摘要：Objective. Determine the neuromuscular balance and lower limb lean mass status of Costa Rican first division professional soccer players based on tensiomyography data. Methods. We assessed 23 male professional soccer players (age 24.78 ± 3.90, height 175.43 ± 5.38 cm, weight 72.47 ± 6.28 kg, body fat 15.65 ± 5.14 %). Results. The analysis showed significant differences between dominant hemisphere (DH) and non-dominant hemisphere (NDH) for muscular displacement (Md) of biceps femoris (BF) (p=0.026), rectus femoris (RF) (p=0.047) and anterior tibialis (AT) (p=0.007) and sustain time (St) of adductor longisimus (AL) (p=0.026). Presence of lateral asymmetries in the muscles AL (43.75 %), BF (26.08 %), spinal erector (SE) (4.3 %), gastrocnemius lateralis (GL) (21.73 %), gastrocnemius medialis (GM) (17.39 %), RF (13.04 %), AT (21.73 %) and vastus lateralis (VL) (43.47 %). Lean mass results NDH (9.95 ± 0.99) and DH (9.94 ± 0.97). Conclusions. There are significant differences in the Md of BF, RF and AT and in the St of AL in the DH and NDH comparison, though not in most of the tensiomyography data of the lower limbs. There are no lateral, functional or lean mass asymmetries based on the means for Costa Rican first division players using technical parameters, although there are lateral asymmetries in isolated cases that are relevant in practical terms.
