Owesilisa oshesha ukwedlula bonke ake agijima imarathon: 2:02:57, evalwe nguDennis Kimetto waseKenya. Kwabesifazane, nguPaula Radcliffe, ogijime u-26.2 ngo-2: 15: 25. Ngeshwa, akekho umuntu wesifazane ozokwazi ukuvala lelo gebe lemizuzu eyishumi nantathu: Umehluko ubangelwa ukuthi amadoda anezintambo ezihlukene zomzimba (abanesilinganiso esiphezulu se-VO2-ivolumu ephezulu ye-oxygen engasetshenziswa umsubathi-ngokwesibonelo) kunathi, ngakho-ke bazohlala benaleyo nzuzo yesivinini. Kodwa, ungabi nomona kakhulu. Ucwaningo lukhombisa ukuthi thina mantombazane singakwazi ukuzihambela kangcono kunabafana.

Umphakathi ogijimayo usempikiswaneni eshubile yokuthi ngubani ozophula irekhodi likaKimetto ngokugijima umncintiswano ngaphansi kwamahora amabili (nokuthi lokho kuzokwenzeka nini). Kodwa, njengoba amadoda enenzuzo engalungile, abacwaningi bafuna ukuthola okulingana nomjaho wamahora amabili kwabesifazane. I-hypothesis yabo, eshicilelwe ocwaningweni lwakamuva ku Ijenali ye-Applied Physiology, ukuthi sekuvele kwenziwa-ukuthi u-2:15:25 ka-Radcliffe unzima kumuntu wesifazane njengoba ukugijima u-26.2 ngo-2:02 kungokowesilisa.

Kunezici ezintathu ezibikezela ukusebenza kwe-marathon: ukusetshenziswa okukhulu kwe-oxygen, umkhawulo we-lactate, kanye nomnotho osebenzayo, kusho umlobi ocwaningayo uSandra Hunter, Ph.D. Uyachaza ukuthi lezi zinto ezintathu uzithola kumuntu oyedwa, ”kuchaza yena. URadcliffe ungomunye walezo zinto ezingavamile, okuchaza ukuthi kungani eyi-anamoly uma kukhulunywa ngemijaho engama-26.2-mile. Ngokwazi lokho, abacwaningi bathathe izikhathi zakhe zokuqopha umncintiswano wezibalo zomhlaba bathola ukuthi kunomehluko we-12 kuye ku-13 wamaphesenti umehluko ocansini ngezikhathi zemarathon. Lokho kungasho ukuthi umjaho kaRadcliffe ka-2: 15: 25 ulingana nomjaho wamahora amabili wendoda.

URadcliffe uyisisekelo samandla abesifazane, ngakho-ke mvumele akugqugquzele ukuthi ukhulise inqubo yakho yokugijima! Thola ukushesha ngalezi Zeluleko Ezi-5 Zokusebenzisa Ukwehlukaniswa Okungekho Emiphumeleni Emihle futhi uthole ukuthi ungaSebenzisa Kanjani Ngokushesha, Ngokude, Ngokuqina, nangokuNgalimali. Noma (sikubophele!) Bhalisela uhhafu wakho wokuqala noma imarathon ephelele.
