The purposes of the study was to evaluate an effect of increasing balance task demands and visual tracking task demands, on stability and visual tracking performances, with possibility of any interaction among them. Twenty healthy participants were asked to perform various visual tracking tasks, with different attentional demands, while standing on various support surfaces. Two-way analysis of variance (ANOVA) with repeated measure design was performed to estimate significant effect. Support surface properties showed significant effects on stability measures but no significant effect on visual tracking performances were noticed. Significant effect of increasing visual tracking task demands on visual tracking performances were found. However, increasing visual tracking task demand did not show any significant effect on stability measures. Significant interaction effect was also found between surface properties and visual tracking task demands for stability measures. In conclusion, increasing balance demands effect stability and increasing visual tracking demands effect visual tracking performances.
