Yoshlikdan boshlab muntazam mashg'ulotlarga qatnashgan futbolchilar professional yoki havaskor darajadagi musobaqalarga tayyorlanishadi. Ko'p yillar davomida amalga oshiriladigan treninglar (musobaqa) va bu treninglarning hissasi olimlar tomonidan o'rganilib, hisobot qilinadi. Shu o'rinda tadqiqotimiz murabbiylar yoki individual futbolchilar tomonidan ilmiy asosda qo'llaniladigan qo'shimcha mashg'ulotlar yosh futbolchilarning rivojlanishiga hissa qo'shishiga ishonamiz. Ushbu tadqiqotda yosh futbolchilarning mashg'ulotlariga qo'shimcha ravishda qo'llaniladigan turli xil mashg'ulotlar usullarining aerob, anaerob ko'rsatkichlari va nafas olish parametrlariga ta'sirini kuzatish va baholash muhimdir.

Tadqiqotimizning maqsadi - turli o'yin strategiyalarining ta'siriga mos ravishda, futbolchilarning pozitsiyalariga xos bo'lgan fiziologik, jismoniy va taktik yuklamalarni aniqlash. To'liq himoyachi, ochiq himoyachi va markaziy hujumchilar o'yin strategiyalariga ko'ra eng ko'p ta'sirlangan pozitsiyalardir. Garchi markaziy himoyachilar past jismoniy va fiziologik ko'rsatkichlarga ega bo'lishsada, o'yinchilarning yuklama ko'rsatkichlari charchoqqa olib kelishi mumkinligi kuzatilgan. Shu sababli, murabbiylar o'yin strategiyalarini pozitsiyalarga (egallagan o’rni) va mashg'ulotlarni rejalashtirishga ko'ra to'g'ri o'yinchilarni tanlashda hisobga olishlari kerak.
