Abstract
<jats:p>Ultrasound imaging is a commonly used tool for imaging soft tissue structures, allowing for the quantitative determination of muscle size and structure. These morphological variables are important determinants of muscle strength and range of tension. So, ultrasound examination of the quadriceps femoris muscle to compare morphometric parameters of football players for recommendations on sports selection is relevant and requires further study. There are almost no works devoted to the study of morphometric parameters of the quadriceps femoris muscle using ultrasound. So, in order to compare the length and width of the quadriceps femoris muscle using ultrasound for selection into professional football, a study was conducted on young men aged 16 to 18 years. The main group consists of 32 young men, of whom Group I - 16 players of the team of masters of sports of Ukraine in football "University", Chernivtsi and Group II - 16 students of the I-II courses of the Faculty of Physical Culture and Human Health of Yuriy Fedkovych Chernivtsi National University. Group III - a control group, which consisted of 16 students of the I-II courses of the Bukovina State Medical University. The subjects of the control group did not play sports. The average body weight of the subjects is 78.50±2.26 kg, height - 180.40±2.36 cm. All subjects underwent a morphometric study using ultrasound diagnostics of the quadriceps muscle of the thigh (length, width). As a result, by comparing the length of the quadriceps muscle of the thigh, it was found that the greatest length was found in professional football players, compared to students who attended the football section and the control group, and the smallest length of the quadriceps muscle was found in the subjects of the III group, who did not additionally engage in sports. Also, by comparing the width of the quadriceps muscle of the thigh, it was found that the greatest width of the muscle was found in professional football players, compared to the II and III groups, and the smallest in the subjects of the III group, who also did not additionally engage in sports. So, ultrasound examination of the quadriceps muscle of the thigh has practical significance in terms of recommendations for the purpose of determining sports orientation and selection for professional football.</jats:p>
