Relationship between isokinetic dynamometry and tensiomyogrphy in individuals with different muscle power manifestation


Toskić Lazar


The aim of this study was to investigate the correlations between isokinetic dynamometry and tensiomyography (TMG) in individuals with different levels of muscle power manifestation. The sample consisted of 85 male participants divided in three groups according to their levels of muscle power manifestation: low (LMP), average (AMP), and high (HMP). Isokinetic dynamometry was used to measure average muscle power of knee joint extensor and flexor muscles of the knee joint of the dominant leg at angular velocities of 60 º/s and 180 º/s, while tensiomyography measured maximal displacement (Dm) and contraction time (Tc) of the main knee joint extensor and flexor muscles: rectus femoris and biceps femoris. Correlation analysis revealed some significant correlations between the parameters obtained by isokinetic dynamometry and tensiomyography, the highest being in the LMP group (r = -0.461, p = 0.021, on average), and the lowest in the HMP group (r = -0.564, p = 0.045). These findings indicate that the correlation between the results obtained by these two methods weakens with the increase in muscle power manifestation, and that this increase depends to an extent on muscle contraction velocity and muscle stiffness, while high muscle power manifestation is influenced by other factors.
