Abstract
Background
Tensiomyography (TMG) is a relatively new technique that assesses the contractile properties of muscles in response to a single electrical stimulus. This study aimed to evaluate the contractile properties of the gastrocnemius and tibialis anterior (TA) muscles in amateur soccer players using TMG.
Methods
We recruited 41 male soccer players (high school group, n=21; college group, n=20). The gastrocnemius medialis (GM), gastrocnemius lateralis (GL), and TA muscles of both lower extremities were assessed using TMG. The maximal displacement (Dm), delay time, contraction time (Tc), sustained time, and half-relaxation time were obtained and compared between the two groups.
Results
First, both groups showed low Dm for the GM and TA muscles, which indicated high stiffness of the muscle tone. Second, the Tc and contraction velocity (Vc) were high for all muscles, except for the GL showing lower speed than the other muscles, which represented the sports-specific characteristics of the soccer players. Third, there were no significant differences in the measurement variables between the dominant and non-dominant sides, except for the Tc of the GM in high school athletes and Vc of the TA in college athletes.
