Qhov sib txawv tseem ceeb ntawm qeeb thiab ceev twitch fibers yog qhov qeeb twitch fibers yog cov leeg nqaij fibers feem ntau siv rau kev ua kom ntev ntev xws li kev khiav deb thiab lawv tsis ua rau nkees yooj yim thaum ceev twitch fibers yog cov leeg nqaij siv rau Lub zog tawg ntawm kev txav mus los xws li sprinting thiab lawv tau nkees sai.
Muaj ntau yam sib txawv ntawm lub cev nqaij daim tawv. Ntawm cov nqaij sib txawv ntawm lub cev no, qee tus ntawm lawv ua haujlwm tsis txaus ntseeg. Ntawm cov leeg no, cov leeg pob txha yog cov leeg uas txav cov pob txha, caj npab thiab lub cev feem ntau. Cov leeg pob txha no muaj ob hom fiber ntau. Namely, lawv yog qeeb twitch fiber (hom I) thiab ceev twitch fiber (hom II). Feem ntau, tib neeg lub cev muaj qhov sib npaug ntawm cov fibers no. Txawm li cas los xij, nws tsis yog qhov xav tsis thoob uas yuav tsum nco ntsoov tias cov neeg sib tw khiav hauv Olympics muaj ze li 80% ntawm cov nrawm nrawm thiab cov neeg ua haujlwm marathon yuav luag 80% qeeb twitch fibers uas pab lawv hauv lawv cov xwm txheej. Nws yog vim hais tias peb muaj ntau feem pua pua ntawm qeeb thiab ceev twitch fibers hauv peb lub cev vim peb cov caj ces. Yog li ntawd, txawm tias koj xav ua tus khiav, txawm tias qhov haum rau koj nyob ntawm koj cov pleev fiber ntau raws li koj cov caj ces.
Slow Twitch Fibers yog dab tsi?
Slow twitch fibers (hom I) yog hom nqaij fibers uas sib cog lus maj mam. Cov fibers no pab nyob rau hauv ntev endurance heats xws li deb khiav txij li thaum lawv tiv taus qaug zog. Tsis tas li ntawd, cov fibers no muaj txiaj ntsig zoo hauv kev siv cov pa oxygen rau kev ua pa ntawm tes thiab hauv kev tsim cov ATP. Rau cov hom phiaj no, qeeb twitch fibers muaj ntau mitochondria.
Daim duab 01: Cov leeg nqaij
Raws li lawv tuaj yeem tuav cov pa kom zoo, lawv tuaj yeem tsim lub zog yooj yim yam tsis ua kom muaj cov lactic acid. Tsis tas li ntawd, cov fibers no muaj kev ua siab ntev txawm tias tsis muaj zog. Cov neeg ncaws pob khiav marathons ua zoo siv cov fibers no kom khiav mus ntev. Ntxiv mus, liab fibers yog lwm lub npe rau cov fibers vim lawv cov xim. Qhov ntawd yog; vim muaj cov ntshav nqa myoglobin ntau, lawv tau txais qhov tsos tsaus dua.
Twitch Fibers yog dab tsi?
Ntws nrawm fibers yog hom nqaij fibers uas cog lus sai. Vim tias cov fibers no tuaj yeem tsim lub zog ntau dua nyob rau lub sijhawm luv luv, lawv pab ua kom muaj zog tawg xws li sprinting. Yog li ntawd, nws ua rau lawv muaj zog ntxiv, thiab lawv ua kom nquag plias thiab tawg. Txawm li cas los xij, lawv tuaj yeem ua rau nkees nkees. Hauv cov lus yooj yooj yim, lawv qaug zog sai dua qhov qeeb twitch fibers thaum lub zog xav tau siab dua, lub cev recruits lossis ua kom nrawm nrawm cov leeg nqaij. Txawm li cas los xij, nws tsuas yog tshwm sim yog tias qhov qeeb twitch fibers tsis tuaj yeem ua tiav qhov kev thov quab yuam.

