Pamene Masewera a Commonwealth akuyamba, asayansi akuwulula ngati anthu adzathamanga 100m pansi pa masekondi 9.

Ichi ndi chimodzi mwazochitika zomwe zimayembekezeredwa mwachidwi pampikisano uliwonse wamasewera, ndipo tsopano kutentha kwa mamita 100 kwayambika pa Commonwealth Games ku. Birmingham.

Mpikisano wa amuna udzawona Jeremiah Azu wa Wales atengana ndi Ferdinand Omanyala waku Kenya komanso Ackeem Blake waku Jamaica pomwe waku Jamaica. Shelly-Ann Fraser-Pryce akadali wokondedwa kwambiri pa mpikisano wa akazi.

Amene ali ndi mbiri ya chochitikacho ndi Usain Boltyemwe adasewera masekondi 9.58 modabwitsa pa 2009 IAAF World Championships.

Ndipo ngakhale othamanga ena angapo amalizanso mpikisanowu pasanathe masekondi 10, palibe amene athyole chotchinga cha masekondi asanu ndi anayi.

Choncho, funso n’lakuti: Kodi munthu angathamangire mamita 100 mkati mwa masekondi asanu ndi anayi?

Ndi gawo loyamba lamwambowu pa Masewera a Commonwealth kuyambira lero, MailOnline idalankhula ndi asayansi kuti athandizire kuyankha funsoli – ndi malingaliro osiyanasiyana.

Omwe ali ndi mbiri pamwambowu ndi Usain Bolt, yemwe adasewera masekondi 9.58 pa mpikisano wadziko lonse wa IAAF wa 2009.

Chaka cha 1968 chisanafike, chizindikiro cha 10-sekondi chimaonedwa kuti ndi chotchinga pampikisano wamamita 100.

Koma Jim Hines adadabwitsa owonera padziko lonse lapansi pomwe adasewera masekondi 9.95 pa Masewera a Olimpiki a 1968 ku Mexico City.

Kuyambira nthawi imeneyo, mbiri yapadziko lonse yakhala ikudumphadumpha, ndipo ambiri mwa othamanga amuna apamwamba tsopano ali ndi mpikisano wachiwiri wa 10 pansi pa lamba wawo.

Koma kudumpha kuchokera ku mbiri ya Bolt ya 2009 ya masekondi 9.58 mpaka masekondi asanu ndi anayi sikutanthauza kanthu.

Malinga ndi a Polly McGuigan ndi Aki Salo, aphunzitsi a Sport Biomechanics ku yunivesite ya Bath, vuto lalikulu pakukwaniritsa mtundu wachiwiri wachisanu ndi chinayi ndi kuchuluka kwa mphamvu zomwe anthu angapange, komanso zomwe zimafunikira kuti akwaniritse izi.

Kuti apange masitepe ataliatali pafupipafupi, othamanga ayenera kupanga mphamvu yayikulu munthawi yochepa kwambiri – pafupifupi 4.5 kuchulukitsa kulemera kwa thupi lawo pafupifupi masekondi 0.1.

Kuti achite izi, othamanga ayenera kukhala ndi mwendo wouma kwambiri ndikuufulumizitsa pansi polumikizana ndi phazi, adatero Dr McGuigan ndi Pulofesa Salo m’nkhani ya. Kukambirana.

‘Kafukufuku waposachedwapa wasonyeza kuti ndi kusiyana kumeneku mu mphamvu zomwe zimapangidwira kumayambiriro kwa gawo lokhazikika (pambuyo pa kukhudzana ndi phazi) zomwe zimasiyanitsa othamanga othamanga kwambiri ndi omwe sali othamanga kwambiri,’ iwo anatero.

‘Kukhoza kukhalabe ndi chiwalo cholimba kumatsimikiziridwa ndi momwe mphamvu ya minofu ingapangidwire mu minofu ya mwendo.

Kodi nsapato za ‘Super-spike’ zitha kukhala yankho pakuswa chotchinga chachiwiri cha 9?

Kafukufuku wopangidwa ndi University of Massachusetts adafufuza zatsopano zamasewera, kuphatikiza thovu lopepuka, lolimba, komanso logwirizana ndi midsole, kusintha kwa geometry, komanso kulimba kwa nsapato kwautali wopindika.

Amafuna kupeza njira yowerengera phindu laukadaulo watsopano, koma adapeza zinthu zambiri zosokoneza zimayenera kuganiziridwa.

Gululo linanena kuti kuyenera kudikirira makampani angapo kuti apereke ukadaulowo ndipo kuti ugwiritsidwe ntchito kwambiri mutha kutsata zotsatira za mpikisano.

