Ama-treadmillziyimishini enemisebenzi eminingi evame ukutholakala ezindaweni zokuzivocavoca nasezindlini emhlabeni jikelele.Kuwucezu oludumile lwemishini yokuqina esetshenziselwa ukugijima, ukugijima, ukuhamba, ngisho nokukhuphuka.Nakuba sivame ukuthatha lo mshini kalula namuhla, bambalwa abantu abazi umlando walolu hlobo lwemishini yokuzivocavoca.Wake wazibuza ukuthi i-treadmill yasungulwa nini?Kulesi sihloko, sixoxa ngomlando othakazelisayo we-treadmill nokuthi uguquke kanjani ngokuhamba kwesikhathi.
Inguqulo yokuqala eyaziwayo ye-treadmill "i-treadwheel" noma "i-turnspit" eyasungulwa amaRoma ngekhulu lokuqala AD.Iwucezu lwemishini esetshenziselwa ukugaya okusanhlamvu, ukumpompa amanzi, kanye namandla emishini eyahlukene.I-treadwheel inesondo elikhulu elijikayo elixhunywe kwi-eksisi eqondile.Abantu noma izilwane zazinyathela isondo, futhi lapho liphenduka, i-asi yayinyakazisa eminye imishini.
Ngokushesha phambili ekhulwini le-19, futhi i-treadmill yashintsha yaba idivayisi yokujezisa esetshenziswa ohlelweni lwejele.Iziboshwa zazisebenza usuku lonke kuma-treadmill, ziphehla ugesi wemishini efana nokugaya ufulawa noma ukupompa amanzi.Ama-treadmill nawo ayesetshenziswa njengempoqo ezigebengwini, futhi isijeziso nokusebenza kwakubhekwa njengesihluku esingaphansi kwezinye izindlela zokujezisa.Lokhu kuhlukumeza kakhulu, futhi ngeshwa, akugcini nje eNgilandi.
Nokho, ngokushesha umbono we-treadmill waphinde washintsha, futhi waba umshini wokuqina odumile ekupheleni kwekhulu le-19.Yasungulwa nguWilliam Staub ngo-1968, i-treadmill yesimanje yashintsha ukugijima kwangaphakathi.Umshini we-Staub unebhande elixhunywe kunjini ehamba ngesivinini esimisiwe, elivumela umsebenzisi ukuthi ahambe noma agijime endaweni yakhe.UStaub wayekholelwa ukuthi ukusungulwa kwakhe kwakunamandla embonini yokufaneleka, futhi wayeqinisile.
Ngekhulu lama-21, ama-treadmill obuchwepheshe obuphezulu aphuma futhi asedumile ezindaweni zokuzivocavoca nasezindlini emhlabeni jikelele.Ama-treadmill esimanje afakwe izibonisi zedijithali eziqapha izinga lokushaya kwenhliziyo yomsebenzisi, ukulandelela ibanga, ubude besikhathi nesivinini.Ngaphezu kwalokho, ziza ngezinhlobonhlobo zomumo nosayizi futhi zinikeza izici ozenza ngokwezifiso njengokuhlehlisa nokwenqaba izilungiselelo.
Namuhla, ama-treadmill adumile phakathi kwabantu bayo yonke iminyaka namazinga okufaneleka.Ziyindlela ephephile futhi elula yokuzivocavoca endlini, enikeza abantu ithuba lokuqhubeka nohambo lwabo lokufaneleka ngaphandle kokukhathazeka ngezinto zangaphandle ezifana nezimo zezulu noma izithiyo zesikhathi.Ama-treadmill nawo alungile kulabo abakhetha ukuzivocavoca bodwa noma ngokuphepha kwekhaya labo.
Sengiphetha, ama-treadmill asehambe ibanga elide kusukela asungulwa.Kusukela ekusetshenzisweni kwakudala kokugaya ufulawa kuya ezintweni zokuzivivinya ezidumile ekhulwini lama-21, umlando we-treadmill uyajabulisa njengoba uhlaba umxhwele.Njengoba ubuchwepheshe buqhubeka nokuthuthuka, singacabanga nje ikusasa le-treadmill.Inye into eqinisekile;ama-treadmill alapha ukuze ahlale futhi azoqhubeka nokuba yisisekelo embonini yokufaneleka.
