I-Discus throw wumdlalo wakudala osadume kakhulu nanamuhla kumicimbi ye-track nenkundla. Ukukhetha i-discus efanele kuyisinyathelo esibalulekile kubasubathi abahlose ukwenza kahle emicimbini yokuncintisana. Nakuba i-discus iyithuluzi elilula kakhulu, abasubathi kusadingeka bacabangele izici ezifana nesisindo, impahla, nobukhulu.
Lo mhlahlandlela uzofaka ukuthi yiziphi izinhlobo ze-discus ezidume kakhulu, kanye nezinga lekhono nemigomo efanelana kangcono nenye ngayinye. Qhubeka ufunda ukuze ufunde kabanzi mayelana ne-discus nokuthi abathengi bafuna ini ngaphakathi kwemakethe.

Isiphetho
Iyini i-discus?
I-discus yinto eyisiyingi, eyisicaba ejikijelwa kumicimbi yethrekhi nenkundla. Ingenziwa ngezinto ezahlukene, njengokhuni noma insimbi, futhi inesisindo nobukhulu obuhlukahlukene kuye ngokuthi umsubathi oyisebenzisayo.
Ngesikhathi sokuphonswa kwe-discus, abasubathi bazothuthukisa umfutho ngokuzulazula kuyindilinga eshiwo ngaphambi kokwethula i-discus ngangokunokwenzeka. Kungumdlalo oyingqayizivele ohlanganisa ukunemba, amandla, kanye namasu, ngakho ukukhetha i-discus elungile kubaluleke kakhulu kumdlali.
Ingabe i-discus idumile?
Njengeminye ithrekhi nemicimbi yasensimini njenge ukubeka futhi umkhonto, i-discus ikhula kuphela ekudumeni phakathi kwabathengi. Lokhu kuncike ezintweni ezimbalwa, ezifana nethrekhi nenkundla eboniswa kakhulu ezinkundleni zokusakaza, kanye nokuba khona okujwayelekile kwama-Olympics, abukwa emhlabeni wonke.
Ngokwezikhangiso ze-Google, "i-discus" inevolumu yokusesha yanyanga zonke engu-201,000. Uma kuqhathaniswa neminye imidlalo ye-track and field, i-discus igcina izinga lokusesha elizinzile unyaka wonke, ngo-January, July, no-August kuphela obona ukwehla kancane kokusesha, kuze kufike ku-165,00 ngenyanga. Lezi zibalo zibonisa ukuthi i-discus idume kangakanani nokuthi iguquguquka kanjani njengomncintiswano wethrekhi nomkhakha.
Inani lemakethe yomhlaba wonke lemishini yethrekhi neyenkundla
Ukuduma kwemicimbi yethrekhi neyenkundla kukhule kakhulu kule minyaka eyishumi edlule. Intuthuko entsha kwezobuchwepheshe kanye nokushintsha okuthandwa ngamakhasimende kuphoqe abadlali bemakethe ukuthi bazivumelanise ngokushesha futhi bathole izixazululo zokukhula okuzinzile. Imakethe ibona ukwanda okuqhubekayo kwenani lokuthengiswa kwe-inthanethi, okuvumela abathengi ukuthi bathole ukufinyelela kokulandela umkhondo kanye nemishini yasendle ngesikhathi esifanele.
Ngo-2031, imakethe yemishini yethrekhi neyensimu kulindeleke ukuthi ibe ilinganiselwa ku-USD 161.67 billion. Lokhu ukukhuphuka okusheshayo kusuka ku-USD 101 billion ngo-2023. Izinga lokukhula elihlanganisiwe lonyaka (CAGR) phakathi kuka-2024 no-2031 kulindeleke ukuthi lihlale ku-6.69%.
Izici ezibalulekile ze-discus
I-discus iwucezu olulula lwe-track kanye nempahla yasensimini ongayisebenzisa, kodwa kuthatha isikhathi esiningi nekhono ukuze uphumelele indlela yokuphonsa. Kunezici ezimbalwa ezibalulekile abasubathi okudingeka bazicabangele lapho bekhetha i-discus efanele, njengoba kungezona zonke izingxoxo eziklanywe ngendlela efanayo.
Material
Enye yezinto ezinkulu okufanele zicatshangelwe lapho ukhetha i-discus yindaba. Ingadlala indima ebalulekile ekusebenzeni komsubathi, futhi impahla ngayinye inezici zayo.
Izingxoxo ezihlanganisiwe zenziwe ngezinto ezifana ne-carbon fibre noma i-fiberglass futhi zinikeza abasubathi inhlanganisela enhle yezakhiwo namandla angasindi. Zibhekwa njengezingxoxo ezisebenza kahle kakhulu futhi zenzelwe ukuzuza izici zendiza ezifanele, zizenze zifanelekele imiqhudelwano.
Izingxoxo zokhuni angasindi kakhulu futhi ajwayele ukusetshenziselwa ukuqeqeshwa lapho aqalayo njengoba kulula ukuwasebenzisa futhi athengeka kakhulu.
