Njengoba kufika isizini yokuqeqeshwa yasehlobo, ukuphepha kwezemidlalo kuthola ukunakwa okungakaze kubonwe. Isikrini sokushisa sembulunga emnyama esimanzi (i-WBGT) esikwazi ukulinganisa ngokuphelele izinga lokushisa, umswakama, ukushisa okukhanyayo kanye nesivinini somoya sithandwa kakhulu ezikoleni kuwo wonke amazinga nasemaqenjini ezemidlalo ochwepheshe, sinikeza abadlali "isambulela sesayensi sokuvikela ukushisa".
Ithimba Lomgijimi Nensimu YaseYunivesithi: “Umthumeli” Wokuqeqeshwa Kwesayensi
Enkundleni yezemidlalo yaseTsinghua University, i-WBGT monitor esanda kufakwa iba “umlawuli wesayensi” wamalungiselelo okuqeqesha. Le divayisi iqapha futhi ibonise inkomba ye-WBGT yendawo ngesikhathi sangempela. Abaqeqeshi bahlukanisa ukuqina kokuqeqeshwa kube amazinga amane: okuluhlaza okotshani, okuphuzi, okuwolintshi nokubomvu ngokusekelwe kudatha. Lapho inkomba ingena endaweni yesixwayiso esiwolintshi, lungisa ngokushesha uhlelo lokuqeqesha, shintsha ukukhuthazela kokugijima kube ukuqeqeshwa kobuchwepheshe, bese uphoqa amalungu eqembu ukuthi agcwalise amanzi njalo ngemizuzu engama-20. Lapho umugqa wesixwayiso esibomvu usufinyelelwe, konke ukuqeqeshwa kwangaphandle kosuku kuzokhanselwa ngokuzenzakalelayo. Lolu hlelo lunciphise ukwanda kwezifo ezihlobene nokushisa eqenjini ngo-70% unyaka nonyaka.
Ukuqeqeshwa kwentsha ezikoleni zezemidlalo: “Abaqaphi” Babadlali Abasha
Ezikoleni zezemidlalo, uhlelo lokuqapha lwe-WBGT luhlanganiswe ngokujulile nohlelo lokuphatha ukuqeqeshwa. Ngaphezu kokusetha izindawo zokuqapha ezihleliwe endaweni yokuqeqesha, amadivayisi aphathekayo nawo afakwe ukuqapha okuhambayo phakathi kwezindawo ezahlukene. I-"Summer Training Management Measures" yakamuva ebuyekeziwe yesikole ibeka ngokusobala ukuthi konke ukuqeqeshwa kwangaphandle kumele kwenziwe ngokuhambisana nenkomba ye-WBGT: lapho inkomba idlula ama-28℃, ukuqeqeshwa kokukhuthazela kufanele kumiswe. Lapho izinga lokushisa lidlula ama-30℃, ukuqeqeshwa kwangaphandle kwabafundi abangaphansi kweminyaka engu-15 kufanele kumiswe ngokushesha. Lolu hlelo luye lwaqashelwa ngazwi linye ngabaqeqeshi nabazali.
Imfundo Yomzimba Yesikole Samabanga Aphakathi: “Inethi Yokuphepha” Yokuqeqeshwa Kokuhlolwa Kokungena Esikoleni Samabanga Aphezulu
Ukuphendula ukuqeqeshwa kokungena esikoleni samabanga aphezulu semfundo yokuzivocavoca yasehlobo, izikole eziningi eziphakathi ziye zethula ngokuhlanganyela uhlelo lokuxwayisa kwasekuqaleni lwe-WBGT. Amaqembu okufundisa ngokomzimba esikole ngasinye asemise indlela yokuxhumanisa. Lapho uhlelo lokuqapha lukhipha isexwayiso sokushisa okuphezulu, zonke izikole esifundeni zizolungisa amalungiselelo azo okuqeqesha ngasikhathi sinye. Enyangeni yokuqala yokusebenza, uhlelo lukhiphe ngempumelelo izixwayiso ezintathu ngesimo sezulu esishisa kakhulu, lusiza izikole ukuthi zithuthe ngokushesha ukuqeqeshwa ngaphakathi futhi zivimbele cishe abafundi abayinkulungwane ekuqeqeshweni ezindaweni eziyingozi.
Amaqembu ezemidlalo ochwepheshe: “Indinganiso Entsha” Yokuvikela Okunembile
Esizindeni sokuqeqesha seqembu lebhola lezinyawo labesifazane likazwelonke, ukuqapha i-WBGT kuhlanganiswe kuzo zonke izici zokuqeqeshwa kwansuku zonke. Ngokuhlaziya idatha yomlando, udokotela weqembu uthole ukuthi isikhathi esisukela ngo-2 kuya ku-4 ntambama yisikhathi esinengozi ephezulu kakhulu yokushisa ngosuku. Ngokusekelwe kulokhu, ukuqeqeshwa okunamandla kakhulu kwalungiswa ukuze kwenziwe ekuseni nakusihlwa. Phakathi naleso sikhathi, ithimba lezokwelapha lakha izinhlelo zokuhlanza amanzi ezihlukene ngokusekelwe emthwalweni wokugijima ezindaweni ezahlukene, okwakhulisa ukusebenza kwabadlali ezindaweni ezishisa kakhulu ngo-15%.
Impumelelo kanye namathemba
Ngokwezibalo, ngemva kokusetshenziswa ngokugcwele kohlelo lokuqapha lwe-WBGT, isilinganiso sokuvama kwezifo zokushisa ezibangelwa ukuvivinya umzimba kumayunithi okuhlola sehle ngo-65%, kanti izinga lokuqedwa kwezinhlelo zokuqeqesha lenyuke ngo-25%. Ochwepheshe abavela kwi-National Institute of Sports Science bathi: “Ukuqapha kwe-WBGT kushintshe ukuphepha kwezemidlalo kusuka ekwahluleleni okusekelwe kokuhlangenwe nakho kuya ekuqondisweni kwedatha, okuyintuthuko ebalulekile esimweni sesayensi sokuqeqeshwa kwezemidlalo eShayina.”
Njengoba isemester yasekwindla isondela, uMnyango Wezemfundo ucabangela ukufaka ukuqapha kwe-WBGT ku-“Regulations on School Physical Education Work”, ukuze lesi sinyathelo sokuzivikela sesayensi sizuze abadlali abasebasha abaningi. Kusukela emincintiswaneni yobungcweti kuya ezindaweni zokudlala zesikole, ukusungula izinto ezintsha kwezobuchwepheshe kwakha umugqa wokuzivikela oqinile wokuqeqeshwa okuphephile kwabadlali baseShayina.
