Study aim: the aim of the study was to compare the postural stability and ability to control balance in active women who attend fitness classes versus inactive women.

Material and methods: the study included 41 women who exercise regularly (mean age 28.64±5.26 years). The control group consisted of 42 women not engaged in regular physical activity (mean age 28.55±5.05 years). In each subject, postural stability testing was performed using the Stabilometric Platform CQStab2P (the 2-platform version). Authors analysed the mean, median and standard deviation for each parameter of the stabilogram and statokinesiogram.

Results: for most of the studied parameters, the statistical analysis showed a positive effect of exercising on the level of fitness compared to the control group, for both the test with eyes open and the test with eyes closed.

Conclusions: attending fitness classes significantly affects postural stability and balance control in young women, and leads to lesser dependence on sight to maintain it.
