Nalane eaLipapali tsa lipapali tsa Liolimpikie bonahatsa mekhoa e pharaletseng ea theknoloji ea lipapali, kaho le thepa. Mona ke tlhaloso e qaqileng ea ho iphetola ha bona:

Lipapali tsa Liolimpiki tse mathang cinder topolyurethane

Liolimpiki tsa Boholo-holo

- Lipina tsa Pele (hoo e ka bang ka 776 BC):Lipapali tsa pele tsa Liolimpiki tse neng li tšoaretsoe Olympia, Greece, li ne li e-na le ketsahalo e le ’ngoe e bitsoang lebelo la lipapali, e ka bang bolelele ba limithara tse 192. Pina e ne e le tsela e bonolo, e otlolohileng ea litšila.

Liolimpiki tsa Kajeno

- Liolimpiki tsa Athene tsa 1896:Lipapali tsa pele tsa Liolimpiki tsa sejoale-joale li ne li e-na le pina e mathang Lebaleng la Lipapali la Panathenaic, e leng pina e otlolohileng ea limithara tse 333.33 e entsoeng ka majoe le lehlabathe le pshatlehileng, e loketseng merabe e fapa-fapaneng ho akarelletsa le 100m, 400m, le sebaka se selelele.

Qalong ea lekholo la bo20 la lilemo

- Liolimpiki tsa London tsa 1908:Pina e neng e le White City Stadium e ne e le bolelele ba limithara tse 536.45, e kenyellelitse sebaka sa cinder, se neng se fana ka sebaka se tsitsitseng le se tšoarellang ho feta litšila. Sena se ile sa tšoaea qaleho ea tšebeliso ea lipina tsa cinder liatleletiki.

Bohareng ba lekholo la bo20 la lilemo

Lilemong tsa bo-1920-1950:Ho tloaeleha ha litekanyo tsa pina ho qalile, ka bolelele bo tloaelehileng haholo ho ba limithara tse 400, tse nang le li-cinder kapa letsopa. Litsela li ne li tšoauoa ho netefatsa toka tlholisanong.

- Liolimpiki tsa Melbourne tsa 1956:Pina ea Melbourne Cricket Ground e entsoe ka litene tse khubelu tse petelitsoeng le lefats'e, e leng sesupo sa liteko tsa nako eo ka lisebelisoa tse fapaneng ho ntlafatsa ts'ebetso.

Mohla oa Synthetic

- Liolimpiki tsa Mexico City tsa 1968:Ena e bile phetoho e kholo kaha pina e entsoe ka thepa ea maiketsetso (pina ea Tartan), e hlahisitsoeng ke 3M Company. Bokaholimo ba maiketsetso bo ne bo fana ka khoheli e betere, bo tšoarella nako e telele, 'me boemo ba leholimo bo khona ho mamella, e leng se ileng sa ntlafatsa litšoantšiso tsa baatlelete haholo.

Qetellong ea Lekholo la bo20 la lilemo

-1976 Liolimpiki tsa Montreal: Pina ena e ne e e-na le sebaka se ntlafalitsoeng sa maiketsetso, se ileng sa fetoha tekanyetso e ncha ea lipina tsa litsebi lefatšeng ka bophara. Mehla ena e bile le lintlafatso tse kholo moralong oa lipina, tse shebaneng le polokeho ea baatlelete le ts'ebetso.

Lipina Tsa Kajeno

- 1990s-Hona joale: Lipina tsa sejoale-joale tsa Liolimpiki li entsoe ka thepa ea maiketsetso e thehiloeng ho polyurethane. Libaka li etselitsoe ts'ebetso e nepahetseng, ka cushioning ho fokotsa tšusumetso ho manonyeletso a limathi. Lipina tsena li lekanngoe ho ba bolelele ba limithara tse 400, ka litselana tse robeli kapa tse robong, e 'ngoe le e 'ngoe e le bophara ba limithara tse 1.22.

- Liolimpiki tsa Beijing tsa 2008: Lebala la Lipapali la Naha, leo hape le tsejoang ka hore ke Sehlaha sa Nonyana, le na le pina e tsoetseng pele ea maiketsetso e etselitsoeng ho ntlafatsa ts'ebetso le ho fokotsa likotsi. Lipina tsena hangata li kenyelletsa theknoloji ho lekanya linako tsa baatlelete le litekanyetso tse ling ka nepo.

Tsoelo-pele ea Theknoloji

-Smart Tracks:Lintlafatso tsa morao-rao li kenyelletsa ho hokahana ha theknoloji e bohlale, e nang le li-sensor tse kenelletseng ho lekola metrics ea ts'ebetso joalo ka lebelo, linako tse arohaneng, le bolelele ba nako ea nnete. Litlhahiso tsena li thusa thupelong le tlhahlobong ea ts'ebetso.

Lintlafatso tsa Tikoloho le Moshoelella

- Lisebelisoa tsa Eco-friendly:Ho boetse ho tsepamisitsoe maikutlo mabapi le ho tšoarella, ka tšebeliso ea thepa e bolokang tikoloho le mekhoa ea kaho ho fokotsa tšusumetso ea tikoloho. Lisebelisoa tse ka sebelisoang hape le mekhoa e tsitsitseng ea tlhahiso e ntse e ata. Joalo ka pina ea ho matha ea rabara e entsoeng esale pele.
