IiTreadmillsziimatshini ezinokusetyenziswa ngeendlela ezahlukeneyo ezifumaneka rhoqo kwiindawo zokuzivocavoca nasemakhaya kwihlabathi liphela. Sisixhobo esidumileyo sokuzivocavoca esisetyenziselwa ukubaleka, ukubaleka, ukuhamba, kwanokunyuka. Nangona sihlala siwuthatha lula lo matshini namhlanje, bambalwa abantu abaziyo imbali yolu hlobo lwezixhobo zokuzilolonga. Ngaba wakha wazibuza ukuba i-treadmill yasungulwa nini? Kweli nqaku, sixoxa ngembali enomdla ye-treadmill kunye nendlela eye yatshintsha ngayo ngokuhamba kwexesha.
Uhlobo lokuqala lwe-treadmill olwaziwayo yi-"treadwheel" okanye "turnspit" eyasungulwa ngamaRoma kwinkulungwane yoku-1 AD. Sisixhobo esisetyenziselwa ukugaya iinkozo, ukupompa amanzi, kunye nokunika amandla oomatshini abahlukeneyo. I-treadwheel inevili elikhulu elijikelezayo eliqhotyoshelwe kwi-axis ethe nkqo. Abantu okanye izilwanyana babenyathela ivili, kwaye xa lijika, i-axle yayishukumisa ezinye iimatshini.
Ukuya phambili kwinkulungwane ye-19, kwaye i-treadmill yaguquka yaba sisixhobo sokohlwaya esisetyenziswa kwinkqubo yentolongo. Amabanjwa ayesebenza imini yonke kwii-treadmill, evelisa umbane kwiimatshini ezifana nomgubo wokusila okanye ukupompa amanzi. Ii-treadmill zazisetyenziswa njengomsebenzi onyanzeliswayo kwizigebenga, kwaye isohlwayo kunye nomsebenzi wawuthathwa njengongenabundlongondlongo kunezinye iintlobo zokohlwaya. Oku kukubandezeleka kakhulu, kwaye ngelishwa, akupheleli eNgilane kuphela.
Nangona kunjalo, kungekudala, indlela abantu abacinga ngayo nge-treadmill yatshintsha kwakhona, yaza yaba sisixhobo esidumileyo sokuzilolonga ekupheleni kwenkulungwane ye-19. Yasungulwa nguWilliam Staub ngo-1968, i-treadmill yanamhlanje yatshintsha indlela yokubaleka ngaphakathi. Umatshini kaStaub unebhanti eqhagamshelwe kwinjini ehamba ngesantya esimiselweyo, evumela umsebenzisi ukuba ahambe okanye abaleke endaweni yakhe. UStaub wayekholelwa ukuba le nto ayenzileyo inokuba negalelo kwishishini lokuzilolonga, kwaye wayechanekile.
Kwinkulungwane yama-21, ii-treadmill zobuchwepheshe obuphezulu zaphuma kwaye ziye zathandwa kwiindawo zokuzivocavoca nakumakhaya kwihlabathi liphela. Ii-treadmill zanamhlanje zixhotyiswe ngemiboniso yedijithali ejonga izinga lokubetha kwentliziyo yomsebenzisi, umgama womkhondo, ubude kunye nesantya. Ukongeza, ziza ngeemilo ezahlukeneyo kunye nobukhulu kwaye zibonelela ngeempawu ezinokwenziwa ngokwezifiso ezifana nokuseta ukuthambeka kunye nokwehla.
Namhlanje, ii-treadmill zithandwa ngabantu bayo yonke iminyaka kunye namanqanaba okuqina komzimba. Ziyindlela ekhuselekileyo nelula yokuzilolonga ngaphakathi, zinika abantu ithuba lokuqhubeka nohambo lwabo lokuqina komzimba ngaphandle kokukhathazeka ngezinto zangaphandle ezifana neemeko zemozulu okanye imida yexesha. Ii-treadmill zikwalungile kwabo bakhetha ukuzilolonga bodwa okanye kukhuseleko lwamakhaya abo.
Ukuqukumbela, ii-treadmill zihambe indlela ende ukususela ekuqaleni kwazo. Ukususela ekusetyenzisweni kwakudala komgubo wokusila ukuya kwizixhobo zokuzilolonga ezidumileyo kwinkulungwane yama-21, imbali ye-treadmill inomdla kwaye inomdla. Njengoko ubuchwepheshe buqhubeka buhambela phambili, sinokuyithelekelela ikamva le-treadmill. Into enye eqinisekileyo; ii-treadmill zilapha kwaye ziya kuqhubeka zibalulekile kushishino lomzimba.
