lutein, kunye ne-zeaxanthin kunceda ukunciphisa ukulungelelaniswa kwesandla se-VDT-induced eye-eye," watsho umbhali. .
Ukusetyenziswa kwe-VDTs (kubandakanywa iikhomputha, ii-smartphones kunye neetafile) ziye zaba yinxalenye yendlela yokuphila yanamhlanje.
Ngelixa ezi zixhobo zibonelela ngokulula, zonyusa ukusebenza kakuhle, kunye nokunciphisa ukubekwa wedwa kwezentlalo, ngakumbi ngexesha lobhubhani, izifundo ezahlukeneyo zibonise ukuba umsebenzi we-VDT ixesha elide unokuchaphazela kakubi umsebenzi wokubonwayo.
"Ke ngoko, siqikelela ukuba umsebenzi womzimba owonakaliswa ngumsebenzi we-VDT unokunciphisa ulungelelwaniso lwezandla zamehlo, kuba le yokugqibela ihlala ihambelana nokushukuma komzimba," bongeza ababhali.
Ngokwezifundo zangaphambili, i-astaxanthin yomlomo inokubuyisela indawo yokuhlala yamehlo kwaye iphucule iimpawu ze-musculoskeletal, ngelixa i-lutein kunye ne-zeaxanthin ziye zaxelwa ukuba ziphucule isantya sokucwangcisa umfanekiso kunye novelwano oluchaseneyo, zonke ezichaphazela ukuphendula kwe-visuomotor.
Ukongeza, kukho ubungqina bokuba umthambo oqinileyo uyonakalisa umbono wokubonwayo we-peripheral ngokunciphisa i-oxygenation yobuchopho, nto leyo enokuphazamisa ulungelelwaniso lwezandla zamehlo.
"Ke ngoko, ukuthatha i-astaxanthin, i-lutein, kunye ne-zeaxanthin kunokunceda ukuphucula ukusebenza kweimbaleki ezifana ne-tennis, i-baseball, kunye nabadlali be-esports," ababhali bayachaza.
Kufuneka kuqatshelwe ukuba uphononongo lwalunemida ethile, kubandakanywa akukho zithintelo zokutya kubathathi-nxaxheba. Oku kuthetha ukuba banokutya izondlo ngexesha lokutya kwabo kwemihla ngemihla.
Ukongezelela, akucaci ukuba ngaba iziphumo ziyi-additive okanye i-synergistic effect yazo zonke izondlo ezintathu kunempembelelo yesondlo esisodwa.
“Sikholelwa ukuba indibaniselwano yezi zondlo zibalulekile ekuchaphazeleni ulungelelwaniso lwezandla zamehlo ngenxa yeendlela ezahlukeneyo zokwenza. Nangona kunjalo, uphando olongezelelweyo luyafuneka ukucacisa iindlela eziphantsi kwemiphumo emihle, "ababhali baphetha.
"Iimpembelelo ze-astaxanthin, i-lutein, kunye ne-zeaxanthin kukulungelelaniswa kwesandla samehlo kunye nokulandelwa kwamehlo agudileyo emva kokubonakaliswa okubonakalayo kwizifundo eziphilileyo: uvavanyo olungenamkhethe, oluyimfama oluphindwe kabini, olulawulwa yi-placebo".
