"Umvuthwandaba wesibili" - esinye sezimo ezingavamile nakakhulu ezingafundiwe zomzimba womuntu. Igcwele inkolelo-ze eminingi: abanye bathi le miphumela ivumela abadlali bezemidlalo abaphumelelayo, abanye - ukuthi awukwazi ukuyibeka kulo, ngoba lokhu kunzima ukuchaza.
"Umoya wesibili" - kuyini?
Ukuqinisekiswa kwesayensi enembile yekhulu lekhosenti yalesi simo akukhona. Odokotela banombono oseduze wokuthi yikuphi "umoya wesibili" osemidlalo. Imvelo yayo yemvelo ibonakala kulokhu okulandelayo:
- Ngesikhathi usebenza ngamandla kakhulu wonke imisipha kanye nesimiso sokuphefumula komzimba, ukukhathala okukhulu kwenzeka futhi ithoni iyancipha.
- Ngemuva kwesikhathi esinqunyiwe semaminithi angu-3 kuya ku-5 emva kokubonakala kokukhathala, kungenwe ngokungazelelwe kulungiswe ukunyakaza - lo mzwa uchazwa ngabantu abahlangana nabo ekuphenduleni umbuzo walokho "umoya wesibili" usho ukuthini.
- Emva kokuqeda ukukhathala kwezemidlalo ukukhathala kubuya, futhi imisipha iphinde iphele.
Izimpawu "zomoya wesibili"
Ukuhlukanisa ukuphakama kwamandla nge-flash of zeal akulula kakhulu, njengoba kubonakala ekuqaleni. Ukuze uzizwe ngendlela yayo, akukho ukuqapha okukhethekile noma ucwaningo oludingekayo. "Umoya wesibili" uma umthwalo wokugijima noma wezemidlalo uzizwa kanje:
- ukujwayelekile kokuphefumula nokushaya kwenhliziyo;
- ukunciphisa ukucindezeleka;
- ukubuyiswa kwe-acid-base balance of blood;
- ukunciphisa ukucindezeleka;
- ukuhamba okungavamile kwamalungu kanye nemikhawulo.
"Iphuzu elifile" nelithi "umoya wesibili"
Noma yimuphi umuntu ojwayele lesi simo uyazi ukuthi kunzima ukulinda okwenzekayo. Umsebenzi wesikhathi eside wesikhumba wenza ukuba kunciphise amandla okusebenza futhi kudala umuzwa wokukhathala ngokuphelele. Ukuphazamiseka emilenzeni nasezintweni, ukwehla kwevolumu yamaphaphu, i- tachycardia - zonke lezi zibonakaliso zivame ukwenza umsebenzi wezemidlalo ngesiqalo esinamandla kakhulu.
"Umoya wesibili" wabagijimi kanye nezinye izigaba zabagijimi uvuliwe ngemuva kokudlula "iphuzu elifile" - ukuphakama kwesigaba esinciphisa amandla, enikeza umbono wokuthi zonke izinto zomzimba ziphelile. Ungakwazi ukuwukhomba ngezimpawu zesici:
- Ukuphefumula okungenangqondo nokuvama okukhulu;
- ukujuluka okukhulu;
- ukwehla ku-ph-level yegazi;
- ukunciphisa oksijeni kumaseli.
Kungani "kuvulwa umoya" wesibili?
Ukuphefumula ngumsebenzi oqhubekayo womzimba womuntu ekushintshaniseni izinto phakathi kwamaseli omzimba kanye nemvelo yangaphandle. Izinqubo zezamandla ngokuxhumana okuvamile nemvelo yangaphandle - lolu hlobo lokuphefumula lubizwa ngokuthi i-aerobic. Ngokuzikhandla okuphindaphindiwe isikhathi eside, ukukhathala akunakugwema. "Ukuphefumula kwesibili" komuntu kuvulwa ngomkhawulo wamathuba, lapho amaphaphu edlulela emisebenzini ye-anaerobic, lapho inqubo yokucubungula oksijini ihamba kancane kunalokho okudingekile futhi ukushintshana kwamandla kwenzeka, njengokuthi, "esikweletini".
"Umoya wesibili" - i-biochemistry
Imithi yamakhemikhali eholele ekutheni kwenzeke amandla emzimbeni kuthiwa i-nucleotide adenosine triphosphate. Lona "uphethiloli" oyinhloko womzimba uma ulayishwa ngesikhathi sokuvula "ukuphefumula kwesibili". I-adenosine nucleotides yiyona ingxenye enkulu ye-metabolism yamandla kwanoma yisiphi iseli lomzimba womuntu. Izinto zokwakhiwa kwe-nucleotide yizinhlelo zamaprotheni nama-carbohydrate eziza nokudla. Indlela eqala ukuphefumula kwesibili komuntu ibukeka kanje:
- Njengoba umsebenzi we-muscle ukwanda, i-lipolysis ivela. I-oxydation ye-glucose ngokuhlanganyela kwe-oxygen.
- Njengoba i-fibre ye-muscle iqukethe inani elikhulu le-mitochondria, ama-hydrogen ions asheshe asetshenziswe futhi agcine umsebenzi we-anaerobic wamaphaphu.
- "Ukuphefumula kwesibili" emdlalweni kuwumphumela obangelwa yi-chemical reaction of acid pyruvic, ephenduka i-lactic acid (lactate), eguquguquka ibe yi-nucleotide adenosine triphosphate.
I-Physiology ye "umoya wesibili"
Ukuhunyushwa ngombono wamakhono omzimba womzimba kusegxile kakhulu ku- lactic acid kunezinto ze-adenosine. Ochwepheshe bokudla nezokuzivocavoca bayazi ukuthi "umoya wesibili" wabagijimi uvela ngokungavamile kakhulu. Kuye, kudingeka i-lactate ethile, engagcinwa kuphela uma kukhona ukungabi khona kwemisipha ende isikhathi eside. Ama-acidified tissues emzimbeni womuntu abhekwa njengesibonakaliso sezinkinga ezilandelayo:
- ukubambezeleka kokunciphisa umzimba;
- ukutholakala kwamanoni amaningi ngokweqile;
- umsebenzi okwanele wesistimu yokuphefumula;
- ukudla okungalungile;
- indlela yokuphila yangasese.
Indlela yokuvula "umoya wesibili"?
Ochwepheshe bezwe lemidlalo bayazi ukuthi ukuthembela ngokuphelele emoyeni wesibili kungaba yiphutha elikhulu, ngoba amathuba okubonakala kuwo wonke umuntu osebenzelana kahle ngezemidlalo ayinaki. Inkundla eyodwa evumela ukuthi ithonye ukuphuma kwamandla okuzenzekelayo ukugijima amabanga amancane namade. Kukhona izincomo zokuthola impendulo yombuzo wokuthi ungavula kanjani "umoya wesibili" uma usebenza:
- Ukunciphisa okwesikhashana ezingeni lomsebenzi womzimba ngaphambi komncintiswano obalulekile. Mhlawumbe, kungenzeka ukuthi akhohlise umzimba futhi akwenze "ukhohlwe" ngemithwalo yangaphambilini.
- Ukuqiniswa kokuphefumula nokunye ukuhamba. Izinhlanga ze-3-4 km zidinga ukuhamba ngenye ibanga elingama-5-8 km.
- "Umoya wesibili" ungathuthukiswa ngesikhathi sokuvivinya ezintabeni. Ukugijima ngokuphakamisa amathayi ngokushesha, ngakho-ke ithuba lokukhuphuka kwamandla landa.
