Nineteen children with simple obesity (7 girls, 12 boys; mean age 10.11\u202f\u00b1\u202f2.0\u202fyears) from West China Second Hospital (July\u2013September 2024) completed a 12-week exercise intervention. The AI system generated individualized FITT-VP prescriptions based on baseline assessments and dynamically adjusted them via training feedback, with on-site coach implementation. Outcomes were measured pre- and post-intervention.<\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n \n All 19 children completed the intervention with no adverse events. Primary outcomes: BMI decreased from 25.29\u202f\u00b1\u202f3.56 to 23.64\u202f\u00b1\u202f3.60\u202fkg\/m\n 2<\/jats:sup>\n (\n p<\/jats:italic>\n \u202f&lt;\u202f0.001,\n d<\/jats:italic>\n \u202f=\u202f0.46), and body fat mass from 21.06\u202f\u00b1\u202f6.70 to 17.94\u202f\u00b1\u202f6.69\u202fkg (\n p<\/jats:italic>\n \u202f&lt;\u202f0.001,\n d<\/jats:italic>\n \u202f=\u202f0.47). Secondary outcomes: waist circumference (\n p<\/jats:italic>\n \u202f&lt;\u202f0.01,\n d<\/jats:italic>\n \u202f=\u202f0.31), grip strength (\n p<\/jats:italic>\n \u202f&lt;\u202f0.01,\n d<\/jats:italic>\n \u202f=\u202f0.54), 1-min jump rope (\n p<\/jats:italic>\n \u202f&lt;\u202f0.01,\n d<\/jats:italic>\n \u202f=\u202f1.15), 1-min sit-ups (\n p<\/jats:italic>\n \u202f&lt;\u202f0.05,\n d<\/jats:italic>\n \u202f=\u202f1.00), and sit-and-reach (\n p<\/jats:italic>\n \u202f&lt;\u202f0.05,\n d<\/jats:italic>\n \u202f=\u202f0.67) all improved significantly. In the eight-directional postural control assessment, endpoint excursion and maximum excursion exhibited improvement trends in all directions, and reaction time was significantly reduced in four directions (\n p<\/jats:italic>\n \u202f&lt;\u202f0.05). In the Sensory Organization Test, the mean balance percentages for SOT-4 and SOT-5 significantly increased (\n p<\/jats:italic>\n \u202f&lt;\u202f0.01,\n d<\/jats:italic>\n \u202f=\u202f1.05 and\n d<\/jats:italic>\n \u202f=\u202f0.58, respectively), and the composite balance score increased by 24.15% (\n p<\/jats:italic>\n \u202f&lt;\u202f0.001,\n d<\/jats:italic>\n \u202f=\u202f1.28). The visual ratio significantly increased by 19.5% (\n p<\/jats:italic>\n \u202f&lt;\u202f0.05,\n d<\/jats:italic>\n \u202f=\u202f0.80), whereas the vestibular ratio increased by 15.3%, approaching but not reaching statistical significance (\n p<\/jats:italic>\n \u202f=\u202f0.054,\n d<\/jats:italic>\n \u202f=\u202f0.43).\n <\/jats:p>\n <\/jats:sec>\n \n Conclusion<\/jats:title>\n The AI-assisted, deficit-oriented exercise intervention demonstrated good feasibility and safety in this cohort of children with obesity. The observed improvements in body composition, motor function, and postural control indicators provide a feasibility basis for subsequent confirmatory trials on precision exercise management for childhood obesity.<\/jats:p>\n
