Objectives: A lot of primary school students have inadequate posture and poor physical activity. There has been plenty of studies abroad revealing the positive effect of the dancing. With the research, our goal was that the survey of children’s posture, sense of balance, muscle extensibility and joint mobility, among children between 7-12 years who doing beginner Zumba Fitness.

Methods: The place of research is Szarvas, Hungary. Based on the voluntary application, 12 children from the Szarvasi Fit Life Team Sportclub beginner Zumba Fitness group were included in the sample. The exercise programs were held once a week for the 12-week period from September 02.09.2019.-30.11.2019. Measurements were taken in the week before the first time and after the 12th time. The trainings were performed once a week for 12 weeks for 45-50 minutes.

Results: The Stork Stand test (p = 0.01), and the Flamingo Balance test (p = 0.018) for the static equilibrium showed significant improvement. During the hip flexibility test similar results were obtained, compared to themselves (p =0.01) they showed a significant improvement. During the shoulder mobility the shoulder joint mobility significantly increased (p= 0.01). Between the two surveys, the value showed significant changes during the rotary stability (p =0.01). During the two surveys of the „stretching of the hind muscles while lying on the back’’ test, the values showed significant difference (p=0.194). The photographic analysis of children’s posture showed (p=0.02) significant improvement based on the photographs that were taken before the first training and after the last training.

Conclusions: Because of these results we can say that the systematic exercise is important from childhood. Such as the Zumba Fitness, what is an effective method for improving the children’s balance, muscle extensibility, joint mobility and posture.
