Post-competition neuromuscular performance in professional football players in Costa Rica: tensiomyographic monitoring

Objective: To describe the neuromuscular behavior after competition in professional soccer players of Costa Rica through tensiomyographic monitoring.  Methods: 10 male players (age 27.78 ± 2.87 years, height 175.43 ± 4.04 cm, weight 69.00 ± 3.68 kg, body fat 13.17 ± 3.88 %), healthy, training 4-5 ti...

Sumario: Objective: To describe the neuromuscular behavior after competition in professional soccer players of Costa Rica through tensiomyographic monitoring.  Methods: 10 male players (age 27.78 ± 2.87 years, height 175.43 ± 4.04 cm, weight 69.00 ± 3.68 kg, body fat 13.17 ± 3.88 %), healthy, training 4-5 times per week. One tensiomyographic (TMG) measurement of rectus femoris was performed in its base state (LB) in preseason and about 24 hours after each of 4 official matches, comparing the values of contraction time (Tc) and muscle displacement (Dm), of the not dominant hemisphere (HND) and the dominant one (HD). Results: There are significant differences in Tc-HD between LB and fourth match (F = 567.62, p = 0.037), in Tc-HND between LB and fourth match (F = 506.90, p = 0.000), second match and fourth match (F = 506.90, p = 0.009), third and fourth match (F = 506.90, p = 0.001) and Dm-HD between the second and fourth match (F = 180.65, p = 0.022). Conclusions: The TMG values are similar to previous reported soccer TMG studies. There are significant differences in at least one value (Tc or Dm) obtained by TMG between LB (Tc-HD and Tc-HND), J1 (Tc-HND), J2 (Dm-HD) and J3 (Tc-HND) compared to J4 , getting closer, as the season goes on, to values reported for international football. This behavior corresponds to that expected in response to training.
