This study aims the evaluation of the level, dynamics and direction of changes in the development of motor skills among early-school aged girls under the influence of a regularly practiced dance. The study involved 357 girls aged 7-10. The experimental group consisted of 192 girls attending dance classes at schools and children's dance groups. The physical fitness level was assessed by seven trials from the Eurofit test battery that allowed to determine the level of balance, speed of upper limb movement, flexibility, explosive strength of the lower limbs, static hand strength, strength endurance of the abdominal muscles and agility. Measurements were carried out twice with a 9-month interval during one school year. Test scores were used to determine profiles of motor skill levels for a group of dancing girls, standardised against the control group. The dynamics of changes were determined on the basis of percentage indicators for relative increments. The frequency of changes between measurements was expressed as the number of subjects in percentages. The dancing girls presented a higher level in six motor skills and changes in their physical fitness were more dynamic. Statistically, significant increases were found for balance, flexibility, static hand strength and agility.
