Physical performance was evaluated using a Short Physical Performance Battery (SPPB). The 4\u2005m gait speed and time for five repeated chair stands were analysed as secondary outcomes. Ninety-four participants were enrolled (mean age, 75 years; men, 58.5%; median SPPB, 10 points; \u22649 points, 42.6%). Quadriceps isometric strength was measured, and RFD values at two time points (RFD100, 0\u2013100\u2005ms; RFD200, 0\u2013200\u2005ms) were calculated from the slope of the force\u2013time curve. Maximal voluntary contraction (MVC) was also calculated. In all participants, the SPPB was significantly associated with RFD100, RFD200, and MVC. The 4\u2005m gait speed was correlated with RFD100, RFD200, and MVC, and the chair stand test time was negatively correlated with RFD100, RFD200, and MVC. Although these significant associations persisted after adjusting for age, sex, and body mass index or skeletal muscle mass, the association between RFD and physical performance was not significant after adjusting for MVC. Subgroup analysis revealed that the correlation coefficients between RFD and physical performance measures were greater in patients with low muscle mass than in those with preserved muscle mass. Similar results were observed for the secondary outcomes.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n
