The aim of this study was to evaluate the reliability of the vertical jump (VJ) using a contact mat in elderly women. Thirty-one physically active women aged 695 56 years participated in this study. Jump performance was evaluated with a contact mat. The first testing session (s1) consisted of four countermovement jumps interspersed with 40 s rest intervals. After a period of 5–7 days, volunteers performed the second session (s2) utilizing the same procedures. The intersession statistical analysis was calculated considering the two highest jumps, one obtained in each section. The intra-session analysis utilized all eight jumps, all four from each section, and the differences between means were calculated by repeated measures ANOVA. Reliability was tested using the intra-class correlation coefficient (ICC) and agreement by the Bland–Altman method. The intra- and intersubject variation percentage was calculated by the coefficient of variation (CV). Results: The intersession results displayed a high ICC (091; P