Ekugcineni, izingxoxo zensimbi ahlala isikhathi eside kunezingxoxo ezihlanganisiwe nezokhuni, ezenziwe ngethusi noma ngensimbi. Insimbi iyinto ekhethwayo yabasubathi abaphakathi nabasezingeni eliphezulu abadinga ukulondoloza ukusebenza okungaguquki.
Impahla ngayinye inikeza izimbangi okuthile okuhlukile, okuzoba nomthelela oqondile ebangeni nasekuzinzeni kwendiza. Abasubathi bazokhetha i-discus elungele bona ngokusekelwe ezingeni labo lamakhono.
Usayizi nesisindo
Ukuqinisekisa ukuncintisana okulungile, ubukhulu nesisindo sezingxoxo kumiswa ngokuya ngobulili neminyaka yomdlali. I-discus esindayo noma enkulu kakhulu kumsubathi ingaphazamisa kakhulu indlela yabo futhi iholele ekulimaleni. Ukuze ukwandise amandla okusebenza, ukukhetha usayizi ofanele nesisindo kubalulekile.
Emiqhudelwaneni yabesilisa, i-discus inesisindo esingamakhilogremu ama-2 futhi inobubanzi obungamasentimitha angama-22. Kwabesifazane abaphonsa i-discus, isisindo siyehla size sibe yikhilogremu engu-1 futhi singamasentimitha angu-18 ububanzi. Abasubathi abasebancane bazoba nesisindo se-discus esifinyelela ku-0.75 kilogram kuya ngesigaba sabo seminyaka.
Iphesenti lesisindo se-Rim
Ubukhulu obuphelele nesisindo se-discus kubaluleke kakhulu, kodwa iphesenti lesisindo serimu libaluleke kakhulu ukubhekwa. Lokhu kubhekisela esisindweni sesisindo se-discus esigxiliswe ku rimu yangaphandle, enomthelela oqondile ekuzinzeni nezici zendiza.
Ukuba nerimu enephesenti lesisindo esiphezulu, phakathi kuka-70% no-85%, kuzothuthukisa ukuzinza kwe-aerodynamic futhi kuvumele i-discus ukuthi ihambe iye phambili ngenxa yokuthi isisindo esiningi sisabalaliswa ngasemaphethelweni. Lolu hlobo lwe-discus ludinga izinga eliphezulu lamandla nekhono lokuphonsa ngempumelelo njengoba kuyinselele kakhulu ukuyilawula.
Izingxoxo ezinephesenti lesisindo esingaphansi kuka-70% kulula ukuziphonsa futhi zifaneleka kakhulu kwabaqalayo noma abasubathi abasebasha. Bathethelela kakhulu uma indlela yokusebenza ingaphelele, okubenza balungele ukuqeqeshwa. Njengoba abajikijeli be-discus beqhubeka, ekugcineni bazoshintshela ku-discus enesisindo serimu esiphezulu.
Izinga lomakhono
Esinye sezici ezinkulu lapho ukhetha i-discus efanele izinga lekhono lomsubathi. Akuzona zonke izingxoxo ezakhelwe injongo efanayo, ngakho-ke abathengi kudingeka baziswe ukuthi ukukhetha okungalungile kungaba nomthelela ongemuhle kanjani ekusebenzeni kwabo.
Abasaqalayo kufanele baqale ngephesenti eliphansi lesisindo serimu ngenkathi besafunda amasu ayisisekelo. Lokhu kubavumela ukuthi balawule kangcono i-discus futhi basebenze ngefomu yabo iyonke ngenkathi futhi begxile ekwakheni amandla. Ukuqeqeshwa ngalolu hlobo lwe-discus kuvumela umsubathi ukuthi asebenze kumakhenika afanele futhi akhe ukuzethemba ngaphambi kokudlulela ku-discus esindayo. Ngokuvamile bazosebenzisa izingxoxo ezihlanganisiwe zokhuni noma eziphansi ukuze baqale ngazo.
Abasubathi abathuthuke kakhulu bazosebenzisa amaphesenti aphezulu esisindo serimu, edizayinelwe ukusebenza okungcono kwe-aerodynamic kanye nebanga elikhulu. I-discus izokwenziwa ngezinto ezisezingeni eliphezulu njengensimbi noma izinhlanganisela ezithuthukisiwe ukuze ziqine kanye nezinjongo zokusebenza. Lezi zingxoxo zidinga amandla engeziwe nokunemba kokuphonswa, ngakho zifanele kuphela abasubathi abasebenza ukulungisa kahle ukusebenza kwabo futhi abaqhudelana emiqhudelwaneni yezinga eliphezulu.
Isiphetho
Lapho bekhetha i-discus efanele yokuqeqeshwa nemincintiswano, abasubathi bazobheka izici ezifana nempahla, isisindo nosayizi, iphesenti lesisindo serimu, namazinga abo amakhono. Njengemicimbi eminingi yethrekhi neyenkundla, i-discus kulindeleke ukuthi ikhule ekudumeni eminyakeni embalwa ezayo, okusho ukuthi imboni izodinga ukubheka ukuhlanganisa ubuchwepheshe obusha ezingxoxweni zakamuva.
