        <p>The article is devoted to the study of the biomechanical analysis of the lead straight punch (jab) across different skill levels in boxing. This study examines novice, intermediate, and elite boxers, focusing on various biomechanical parameters such as punch speed, force, shoulder and torso rotation, hip alignment, and energy transfer.</p>
        <p>The lead straight punch, or jab, is fundamental in boxing, impacting both offensive and defensive strategies. This study provides an in-depth biomechanical analysis of the lead straight punch among novice, intermediate, and elite boxers using mathematical and statistical methods. Through motion capture and high-speed video analysis, we examine differences in punch speed, force, shoulder and torso rotation, hip alignment, and energy transfer. Our findings, supported by statistical analysis and diagrams, reveal significant variations in biomechanics across skill levels, offering insights for optimizing training programs.</p>

        <p>Статья посвящена исследованию биомеханического анализа прямого удара передней рукой (джеба) у боксёров разного уровня мастерства. В данном исследовании рассматриваются начинающие, боксёры среднего уровня и боксёры элитного уровня, при этом внимание уделяется различным биомеханическим параметрам, таким как скорость удара, сила, вращение плеча и корпуса, положение бёдер и передача энергии. Прямой удар передней рукой, или джеб, является основополагающим в боксе и влияет как на атакующую, так и на защитную тактику. В данном исследовании представлен углублённый биомеханический анализ прямого удара передней рукой у начинающих, боксёров среднего уровня и элитных боксёров с использованием математических и статистических методов. С помощью захвата движения и высокоскоростного видеоанализа мы исследуем различия в скорости удара, силе, вращении плеча и корпуса, положении бёдер и передаче энергии. Наши результаты, подкреплённые статистическим анализом и диаграммами, выявляют значительные различия в биомеханике на разных уровнях мастерства, предоставляя сведения для оптимизации тренировочных программ.</p>

        <p>Maqola boksda turli mahorat darajasidagi sportchilarning oldingi qo‘l bilan to‘g‘ri zarbasi (jeb) ning biomexanik tahlilini o‘rganishga bag‘ishlangan. Ushbu tadqiqotda boshlang‘ich, o‘rta va elita darajasidagi bokschilar ko‘rib chiqilib, zarba tezligi, kuchi, yelka va tana aylanishi, son holati hamda energiya uzatilishi kabi turli biomexanik parametrlarga e‘tibor qaratiladi. Oldingi qo‘l bilan to‘g‘ri zarba, ya‘ni jeb, boksda asosiy zarba hisoblanadi va hujum hamda himoya taktikasiga ta‘sir ko‘rsatadi. Ushbu tadqiqotda matematik va statistik usullardan foydalangan holda boshlang‘ich, o‘rta va elita darajasidagi bokschilarda oldingi qo‘l bilan to‘g‘ri zarbaning chuqur biomexanik tahlili keltirilgan. Harakatni qayd etish va yuqori tezlikdagi videotahlil orqali biz zarba tezligi, kuchi, yelka va tana aylanishi, son holati va energiya uzatilishidagi farqlarni o‘rganamiz. Statistik tahlil va diagrammalar bilan tasdiqlangan natijalarimiz mahorat darajalari bo‘yicha biomexanikada sezilarli farqlarni ochib beradi va mashg‘ulot dasturlarini optimallashtirish uchun ma‘lumot beradi.</p>
