Abstract:

Some studies have employed tensiomyography (TMG) to assess the effects of cold water exposure, recovery interventions (after training sessions), playing position, and different types of training on neuromuscular characteristics of muscles of the lower extremity in soccer players. However, the extend to which lower extremity dominance affects TMG characteristics in this population has not been reported to date. The purpose of this study was to compare the TMG characteristics between the dominant and non-dominant lower extremity in soccer players. Thirty-eight consecutive healthy male soccer players underwent resting TMG assessment of vastus medialis (VM), vastus lateralis (VL), rectus femoris (RF), semitendinosus (ST), biecps femoris (BF), gastrocnemius medialis (GM), and gastrocnemius lateralis (GL) in both lower extremities. The maximal displacement (Dm), delay time (Td), contraction time (Tc), sustained time (Ts), and half-relaxation time (Tr) were obtained, and compared between both sides. There were no significant between-group differences in any of the TMG parameters, except VM-Tc (p=0.008), VL-Tc (p=0.03), VL-Td (p=0.02), RF-Ts (p=0.009), RF-Tr (p=0.01), and BF-Ts (p=0.04). Therefore, in general, lower extremity dominance did not modify most of the TMG characteristics of the VM, VL, RF, ST, BF, GM, and GL in male soccer players.
