Dumbbell ni ubwoko bwibikoresho bifasha guterura ibiro hamwe nimyitozo ngororamubiri, ikoreshwa mukubaka imyitozo yimitsi.Kuberako nta majwi iyo yitoza, yitwa dumbbell.
Dumbbells nibikoresho byoroshye bikoreshwa mugukomeza imitsi.Ibikoresho byingenzi byingenzi bikozwe mucyuma, bimwe bifite reberi.
Ikoreshwa mumahugurwa yimbaraga zimitsi, imyitozo yo guhuza imitsi.Ku barwayi bafite imbaraga nke zimitsi iterwa no kumugara, kubabara no kudakora igihe kirekire, fata amajwi hanyuma ukoreshe uburemere bwikimenyetso kugirango ukore imyitozo irwanya kurwanya imbaraga zimitsi.
Dumbbells itoza imitsi imwe;Niba uburemere bwiyongereye, guhuza imitsi myinshi birakenewe, kandi birashobora no gukoreshwa nkubwoko bwimikorere yibikorwa byimitsi.
Imfashanyo yo guterura ibiro hamwe nimyitozo ngororamubiri.Hariho ubwoko bubiri bwuburemere buhamye hamwe nuburemere bushobora guhinduka.Ibirangantego byerekana uburemere.Fata icyuma cy'ingurube, inkoni y'icyuma hagati, impande zombi z'umupira ukomeye uzengurutse, kuko nta jwi ryumvikana mugihe cy'imyitozo, ryitwa dumbbell.Uburemere bwa dumbbell yoroheje ni 6, 8, 12, na 16 pound (pound 1 = 0.4536 kg).Uburemere bwibintu biremereye ni 10, 15, 20, 25, 30 kg, nibindi.Kimwe na barbell yagabanutse, mumabuye magufi yicyuma kumpande zombi zuburemere bwurupapuro ruzengurutse, uburebure bwa cm 40 ~ 45 z'uburebure, imyitozo yo guterura cyangwa imyitozo ngororamubiri irashobora kongera cyangwa kugabanya ibiro.Akenshi ukora imyitozo ya dumbbell, irashobora gushimangira imbaraga zimitsi yibice bitandukanye byumubiri.
Birazwi neza ko isesengura ryimihindagurikire yimbaraga za centrifugal rigomba gukorwa mugihe ikizamini cyimyitozo ngororamubiri cyogukora icyogajuru.Imbaraga za centrifugal zirashobora gutuma ikintu cyumwimerere hamwe na misa ntoya ibona inshuro nyinshi imbaraga za kinetic kurenza uko bisanzwe mumwanya muto, kandi igakomeza kubyara inertia, bityo imbaraga zingufu ntizishobora gusuzugurwa.Inganda zikora ibikoresho bya fitness zagerageje gushakisha uburyo bwo gukoresha ubu bwoko bwingufu za kinetic ako kanya mugushushanya ibicuruzwa.Muri iyi nzira, havutse imbaraga za kinetic ingufu dumbbell yavutse.Bicamo ibyiyumvo biremereye bya dibbell gakondo kandi bituma imyitozo iremereye iruhuka.Ihuza imikorere iranga umupira wamaboko na dibbell kugirango itange imyitozo yingenzi yimitsi ningaruka zimyitozo yumubiri.
