Abstrakt     This study aims to determine the normalized response speed (Vrn) in vastus lateralis (VL) and biceps femoris (BF) muscles in different age groups using tensiomyography. Eighty-four male subjects were divided into four age groups: teenage subjects (T); undergraduate students (U), adult subjects (A), and the elderly group (E). Differences in Vrn were observed between E and T (p=0.000), E and U (p=0.000), and E and A (p=0.018) for right VL and between E and T (p<0.000) and U (p=0.003) for left VL; between T and U (p=0.010) and A (p=0.000) for right VL, and A (p=0.004) for left VL. Vrn in the BF displayed different behavior from that of the VL, increasing moderately or stabilizing and declining slightly in E, in right leg (p=0.020). The data obtained highlighted a decline in Vrn for the VL in both legs with increasing age and, declines in BF response speed were observed only in E
