Kodi mungatani kuti mupeze phindu lamasewera m'njira yabwino kwambiri?

Kodi mungatani kuti mupeze phindu lamasewera m'njira yabwino kwambiri?

Ofufuza a Baylor ndi Stanford Colleges of Medicine ndi mabungwe awo ogwirizana amafotokoza lipoti lofalitsidwa mu Nature "Iwo adatha kuzindikira molekyu m'magazi omwe amapangidwa panthawi yochita masewera olimbitsa thupi ndipo amatha kuchepetsa kudya komanso kunenepa kwambiri mu mbewa.

Malinga ndi Neuroscience News, zomwe zapezazi zitha kuthandiza kuti asayansi amvetsetse momwe thupi limagwirira ntchito zomwe zimathandizira kuyanjana pakati pa masewera olimbitsa thupi komanso kuchepetsa njala.

kuchepetsa kunenepa

"Kuchita masewera olimbitsa thupi nthawi zonse kwasonyezedwa kuti kumathandiza kuchepetsa thupi, kuchepetsa chilakolako cha kudya komanso kusintha kagayidwe kake kagayidwe kake, makamaka kwa anthu olemera kwambiri komanso olemera kwambiri," anatero Dr. Yong Shu, pulofesa wa ana, zakudya ndi biology ya maselo ku Baylor College.

"Ngati ife (ochita kafukufuku) tingathe kumvetsetsa njira yomwe masewera olimbitsa thupi amachititsa kuti apindule nawo, tili pafupi kuthandiza anthu ambiri kukhala ndi thanzi labwino," anawonjezera.

"Kumvetsetsa momwe masewera olimbitsa thupi amagwirira ntchito pamagulu a maselo kudzatithandiza kuti tithe kupindula zina mwazopindulitsa," anatero wolemba mabuku wina dzina lake Pulofesa Jonathan Long, pulofesa wothandizira wa matenda ku Stanford Medicine komanso wofufuza ku Stanford Chem-H Institute.

Okalamba ndi ofooka

"Mwachitsanzo, anthu okalamba kapena ofooka omwe sangathe kuchita masewera olimbitsa thupi mokwanira tsiku lina akhoza kupindula ndi kumwa mankhwala omwe angathandize kuchepetsa kufooka kwa mafupa, matenda a mtima, kapena matenda ena," anawonjezera.

Amino zidulo

Xu, Long ndi anzawo adasanthula mwatsatanetsatane mankhwala a plasma otengedwa kuchokera ku mbewa atathamanga kwambiri pa treadmill. Molekyu yothandiza kwambiri inali amino acid yosinthidwa yotchedwa Lac-Phe. Amapangidwa kuchokera ku lactate, yomwe imachokera ku masewera olimbitsa thupi, omwe amachititsa "kuwotcha" mu minofu, ndi phenylalanine, amino acid yomwe ndi imodzi mwazinthu zomanga mapuloteni.

kulolerana kwa glucose

Makoswe onenepa kwambiri omwe amapatsidwa zakudya zamafuta ambiri adachepetsa kudya pafupifupi 50% poyerekeza ndi mbewa zowongolera pa nthawi ya maola 12, osasokoneza kayendedwe kawo kapena kugwiritsa ntchito mphamvu. Ikaperekedwa kwa mbewa kwa masiku 10, Lac-Phe idachepetsa kuchuluka kwa chakudya komanso kulemera kwa thupi (chifukwa cha kuchepa kwamafuta amthupi) ndikuwongolera kulolerana kwa shuga.

CNDP2 kuchepa kwa enzyme

Ofufuzawo adapezanso kuti puloteni yotchedwa CNDP2 ikukhudzidwa ndi kupanga Lac-Phe komanso kuti mbewa zomwe zilibe mu enzyme iyi sizinataye kulemera kwakukulu pa kayendetsedwe kazochita zolimbitsa thupi monga momwe adachitira ndi gulu lolamulira pa dongosolo lomwelo la masewera olimbitsa thupi.

Kuwonjezeka kwakukulu

Chochititsa chidwi n'chakuti gulu la ochita kafukufuku linapezanso kukwera kwakukulu kwa plasma Lac-Phe milingo pambuyo pochita masewera olimbitsa thupi pamahatchi othamanga ndi anthu. Deta yochokera ku gulu la anthu lomwe likuchita masewera olimbitsa thupi monga kuthamanga limasonyeza kuti panali kuwonjezeka kwakukulu kwa magulu a Lac-Phe, omwe adawonekera pambuyo pa sprinting ndikutsatiridwa ndi kukana kuphunzitsidwa ndi kupirira.

"Zotsatira zathu (gulu la ochita kafukufuku) zikuphatikizapo kupeza zambiri zokhudza momwe Lac-Phe imagwirizanirana ndi zotsatira zake m'thupi, kuphatikizapo ubongo," adatero Dr. Shaw. "