Ntxiv mus, qhov nrawm nrawm nrawm tshwm sim dawb vim lawv tsis muaj ntshav ntau. Yog li ntawd, lawv yog cov sib dua nyob rau hauv tsos dua li qeeb twitch fibers. Tsis tas li ntawd, ceev twitch fibers yog ob hom; uas yog, lawv yog tus ceev-twitch IIa thiab ceev-twitch hom IIb.
Dab tsi zoo sib xws ntawm Slow thiab Fast Twitch Fibers?
- Slow thiab Fast Twitch Fibers yog ob hom pob txha pob txha.
- Ob hom tsim lub zog thiab pab hauv kev txav.
- Kuj, ob qho tib si tsim muaj zog.
- Tsis tas li ntawd, ob hom fibers muaj nyob rau hauv qhov sib npaug ntawm tib neeg lub cev.
Qhov txawv ntawm Slow thiab Fast Twitch Fibers yog dab tsi?
Slow twitch fibers yog cov leeg nqaij fibers uas pab ua kom ntev ntev thaum ceev twitch fibers yog cov leeg nqaij fibers uas pab txhawb kev muaj zog thaum muaj kev ua siab ntev. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm qeeb thiab ceev twitch fibers. Raws li qhov muaj peev xwm ua tau zoo, cov neeg khiav mus ntev muaj qhov sib npaug ntawm cov qeeb qeeb qeeb qeeb thaum cov neeg caij luv luv uas koom nrog sprinting thiab lwm yam, muaj cov nqi sib tw ceev ceev.
Ib qhov sib txawv ntxiv ntawm qeeb thiab ceev twitch fibers yog tias qeeb twitch fibers tsis nkees sai dua thaum lub nrawm twitch fibers qaug zog sai dua. Ntxiv mus, lub peev xwm los tuav cov pa oxygen yog lwm qhov sib txawv ntawm qeeb thiab ceev twitch fibers. Qhov ntawd yog; qhov qeeb twitch fibers tuaj yeem tuav cov pa ntau dua rau kev ua pa ntawm tes ntau dua li qhov ceev twitch fibers.
Cov infographic hauv qab no muab cov ntaub ntawv ntxiv hais txog qhov sib txawv ntawm qeeb thiab ceev twitch fibers.
Summary – Slow vs Fast Twitch Fibers
Slow thiab ceev twitch fibers yog ob hom skeletal nqaij fibers. Slow twitch fibers sib cog lus maj mam thiab yog me ntsis qaug zog cov nqaij fibers. Ntawm qhov tod tes, ceev twitch fibers cog lus sai heev thiab muaj zog fibers. Li no, qhov no yog qhov sib txawv tseem ceeb ntawm qeeb thiab ceev twitch fibers. Tsis tas li ntawd, qhov qeeb twitch fibers tshwm nyob rau hauv liab vim lawv muaj ib tug ntau dua capillary ceev thaum ceev twitch fibers tshwm nyob rau hauv dawb vim hais tias lawv muaj ib tug tsawg capillary ceev. Tsis tas li ntawd, qeeb twitch fibers yog heev resistant rau qaug zog; yog li no, txhob nkees sai.
Ntawm qhov tod tes, cov twitch fibers nrawm nrawm dua rau kev qaug zog, yog li ua rau nkees yooj yim. Ntxiv mus, qeeb twitch fibers pab nyob rau hauv ntev endurance thaum lub ceev twitch fibers muaj tsawg endurance. Tsis tas li ntawd, lub nrawm nrawm fibers koom nrog hauv kev txav muaj zog vim lawv tuaj yeem tsim kom muaj zog ntau hauv lub sijhawm luv luv. Txawm li cas los xij, qeeb twitch fibers muaj mitochondria ntau dua li qhov nrawm nrawm fibers. Cov saum toj no yog cov ntsiab lus ntawm qhov sib txawv ntawm qeeb thiab ceev twitch fibers.
