Kugwirizana kwa maso ndi dzanja kumatanthauza luso lotha kugwiritsa ntchito chidziwitso cholandiridwa kudzera m'maso kuti chiwongolere, kuwongolera, ndikuwongolera mayendedwe a manja.
Astaxanthin, lutein ndi zeaxanthin ndi michere ya carotenoid yomwe imadziwika kuti ndi yothandiza pa thanzi la maso.
Pofuna kufufuza zotsatira za zakudya zowonjezera zakudya zitatuzi pa mgwirizano wa maso ndi manja komanso kutsatira bwino maso pambuyo pa ntchito ya VDT, kuyesedwa kwachipatala komwe kunayang'aniridwa ndi placebo kunachitika.
Kuyambira pa Marichi 28 mpaka Julayi 2, 2022, bungwe la Japan Sports Vision Association ku Tokyo linachita kafukufuku wa amuna ndi akazi athanzi aku Japan azaka zapakati pa 20 ndi 60. Anthu omwe anali ndi maso owonera patali anali ndi maso okwana 0.6 kapena kupitirira apo ndipo nthawi zonse ankasewera masewera apakanema, ankagwiritsa ntchito makompyuta, kapena ankagwiritsa ntchito ma VDT pantchito.
Anthu onse 28 ndi 29 adapatsidwa mwachisawawa m'magulu omwe amagwira ntchito komanso omwe adalandira placebo, motsatana.
Gulu lomwe linkagwira ntchito linalandira ma softgel okhala ndi 6mg astaxanthin, 10mg lutein, ndi 2mg zeaxanthin, pomwe gulu la placebo linalandira ma softgel okhala ndi mafuta a mpunga. Odwala m'magulu onse awiriwa anamwa kapisozi kamodzi patsiku kwa milungu isanu ndi itatu.
Ntchito yowoneka bwino komanso kuchuluka kwa macular pigment optical density (MAP) zinayesedwa poyambira komanso milungu iwiri, inayi, ndi isanu ndi itatu mutalandira chithandizo.
Zochita za ophunzira a VDT zinali kusewera masewera apakanema pa foni yam'manja kwa mphindi 30.
Pambuyo pa milungu isanu ndi itatu, gulu la zochita linali ndi nthawi yochepa yogwirizanitsa maso ndi dzanja (masekondi 21.45 ± 1.59) kuposa gulu la placebo (masekondi 22.53 ± 1.76). googletag.cmd.push(function () { googletag.display('text-ad1′); });
Kuphatikiza apo, kulondola kwa mgwirizano wa dzanja ndi maso pambuyo pa VDT m'gulu logwira ntchito (83.72±6.51%) kunali kwakukulu kwambiri kuposa m'gulu la placebo (77.30±8.55%).
Kuphatikiza apo, panali kuwonjezeka kwakukulu kwa MPOD, yomwe imayesa kuchuluka kwa retina macular pigment (MP), mu gulu lomwe likugwira ntchito. MP imapangidwa ndi lutein ndi zeaxanthin, zomwe zimayamwa kuwala koipa kwa buluu. Ikakhala yokhuthala, chitetezo chake chimakhala champhamvu kwambiri.
Kusintha kwa milingo ya MPOD kuyambira koyambira komanso pambuyo pa milungu isanu ndi itatu kunali kwakukulu kwambiri mu gulu logwira ntchito (0.015 ± 0.052) poyerekeza ndi gulu la placebo (-0.016 ± 0.052).
Nthawi yoyankha ku zinthu zoyambitsa visuo-motor, monga momwe zimayesedwera potsatira mayendedwe a maso osavuta, sinawonetse kusintha kwakukulu pambuyo powonjezera m'magulu onse awiri.
"Kafukufukuyu akuchirikiza lingaliro lakuti ntchito ya VDT imasokoneza kwakanthawi mgwirizano wa maso ndi dzanja komanso kutsatira bwino maso, komanso kuti kuwonjezera astaxanthin, lutein, ndi zeaxanthin kumathandiza kuchepetsa kuchepa kwa mgwirizano wa maso ndi dzanja chifukwa cha VDT," adatero wolembayo.
Kugwiritsa ntchito ma VDT (kuphatikizapo makompyuta, mafoni a m'manja ndi mapiritsi) kwakhala gawo lofala la moyo wamakono.
Ngakhale kuti zipangizozi zimathandiza kuti zinthu ziyende bwino, zimawonjezera mphamvu, komanso zimachepetsa kudzipatula, makamaka panthawi ya mliri, maphunziro osiyanasiyana asonyeza kuti kuchita zinthu kwa nthawi yayitali kwa VDT kungasokoneze kwambiri ntchito yowona.
"Chifukwa chake, tikuganiza kuti ntchito yakuthupi yomwe yasokonekera ndi ntchito ya VDT ingachepetse mgwirizano wa maso ndi manja, popeza izi nthawi zambiri zimagwirizanitsidwa ndi mayendedwe a thupi," olembawo adawonjezera.
Malinga ndi kafukufuku wakale, astaxanthin yokamwa imatha kubwezeretsa malo ogona maso ndikuchepetsa zizindikiro za minofu ndi mafupa, pomwe lutein ndi zeaxanthin zanenedwa kuti zimathandizira kuti zithunzi zisinthe mwachangu komanso kuti zisamawoneke bwino, zomwe zimakhudza momwe zinthu zimachitikira ndi visuomotor.
Kuphatikiza apo, pali umboni wakuti kuchita masewera olimbitsa thupi kwambiri kumasokoneza kuona bwino kwa maso mwa kuchepetsa mpweya muubongo, zomwe zingasokoneze mgwirizano wa maso ndi manja.
"Chifukwa chake, kumwa astaxanthin, lutein, ndi zeaxanthin kungathandizenso kukonza magwiridwe antchito a othamanga monga tenisi, baseball, ndi osewera a esports," olembawo akufotokoza.
Tiyenera kudziwa kuti kafukufukuyu anali ndi zoletsa zina, kuphatikizapo palibe zoletsa zakudya kwa ophunzirawo. Izi zikutanthauza kuti akhoza kudya zakudya zopatsa thanzi pa chakudya chawo cha tsiku ndi tsiku.
Kuphatikiza apo, sizikudziwika bwino ngati zotsatira zake ndi zowonjezera kapena zogwirizana ndi michere yonse itatu m'malo mokhala ndi zotsatira za michere imodzi.
"Timakhulupirira kuti kuphatikiza kwa michere iyi ndikofunikira kwambiri pakukhudza mgwirizano wa maso ndi manja chifukwa cha njira zosiyanasiyana zogwirira ntchito. Komabe, maphunziro ena akufunika kuti afotokoze njira zomwe zimapangitsa kuti phindu likhalepo," olembawo adamaliza.
"Zotsatira za astaxanthin, lutein, ndi zeaxanthin pa mgwirizano wa maso ndi manja ndi kutsata maso bwino pambuyo pa kusintha kwa mawonekedwe mwa anthu athanzi: kuyeserera kosankhidwa mwachisawawa, kopanda maso kawiri, koyendetsedwa ndi placebo".
