Postural control and muscle strength are important factors for the performance of everyday activities and reduce the possibility of fall-related injuries. The purpose of this study was to investigate the efficacy of a balance training program using action songs on balance and strength of preschool children. A total of 51 preschool children were randomly divided into an intervention group (25 children) and a control group (26 children). The intervention group received a balance training program

... ith action songs (six weeks, two times a week, total 12 sessions), while the control group followed the normal curriculum. Prior to and after the intervention, both groups were assessed in dynamic balance (walking on balance beams), static balance (single-leg stance on forceplate and Flamingo test) and strength (long jump and handgrip). The results showed that the intervention group performed significantly better in the dynamic balance and Flamingo test. There were no significant differences in the centre of pressure (CoP) displacement in the Medio-Lateral direction (CoP/ML), the Anterio-Posterior (CoP/AP), and the strength variables. The reliability of the single-leg test on the forceplate was moderate. Moreover, there were no correlations between balance and muscle strength variables. It can be concluded that the balance training program with action songs constitutes an effective activity for developing preschool children's balance, but not strength. Perhaps balance and muscle strength are independent of each other and may have to be trained with complementary activities. Moreover, the results of the study and the behaviour of the children during the one-leg stance test on the forceplate gave rise to questions regarding the appropriateness of this test for preschool children.
