Ukuxhumanisa iso nesandla kusho ikhono lokucubungula ulwazi olutholwe ngamehlo ukuze ulawule, uqondise, futhi uqondise ukunyakaza kwezandla.
I-Astaxanthin, i-lutein ne-zeaxanthin izakhi ze-carotenoid ezaziwa njengenzuzo empilweni yamehlo.
Ukuze uphenye imiphumela yokwengezwa kokudla kwalezi zondlo ezintathu ekusebenzisaneni kweso nesandla kanye nokulandela iso elibushelelezi kulandela umsebenzi we-VDT, ukuhlolwa komtholampilo okungaboni kabili, okulawulwa yi-placebo kwenziwa.
Kusukela ngoMashi 28 kuya kuJulayi 2, 2022, i-Japan Sports Vision Association e-Tokyo yenze inhlolovo yabesilisa nabesifazane baseJapane abanempilo ephakathi kweminyaka engu-20 nengu-60. Izihloko zazinombono webanga elingu-0.6 noma okungcono kuwo womabili amehlo futhi zazidlala njalo imidlalo yevidiyo, amakhompyutha asetshenzisiwe, noma ama-VDT asetshenziselwe umsebenzi.
Isamba sabahlanganyeli be-28 kanye ne-29 babelwa ngokungahleliwe kumaqembu asebenzayo kanye ne-placebo, ngokulandelana.
Iqembu elisebenzayo lithole ama-softgel aqukethe i-6mg astaxanthin, i-10mg lutein, ne-2mg zeaxanthin, kuyilapho iqembu le-placebo lathola ama-softgel aqukethe amafutha e-rice bran.Iziguli kuwo womabili amaqembu zathatha i-capsule kanye ngosuku amasonto ayisishiyagalombili.
Ukusebenza okubonakalayo kanye ne-macular pigment optical density (MAP) kwahlolwa ekuqaleni kanye namaviki amabili, amane, nayisishiyagalombili ngemva kokwengeza.
Umsebenzi wabahlanganyeli be-VDT ubuhlanganisa ukudlala igeyimu yevidiyo ku-smartphone imizuzu engama-30.
Ngemuva kwamasonto ayisishiyagalombili, iqembu lomsebenzi libe nesikhathi esincane sokusebenzisana kweso nesandla (imizuzwana engu-21.45 ± 1.59) kuneqembu le-placebo (amasekhondi angu-22.53 ± 1.76).googletag.cmd.push(umsebenzi () {googletag.display('text-ad1′); });
Ukwengeza, ukunemba kokubambisana kwesandla neso ngemuva kwe-VDT eqenjini elisebenzayo (83.72±6.51%) kwakuphakeme kakhulu kuneqembu le-placebo (77.30±8.55%).
Ngaphezu kwalokho, kube nokwanda okuphawulekayo kwe-MPOD, ekala ukuminyana kwe-retinal macular pigment (MP), eqenjini elisebenzayo.I-MP yakhiwe nge-lutein ne-zeaxanthin, edonsa ukukhanya okuluhlaza okulimazayo.Ukuqina kwayo, umphumela wayo wokuvikela uzoba namandla.
Izinguquko kumazinga e-MPOD kusukela kwesisekelo futhi ngemva kwamasonto ayisishiyagalombili zaziphakeme kakhulu eqenjini elisebenzayo (0.015 ± 0.052) uma kuqhathaniswa neqembu le-placebo (-0.016 ± 0.052).
Isikhathi sokuphendula kusisusa se-visuo-motor, njengoba silinganiswa ngokulandelela okushelelayo kokunyakaza kwamehlo, asizange sibonise ukuthuthuka okuphawulekayo ngemva kokwengezwa kunoma yiliphi iqembu.
