Introduction: Aging is associated with a decline in both physical and cognitive functions, which is a common consequence of falls in older adults. In order to identify balance disorders and associated falls, a Timed up and go test is performed in practice, which allows the assessment of functional mobility, risk of falling, dynamic balance and gait. Frailty is a dynamic process characterized by a decrease in physiological reserves and a weakened resistance to stressors. It can be assessed using a Clinical frailty scale, which allows frailty in older adults to be identified early enough and treated appropriately so that it can be restored. Purpose: The aim of the master's thesis was to determine the relationship of Timed up and go test outcome with age, gender and frailty in mobile older adults in the Dom upokojencev Idrija. Methods: The study involved 48 investigators, aged over 65, who lived in the Dom upokojencev Idrija. Based on observation, interview and clinical assessment, we used a Slovenian translation of the Clinical frailty scale scale to assess the degree of frailty of the investigators. In the Dom upokojencev Idrija, we conducted Timed up and go test in the premises of the Intergenerational center. The investigators were able to use walking aids when performing the test, which they also use. Since the data were distributed normally, we used parametric tests. To verify the degree of correlation between Timed up and go test outcome and age of the investigators, we used Pearson's correlation coefficient (r). To verify the differences in Timed up and go test outcome between men and women, we used a t test for two independent samples. To verify the difference in Timed up and go test outcome and assess fragility with Clinical frailty scale, we used analysis of variance. Results: The calculated low correlation coefficient means that the Timed up and go test outcome was very low or not related to the age of the subjects. Timed up and go test outcome did not differ statistically significantly between men and women. Investigators who were more fragile had a statistically significantly worse Timed up and go test outcome than investigators who were less fragile. Discussion and conclusion: In our sample of subjects, age alone was not a reliable predictor of Timed up and go test performance, but other factors were likely to influence this. The investigators and the investigators were comparable in terms of functional mobility, as they achieved comparable Timed up and go test results. The most important finding of our study was that a higher score on Clinical frailty scale, reflecting a higher degree of frailty, was associated with the longer time needed to perform Timed up and go test. Further research should include larger numbers of respondents from different nursing homes and diverse geographic regions and use a longitudinal approach to monitor changes in Timed up and go test scores and Clinical frailty scale scores over time.
