Nthawi yabwino yosambira ndi mphindi 40 ndipo imakutengerani ku sayansi

Anthu ambiri akuyamba kusambira m'njira yawo yolimbitsa thupi. Komabe, anthu ambiri nthawi zambiri amalowa m'dziwe losambira, amakhala maola ambiri m'madzi, kwenikweni, izi sizolondola, nthawi yabwino kwambiri yosambira iyenera kukhala mphindi 40.
Kuchita masewera olimbitsa thupi kwa mphindi 40 kungathandize munthu kukhala ndi mphamvu inayake, komanso sikupangitsa kuti anthu atopa kwambiri. Glycogen, yomwe imasungidwa m'minofu ndi chiwindi cha thupi, ndiye chinthu chachikulu chomwe chimapereka mphamvu akasambira. Kwa mphindi 20 zoyambirira, thupi limadalira kwambiri ma calories ochokera ku glycogen; Mphindi 20 zina, thupi lidzaswa mafuta kuti likhale ndi mphamvu. Chifukwa chake, kwa anthu omwe akufuna kuchepetsa thupi, mphindi 40 zitha kukhala gawo lothandizira kuchepetsa thupi.
Kuphatikiza apo, madzi omwe ali m'madzi osambira amkati amakhala ndi chlorine, ndipo chlorine ikakhudzana ndi thukuta, imapanga nitrogen trichloride, yomwe ingawononge maso ndi pakhosi mosavuta. Kafukufuku watsopano ku United States akuwonetsa kuti kupeza chlorine pafupipafupi m'madzi osambira ambiri, komanso kuvulaza thupi, kumaposa kwambiri ubwino wosambira m'thupi, koma kulamulira nthawi yosambira kungapewe kuvulaza kumeneku.

Pomaliza, tiyenera kukumbutsa aliyense kuti chifukwa madzi ndi opereka kutentha kwabwino, mphamvu ya kutentha ndi yowirikiza ka 23 kuposa mpweya, ndipo thupi la munthu limataya kutentha m'madzi nthawi 25 mofulumira kuposa mumlengalenga. Ngati anthu alowa m'madzi kwa nthawi yayitali, kutentha kwa thupi kumatsika mofulumira kwambiri, padzakhala milomo yabuluu, khungu loyera, komanso kunjenjemera.

Choncho, osambira oyamba kumene sayenera kukhala m'madzi kwa nthawi yayitali nthawi iliyonse. Nthawi zambiri, mphindi 10-15 ndiye zabwino kwambiri. Musanalowe m'madzi, maseŵera olimbitsa thupi ayenera kuchitidwa kaye, kenako muzimutsuka ndi madzi ozizira, ndikudikira mpaka thupi LIZILOWERE kutentha kwa madzi lisanalowe m'madzi.
