The Correlation Between Ultrasonography Based Muscle Architecture Parameters and Voluntary Isometric Muscle Strength

The goal of this study is to investigate potential relations of ultrasound-based muscle architecture parameters and isometric knee flexor muscle strength (IKFS) in healthy individuals. IKFS was measured for twenty participants (22.15±2.41 y.o; 8 females, 12 males) by a hand-held dynamometer. Investigated parameters were total and individual cross-sectional areas (CSA), Muscle-Thickness (MT), and pennation-angle (PA) for Biceps Femoris-long head (LBF), Semitendinosus (ST) and Semimembranosus (SM) muscles at 25%, 50% and 75% length of the thigh.
