Abstract :The aim of this study was to evaluate the changes in muscle mass resulting from resistance training using B-mode ultrasound, circumference measurement, and circumference-based estimation of cross-sectional area, as well as to determine the predictive value of these three measurement methods for muscle mass changes. Thirty-five young males (age: 22.14±1.37 years, body weight: 76.37±8.38 kg, height: 178.89±6.35 cm, body mass index: 23.88±2.52) with experience in resistance training and currently engaged in resistance training voluntarily participated in the study. The quadriceps muscle thickness of the participants was measured using B-mode ultrasonography, thigh circumference was measured using a measuring tape, and quadriceps skinfold thickness was measured with a caliper at the thickest point (50%). The findings obtained demonstrated that following a 20-session resistance training program, B-mode ultrasonography, thigh circumference measurement, skinfold, and circumference-based estimation of cross-sectional area (CSA) could similarly detect the changes occurring in muscle mass (p< 0.05). The average percentage change was 23.7% for ultrasonography, 2.6% for thigh circumference, and 2.8% for skinfold and circumference-based estimation of cross-sectional area (CSA). Correlation analysis of the average differences obtained from the three measurement methods revealed a high positive relationship between circumference measurement and skinfold-circumference-based CSA (r = 0.826, p < 0.001). In conclusion, it can be stated that changes in muscle mass resulting from resistance training can be detected similarly through anthropometric measurements and ultrasonography. However, the magnitude of muscle mass change may vary depending on the measurement method used. Therefore, when comparing the increase in muscle mass across different resistance training interventions, the measurement methods should be taken into consideration.Keywords : Ultrasonografi, Çevre Ölçümü, Kas Kütlesi, Direnç Antrenmanı, Kas Hipertrofisi
