Kubadwa kwa treadmill

Ma treadmill ndi zida zolimbitsa thupi nthawi zonse zanyumba ndi malo ochitira masewera olimbitsa thupi, koma mumadziwa?Kugwiritsiridwa ntchito koyambirira kwa treadmill kwenikweni kunali chipangizo chozunzirapo akaidi, chomwe chinapangidwa ndi British.

Nthaŵi imabwerera kuchiyambi cha zaka za zana la 19, pamene Kusintha kwa Mafakitale kunayamba.Panthaŵi imodzimodziyo, chiŵerengero cha umbanda m’chitaganya cha Britain chinalibe chokwera.Momwe mungachitire?Njira yosavuta komanso yolunjika ndiyo kugamula mkaidi chigamulo cholemera.

Ngakhale kuti upandu udakali wokwera, akaidi ochulukirachulukira akulowetsedwa m’ndende, ndipo akaidi ayenera kuyang’aniridwa akalowa m’ndende.Koma bwanji kuyang'anira akaidi ambiri?Ndiponsotu, alonda andende amene amayang’anira akaidi ndi ochepa.Kumbali ina, boma liyenera kudyetsa akaidi, kuwapatsa chakudya, zakumwa, ndi kugona.Kumbali ina, afunikanso kusamalira ndi kusamalira zida za m’ndende.Bomazimandivuta kuthetsa.

Akaidiwo atadya ndi kumwa mokwanila, anali okhutila ndipo analibe potulukila, moti anadikila akaidi ena ndi nkhonya ndi mapazi.Alonda a ndende nawonso akugwira ntchito yosamalira minga imeneyi.Ngati amasulidwa, akhoza kuvulaza akaidi ena;ngati alimba, adzatopa ndi kuchita mantha.Choncho, kwa boma, mbali imodzi, liyenera kuchepetsa umbanda, ndipo kumbali ina, liyenera kuwononga mphamvu za akaidi kuti asakhale ndi mphamvu zowonjezera zomenyana.

Njira yachikhalidwe ndi yakuti ndende imakonza anthu kuti azigwira ntchito, motero amadya mphamvu zawo zakuthupi.Komabe, mu 1818, mwamuna wina dzina lake William Kubitt anapanga chipangizo chozunzirako anthu chotchedwa treadmill, chimene chinamasuliridwa m’Chitchaina kuti “treadmill”.Ndipotu “chopondaponda” chinapangidwa kalekale, koma si munthu amene amachita masewera olimbitsa thupi, koma kavalo.Cholinga cha izi ndi kugwiritsa ntchito mphamvu ya kavalo popera zinthu zosiyanasiyana.

Pamaziko a choyambirira, William Cooper analowa m'malo mwa akavalo ozizira ndi achifwamba omwe adalakwitsa kuti alange olakwa, ndipo panthawi imodzimodziyo adapeza zotsatira za zipangizo zopera, zomwe tinganene kuti kupha mbalame ziwiri ndi mwala umodzi.Mndendeyo itagwiritsa ntchito chida chozunzirako anthu, chinapezeka kuti n’chothandiza kwambiri.Akaidi amathamanga pa izo kwa maola osachepera 6 patsiku kukankhira mawilo kupopa madzi kapena kuponya.Kumbali ina, akaidi amalangidwa, kumbali ina, ndende imathanso kupeza phindu lachuma, lomwe ndi lalikulu kwambiri.Akaidi omwe atopa mphamvu zawo zakuthupi alibenso mphamvu zochitira zinthu.Ataona chozizwitsa chimenechi, maiko ena ayambitsa “matreadmills” a ku Britain.

Koma pambuyo pake, akaidiwo anali kuzunzidwa tsiku lililonse, zinali zotopetsa komanso zosasangalatsa, zinali bwino kugwira ntchito ndikuwuzira mpweya.Kuphatikiza apo, achifwamba ena amatopa kwambiri ndipo amavulala pambuyo pake.Pofika nthawi ya nthunzi, "treadmill" yakhala ikufanana ndi kubwerera m'mbuyo.Choncho, m’chaka cha 1898, boma la Britain linalengeza kuti lidzaletsa kugwiritsa ntchito “makina opondaponda” pozunza akaidi.

A British adasiya "treadmill" kuti alange akaidi, koma sankayembekezera kuti anthu a ku America odziwa bwino adzalembetsa ngati zida zamasewera.Mu 1922, makina oyamba olimbitsa thupi adayikidwa pamsika.Mpaka lero, ma treadmill asanduka chida champhamvu chapakhomo cha amuna ndi akazi olimba.
