Background: The postural and neuromuscular performances in healthy children taekwondo (TKD) practitioners in comparison with control children were examined.
Methods: Seventeen healthy pre-pubertal males undertaking only physical education at school (age: 11.88 ± 0.33 years) and 12 pre-pubertal male TKD practitioners (>3 years, 4 sessions a week) (age 11.66 ± 0.49 years) were recruited. Performances in the dynamic postural control (Star Excursion Balance Test -SEBT), vertical jump [squat jump (SJ) and countermovement jump (CMJ)] and sprint running (distances: 5, 10, 20 and 30 m) tests were compared between the two groups.
Results: The performances of the TKD practitioners were better than those of the non-TKD active for the SEBT (for 14 of 16 conditions, p < 0.05), SJ (p < 0.01), CMJ (p < 0.03) sprint running (5 m, p < 0.01; 10 m, p < 0.04; the performances for the 20 and 30 m sprints were not significant, p > 0.05).
Conclusions: TKD practice would stimulate sensory input and motor output of the postural system that would enhance its efficiency. In addition, the dynamic nature of TKD would develop the muscle power of the lower limbs. In our sample of healthy pre-pubertal males, TKD appears to improve postural and neuromuscular functions, but further research is required.
