Makina opondapo mapazindi makina ogwiritsidwa ntchito m'njira zosiyanasiyana omwe amapezeka kwambiri m'ma gym ndi m'nyumba padziko lonse lapansi. Ndi chida chodziwika bwino cholimbitsa thupi chomwe chimagwiritsidwa ntchito pothamanga, kuthamanga, kuyenda, komanso kukwera mapiri. Ngakhale kuti nthawi zambiri timaona makinawa ngati osavuta masiku ano, ndi anthu ochepa okha omwe amadziwa mbiri ya mtundu uwu wa zida zolimbitsa thupi. Kodi munayamba mwadzifunsapo kuti treadmill idapangidwa liti? M'nkhaniyi, tikambirana mbiri yosangalatsa ya treadmill ndi momwe yasinthira pakapita nthawi.

Mtundu wakale kwambiri wa treadmill wodziwika bwino ndi "treadwheel" kapena "turnspit" yomwe idapangidwa ndi Aroma m'zaka za zana loyamba AD. Ndi chipangizo chomwe chimagwiritsidwa ntchito popera tirigu, kupopera madzi, ndikugwiritsa ntchito makina osiyanasiyana. Treadwheel ili ndi gudumu lalikulu lozungulira lomwe limalumikizidwa ku mzere woyima. Anthu kapena nyama ankaponda pa gudumu, ndipo likazungulira, axle inkasuntha makina ena.

Posachedwa kufika m'zaka za m'ma 1800, makina opukutira matayala anasanduka chida cholangira chomwe chinkagwiritsidwa ntchito m'ndende. Akaidi ankagwira ntchito tsiku lonse pa makina opukutira matayala, kupanga magetsi a makina monga ufa wopera kapena kupopera madzi. Makina opukutira matayala ankagwiritsidwanso ntchito ngati ntchito yokakamiza kwa zigawenga, ndipo chilango ndi ntchito zinkaonedwa kuti sizowopsa kwambiri kuposa mitundu ina ya chilango. Uku ndi kuzunza kwambiri, ndipo mwatsoka, sikuti ku England kokha.

Komabe, posakhalitsa, malingaliro a treadmill anasinthanso, ndipo anakhala chida chodziwika bwino cholimbitsa thupi kumapeto kwa zaka za m'ma 1800. Treadmill yamakono, yomwe idapangidwa ndi William Staub mu 1968, inasintha kwambiri kuthamanga kwamkati. Makina a Staub ali ndi lamba wolumikizidwa ku injini yomwe imayenda pa liwiro lokhazikika, zomwe zimathandiza wogwiritsa ntchito kuyenda kapena kuthamanga pamalo ake. Staub ankakhulupirira kuti luso lake linali ndi kuthekera mumakampani olimbitsa thupi, ndipo anali wolondola.

M'zaka za m'ma 2000, makina opumira aukadaulo wapamwamba adatuluka ndipo akhala otchuka m'ma gym ndi m'nyumba padziko lonse lapansi. Makina opumira amakono ali ndi zowonetsera za digito zomwe zimayang'anira kugunda kwa mtima wa wogwiritsa ntchito, mtunda wa njanji, nthawi ndi liwiro. Kuphatikiza apo, amabwera m'mitundu ndi makulidwe osiyanasiyana ndipo amapereka zinthu zomwe zingasinthidwe monga kutsika ndi kutsika.

Masiku ano, makina opumira matayala ndi otchuka pakati pa anthu azaka zonse komanso olimba thupi. Ndi njira yotetezeka komanso yosavuta yochitira masewera olimbitsa thupi m'nyumba, zomwe zimapatsa anthu mwayi wopitiliza ulendo wawo wolimbitsa thupi popanda kuda nkhawa ndi zinthu zakunja monga nyengo kapena nthawi yochepa. Makina opumira matayala ndi abwinonso kwa iwo omwe amakonda kuchita masewera olimbitsa thupi okha kapena m'nyumba zawo.

Pomaliza, makina opukutira matayala apita patsogolo kwambiri kuyambira pomwe adakhazikitsidwa. Kuyambira kale pogaya ufa mpaka zida zodziwika bwino zochitira masewera olimbitsa thupi m'zaka za m'ma 2000, mbiri ya makina opukutira matayala ndi yosangalatsa komanso yosangalatsa. Pamene ukadaulo ukupitilira kupita patsogolo, tingangoganizira za tsogolo la makina opukutira matayala. Chinthu chimodzi ndi chotsimikizika; makina opukutira matayala atsala ndipo apitiliza kukhala chinthu chofunikira kwambiri pamakampani olimbitsa thupi.
