The present study aimed to examine the associations between the TSL5 and TUG tests in the identification of sarcopenia, in association with multidimensional markers in older adults. This was a descriptive, cross-sectional study composed of 91 participants, recruited through non-probabilistic convenience sampling using a (snowball approach). Anthropometric and health-related data were collected using a questionnaire, in addition to the administration of the 5-Times Sit-to-Stand Test (TSL5), the Timed Up and Go Test (TUG), and Handgrip Strength (HGS), which was used to calculate the Muscle Quality Index (MQI). Statistical analyses assessed data distribution, group comparisons and correlations among variables. The sample was categorized into high (n = 66) and low (n = 25) functional capacity based on the TSL5, using a cutoff point of 15 seconds. The group with low functional capacity demonstrated poorer performance on the TUG, lower HGS, and higher medication use. Significant negative correlations were found between HGS and MQI with TSL5 time, and a positive correlation was observed between TSL5 and TUG. The TSL5 and TUG tests showed strong associations with functional capacity, proving to be sensitive tools for the early identification of sarcopenia. The study highlights the importance of preserving muscle strength and mass for maintaining functional autonomy and metabolic control in older adults, emphasizing the usefulness of simple and effective instruments in clinical practice and health programs aimed at the elderly population.
