Values shown represent averages from the 1st measurement session in milliseconds for single (6 trials, 3 forward + 3 backward) and dual task (6 trials, 3 forward + 3 backward) ± 1 standard deviation. * Indicates statistically significant differences between age groups and +between task conditions within age groups, respectively (p < 0.05). P-value compares swing phase means ( ± 1 Standard Deviation) between the two groups were measured using Wilcoxon test and Mann-Whitney U test.
