Comparison of posturographic parameters between young taekwondo and tennis athletes.

The study included only 29 male children and adolescents, so it does not tell us about girls or adults. The taekwondo and tennis groups were not randomly assigned and differed significantly in height and weight, so the balance difference may not be due to sport training alone. Participants were required to have trained in their sport for at least 6 months, but there was no maximum training history and the exact training history was not obtained. The test was quiet standing with eyes open, so it does not show how balance changes during sport-specific movement or competition. The authors noted the result did not match previous work and may be influenced by the young age and shorter training period of the participants.

The authors declared no conflict of interest, and no financing was reported.

Do not conclude that taekwondo training causes better balance in young athletes. The groups were compared by existing sport participation, not randomly assigned, and the taekwondo group was taller and heavier than the tennis group, so body size or other factors may explain the difference.
