To examine the association between daily moderate to vigorous physical activity (MVPA) and the change in mobility function among community-dwelling Japanese women aged 75 years and above.<jats:italic> Methods<\/jats:italic>. This prospective study included 330 older women aged 75 years and above who could walk without a walking device or assistance. MVPA and light-intensity physical activity (LPA) were assessed using an accelerometer for seven consecutive days. MVPA was defined as an activity with an intensity of &gt;3 metabolic equivalents. The study outcome was a change in mobility function, defined as the need of walking device or assistance, during the two-year period.<jats:italic> Results<\/jats:italic>. The results of the logistic regression analysis showed that MVPA was inversely associated with a decline in mobility function after controlling for LPA and potential confounders (adjusted odds ratio (OR) = 0.93 per 1\u2009min\/d, 95% confidence interval (CI) = 0.88\u20130.99; <mml:math xmlns:mml=\"http:\/\/www.w3.org\/1998\/Math\/MathML\" id=\"M1\"><mml:mrow><mml:mi>P<\/mml:mi><\/mml:mrow><\/mml:math> = 0.017), whereas LPA was not when adjusted for MVPA and confounders (adjusted OR = 0.99 per 1\u2009min\/d, 95% CI = 0.96\u20131.01; <mml:math xmlns:mml=\"http:\/\/www.w3.org\/1998\/Math\/MathML\" id=\"M2\"><mml:mrow><mml:mi>P<\/mml:mi><\/mml:mrow><\/mml:math> = 0.245). The receiver operating characteristics analysis identified a 7.9\u2009min\/d of MVPA as the cut-off value.<jats:italic> Conclusions<\/jats:italic>. The results of this study suggest the importance of promoting daily MVPA for preventing mobility limitation in older women aged 75 years and
