Maphunziro a Mphamvu ya Minofu ayenera kukhala gawo lofunikira kwambiri pakukonzanso.Mphamvu zimagwirizana mwachindunji ndi ntchito, zomwe zimatha kusinthidwa popanda zotsatira zoyipa kudzera muzolimbitsa thupi zokonzekera.Kulimbitsa mphamvu kwa minofu ya sitiroko sikungowonjezera mphamvu zophulika za minofu komanso kuphunzitsa kupirira.Cholinga cha maphunziro a mphamvu ya minofu ndikuonetsetsa kuti gulu la minofu kapena minofu liri ndi mphamvu zokwanira, mphamvu, ndi zowonjezereka kuti zikwaniritse ntchito yomwe ikufunidwa.
Mitundu iwiri ya minofu:
※ Kusagwirizana
※ Malleability
Kudumpha kwa minofu:
1. Kutsika kwa Isometric:
Pamene minofu imagwirizanitsa, mtunda pakati pa chiyambi ndi mapeto sasintha.
2. Kudumpha kwa isotonic:
Eccentric contraction: Pamene minofu imagwira ntchito, mtunda pakati pa chiyambi ndi mapeto umakhala wautali.
Concentric contraction: Pamene minofu ikugwirizanitsa, mtunda pakati pa chiyambi ndi mapeto amafupikitsidwa.
Zolimbitsa thupi za isokinetic eccentric zimakhala ndi mphamvu yophunzitsira mphamvu ya minofu kuposa momwe amachitira masewera olimbitsa thupi.Mwachitsanzo, kuchita masewera olimbitsa thupi kwa odwala pambuyo pa sitiroko kumatha kukulitsa luso lawo lokhazikika komanso kuthekera kochoka pakukhala mpaka kuyima kuposa kuchita masewera olimbitsa thupi okha.Izi zikutanthauza kuti, ma eccentric contractions a minofu amadziwika ndi kutsika kwamphamvu kwa minofu kumapangitsa kuti pakhale mphamvu zambiri poyerekeza ndi ma concentric contractions.Eccentric contraction imathanso kusintha kapangidwe ka ulusi wa minofu ndikupangitsa kutalika kwa ulusi wa minofu kumapangitsa kuti minofu ikhale yolimba.Pakusuntha kwa minofu yokhazikika komanso yokhazikika, masewera olimbitsa thupi atha kupanga mphamvu zolumikizana komanso kukwera msanga kuposa masewera olimbitsa thupi.Minofu simatsegulidwa mosavuta ikafupikitsidwa ndipo minofu imagwira ntchito mosavuta ikatalikitsidwa, chifukwa torque yambiri imapangidwa ikatalikitsidwa, kotero kuti zochitika za eccentric zimatha kuyambitsa contractility ya minofu kumayambiriro kuposa ntchito yokhazikika.Chifukwa chake, kuchita zinthu mopanda malire kuyenera kukhala chisankho choyamba chothandizira kukulitsa komanso kulumikizana kwa minofu.
Mphamvu ya minofu ndi yoposa mphamvu chabe.Ndizokhudzanso magwiridwe antchito a minofu, njira zowongolera minyewa, ndi chilengedwe, ndipo zimagwirizana mwachindunji ndi ntchito zogwirira ntchito.Choncho, kuphunzitsidwa kwa mphamvu ya minofu kuyenera kugwirizana ndi zinthu zomwe zili pamwambazi, ndikuwongolera khalidwe la minofu kupyolera mu maphunziro a mphamvu ya minofu kuti athe kugwira ntchito bwino.khalidwe kuti ligwire ntchitoyo bwino kwambiri.Zochita zamphamvu za minofu ya miyendo yakumtunda zimatsindika kusinthasintha, ndipo masewera olimbitsa thupi ndi ofunika kwambiri;masewero olimbitsa thupi a mphamvu ya minofu ya m'munsimu amatsindika kuthandizira koyimirira ndi kuyenda kopingasa kwa thupi, ndipo kugwirizanitsa kwa bondo, bondo ndi chiuno ndizofunikira kwambiri.
Kuphunzitsa mphamvu kwa magulu a minofu omwe ali ofooka (ofooka): Kuchita masewera olimbitsa thupi mobwerezabwereza kumatha kugonjetsa kutsegulira mwangozi pambuyo povulala muubongo, monga masewera olimbitsa thupi amodzi / angapo ophatikizika a antigravity / kukaniza kukweza, masewera olimbitsa thupi a bandi, masewera olimbitsa thupi, ndi zina zambiri.
Maphunziro a mphamvu ya minofu yogwira ntchito amapangidwa kuti awonjezere kupanga mphamvu, kuphunzitsa kayendetsedwe ka intersegmental ndi kusunga utali wa minofu kuti athe kupanga mphamvu pautali ndi ndondomeko ya zopinga zomwe zimagwirizanitsidwa ndi ntchito inayake, kuphatikizapo kusamutsidwa kwakukhala, kuyenda mmwamba ndi pansi masitepe, masewera olimbitsa thupi a squat, masewera olimbitsa thupi, etc.
Chitani ntchito zogwirira ntchito kuti muwongolere minofu yofooka komanso kusawongolera bwino kwa miyendo, monga kukwera ndi kutsika masitepe, kuyenda mozungulira, kufikira, kunyamula, ndi kuwongolera zinthu mbali zonse.
