Panthawi imeneyi, kukula kwa mafupawo kwawonjezeka kufika pa masentimita asanu ndi awiri mpaka khumi, kulemera kwa thupi kuli kwayi ndi theka kufika pa kilogalamu zisanu ndi zinai pa chaka. Atsikana amasokoneza anyamata kwa zaka chimodzi kapena ziwiri pa mlingo wa kukula kwa thupi ndi kulemera kwa thupi. Mchitidwe wa ossification sunayambe. Kutalika kwa thupi kumayamba kuwonjezeka makamaka chifukwa cha kukula kwa thunthu. Kukulitsa minofu ya minofu, musakhale nayo nthawi yakukula kupitirira mafupa amtunduwu. Chiwerengero cha thupi ndi chikhalidwe cha minofu chimasintha. Mwa anyamata, patatha zaka khumi ndi zitatu kapena khumi ndi zitatu, minofu imakula mofulumira kwambiri kuposa atsikana. Pa zaka khumi ndi zinayi kufika khumi ndi zisanu, mitsempha ya minofu ikuyamba kufikitsa kukula kwa morphological.
Mtima umakula mwakuya, kutuluka kwake kwabwino, ziwalo zomangika ndi ziwalo zimapangitsa kuti pakhale ntchito yowonjezera. Kukula kwa mtima kumakhala mofulumira kwambiri kuposa kukula kwa mitsempha ya magazi ndipo chifukwa chake kumayambitsa kuwonjezeka kwa magazi ndi kutopa, komanso kusokoneza chiyero cha ntchito ya mtima. Mwazi umatetezedwa, kotero pakhoza kukhala kumverera kwachisokonezo mu mtima ndipo nthawi zambiri pamakhala mpweya wochepa.
Kusuntha kwa nthiti ndi kochepa ndi morphological dongosolo la thorax, chifukwa kupuma kungakhale kawirikawiri komanso mopanda phindu, ngakhale kupuma kuli bwino ndipo mapapo amakula. Komanso kumawonjezera mphamvu yambiri ya mapapo ndipo potsiriza amapanga mtundu wopuma: atsikana - thoracic, ndi anyamata - m'mimba.
Kusiyana kwa kugonana pakati pa atsikana ndi anyamata kumakhudza momwe thupi limagwirira ntchito komanso kukula kwa thupi. Atsikana poyerekezera ndi anyamata amakhala ndi chikwama chachikulu chapakhosi, thupi lalitali, miyendo yochepa. Zonsezi zimachepetsa luso lawo poponya, kulumpha, kuthamanga poyerekeza ndi anyamata. Minofu ya paphewa ndi yofooka kuposa anyamata, ndipo izi zimakhudza zotsatira zowokera, kuponyera, kukwera, kukweza, koma panthawi imodzimodziyo amapatsidwa pulasitiki ndi kayendedwe ka kayendedwe kake, zochita zolimbitsa kayendetsedwe ka kayendetsedwe kake komanso zofanana.
Ndondomeko ya mitsempha ndi machitidwe ake ali pansi pa chisonkhezero chowonjezereka cha zipangizo za endocrine. Mu nthawi yachinyamata, kutopa mwamsanga, kukhumudwa kochulukirapo ndi vuto la kugona ndizosiyana. Achinyamata ovuta kwambiri amatchula zochita zosalungama ndi zosankha. Zochitika kunja kwa chirengedwe ndi mphamvu ndizomwe sizikwanira poyerekeza ndi zovuta zomwe zimawapangitsa iwo.
Kotero, komabe, icho ndi khalidwe mu kukula kwa ana a sukulu ya sekondale. Anyamata kawirikawiri amatha kuwonetsa mphamvu zawo zamagalimoto, kuyesera kuchita zonse pawokha ndikudzimvetsa okha. Atsikana, osadalira kwambiri maluso awo.
Kawirikawiri, achinyamata amakhala ovuta kwambiri kuunika kwa akuluakulu, musalole kuti ziphunzitso, makamaka nthawi yayitali, ndizomwe zikuchitika mwatsatanetsatane ndi ulemu wawo.
Panthawiyi, pamene mukukonzekera maphunziro a zakuthupi, sikuli koyenera kulemetsa minofu, minofu ndi mgwirizano. Popeza katundu wambiri amachititsa kuti pang'onopang'ono kusokoneza thupi komanso kuchepetsa kukula kwa mafupa a tubula. Kuchita masewera olimbitsa thupi kumafuna kuchita masewera olimbitsa thupi omwe amachititsa kuti mitsempha ndi minofu ziwathandize, komanso kuchita masewera olimbitsa thupi. Musamapangidwe mofulumira kwambiri. Ndikofunika kulipira mwapadera kulondola kwa malo. Zochita zomwe zili ndi katundu wofunika pamtima, muyenera kusinthana ndi kupuma. Sizabwino kulekerera katundu wambiri, choncho ndi bwino kuti muthamange mozama ndikuyenda.
M'pofunikanso kugwiritsa ntchito kwambiri ntchito yopuma kupuma kuti mupitirize kupuma. Kuphunzitsa kupuma mwamasewero, mozama komanso popanda kusintha kwadzidzidzi mu tempo.
Mulimonsemo simungathe kugwirizanitsidwa mu gulu limodzi la atsikana ndi anyamata. Machitidwe ofananamo a atsikana ndi anyamata ayenera kuchitidwa m'madera osiyanasiyana osavuta kwa atsikana komanso mayina osiyanasiyana. Mtolowo uyenera kumasulidwa kulingalira za umunthu wa mwana aliyense. Atsikana amalimbikitsidwa kugwiritsa ntchito mitundu yosiyanasiyana ya masewera olimbitsa thupi ndi ma aerobics opangidwa ku nyimbo.
Kawirikawiri zaka za sukulu - ntchito za maphunziro zakuthupi ndi:
- kulimbikitsa chitukuko chakuthupi ndi thanzi;
- kufunika kokhala ndi luso loyendetsa magalimoto: kuthamanga kwa mphamvu, kuthamanga, mphamvu ya minofu, kupirira ndi kuyenda kwa ziwalo;
- Ndikofunika kulimbikitsa luso labwino pakuyenda komanso pamalo ovomerezeka;
- kupanga mapulogalamu olingalira komanso ogwira ntchito, komanso magulu othamanga pa malo okondana ndi osewera;
- Kuphunzitsa njira zoyenera kuchita masewera olimbitsa thupi, masewera olimbitsa thupi, kusambira, kusambira masewera olimbitsa thupi ndi kusewera, masewera (volleyball, basketball, mpira wa mpira, mpira wamanja);
- kukhala ndi chidziwitso ndi zofunikira zowonjezera katundu ndi kudziletsa panthawi yochita masewera olimbitsa thupi.
Njira zazikulu za maphunziro apamanja ku msinkhu wa kusekondale akugwiritsa ntchito poponya, kuchita masewera olimbitsa thupi, kukwera, kudumphira, kuthana ndi zovuta zowonongeka, zowonetsera masewera a masewera, komanso magetsi atsopano pa magalimoto oyendetsa galimoto: kukhala wathanzi ndi kuthamanga kwa ndege, ndi zina zotero.
