I-lactic acid izihlunu - umhlobo okanye utshaba?

Abo inxaxheba abanxibe impahla, eziqhelekileyo imvakalelo esibuhlungu elivuthayo izihlunu, nto leyo ekugqibeleni yenza ukuba ayeke lo msebenzi. Le ntlungu eyenziwe ngexesha intshukumo lactic acid izihlunu. Indlela ukuba zazise okubhalwe kule mba kwaye nokuba kunokwenzeka ukuba siqwalasele oko kuyingozi?

Lactic acid koko zizazinzulu umlamli zengqo- ngexesha ukutya ekudleni. Carbohydrate, leyo zithathwa njengomthombo wamandla ukuba izihlunu zethu, lisebenza emzimbeni, eziguqulelwe kwi glucose. Uninzi glucose engena egazini, ngokudlulisela isibindi kwaye engena izihlunu. Apha kule nkqubo soguqulo yayo lactic acid.

I-lactic acid kwi esihlunwini iqulathe amacandelo amabini: zincancise ion kunye hydrogen ion. Into yokugqibela, kwaye kuyabuya ukutshisa kakhulu okubuhlungu ukuba kunjalo na ingxaki ngexesha loqeqesho. Uphazamisane iziganeko enikwa yi-luvo kunye nezihlunu, kunciphisa zokurhwaqela kwezihlunu kunye oonobangela deceleration ngayo amandla. Ekubeni ngexesha uqeqesho carbons ukusetyenziswa okukhawulezayo, lactic acid ukunyuka izinga lemveliso. Kwiimeko eziqhelekileyo, ayifiki ngokukhawuleza ukusuka izihlunu ngqo kwi egazini uze esibindini, kuphi na "izinto zokwakha" kulwenziwo glycogen. Kodwa kuphela esibindini ufumana ikota kobungakanani yayo; abanye isetyenziswa zibe kukudla imicu izihlunu "slow". Ngoqeqesho olunzulu lactic acid akukho ukuphatha njengefunyanwe kwezihlunu kwaye oqokelela apho, ebangela ubuhlungu eziqhelekileyo. Yimeko apho lactic acid oluhlala kuzo izihlunu ngokukhawuleza ngaphezu imveliso ye ekuthiwa embundwini zincancise. Kuba luvo loo kwinqanaba lactic acid - lo umqondiso ukuba umzimba kufuneka ikhefu. Kukho ukuncitshiswa yokumpompoza kwegazi, nto leyo ebangela yimvakalelo ukudinwa.

Lactic acid kudla ukwathulelw zoyikekayo emangalisayo. Umzekelo, intsomi eqhelekileyo kukuba esiti lactic kwi imisipha unobangela intlungu uphathwe emva umthambo. Enyanisweni, umgangatho uqala ukuba ehlise ngoko nangoko emva kokuba nokupheliswa kwempangelo. Kwaye ukuba uziva intlungu izihlunu emva kweentsuku ezimbalwa emva kokuba umsebenzi, i-lactic acid akuyona into yokwenza nalo - ukuba akukho nto nje. Kulo mzekelo, unobangela discontinuities kukho izihlunu ifayibha amalaphu (ukuba kwenzeka kwi ubunzima ukunyuka) okanye ukudumba. Ukuxhuzula nako kwenzeka ngenxa yokuba i receptors izihlunu overexcited fatigue kwezihlunu.

Njengoko ubona, lactic acid kunye neentlungu kwezihlunu zinxulumana kuphela ngexesha loqeqesho. Ukuze arhoxe ngokukhawuleza ukusuka izihlunu iziyobisi, iimbaleki badla babhenele iibhate ezishushu zokuthambisa. Kodwa ezi ndlela, uhlolisiso lubonisa ukuba akazange kuchaphazela umgangatho lactic acid. Kuninzi kakhulu luncedo esebenzayo, oko kukuthi, ukutshintsha umthwalo izihlunu. Ngoko ke, inkoliso iinkqubo zoqeqesho yenziwe ukuze alternate kunye umthambo enzima nokunyamezela umthambo. uqeqesho ukunyamezela, ezifana njengomtyibilizi, ngebhayisekile okanye ukuqubha, ukunceda izihlunu ukuqhelana imithwalo, nayo leyo ivumela ekunyuseni izinga imveliso ye lactic acid ukusuka ijwabu kwezihlunu.

Ngoko ke, le asidi lactic kwi izihlunu - kodwa kunokuba umncedisi wethu. Sisebenza njengomthombo wamandla ukuba izihlunu zethu izinto ekuveliseni glycogen. Amafutha isebenzisa, kwaye inkqubo yokujikeleza kwegazi, awakukhupha ngazo lactic acid udlula ukusuka kwelinye ukuya kwelinye imicu izihlunu, kwakunye esibindini. Ke ukuba ukudinwa emva umthambo, kukho edlala indima enkulu nedayethi yembaleki. Ubukho oluninzi carbohydrate ekutyeni kunceda ukuba bazalise oovimba glucose kunye glycogen, iindleko eklasini, nto leyo, kunciphisa ixesha elifunekayo ukuze achache emva ukusebenzisa.
