This paper explores the pathophysiological mechanisms underlying tumor development in detail. It focuses on the cellular and molecular changes that lead to tumor formation, such as genetic mutations, disruption of apoptosis, uncontrolled activation of growth factors, and the weakening of immune surveillance. The study provides a comprehensive overview of how tumor cells create a supportive microenvironment, including the stimulation of angiogenesis, evasion of the immune system, and the process of metastasis to distant tissues. Additionally, the paper examines the metabolic adaptations of tumor cells, their interaction with the surrounding tissues, and how these factors contribute to tumor progression.

Ushbu maqola 15–17 yoshdagi badmintonchilarning tezkorlik va kuch sifatlarini rivojlantirishga qaratilgan ilmiy-tadqiqot natijalarini o‘z ichiga oladi. Tadqiqotda maxsus mashg‘ulotlar tizimi tajriba va nazorat guruhlari o‘rtasida taqqoslash metodikasi asosida sinovdan o‘tkazildi. Tajriba guruhida 8 hafta davomida tezkorlik va mushak kuchi ko‘rsatkichlarini oshirishga yo‘naltirilgan mashg‘ulotlar olib borildi. Natijada sportchilarning harakat faoliyati, reaksiya tezligi va jismoniy holati sezilarli darajada yaxshilandi (p<0,001). Taklif etilgan metodika o‘smir badmintonchilarning tayyorgarligini yangi darajaga ko‘tarishda samaradorligini isbotladi va matematik-statistik tahlil orqali baholandi.

Mazkur maqolada 14-15 yoshli gandbolchi qizlarning musobaqa faoliyatini tahlil qilishga qaratilgan tadqiqotlar yoritilgan. Yosh sportchilarning texnik, taktik va jismoniy tayyorgarligi, musobaqa davomida ko‘rsatayotgan individual va jamoaviy natijalari tahlil qilinadi. Jismoniy tayyorgarlik, texnik mahorat va psixologik barqarorlikning o‘zaro bog‘liqligi va ularning sportchilarning muvaffaqiyatiga ta’siri ko‘rib chiqilgan. Shuningdek, raqobatbardosh faoliyatda sportchilarning harakatlari samaradorligini baholash usullari va ularni takomillashtirish bo‘yicha tavsiyalar berilgan.
