I-methylene blue nezemidlalo: indlela yokujonga imithetho yokulwa nedoping
I-methylene blue ayikhankanywanga ngegama layo kuLuhlu lwe-WADA lweZinto eziValiweyo luka-2026 lwesiNgesi, olujongwe ngomhla we-12 Septemba 2026. Ukukhangela elinye igama layo, i-methylthioninium, nako akufumananga nto ihambelanayo. Eso siphumo asiyomvume yakho yobuqu yokusebenzisa imveliso okanye inkqubo ethile. Ukuvumeleka kufuna ukuba kujongwe zonke izithako zemveliso, indlela yokuyinikwa, iindidi ezisebenzayo, nemithetho elawula imbaleki.
Ngoko ke, impendulo eluncedo inamacandelo amabini: oko kuthethwa yimithombo esemthethweni namhlanje, kunye nolwazi olusafunekayo ngemeko yakho. Ibango lomthengisi lokuba imveliso “ithobela i-WADA” alinakunika icandelo lesibini.
Qala ngeyeza kanye kunye nomdlalo
Ukukhangela amayeza kwi-Global DRO kufuna umdlalo kunye nelizwe ekuthengwe kulo, kuba uphawu lwemveliso lunokuba nezithako ezahlukeneyo kwiimarike ezahlukeneyo. Qinisekisa ukuba igama elipheleleyo lemveliso, amandla ayo, izithako ezisebenzayo, kunye nendlela yokuyinikwa ziyahambelana. Funda imiqathango ekwisiphumo ngokusetyenziswa ngexesha lokhuphiswano nangaphandle kwalo. Gcina isiphumo, kuquka umhla waso nenombolo yesalathiso xa zinikiwe.
Uvimbakazi uquka amayeza akumazwe athatha inxaxheba. Awuniki mvume yezongezelelo, kwaye imiqathango yawo ichaza ukuba kusenokusebenza izithintelo ezahlukileyo zombutho wezemidlalo okanye zesiganeko esikhulu. Ukuba iyeza alikho, buza umbutho ofanelekileyo wokulwa nedoping kunokuthatha ukungabikho kwesiphumo njengemvume. Iimbaleki ezithatha inxaxheba kwimidlalo engaphezu komnye kufuneka zijonge umdlalo ngamnye.
Thumela ifoto yeleyibhile kunye nombuzo ocacileyo. Umbuzo othi “Ndingayithatha i-methylene blue?” ushiya ngaphandle ulwazi olunokutshintsha impendulo. Umbuzo oluncedo ngakumbi uthi: “Ndikhuphisana kulo mdlalo phantsi kwalo mbutho. Le yimveliso, uluhlu lwezithako, ilizwe ekuthengwe kulo, indlela ecetywayo yokuyinikwa, kunye nokusetyenziswa kwezonyango okucetywayo. Yeyiphi imithetho neemfuno zokukhululwa kwisithintelo ezisebenzayo?”
Funda iindidi, hayi isalathiso esilandelelana ngokwealfabhethi kuphela
ULuhlu lwe-WADA luquka iindidi ezibanzi kunye nemizekelo engaziquki zonke izinto. Ukukhangela igama akunakukhupha zonke iindidi ezinokusebenza. Ngokunjalo, intengiso ethetha “nge-mitochondria” okanye “ngeoksijini” ayiqinisekisi ukuba into iwela phantsi kwezinto eziguqula imetabolism okanye iindlela ezivaliweyo zokuguqula igazi. Cacisa ukuhlelwa okungaqinisekanga nombutho onoxanduva wokulwa nedoping.
I-S0 ibhekisa kwizinto ezisebenza njengamayeza ezingenamvume yangoku karhulumente yokusetyenziswa ekunyangeni abantu nezingachazwanga kwenye indawo kuLuhlu. Ayiluvavanyo nje lokuba ibhotile ethengiswayo ineleyibhile yeyeza elifuna umyalelo kagqirha na. I-methylene blue ikhona njengeyeza elivunyiweyo labantu, inaliti ye-PROVAYBLUE yokunyanga i-methemoglobinemia efunyenweyo. Loo nto ayiqinisekisi ukufaneleka komnye umxube, isithako esongezelelweyo, okanye ukusetyenziswa okucetywayo.
