Zvigayo zveTreadmillmichina inoshandiswa zvakasiyana-siyana inowanikwa munzvimbo dzekurovedza muviri nedzimba pasi rose. Ichi chishandiso chinozivikanwa chekusimbisa muviri chinoshandiswa pakumhanya, kumhanya, kufamba, uye kunyange kukwira makomo. Kunyange zvazvo tichiwanzotora muchina uyu sewechokwadi nhasi, vanhu vashoma vanoziva nhoroondo yemhando iyi yemidziyo yekurovedza muviri. Wakambozvibvunza here kuti treadmill yakagadzirwa riini? Muchinyorwa chino, tinokurukura nhoroondo inonakidza yetreadmill uye kuti yakashanduka sei nekufamba kwenguva.
Shanduro yekutanga inozivikanwa yetreadmill inonzi "treadwheel" kana kuti "turnspit" yakagadzirwa nevaRoma muzana remakore rekutanga AD. Ichi chishandiso chinoshandiswa kukuya zviyo, kupomba mvura, uye kupa simba michina yakasiyana-siyana. Treadwheel ine vhiri guru rinotenderera rakabatana ne vertical axis. Vanhu kana mhuka vaitsika vhiri, uye paraitenderera, ekseli yaifambisa mimwe michina.
Kusvika muzana remakore rechi19, treadmill yakashanduka kuita chirango chaishandiswa mumajeri. Vasungwa vaishanda zuva rese patreadmill, vachigadzira magetsi emichina yakaita seyekukuya hupfu kana kupomba mvura. Zvigayo zvematreadmill zvaishandiswawo sebasa rekumanikidzwa kumatsotsi, uye chirango nebasa zvaionekwa sezvisina hutsinye kupfuura mamwe marudzi echirango. Uku kutambudzwa kwakanyanya, uye zvinosuwisa kuti, hazvingogumiri kuEngland chete.
Zvisinei, munguva pfupi, maonero emutambo wetreadmill akachinja zvakare, uye wakava muchina wekusimbisa muviri wakakurumbira pakupera kwezana remakore rechi19. Wakatangwa naWilliam Staub muna 1968, mutambo wetreadmill wemazuva ano wakachinja kumhanya kwemukati. Muchina waStaub une bhandi rakabatana nemota inofamba nekumhanya kwakatarwa, zvichibvumira mushandisi kufamba kana kumhanya panzvimbo. Staub aitenda kuti chigadzirwa chake chaive nekwaniso muindasitiri yehutano, uye aive akarurama.
Muzana remakore rechi21, matreadmill emhando yepamusoro akabuda uye ave akakurumbira mumitambo yekurovedza muviri nedzimba pasi rose. Matreadmill emazuva ano ane madhiraivha edhijitari anotarisa kurova kwemoyo wemushandisi, daro remunzira, nguva uye kumhanya. Uyezve, anouya mumhando dzakasiyana-siyana uye saizi uye ane maficha anogadziriswa akadai sekutsvedza nekudzika.
Nhasi uno, matreadmill anonyanya kufarirwa nevanhu vemazera ese uye vane hutano hwakanaka. Inzira yakachengeteka uye iri nyore yekurovedza muviri mumba, ichipa vanhu mukana wekuenderera mberi nerwendo rwavo rwekurovedza muviri vasina kunetseka nezvezvinhu zvekunze zvakaita semamiriro ekunze kana nguva shoma. Matreadmill akanakirawo avo vanoda kurovedza muviri vari vega kana vari mudzimba dzavo dzakachengeteka.
Mukupedzisa, matreadmill afambira mberi zvikuru kubva paakatanga. Kubva pakushandiswa kwekare kwekukuya hupfu kusvika kumidziyo yekurovedza muviri yakakurumbira muzana remakore rechi21, nhoroondo yetreadmill inonakidza sezvairi. Sezvo tekinoroji iri kuramba ichifambira mberi, tinogona kungofungidzira ramangwana retreadmill. Chinhu chimwe chete ndechechokwadi; matreadmill acharamba aripo uye acharamba ari chinhu chikuru muindasitiri yekurovedza muviri.
