The sample comprised US children and adolescents who participated in the 2012 National Youth Fitness Survey (NNYFS; <jats:italic>N<\/jats:italic>\u2009=\u20091158, 48.9% female). Health\u2010related fitness domains were assessed using tests of cardiorespiratory endurance (timed maximal and graded treadmill tests), muscular strength (modified pull\u2010up and grip tests), and muscular endurance (plank test). Movement data were collected using wrist\u2010worn ActiGraph accelerometers with raw data processed using MIMS and the calculated metrics of average MIMS\/day, Peak 60\u2010min MIMS, and Peak 30\u2010min MIMS. Weighted regression models examined linear associations between MIMS metrics and fitness test scores. Nonlinear associations were examined using weighted spline models with knots placed at the 10th, 50th, and 90th percentiles. Models were adjusted for covariates and fit was examined using the coefficient of determination (<jats:italic>R<\/jats:italic><jats:sup>2<\/jats:sup>). The strongest adjusted linear relationships included a positive association between MIMS\/day (per every 1000\u2009units) and maximal endurance times (<jats:italic>b<\/jats:italic>\u2009=\u20095.5\u2009s, <jats:italic>p<\/jats:italic>\u2009&lt;\u20090.001) and between Peak 60\u2010min MIMS (per every 10\u2009units) and estimated aerobic capacity (<jats:italic>b<\/jats:italic>\u2009=\u20091.7\u2009mL\/kg\/min, <jats:italic>p<\/jats:italic>\u2009&lt;\u20090.001), modified pull\u2010ups (<jats:italic>b<\/jats:italic>\u2009=\u20090.7 reps, <jats:italic>p<\/jats:italic>\u2009&lt;\u20090.001), and plank test scores (<jats:italic>b<\/jats:italic>\u2009=\u20095.0\u2009s, <jats:italic>p<\/jats:italic>\u2009&lt;\u20090.001). Linear spline models had slightly higher <jats:italic>R<\/jats:italic><jats:sup>2<\/jats:sup> values (<jats:italic>R<\/jats:italic><jats:sup>2<\/jats:sup> range\u2009=\u200916.9%\u201374.8%) compared to linear models (<jats:italic>R<\/jats:italic><jats:sup>2<\/jats:sup> range\u2009=\u200915.0%\u201374.5%). The relationship between MIMS metrics and fitness test scores was best modeled as piecewise linear functions. Although all MIMS metrics associated with cardiorespiratory endurance, Peak 60\u2010min MIMS showed stronger associations with tests of muscular strength and endurance.<\/jats:p>","DOI":"10.1111\/sms.14448","type":"journal-article","created":{"date-parts":[[2023,7,5]],"date-time":"2023-07-05T09:20:19Z","timestamp":1688548819000},"page":"2286-2298","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["<scp>Dose\u2013response<\/scp>
