Imashini yo gukaraba ni igikoresho cy’imyitozo cyigana gukaraba mu mazi. Gukaraba mu nzu byahindutse siporo y’umwuga. Imashini zo gukaraba mu nzu zizwi kandi nka ergometers (zizwi kandi nka Ergo cyangwa ERGO mu mahanga), zikoreshwa mu gupima imbaraga abakinnyi bakoresha mu gihe cy’imyitozo [1].

Imashini yo gukaraba ifasha gukomeza imitsi yo mu maguru, mu rukenyerero, mu maguru yo hejuru, mu gituza no mu mugongo. Buri gukaraba kuzuza ipfundo ryuzuye no kwagura amaguru yo hejuru n'ayo hasi, mu rukenyerero no mu nda, no mu mugongo, bigatuma imitsi yose ikora imyitozo ngororamubiri. Imyitozo yo gukaraba ifitiye akamaro cyane abantu bafite ibinure byinshi mu rukenyerero, mu nda no mu maboko yo hejuru.

Mu gihe urimo gukaraba, ugomba kwita ku buryo imigendere yawe ihora imeze. Buri gukaraba no kongerera imbaraga bigomba gukorwa ahantu hamwe, nta guhagarara. Imitsi ikora muri iyo mikorere ntizaramba cyangwa ngo igabanuke neza niba uburebure bwayo ari buto cyane. Yigana uburyo busanzwe bwo gukaraba kandi ikwiriye siporo yo mu rugo no mu ngo, ikora siporo y'imitsi y'amaboko, amaguru, ikibuno, n'ibindi bice, ikora siporo yo kunanura imitsi, cyane cyane umugongo wo hasi, ishobora kugabanya ububabare bw'umugongo.
