Maximum VO2: Izvo zvazviri, maitiro ekuyera uye maitiro ekuwedzera - Utano

Zvemukati

Iyo yakanyanya VO2 inoenderana nehoriyamu yeokisijeni yakadyiwa nemunhu panguva yekuita kweaerobic chiitiko chemuviri, sekumhanya, semuenzaniso, uye inowanzo shandiswa kuongorora kugwinya kwemuviri kwemumhanyi, nekuti inomiririra kugona kweaerobic munhu nenzira yakanakisa. vanhu.

Izwi rekuti VO2 rinomiririra Maximum Oxygen Vhoriyamu uye rinonyatsoratidza kugona kwemuviri kutora okisijeni kubva mudenga uye kuendesa kumhasuru panguva yekushanda nesimba. Iyo yakakwira iyo VO2, inowedzera kugona kutora oxygen inowanikwa kubva mumhepo uye kuiisa kumhasuru zvakanaka uye nekukurumidza, zvinoenderana nekufema kwemunhu, kutenderera kweropa uye nhanho yekudzidzira.

Yakakwira yakakwira VO2 inoenderana nehutano mabhenefiti senge yakaderera njodzi yechirwere chemoyo, gomarara, kushushikana uye mhando yechipiri chirwere cheshuga, kunyanya nekuda kwetsika dzakanaka uye kugadzikana kwemuviri.

Ndeipi yakajairwa VO2

Iyo yepamusoro VO2 yemurume akagara anenge makumi matatu kusvika makumi matatu nemashanu mL / kg / min, nepo vamhanyi vane mukurumbira vemujaho vane VO2 max ingangoita 70 mL / kg / min.


Vakadzi vane, paavhareji, VO2 yakaderera zvishoma, kubva pa20 kusvika 25 mL / kg / min mune vakadzi vakagara uye vanosvika 60 mL / kg / min muvatambi nekuti ivo pachavo vane huwandu hwakawanda hwemafuta uye husina hemoglobin shoma.

Vanhu vanogara, kureva kuti, vasingaite zvekuita zvemuviri, vanogona kunatsiridza VO2 yavo nekukurumidza, zvisinei, vanhu vakatove vakadzidziswa uye vanoita zvemuviri nguva dzese, vangangotadza kuwedzera VO2 yavo yakawanda, kunyangwe ichigona kuvandudza kuita kwavo nenzira yakajairika. Izvi zvinodaro nekuti kukosha uku kunoenderanawo neyemunhu genetics, ndosaka vamwe vanhu vachikwanisa kuwedzera yavo VO2 munguva shoma yekudzidzisa.

Pamusoro peVO2 kuve nehukama nemageneti, inokosheswa nezera remunhu, dzinza, kuumbwa kwemuviri, danho rekudzidzira uye mhando yechiitwa chinoitwa.

VO2 max bvunzo

1. Yakananga kuyedza

Kuyera VO2, ergospirometry test inogona kuitwawo, inonziwo pulmonary test test kana bvunzo yekurovedza muviri, inoitwa pane yekutsika-tsika kana bhasikoro rekurovedza muviri, nemunhu anenge akapfeka chifukidzo kumeso uye nemagetsi akasungirirwa mumuviri. Iyi bvunzo inoyera zviyero zveVO2, kurova kwemoyo, kuchinjanisa gasi pakufema uye nekuona kushingairira zvinoenderana nesimba rekudzidziswa.


Muedzo unowanzo kumbirwa nachiremba wezvemwoyo kana chiremba wezvemitambo kuti aongorore vatambi, kana kuongorora hutano hwevanhu vanotambura nemapapu kana nematambudziko emwoyo, uye mune dzimwe nguva, huwandu hwe lactate muropa hunoyerwawo kumagumo bvunzo.

Uyezve ona kuti ndeipi chiyero chemwoyo chakanakira kurasikirwa uremu.

2. Kunanga kuedzwa

Iyo yakanyanya VO2 inogona zvakare kufungidzirwa zvisina kunangana kuburikidza nemuyedzo wemuviri, sezvazviri chiitiko cheCooper bvunzo inoongorora kugona kweaerobic, kuburikidza nekuongororwa kwedaro rakavharwa nemunhu mukati memaminitsi gumi nemaviri, uchifamba kana kumhanya pakukwirira kwakawanda.

Kana maitirwo akacherechedzwa, zvinodikanwa kuti uite kuverenga uchishandisa equation, iyo ichazopa iyo yakanyanya kukosha VO2 kukosha.

Tsvaga kuti bvunzo yeCooper inoitwa sei uye uone maitiro ekuona yakanyanya VO2.

Maitiro ekuwedzera iwo akanyanya VO2

Kuti uwedzere huwandu hweVO2 zvinodikanwa kuti uwedzere kurovedzwa kwemuviri nekuti unovandudza mamiriro ezvinhu epanyama, zvichiita kuti muviri utore oxygen nekuishandisa nenzira yakanakisa, kudzivirira kuneta. Kazhinji, zvinokwanisika kugadzirisa VO2 max neinenge 30% uye iko kuvandudzwa kunoenderana zvakananga nehuwandu hwemafuta emuviri, zera uye mhasuru uremu:


  • Huwandu hwemafuta: iwo mashoma muviri mafuta, iwo mukuru iwo VO2;
  • Zera: mudiki iye munhu, anowedzera yavo VO2 inogona kuva;
  • Misumbu: iyo yakakura tsandanyama, inowedzera kukura kweVO2.

Uye zvakare, kudzidziswa kwakasimba pamwe neinosvika 85% yemoyo kuroora kunobatsirawo zvakanyanya kuwedzera iyo VO2 mwero, asi sezvo ichi chiri chakasimba kudzidziswa, hazvikurudzirwe kune chero munhu ari kutanga kuita kwmuviri. Kutanga chiitiko chemuviri uye kuwedzera VO2, kudzidziswa kureruka kunokurudzirwa, iine 60 kusvika 70% yeVO2, iyo inofanirwa kugara ichitungamirwa nemudzidzisi wejimu. Uye zvakare, sarudzo yekuvandudza VO2 iri kuburikidza nekudzidziswa kwepakati, kunoitwa pakukwirira kwakanyanya.
