Kukhazikika kophatikizana kumatha kutumizidwa ku index ya isometric - yogwira ntchito kwa antagonist muscle moment ratio

Ndi ma metric otani omwe amafunikira pagulu lamagulu otsutsana omwe amakhazikika pamgwirizano?Mwachitsanzo: biceps ndi triceps, mimba ya m'mimba ndi yotsika kumbuyo, quadriceps ndi hamstrings, triceps ndi anterior tibialis, ndi zina zotero.Tiyeni tiyambe ndi pepala pa tanthauzo la ipsilateral hamstring to quadriceps ratio (H: Q).

Iyi ndi nkhani yofalitsidwa ndi Matheus Daros Pinto ndi Anthony J. Blazevich ndi Lars L. Andersen et al.mu Scandinavian Journal of Medicine & Science in Sports mu 2018. Nkhaniyi ikufotokoza za "Zatsopano zatsopano mu hamstring to quadriceps ratio (H: Q)".Nkhaniyi ikuphatikiza kafukufuku wam'mbuyomu kuti atsimikizire kuti mayeso olosera zangozi zowopsa, monga H: Q, sizikuwoneka ngati zolosera bwino za kuvulala kosalumikizana.Izi ndichifukwa choti mayeserowa amachitidwa m'malo osatopa, koma kutopa kowonjezereka ndi chinthu chofunikira kwambiri pamavuto a hamstring ndi kuvulala kwapambuyo pamiyendo ya akatswiri othamanga.M'nkhaniyi, mutatha kuyerekezera zotsatira za njira zosiyanasiyana za H: Q kuwerengera, zotsatira za kutopa kwa neuromuscular pa H: Q ndi mgwirizano pakati pa kutopa ndi dziko lopanda kutopa (H: Q) chiwerengero cha chiwerengero chinaganiziridwa, ndi kubwereza kwa 30 mayesero a mphamvu ya minofu ya isometric anachitidwa pa othamanga.

Zotsatira za mayesero zinasonyeza kuti H: Q yachibadwa inali zotsatira za kuyesa kwapakati pa centripetal contraction pang'onopang'ono, kusinthasintha kwa mawondo ndi kupindika, kuti kuthamanga kwa mawondo a bondo kunali kwakukulu panthawi yochita masewera olimbitsa thupi, komanso kuti kayendetsedwe kameneka kanali kophatikizana ndi centripetal. - centrifugal mapangidwe mapangidwe.Detayo imasonyeza kuti zikhalidwe za H: Q mu mkhalidwe wotopa zimakhala zazikulu kuposa zomwe sizili otopa, ndi mgwirizano wofooka pakati pa awiriwo.Nkhaniyi ikukhudzana ndi ndondomeko yofunikira ya dongosolo loyesa minofu ya isometric, chiŵerengero cha nthawi zapamwamba za minofu yogwira ntchito ndi yotsutsa, yomwe imatsimikiziridwa ndi chiwerengero cha nthawi zapamwamba za magulu awiri a minofu, yogwira ntchito ndi otsutsa, pamasewera osiyanasiyana othamanga komanso osiyana. ma angles olowa, ndipo nthawi zambiri amagwiritsidwa ntchito pochita masewera olimbitsa thupi pang'onopang'ono a 30-60 madigiri / sec, kapena malinga ndi zosowa Kuthamanga kosiyana kumatha kukhazikitsidwa malinga ndi zosowa.Imawonetsa kusinthasintha kwa minofu pakati pa magulu otsutsana ndi magulu otsutsana nawo panthawi yogwirizanitsa ntchito, ndipo ndizofunikira kwambiri pozindikira kukhazikika kwa mgwirizano ndi kulosera zomwe zingatheke kuvulazidwa pamodzi, makamaka mawondo a mawondo / kuwonjezereka kwa m'munsi kumakhala kopindulitsa kwambiri pazochitika zachipatala.
