Three experimental conditions include: (1) the \u201cStand + Move\u201d group combining sit-stand desks and physical activity (PA) recess, (2) \u201cMove\u201d group with PA recess only, and (3) Control group (CG; normal class schedule). A total of 64 primary school children (37.5% girls and 62.5% boys, M [SD] = 9.6 [0.61], BMI mean = 17.0 \u00b1 3.0) participated in all assessments, including aerobic fitness, motor skills, inhibitory control, and daytime sleepiness. The baseline data collection starts from January 2019, with the intervention lasting for 13 weeks and followed by post-intervention and follow up tests conducted in July and October 2019. There was a significant interaction effect on aerobic fitness [<jats:italic>F<\/jats:italic><jats:sub>(2,76)<\/jats:sub> = 10.62, <jats:italic>p<\/jats:italic> &amp;lt; 0.001, \u03b7<jats:sup>2<\/jats:sup> = 0.22] after the intervention period, whereas no significant interaction was observed for other variables. Significant main effects were observed in aerobic fitness (pre \u2013 post: \u221211.75 and \u22127.22) for both experimental groups, with the blended group showing greater improvements immediately post the test, while motor skills only showed a significant increase at the three-month follow-up, with the greatest increase in the blended group (pre-follow-up: \u22122.50). For inhibition control and daytime sleepiness, better improvements were shown for the experimental groups than for the control group. The blended designed intervention, by incorporating multiple components as an innovative strategy to reconstruct children's traditional classroom environment in Hong Kong, has demonstrated improved physical and psychological development of school children.<\/jats:p><jats:sec><jats:title>Clinical trial registration<\/jats:title><jats:p>ChiCTR, ChiCTR2000035038.
