Objective: To analyze functional capacity levels and the association between the Five-Repetition Sit-to-Stand Test (5STS) and the Timed Up and Go (TUG) as predictors of sarcopenia risk among the elderly. Methods: This descriptive, cross-sectional study included 91 participants, recruited through non-probabilistic convenience snowball sampling. Anthropometric and health data were collected via a questionnaire, in addition to administering the 5STS, TUG, and Handgrip Strength (HGS) tests, which were utilized to establish the Muscle Quality Index (MQI). Statistical analyses were conducted to evaluate data distribution, compare groups, and identify correlations between variables. Results: The sample was categorized into high (n= 66) and low (n= 25) functional capacity groups based on the 5STS, utilizing a 15-second cutoff point. The low functional capacity group demonstrated inferior performance on the TUG and HGS assessments and exhibited higher medication usage. Statistically significant negative correlations were identified between HGS and MQI with the 5STS duration, while a positive correlation was observed between the 5STS and TUG measures. Conclusion: The 5STS and TUG assessments demonstrated robust correlations with functional capacity, establishing them as sensitive instruments for the early detection of sarcopenia. This research emphasizes the significance of maintaining muscle strength and mass to sustain functional independence and metabolic regulation in older adults, and underscores the utility of straightforward and efficient tools in clinical settings and health initiatives directed at the elderly demographic.
