Imashini yo koga nigikoresho cyamahugurwa yigana amazi. Umukino wo mu nzu wahindutse siporo yabigize umwuga. Imashini zo koga mu nzu zizwi kandi nka ergometero (izwi kandi nka Ergo cyangwa ERGO mu bihugu by'amahanga), zikoreshwa mu gupima imbaraga zikoreshwa n'abakinnyi mu myitozo [1].

Imashini yo koga ifasha gushimangira imitsi yo mumaguru, ikibuno, ingingo zo hejuru, igituza, ninyuma. Buri nkoni izuzuza kwuzura no kwagura ingingo zo hejuru no hepfo ingingo, ikibuno ninda, ninyuma, bikavamo imyitozo yumubiri wuzuye umubiri wa aerobic. Imyitozo ya mashini yo koga ifasha cyane cyane abantu bafite ibinure byinshi mu rukenyerero, mu nda, no mu maboko yo hejuru.

Mugihe cyo koga, ugomba kwitondera guhuza ibikorwa byawe. Buri cyuma no kwaguka bigomba gukorerwa ahantu, nta guhagarara. Imitsi igira uruhare murugendo ntizaramburwa cyangwa ngo igabanuke niba amplitude ari nto cyane. Igereranya uburyo busanzwe bwo koga kandi ibereye siporo na siporo yo murugo, gukoresha imitsi yintoki, amaguru, ikibuno, nibindi bice, ikoresha neza imitsi irambuye, cyane cyane umugongo wo hepfo, ishobora kugabanya ibimenyetso byububabare bwumugongo ..
