Ithimba labacwaningi elivela eMnyangweni we-Biomechanics eNyuvesi yaseBayreuth lihlole amasoli ezicathulo ezigijimayo ezingaphezu kwe-100. Imiphumela yembula ukuthi ngaphezu kwengxenye eyodwa kwezintathu yamasoli ayeklanywe kabi endaweni yesithende, ngaleyo ndlela kube nomthelela engozini yokulimala kwabagijimi.
Ezemidlalo ziyingxenye yempilo enempilo futhi zisiza ekuvimbeleni izifo ezingamahlalakhona. Ukugijima kungenye yemisebenzi engokomzimba etuswe yiNhlangano Yezempilo Yomhlaba, futhi ijabulela ukuthandwa okukhulu ngenxa yokusebenziseka kwayo kalula: Akudingi izikhungo zemidlalo ezikhethekile noma imishini - ngaphandle kwezicathulo zokugijima. Kodwa-ke, izicathulo ezigijimayo kufanele zenzelwe ukuvimbela ukulimala kanye ne-syndromes engapheli yokusebenzisa ngokweqile. Izinga lokulimala phakathi kwabagijimi bezokungcebeleka, nokho, lingamaphesenti angama-45 ngonyaka. Ukugijima kufanele kube okunempilo, kodwa futhi kungabangela izinkinga zempilo. Izifundo ezifana nalezo eziqhutshwa abacwaningi baseBayreuth zisiza ukuthuthukisa ukuklama kwezicathulo ezigijima futhi ngaleyo ndlela kuvimbele ukulimala ngesikhathi semidlalo.
Izingxenye zesithende zezicathulo ezigijima zibaluleke kakhulu ekukhusheni. Izicathulo ezibekwe kahle zimunca amandla akhiqizwayo uma ushaya, ukuvimbela umlenze ukuthi ungamunce la mandla. Lokhu kuvimbela ukugcwala ngokweqile kwemisipha namalunga. Uma izinto zezingxenye zesithende zicindezela kancane kuphela, izicathulo zizizwa ziqinile ngenxa yokuntuleka kokunciphisa. Kodwa izinto ezithambile kakhulu nazo zingazizwa ziqinile lapho zigijima, njengoba ukucindezela okweqile kwempahla kubangela ukuba isithende sishaye phansi, futhi uyasizwa. Ngakho-ke kufanele kube nephuzu elilungile phakathi kwalokhu okubili okweqisayo lapho isithende sigoqeke kahle. "Izindinganiso zamanje zokuhlola ingxenye yesithende yezicathulo ze-sprint azilungile, njengoba zihlola izicathulo ngokumuncwa kwamandla kwama-joules amahlanu. Nokho, akuwona wonke umuntu ogijima ngendlela efanayo, ngakho akuwona wonke umuntu okhiqiza ama-joules amahlanu wamandla ngaso sonke isiteleka sesithende, "kusho uProf. Ngakho-ke ukholelwa ukuthi izindlela ezingcono ziyadingeka ezingasekelwe ezilinganisweni eziqinile.
Ngakho-ke, uFuss, kanye nabafundi abafundela ubudokotela u-Tizian Scharl no-Niko Nagengast, basungule uhlelo olusha lokuhlola lokulinganisa izakhiwo zezingxenye zesithende. Le ndlela ibala isilinganiso samandla amuncwa kumandla asetshenzisiwe futhi inquma lokho okubizwa ngokuthi i-shoulder point, lapho lesi silinganiso sifinyelela khona esiphezulu, okungukuthi lapho amandla amaningi emuncwa khona ngamandla amancane angenzeka. Lesi esiphezulu silungele ukumuncwa ukushaqeka ngenkathi usebenza. Besebenzisa imingcele yokulinganisa emine endaweni yehlombe, abacwaningi be-Bayreuth bahlole izicathulo ezigijimayo ezingu-112 ezivela kubakhiqizi abahlukene futhi bazihlukanisa zibe izigaba ezintathu: ezenziwe ngokweqile (i-cushioning encane kakhulu ngoba inzima kakhulu, okusho ukuthi kuzodingeka amandla amaningi kakhulu ukuze kutholakale ukugoqa okuphezulu), okwenziwe kahle (i-cushioning elungile), futhi ngenxa yokuthi i-unjiniyela ithambile kakhulu (iphansi kakhulu).
Besebenzisa indlela yabo entsha, abacwaningi bathola ukuthi amaphesenti angu-112 amamodeli ezicathulo angu-38 ahlolwe ayengaphezu-noma ayengathuthukisiwe. "Lezi ziphambeko zokuklama ngokusobala azihlosile kubakhiqizi, njengoba kungekho ndlela yokuhlola ephelele kuze kube manje. Kodwa-ke, lokhu kubonisa futhi ukuthi imihlahlandlela yokuklama nokwakhiwa kwezingxenye zesithende iyadingeka ukuze kuvinjelwe ukulimala, "kusho uFuss.
Ukwengeza, lolu cwaningo lunikeza izindlela zokuqala ze-3D-printed soles izicathulo lapho izingxenye zesithende zingashintshwa ngabanye abagijimi ngokuklama okulula nokuhlelekile.
Ucwaningo lwenziwe ngokubambisana neFraunhofer IPA - Applied Biomechanics Group kanye nomkhiqizi wezimpahla zezemidlalo iPuma.
