This master's thesis was conducted with the aim of examining differences in selected asymmetric equilibrium parameters and their association with the percentage of subcutaneous adipose tissue in active retirees, in order to maintain and prevent the decline of motor abilities such as balance. The secondary objective was to determine the relationship between the percentage of subcutaneous adipose tissue and selected asymmetric equilibrium parameters. The study sample consisted of 63 active retirees (mean age 68.4 ± 5.2 years) who performed balance tests with both open and closed eyes. The results indicate a statistically significant reduction in asymmetry levels in all observed parameters during the test with closed eyes compared to the test with open eyes (p < 0.01). Additionally, a statistically significant difference in medio-lateral displacement between standing on the left and right leg with open eyes (p = 0.02) and in medio-lateral velocity, also with open eyes (p = 0.04), was observed. However, no statistically significant correlation was found between subcutaneous fat percentage and any of the selected balance asymmetry parameters. The results of this master's thesis emphasize the significance of early identification and interventions to reduce lower limb strength asymmetry, aiming to enhance balance, lower the risk of falls in the older population, and consequently reduce the risk of compromising their quality of life and mortality.
