Effects of 8 weeks of rhythmic physical activity on gross motor movements in 4-5-year-olds: A randomized controlled trial.

OBJECTIVE

Rhythmic physical activity holds promise for positively influencing the gross motor development of 4-5-year-old children, yet empirical research in this domain remains limited. This study aimed to investigate the effects of rhythmic physical activity on the gross motor development in children aged 4-5 years.

METHODS

Fifty children aged 4-5 years were recruited and randomly assigned to either the intervention or control group. Both groups participated in a 10-week intervention program facilitated by a professional trainer, with support from numerous dedicated volunteers from reputable sports universities. This program comprised a one-week baseline assessment followed by 8 weeks of rhythmic physical activity training conducted three times per week. Gross motor performance was assessed using the PGMQ scale before and one week after the intervention.

RESULTS

Following the 8-week intervention, the intervention group demonstrated significant enhancements in displacement ability, with notable improvements observed in. Specifically, the scores for running, sliding lateral transfer, leaping step, two-footed back-and-forth jump, and total displacement ability showed significant increases (P < 0.05). Moreover, the total scores for running, standing long jump, sliding lateral transfer, leaping step, two-footed back-and-forth jump, and displacement ability exhibited significant differences between the intervention and control groups (P < 0.05). Regarding manipulative ability, the intervention group showed significant increases in scores for over-the-shoulder throwing, two-handed catching, and kicking (P < 0.05). Moreover, there were significant differences between groups in the scores for two-handed catching and kicking (P < 0.05). Concerning balance ability, the intervention group exhibited significant improvements in scores for single-leg stand, double-leg stand, and total balance ability (P < 0.05). No significant differences were observed in any of the indices within the control group (P > 0.05). The two-way repeated measures ANOVA of intervention × time revealed significant differences in scores for running, sliding lateral movement, leaping step, jumping back and forth with both feet, leading ability, kicking, manipulation ability, single-leg stand, double-leg stand, balance ability, and gross motor scores (P < 0.05).

CONCLUSIONS

This study underscores the beneficial impact of engaging in eight weeks of rhythmic physical activity on the gross motor development of 4-5-year-olds. Furthermore, the improvements in gross motor development achieved through rhythmic physical activity may surpass those obtained through general physical activity.
