Hiki ke kuhikuhi ʻia ke kūpaʻa hui i ka helu isometric - active to antagonist muscle moment ratio

He aha nā metric e pono ai no kahi hui o nā pūʻulu muscle antagonistic e hoʻopaʻa i kahi hui?No ka laʻana: biceps a me triceps, ʻōpū a me nā ʻiʻo haʻahaʻa, quadriceps a me nā hamstrings, triceps a me nā tibialis mua, a me nā mea ʻē aʻe.E hoʻomaka kākou me kahi pepa e pili ana i ke koʻikoʻi o ka ipsilateral hamstring a quadriceps ratio (H:Q).

He ʻatikala kēia i paʻi ʻia e Matheus Daros Pinto lāua ʻo Anthony J. Blazevich lāua ʻo Lars L. Andersen et al.i loko o ka Scandinavian Journal of Medicine & Science in Sports ma 2018. ʻO ka ʻatikala e pili ana i ka "New developments in the hamstring to quadriceps ratio (H:Q)".Hoʻohui ka ʻatikala i nā noiʻi mua e hoʻoholo ai i nā hoʻokolohua wānana hōʻeha maʻamau, e like me H: Q, ʻaʻole i ʻike ʻia he mau wānana maikaʻi no ka ʻeha pili ʻole.ʻO kēia no ka mea e hana maoli ʻia kēia mau hoʻāʻo ʻana i kahi kūlana luhi ʻole, akā ʻo ka luhi kumulative he mea koʻikoʻi koʻikoʻi no nā haʻalulu hamstring a me nā ʻeha cruciate ligament mua i nā wāwae o nā mea haʻuki.Ma ka ʻatikala, ma hope o ka hoʻohālikelike ʻana i nā hopena o nā ʻano like ʻole o ka helu H: Q, ua noʻonoʻo ʻia ka hopena o ka luhi neuromuscular ma H: Q a me ka pilina ma waena o ka luhi a me ka helu ʻole o ka luhi (H: Q), a me 30 repetitions o Ua hana ʻia nā hoʻokolohua ikaika o ka ʻiʻo isometric ma luna o nā mea pāʻani.

Ua hōʻike ʻia nā hopena hoʻāʻo ʻo ka H:Q maʻamau ka hopena o ka hoʻāʻo ʻana i ka centripetal contraction me ka hoʻolōʻihi ʻana o ke kuli a me ka hoʻololi ʻana, ʻoi aku ka kiʻekiʻe o ka angular velocity o ke kuli i ka wā o ka hoʻomaʻamaʻa maoli, a ʻo ka neʻe ʻana he hui pū me ka centripetal. – nā hiʻohiʻona hoʻokaʻawale centrifugal.Hōʻike ka ʻikepili he ʻoi aku ka nui o nā waiwai H:Q ma ke kūlana luhi ma mua o nā mea i loko o ka mokuʻāina luhi ʻole, me ka pilina nāwaliwali ma waena o nā mea ʻelua.ʻO ka ʻatikala e pili ana i kahi kikoʻī koʻikoʻi o ka ʻōnaehana hoʻāʻo isometric muscle, ka lakio o nā manawa kiʻekiʻe o nā ʻiʻo ikaika a me nā ʻiʻo antagonist, i hoʻoholo ʻia e ka ratio o nā manawa kiʻekiʻe o nā pūʻulu ʻiʻo ʻelua, ʻeleu a antagonist, ma nā wikiwiki hoʻoikaika ʻokoʻa a ʻokoʻa. nā kihi hui, a ʻoi aku ka maʻamau o ka hoʻohana ʻana i ke ʻano hoʻoikaika lohi o 30-60 degere/sec, a i ʻole e like me nā pono Hiki ke hoʻonohonoho ʻia nā wikiwiki like ʻole e like me nā pono.Hōʻike ia i ke koena o ka ʻiʻo ma waena o nā pūʻulu ʻiʻo antagonist i ka wā o ka hana hui, a he mea koʻikoʻi ia i ka hoʻoholo ʻana i ka paʻa ʻana o ka hui a me ka wānana ʻana i ka hōʻeha hui pū ʻana, ʻoi aku ka nui o ka nui o ke kuli flexion / extension ratio o ka ʻaoʻao haʻahaʻa i ka hana lapaʻau.