Indlela ye-IV ifuna ukujongwa ngokwayo
Phantsi kwe-M2.2, ukufakwa kolwelo ngemithambo yegazi kunye neenaliti ezinikwa ngemithambo yegazi ezinesixa esipheleleyo esingaphezu kwe-100 mL kwisithuba seeyure eziyi-12 kuvaliwe ngawo onke amaxesha, ngaphandle kweemeko ezichaziweyo zonyango olusemthethweni esibhedlele, utyando, okanye uphando lwezonyango lokuxilonga. Inqaku langoku le-USADA elichaza i-IV lichaza ukuba oku kusebenza nakwizithako ezivumelekileyo. Isixa esipheleleyo siquka ukunikezelwa izihlandlo ezininzi; asisosixa esivumelekileyo esahlukileyo sengxowa nganye okanye inaliti nganye. Umda ubhekisa kumthamo wolwelo, hayi kwiimiligram ze-methylene blue, kwaye awusosindululo sonyango.
Izikhokelo ze-WADA ze-IV zoogqirha, inguqulelo 8.1, zahlula unyango esibhedlele kunyango kwigumbi eliqhelekileyo likagqirha, kwigumbi lasehotele, ekhaya, kwintente yezonyango yesiganeko, okanye kwikliniki ezimeleyo ye-IV. Ukufakwa kolwelo ngugqirha akukwenzi ngokuzenzekelayo ukuba kubekho ukukhululwa kwisithintelo. Ukuba into efakwa ngolwelo yona ivaliwe, ukukhululwa okunxulumene nendlela esetyenziswa esibhedlele akuyisusi imfuneko ye-TUE yaloo nto.
Kunyango olucwangcisiweyo, nika umbutho wokulwa nedoping iinkcukacha ezipheleleyo zenkqubo. Ugqirha kufuneka abhale uxilongo, izithako, umthamo opheleleyo wolwelo, amaxesha, indawo, nesizathu sonyango. Ingcaciso yethu ngeenaliti ze-methylene blue nemixube ye-IV ichaza ukuba kutheni ukufaneleka kokusetyenziswa ngenaliti nako kungumbuzo wezonyango owahlukileyo.
Kwimeko engxamisekileyo, fumana unyango oluyimfuneko kuqala. Yazisa umbutho onoxanduva emva koko uze ugcine amaxwebhu. Ukukhululwa ngenxa yokusetyenziswa kunyango, okanye i-TUE, okunokunikwa emva konyango kusenokufumaneka kwiimeko ezifanelekileyo; akunikezelwa ngokuzenzekelayo. Isikhokelo se-USADA se-TUE sichaza ukuvavanywa koxilongo, imfuneko yonyango, ezinye iindlela ezivumelekileyo, neemfuno ezisebenzayo zokufaneleka.
Ibhotile inokuzisa ingxaki eyahlukileyo
Imveliso equlethe i-methylene blue isenokuqulatha nezinye izithako ezisebenzayo. Isongezelelo sisenokuba nongcoliseko olungachazwanga. Isikhokelo se-UK Anti-Doping ngezongezelelo sichaza uxanduva olungqongqo: iimbaleki zinoxanduva lwezinto ezivaliweyo ezisemizimbeni yazo, kuquka nezingene zingaqondanga. Sikwachaza ukuba imibutho yokulwa nedoping ayizivumeli okanye izixhase iimveliso zezongezelelo.
