Effects of a 10-Week Wushu Program on Static, Dynamic, and Dual-Task Balance and Physical Fitness in Preschool...

As a traditional Chinese exercise, Wushu has been shown to effectively promote balance and postural stability in various populations. Preschoolers' capacity for balance control, including static, dynamic, and dual-task balance, is linked to the later development of stability skills in adulthood. However, studies of Wushu intervention focusing on balance ability and the related physical fitness in preschool children are limited.

This study investigated the effects of a 10-week Wushu program on static, dynamic dual-task balance and physical fitness in children 5-6 years old.

Seventy-three participants were randomly divided into an intervention (INT, n = 39) and a control (CON, n = 34) group. The INT group participated in a 10-week Wushu program that included three 30 min sessions per week, while the CON group engaged in unstructured free play with purposely designed materials. The three key primary outcomes were dominant-leg stance for static balance, the balance beam walk for dynamic balance, and the center of pressure (CoP) path length obtained via a force platform during dual-task balance testing, in which the participants were instructed to count numbers backward. The five derived primary outcomes were non-dominant-leg stance, CoP ML path length, CoP AP path length, CoP sway velocity, and CoP sway area. Secondary outcomes were physical fitness indicators, including sit and reach, grip strength, standing long jump (SLJ), countermovement jump (CMJ), 15 m zigzag run, double-leg continuous jump, height and body weight. The analysis of the outcomes was conducted using analysis of covariance (ANCOVA) and Pearson correlation.

At baseline, the CON and INT groups did not differ significantly. The INT demonstrated significant enhancements in comparison with CON in the dominant and non-dominant-leg stance (p = 0.017 and p = 0.005, respectively), the balance beam walk, SLJ, 15 m zigzag run and double-leg continuous jump (all p < 0.05), along with the mediolateral CoP path length (p = 0.012). A strong correlation was found between the balance beam walk and the double-leg continuous jump (r = 0.55, p = 0.001), and between the balance beam walk and the 15 m zigzag run (r = 0.43, p = 0.015).

The present study demonstrates that a 10-week Wushu program significantly enhances preschool children's static balance, dynamic balance, and mediolateral postural control during dual-task condition. The improvements in dynamic balance are correlated with lower-limb coordination and jumping agility.
