Most studies are short, small, and in-person, limiting scalability. This study evaluated a 12-month digital moderate-to-vigorous physical activity intervention and its impact on long-term physical health outcomes in a large sample of cancer survivors.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>This 2-arm trial was embedded within the Cancer Prevention Study-3 prospective cohort study and included survivors with cancers associated with physical inactivity. Eligible participants were randomly assigned to a digital moderate-to-vigorous physical activity intervention or control group and completed 4 assessments (including surveys and accelerometry) across the 12-month intervention. Primary outcomes were total steps, step cadence (peak 1 minute and 30 minutes), 30-second sit-to-stand, self-reported mobility, walking pace, and pain. The primary analysis followed an intention-to-treat approach, with subgroup analyses by website engagement and among those with poor outcomes at baseline.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>In total, 415 were randomly assigned (intervention: n\u2009=\u2009286; control participants: n\u2009=\u2009129), and 391 were included in the analysis. The intervention did not statistically significantly affect total steps, mobility, walk pace, or pain. However, website-adherent participants showed higher peak cadence (adherent: 125 steps per minute vs nonadherent or control participants: 121-122 steps per minute) and clinically meaningful improvement in sit-to-stand performance (average increase: 13-16, P\u2009&amp;lt;\u2009.001).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>In intention-to-treat analyses, there were no statistically significant changes in most physical health outcomes.
