Sayansi ya kunyumba yogwiritsira ntchito makina opumira

1, kusiyana pakati pa treadmill ndi kuthamanga panja

Treadmill ndi mtundu wa zida zolimbitsa thupi zomwe zimatsanzira kuthamanga panja, kuyenda, kuthamanga ndi masewera ena. Maseŵera olimbitsa thupi ndi amodzi, makamaka kuphunzitsa minofu ya m'munsi mwa miyendo (ntchafu, m'chiuno, matako) ndi minofu yapakati, pomwe akukweza ntchito ya mtima ndi mapapo ndikuwonjezera mphamvu ya mitsempha ndi minyewa.

Popeza ndi chitsanzo cha kuthamanga panja, mwachibadwa n’chosiyana ndi kuthamanga panja.

Ubwino wothamanga panja ndi wakuti uli pafupi ndi chilengedwe, zomwe zingachepetse thupi ndi malingaliro ndikumasula kupsinjika kwa ntchito ya tsikulo. Nthawi yomweyo, chifukwa mikhalidwe ya pamsewu imasiyanasiyana, minofu yambiri imatha kusunthidwa kuti igwire nawo ntchito yolimbitsa thupi. Vuto lake ndilakuti imakhudzidwa kwambiri ndi nthawi ndi nyengo, zomwe zimapatsanso anthu ambiri chifukwa chokhala aulesi.

Ubwino wamakina opumira matayala Ndi yakuti sikuletsedwa ndi nyengo, nthawi, ndi malo, imatha kuwongolera liwiro ndi nthawi yochitira masewera olimbitsa thupi malinga ndi momwe zinthu zilili, ndipo imatha kuwerengera molondola kuchuluka kwa masewera olimbitsa thupi ake, komanso imatha kuonera sewero pamene ikuthamanga, ndipo mzungu watsopano amathanso kutsatira njirayo.

2. N’chifukwa chiyani muyenera kusankha treadmill?
Monga tonse tikudziwa, makina opumira, makina ozungulira, njinga zozungulira, makina opalasa, mitundu inayi ya zida zamagetsi zingatithandize kuchepetsa mafuta, koma zida zosiyanasiyana zochitira masewera olimbitsa thupi m'magulu osiyanasiyana a minofu, kwa magulu osiyanasiyana a anthu, timada nkhawa kwambiri ndi kutentha kwa mafuta sikufanana.

Mu moyo weniweni, kuchita masewera olimbitsa thupi apakati ndi otsika mphamvu kumathandiza kwambiri kuti munthu azitsatira nthawi yayitali, ndipo anthu ambiri amatha kuchita masewera olimbitsa thupi kwa mphindi zoposa 40, kuti apeze mphamvu yabwino yowotcha mafuta.

Ndipo kuchita masewera olimbitsa thupi mwamphamvu nthawi zambiri sikumachitika kwa mphindi zochepa, kotero tikasankha zida, tikulimbikitsidwa kusankha mphamvu yapakati ndi yotsika yomwe ingasunge mu zida zawo zabwino kwambiri zotentha mafuta pamtima.

Kuchokera ku deta ina, tingaone kuti kuyankha kwa kugunda kwa mtima kwa treadmill ndiko koonekeratu, chifukwa mukakhala wowongoka, magazi m'thupi amafunika kugonjetsa mphamvu yokoka kuti abwerere kumtima, kubwerera kwa mitsempha kumachepa, kutulutsa kwa sitiroko kumakhala kochepa, ndipo kugunda kwa mtima kuyenera kulipidwa powonjezera, zomwe zimafuna kutentha kwambiri.

Mwachidule, treadmill ndi yosavuta kuchita masewera olimbitsa thupi, yosavuta kulowa mu kugunda kwa mtima komwe kumayaka mafuta, mphamvu yochita masewera olimbitsa thupi ndi nthawi yomweyo, treadmill imadya ma calories ambiri.

Chifukwa chake, pa zotsatira za kuchepetsa thupi la chipangizocho: makina opukutira > makina ozungulira > njinga yozungulira > makina opalasa.

Komabe, ziyenera kudziwika kuti kugunda kwa mtima kumakhala kolimba kwambiri kungapangitse kuti zikhale zovuta kutsatira kwa nthawi yayitali, kotero treadmill si yoyenera anthu okalamba.
