Research regarding the complex fluctuations of postural sway in an upright
standing posture has yielded controversial results about the relationship between
complexity and the capacity of the system to generate adaptive responses. The aim
of this study is to compare the performance and complexity of two groups with
different levels of expertise in postural control during a balance task. We
examined the balance ability and time varying (dynamic) characteristics in a
group of 18 contemporary dancers and 30 non-dancers in different visual
conditions. The task involved maintaining balance for 30s on a stability platform
with opened or closed eyes. The results showed that dancers exhibited greater
balance ability only in open eyes task than non-dancers. We also observed a lower
performance in both groups during the test with closed eyes, but only dancers
reduced their complexity in closed eyes task. The main conclusion is that the
greater postural control exhibited by dancers depends on the availability of visual information.
