Physical activity (PA) is a modifiable factor for sarcopenia prevention, but the role of activity intensity and dose remains uncertain. Evidence from Chinese cohorts is especially scarce.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>We analyzed data from 6018 adults in the China Health and Retirement Longitudinal Study. Sarcopenia was defined using the 2019 Asian Working Group for Sarcopenia criteria. PA was self\u2010reported and categorized into high\u2010 (HPA), moderate\u2010 (MPA), and low\u2010intensity (LPA), as well as total PA. Logistic regression models estimated odds ratios for sarcopenia, and Cox regression assessed associations with 10\u2010year all\u2010cause mortality. Subgroup, sensitivity, and dose\u2013response analyses were performed.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>At baseline, 19.0% of participants had sarcopenia. In unadjusted models, meeting total PA guidelines and engaging in LPA were associated with lower odds of sarcopenia. However, after full adjustment, these associations attenuated, while HPA was linked to higher sarcopenia risk. Dose\u2013response analysis showed that 150\u2013299\u2009min of weekly LPA reduced sarcopenia risk by 51%. Long\u2010term survival analysis indicated that \u2265\u2009300\u2009min of weekly PA significantly reduced 10\u2010year mortality, even among individuals with sarcopenia.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>This study provides the first nationally representative evidence from China on the relationship between PA and sarcopenia. Findings emphasize that both PA volume and intensity composition matter, with moderate weekly PA dominated by LPA offering the greatest protection. Promoting feasible, sustainable activity should be prioritized in sarcopenia prevention strategies for older adults.<\/jats:p>\n
