The purpose of this study was to use TMG for the assessment of lateral symmetries (LS) and muscle response speed (Vrn) in elite futsal players in accordance with the specific position of the players. A total of 23 male elite futsal players competing in the Spanish elite championship were assessed. Five muscles were analysed: biceps femoris (BF), rectus femoris (RF), semitendinosus (ST), vastus lateralis (VL), and vastus medialis (VM). All assessments were carried out during the same period (i.e., inseason competition and on the recovery day of the microcycle). An analysis of variance of one factor for playing position and for muscle factor were performed on the parameter obtained (Vrn) for BF, RF, ST, VL, and VM. Cohen's d effect sizes were used to identify statistical differences. The results show that there are no muscle function differences between the dominant and non-dominant limb and no differences in lateral symmetries between muscles. Many differences were found between muscles but very few ones were found between playing positions. In conclusion, Vrn seems to be a useful parameter to assess the neuromuscular characteristics of the knee extensor and flexor musculature in futsal players during the season.
