Abstract Background Low muscle strength has been focused on as an essential characteristic of sarcopenia, and the 30-s chair stand test (CS-30) could be a particularly useful for assessing strength. While it is speculated to beneficial tool assessment this remains verified. In study, we examined reliability optimal diagnostic score CS-30 sarcopenia in elderly Japanese participants. Methods This cross-sectional study included 678 participants (443 females 235 males) who underwent per Asian Working Group Sarcopenia (AWGS) 2019, test, isometric knee-extension test. ROC analysis was used estimate scores at which detected. Results were positively associated with (OR: 0.88; 95% CI:0.82–0.93). The AUC definition 0.84 ( p < 0.001) 0.80 males. number stands that predicted 15 (sensitivity, 76.4%; specificity, 76.8%) 17 males 75.0%; 71.7%). Conclusions found reliable screening population.