“Pamapeto pake, titha kungodalira kufananizira kosagwirizana ndi machitidwe amasewera asanachitike komanso pambuyo- kuyambitsidwa kwa ma spikes apamwamba, kapena, pamlingo wapayekha, kusintha kwamaphunziro a othamanga kapena nthawi ya mpikisano,” olemba adalemba.

‘M’zaka zingapo, titha kuyembekezera kuwunika momwe magwiridwe antchito akuyendera pazaka 20 zapamwamba komanso 50 zapamwamba zapachaka, zofanana ndi zomwe zikusindikizidwa pa nsapato zapamwamba za marathon.

“Ndizokopa kunena kuti mbiri yatsopano yapadziko lonse lapansi ndi luso la nsapato, koma machitidwe a nthawi yayitali, mwachitsanzo, Sydney McLaughlin ndi Karsten Warholm, sangathe kunyalanyazidwa,” olembawo adatero.

Zomwe zapezazo zasindikizidwa mu Kusindikiza koyamba kwa SportRxiv.

‘Izi nazonso ndi ntchito ya kukula kwa minofu, mitundu ya ulusi womwe umapanga minofu ndi kugwirizanitsa kogwirizana kwa minofu ya mwendo kuti ipititse patsogolo kugwiritsa ntchito njira zotanuka ndikukulitsa mphamvu kuchokera ku minofu.

‘Minofu yokhala ndi chiwerengero chachikulu cha ulusi waukulu, wothamanga wothamanga kwambiri ukhoza kupanga mphamvu zazikulu mofulumira kuposa minofu yomwe ili ndi gawo lochepa.’

Malinga ndi ofufuzawo, zinthu zophatikizika zidzafunika kuti zifike pomwe mphamvu zokwanira zitha kupangidwa mwachangu kuti zitheke kutalika kwa masitepe ndi ma frequency ofunikira pampikisano wachiwiri wachisanu ndi chinayi.

‘Kuphatikizika kwa majini ndi maphunziro kungafunike kupanga minofu ya bum, ntchafu ndi ng’ombe yamphongo yomwe imakhala yamphamvu pang’ono komanso yothamanga kuposa othamanga kwambiri omwe alipo tsopano,’ iwo anafotokoza.

Akatswiri a University of Bath akuwonetsa kuti mbiriyo idzayamba kutsika nthawi ina, ndipo zidzakhala zovuta kwambiri kuposa yemwe anali ndi mbiri yakale.

Komabe, akukhalabe ndi chiyembekezo chodzaphwanya chotchinga chachiwiri chachisanu ndi chinayi.

‘Ndizotetezeka kunena kuti wina athyola zotchinga zisanu ndi zinayi zachiwiri – osati m’moyo wathu wonse, koma zidzachitika tsiku lina,’ adamaliza.

Komabe, si onse amene ali ndi maganizo abwino.

Polankhula ndi MailOnline, Dr Sam Allen, Mphunzitsi wamkulu wa Biomechanics pa yunivesite ya Loughborough, adati akukayikira kuti mamita 100 adzatsirizidwa pasanathe masekondi asanu ndi anayi.

‘Kutengera kuchuluka kwa zomwe zikuchitika pano ndinganene ayi,’ adatero.

‘Koma mwachiwonekere chilichonse chitha kuchitika mu nthawi yokwanira, palibe kuwerengera zinthu zomwe sizikudziwika zomwe zikusinthiratu zigoli.’

Dr Allen akukhulupirira kuti kupita patsogolo kwaukadaulo kungathandize kulimbikitsa mwayi wophwanya chotchinga cha masekondi asanu ndi anayi.

“Mosakayikira nsapato ndi malo otsetsereka zitha kusintha nthawi yothamanga koma kuchuluka kwake kudzadalira kuchuluka kwa mabungwe olamulira omwe amachepetsa luso mderali,” adatero.

‘Zikuoneka kuti aletsa kale mapiko othamanga chifukwa zinkaoneka kuti apititsa patsogolo ntchito yawo mopambanitsa.’

Ma bums akulu amathandizira othamanga kuthamanga mwachangu: Large gluteus maximus imatha kulimbikitsa magwiridwe antchito mpaka 44 peresenti, kafukufuku akuwonetsa

Akatswiri ochokera ku yunivesite ya Loughborough adapeza kuti othamanga (achithunzi) okhala ndi gluteus maximus yaikulu - minofu yomwe imapanga pansi - imatha kuthamanga mpaka 44 peresenti mofulumira.