Ukuvavanywa kwebhetshi kunokunciphisa umngcipheko wongcoliseko, kodwa akunakuqinisekisa ukuvumeleka. Ingxelo yobunyulu bekhemikhali ayiluvavanyo lokulwa nedoping ngokuzenzekelayo. Jonga ukuba yintoni evavanyiweyo kanye nokuba ibhetshi evavanyiweyo iyahambelana na nebhotile ethengiweyo. Isikhokelo sokufunda isatifikethi sohlalutyo lwe-methylene blue sichaza olo hlolo lwamaxwebhu.
Uluhlu lokuqinisekisa olunomhla
Imithombo esemthethweni ijongwe: 12 Septemba 2026. ULuhlu luka-2026 luqale ukusebenza ngomhla we-1 Januwari 2026. Phinda ujonge xa kutshintsha imithetho, imveliso, indlela yokuyinikwa, umdlalo, okanye isiganeko. Khuphela le theyibhile kwirekhodi yakho uze ugcwalise isithuba ngasinye ngesiphumo nobungqina.
| Ukujonga | Umthombo osemthethweni nenyathelo | Irekhodi yakho |
|---|---|---|

Ukukhululwa kwisithintelo | Landela inkqubo yegunya elifanelekileyo; isikhokelo se-UKAD sokukhangela, ukujonga nokufaka isicelo sibonisa indlela yokujonga ukuba kufuneka ufake isicelo na, nini, kwaye njani, usebenzisa ubungqina bezonyango. | Igunya elinoxanduva, imfuneko, isigqibo, imiqathango: ___ |
| 5. Ubungqina obugciniweyo | Gcina ileyibhile, isiphumo sokukhangela, amaxwebhu ezonyango, nembalelwano. Jonga negunya lakho ukuba isiganeko siyayamkela na i-TUE osele unayo. | Indawo yefayile, ukwamkelwa, umhla wokuphelelwa/lokuphinda kujongwe: ___ |
Umqolo ongasonjululwanga ngumbuzo omele uwuse kumbutho onoxanduva. Itheyibhile ibhala inkqubo yokuqinisekisa; ukuyigcwalisa akukokukhululwa kwisithintelo okanye imvume esemthethweni.
Ukuvumeleka, ukusebenza kwezemidlalo, nokuphazamiseka kovavanyo yimibuzo eyahlukileyo
Isiphumo sokujonga imithetho yokulwa nedoping asiqinisekisi ukuba i-methylene blue iphucula unyamezelo, amandla, okanye ukubuyela esimweni. Loo mabango afuna iziphumo ezifanelekileyo zokusebenza kwabantu kwezemidlalo, kunokuba kuthathwe isigqibo kwindlela esebenza ngayo kwiinkqubo zebhayokhemistri. Isikhokelo sobungqina bokuzilolonga nokubuyela esimweni sixoxa ngalo mbuzo wahlukileyo.
Ukuphazamiseka kwemilinganiselo yezonyango kwahlukile nako. Ileyibhile ye-PROVAYBLUE ibhala ukuba isixhobo sokulinganisa ioksijini egazini ngepulse sinokunika amanani angaphantsi kwawokwenene, nokuba kunokuphazamiseka uvavanyo lomchamo olusebenzisa izalathisi eziluhlaza okwesibhakabhaka, kuquka imicu yovavanyo ye-leukocyte esterase. Ezi zinto ziqatshelweyo aziqinisekisi okwenzekayo kuvavanyo oluthile lokulwa nedoping kwaye aziniki kukhululwa kulawulo lwedoping. Xelela abasebenzi bezonyango ngokuchanabeka kwakho ukuze bakwazi ukutolika imilinganiselo; jonga i-methylene blue nokuphazamiseka kovavanyo lwaselabhoratri.
Ukufaneleka kwezonyango kuhlala kusisigqibo esahlukileyo, kuquka ukusebenzisana namanye amayeza nemingcipheko enxulumene ne-G6PD echazwe kwisikhokelo sokhuseleko lwe-methylene blue. Nika ugqirha okunyangayo nombutho onoxanduva wokulwa nedoping ulwazi olufanayo noluchanekileyo ngemveliso nangokuchanabeka kwakho kuyo.
