    PURPOSEThis study evaluated whether anthropometric measurements and the five times sit-to-stand test could be used to identify dynapenia. The cut-off values of accurate screening tools for identifying dynapenia were also established.MATERIALS AND METHODSThis was a cross-sectional study conducted on individuals ≥ 60 years old (N = 529). All participants underwent handgrip strength measurement, anthropometric measurements and the five times sit-to-stand test. The participants whose handgrip strength was < 28 kg for men and < 18 kg for women were considered to have dynapenia. The association between the recorded variables and dynapenia was determined using logistic regression, and cut-off values were established by performing the Receiver Operating Characteristic curve analysis.RESULTSThe prevalence of dynapenia was 35.42% in men and 25.61% in women. For males, both calf circumference (≤ 35.2 cm) and the five times sit-to-stand test (≥ 14.6 s) could be used as accurate tools for dynapenia. For females, only the five times sit-to-stand test (≥ 11.8 s) had sufficient accuracy to be used as a screening tool for dynapenia.CONCLUSIONSThe five times sit-to-stand test was an accurate screening tool for identifying dynapenia. The calf circumference could be only used as a screening tool in males.
