Zeziphi iimethrikhi ezifunekayo kwiqela lamaqela ezihlunu aphikisanayo azinzisa umdibaniso?Umzekelo: i-biceps kunye ne-triceps, izihlunu zesisu kunye nezisezantsi, i-quadriceps kunye ne-hamstrings, i-triceps kunye ne-anterior tibialis, njl.Masiqale ngephepha ngokubaluleka kwe-ipsilateral hamstring ukuya kwi-quadriceps ratio (H: Q).
Eli linqaku elipapashwe nguMatheus Daros Pinto kunye no-Anthony J. Blazevich kunye noLars L. Andersen et al.kwiScandinavian Journal of Medicine & Science in Sports in 2018. Eli nqaku ligxininisa "Uphuhliso olutsha kwi-hamstring ukuya kwi-quadriceps ratio (H: Q)".Eli nqaku lidibanisa uphando lwangaphambili ukugqiba ukuba iimvavanyo zokubikezela ingozi yokulimala ngokubanzi, njenge-H: Q, ayibonakali ukuba yimimiselo emihle yokulimala okungaxhunywanga.Oku kungenxa yokuba olu vavanyo lwenziwa ngokuyimfuneko kwimeko engadinwanga, kodwa ukukhathala okongezelekayo kungumngcipheko obalulekileyo we-hamstring strains kunye nokulimala kwe-anterior cruciate ligament kwimilenze yabadlali bezemidlalo.Kwinqaku, emva kokuthelekisa imiphumo yeendlela ezahlukeneyo ze-H: ukubala kwe-Q, umphumo wokukhathala kwe-neuromuscular kwi-H: Q kunye nokulungelelaniswa phakathi kokukhathala kunye ne-non-fatigue state (H: Q) amanqaku omlinganiselo acatshangelwa, kunye nokuphindaphinda kwe-30 iimvavanyo zamandla emisipha ye-isometric zenziwa kwiimbaleki.
Iziphumo zovavanyo zibonise ukuba i-H: Q eqhelekileyo yayiyisiphumo sovavanyo lwe-centripetal contraction kunye nokucotha, ukuguquguquka kwamadolo kunye nokuguqa, ukuba i-angular velocity yamadolo yayiphezulu ngexesha lokuzilolonga kwangempela, kwaye ukunyakaza kwakudibaniso lwe-centripetal. – iipateni zokufinyela kwe-centrifugal.Idatha ibonisa ukuba ixabiso le-H: Q kwimeko yokudinwa likhulu kunezo zingekho kwimeko engapheliyo, kunye nokulungelelaniswa okubuthathaka phakathi kwezi zibini.Eli nqaku lijongene nesalathiso esibalulekileyo senkqubo yokuvavanya imisipha ye-isometric, umlinganiselo wexesha eliphakamileyo leemisipha ezisebenzayo kunye nezichasayo, ezichongwa ngumlinganiselo wexesha eliphakamileyo lamaqela amabini ama-muscle, asebenzayo kunye nomchasi, kwiindlela ezahlukeneyo zokuzilolonga kunye nezahlukeneyo. ii-angles ezihlangeneyo, kwaye ngokuqhelekileyo zisetyenziswa ngokuqhelekileyo kwimowudi ecothayo yokuzivocavoca ye-30-60 degrees / sec, okanye ngokweemfuno Izantya ezahlukeneyo zingasetwa ngokweemfuno.Ibonisa ibhalansi ye-muscle phakathi kwamaqela emisipha echaseneyo ngexesha lomsebenzi odibeneyo, kwaye ibaluleke kakhulu ekunqumeni ukuzinza ngokubambisana kunye nokuqikelelwa kokulimala okunokubakho, ngokukodwa ukuguqa kwedolo / ulwandiso lokwandiswa kwesigxina esisezantsi sibaluleke kakhulu ekusebenzeni kwekliniki.
