Imaphi amamethrikhi adingekayo eqenjini lamaqembu emisipha aphikisanayo azinzisa ilunga?Isibonelo: ama-biceps nama-triceps, imisipha yesisu nephansi emuva, ama-quadriceps nama-hamstrings, i-triceps kanye ne-anterior tibialis, njll. Ingabe la maqembu emisipha aphikisanayo ahlobene nokuvikela umgogodla nokuvikela amalunga?Ake siqale ngephepha ngokubaluleka kwe-ipsilateral hamstring to quadriceps ratio (H:Q).
Lesi isihloko esishicilelwe uMatheus Daros Pinto no-Anthony J. Blazevich kanye noLars L. Andersen et al.ku-Scandinavian Journal of Medicine & Science in Sports ngo-2018. Lesi sihloko sigxile kokuthi "Intuthuko entsha ku-hamstring kuya ku-quadriceps ratio (H:Q)".I-athikili ihlanganisa ucwaningo lwangaphambili ukuze iphethe ngokuthi izivivinyo zokubikezela ingozi yokulimala okuvamile, njenge-H:Q, akubonakali kuyizibikezelo ezinhle zokulimala okungaxhumene naye.Lokhu kungenxa yokuthi lezi zivivinyo empeleni zenziwa esimweni sokungakhathali, kodwa ukukhathala okwandayo kuyisici esibalulekile sobungozi bezinkinga ze-hamstring kanye nokulimala kwe-anterior cruciate ligament emilenzeni yabasubathi abangochwepheshe.Kulesi sihloko, ngemva kokuqhathanisa imiphumela yezindlela ezihlukene zokubala kwe-H: Q, umphumela wokukhathala kwe-neuromuscular ku-H: Q kanye nokuhlobana phakathi kokukhathala nesimo esingakhathali (H: Q) isilinganiso samaphuzu acatshangelwe, kanye nokuphindaphinda kwe-30 ukuhlolwa kwamandla emisipha ye-isometric kwenziwa kubasubathi.
Imiphumela yokuhlolwa ibonise ukuthi i-H: Q evamile yayiwumphumela wokuhlolwa kwe-centripetal contraction ene-slow, alternating knee extension and flexion, ukuthi i-angular velocity yamadolo yayiphakeme ngesikhathi sokuzivocavoca kwangempela, nokuthi ukunyakaza kwakuyinhlanganisela ye-centripetal. - amaphethini wokufinyela we-centrifugal.Idatha iphakamisa ukuthi amanani we-H:Q esimweni sokukhathala makhulu kunalawo asesimweni sokungakhathali, anokuxhumana okubuthakathaka phakathi kwakho kokubili.I-athikili ikhuluma ngenkomba ebalulekile yohlelo lokuhlola imisipha ye-isometric, isilinganiso sezikhathi eziphakeme kakhulu zemisipha esebenzayo nephikisanayo, enqunywa isilinganiso sezikhathi eziphakeme zamaqembu amabili emisipha, asebenzayo kanye nabaphikisi, ngesivinini esihlukile sokuzivocavoca kanye nokuhlukile. ama-engeli ahlangene, futhi ngokuvamile kuvame ukusetshenziswa kakhulu kumodi yokuzivocavoca enensa engu-30-60 degrees/sec, noma ngokwezidingo Izivinini ezihlukene zingasethwa ngokuya ngezidingo.Ibonisa ibhalansi ye-muscle phakathi kwamaqembu emisipha ephikisanayo ngesikhathi sokusebenza okuhlangene, futhi ibaluleke kakhulu ekunqumeni ukuzinza kwamalungu kanye nokubikezela ukulimala okungase kube khona, ikakhulukazi isilinganiso se-knee flexion / extension of the end engezansi sibaluleke kakhulu ekusebenzeni komtholampilo.