"Lolu cwaningo lusekela i-hypothesis yokuthi umsebenzi we-VDT uphazamisa okwesikhashana ukusebenzisana kwamehlo kanye nokulandelela iso okushelelayo, nokuthi ukufakwa kwe-astaxanthin, i-lutein, ne-zeaxanthin kusiza ukunciphisa ukwehla kokuhlanganiswa kwesandla kwesandla se-VDT," kusho umbhali..
Ukusetshenziswa kwama-VDTs (okuhlanganisa amakhompyutha, ama-smartphones kanye namathebulethi) sekuyingxenye evamile yokuphila kwesimanje.
Ngenkathi lawa madivayisi enikeza ukunethezeka, akhuphule ukusebenza kahle, futhi anciphise ukuhlukaniswa nomphakathi, ikakhulukazi phakathi nobhubhane, ucwaningo oluhlukahlukene lubonise ukuthi umsebenzi we-VDT omude ungaba nomthelela omubi ekusebenzeni kokubuka.
"Ngakho-ke, sicabanga ukuthi umsebenzi womzimba ophazamisekile ngenxa yomsebenzi we-VDT ungase unciphise ukusebenzisana kwamehlo, ngoba lokhu okugcina kuvame ukuhlotshaniswa nokunyakaza komzimba," kunezela ababhali.
Ngokusho kocwaningo lwangaphambilini, i-astaxanthin yomlomo ingabuyisela indawo yokuhlala yamehlo futhi ithuthukise izimpawu ze-musculoskeletal, kuyilapho i-lutein ne-zeaxanthin kubikwe ukuthi ithuthukisa isivinini sokucubungula isithombe nokuzwela kokuqhathanisa, konke okuthinta ukusabela kwe-visuomotor.
Ngaphezu kwalokho, kunobufakazi bokuthi ukuvivinya umzimba okujulile kuphazamisa ukubona okubonakalayo okuseceleni ngokunciphisa umoya-mpilo wobuchopho, okungase kuthikameze ukusebenzisana kwamehlo nesandla.
Ngakho-ke, ukuthatha i-astaxanthin, i-lutein, ne-zeaxanthin nakho kungasiza ekuthuthukiseni ukusebenza kwabasubathi abafana nethenisi, i-baseball, nabadlali be-esports,” kuchaza ababhali.
Kufanele kuqashelwe ukuthi ucwaningo lwalunemikhawulo ethile, okuhlanganisa nokungabikho kwemikhawulo yokudla kwabahlanganyeli.Lokhu kusho ukuthi bangadla izakhamzimba ngesikhathi sokudla kwabo kwansuku zonke.
Ngaphezu kwalokho, akucaci ukuthi imiphumela ingumphumela ohlanganisayo noma we-synergistic wazo zonke izakhi ezintathu kunokuba umphumela wesakhi esisodwa esisodwa.
“Sikholelwa ukuthi ukuhlanganiswa kwalezi zakhi zomsoco kubalulekile ekuthinteni ukusebenzisana kwamehlo ngenxa yezindlela ezihlukene zokwenza.Kodwa-ke, ucwaningo olwengeziwe luyadingeka ukuze kucaciswe izindlela ezingaphansi kwemiphumela enenzuzo, ”kuphetha ababhali.
"Imiphumela ye-astaxanthin, i-lutein, ne-zeaxanthin ekusebenzisaneni kweso nesandla kanye nokulandela iso elibushelelezi kulandela ukukhohliswa kwesiboniso esihlokweni esinempilo: isilingo esilawulwa ngokungahleliwe, esingaboni kabili, esilawulwa yi-placebo".

Izihloko Ezihlobene Izithasiselo Zocwaningo Zezempilo ZaseMpumalanga Asia Izimangalo Zama-Antioxidant ZaseJapane kanye Ne-Carotenoids Yempilo Yamehlo
Ucwaningo olusha lubonisa ukuthi i-Pycnogenol® French Maritime Pine Bark Extract ingase iphumelele ekulawuleni ukushuba ngokweqile kanye nokuthatheka ezinganeni ezineminyaka engu-6 kuya ku-12…
