Non-Linearity in Development of Dynamic Balance Repertoire in Middle Childhood

Area of Science:

• Child development
• Motor control
• Human movement science

Background:

• Current understanding of balance development in middle childhood relies heavily on static postural control tasks.
• Limited research exists on the developmental trajectory of dynamic balance during this age period.

Purpose of the Study:

• To investigate the development of dynamic balance in children aged 7-10 years using a virtual reality environment.
• To examine sex-based differences and the influence of covariates like height and perceived motor competence on dynamic balance strategies.

Main Methods:

• A virtual reality simulation was used for 354 children (boys and girls, aged 7-10 years) to cross a river on wide and narrow planks.
• Movement strategies were measured, and sex, height, and perceived motor competence were analyzed as covariates.

Main Results:

• Age was not a significant independent variable for any balance measures.
• Significant differences in dynamic balance strategies were observed between boys and girls.
• Task-specific strategies varied between sexes, suggesting different developmental pathways.

Conclusions:

• Dynamic balance development in middle childhood may follow a non-linear pattern.
• Boys and girls exhibit distinct task-specific strategies for dynamic balance, highlighting sex-based developmental differences.
• Further research into dynamic balance is needed to understand its complex development in children.
