11–14 yoshli maktab o‘quvchilari organizmida chidamlilikning rivojlanishi morfologik va funksional o‘zgarishlar orqali yuzaga keladi. Bu yosh davri yurak-qon tomir va nafas olish tizimlarining jadal shakllanishi, mushak massasining oshishi, energiya almashinuvining faollashuvi bilan xarakterlanadi. Anaerob va aerob imkoniyatlarning bosqichma-bosqich kengayishi chidamlilikni oshirishga zamin yaratadi. Tadqiqotda o‘quvchilarning biomexanik ko‘rsatkichlari, yurak urish tezligi, o‘pka sig‘imi, mushaklar elastikligi va chidamlilik mashqlariga moslashuv darajasi ilmiy asosda tahlil qilinadi. Ushbu ish pediatriya, jismoniy tarbiya metodikasi va sport fiziologiyasi kesishgan o‘rinda bo‘lib, boshlang‘ich sport tayyorgarligi jarayonida yuklamalarni individuallashtirish bo‘yicha tavsiyalar beradi.
