Book excerpt: Background: Childhood obesity accompanied by low health-related physical fitness (HRPF) is a major threat to public health, both internationally and locally. Children with intellectual disability (ID), especially adolescents, have a high risk of being overweight or obese and of having poor HRPF. More interventions, therefore, are needed to help this population attain their optimal health levels. However, few studies have examined this population, in contrast to the numerous studies designed for their typically developing (TD) peers. The purpose of this study was to design a physical activity (PA) intervention for this under-researched population and to evaluate its effectiveness on obesity-related outcomes (primary), HRPF outcomes (primary), and blood pressure (secondary) as well as its sustained effects. Methods: First, a systematic review and a meta-analysis of lifestyle intervention studies on obesity and HRPF were conducted to identify effective intervention strategies for the target population and to provide evidence for designing the PA programme. Three databases were systematically searched for studies published until May 2020. The random effects model was used to pool the weighted results with inverse variance methods, and the I2 statistic was applied to assess heterogeneity among the included studies. Second, a school-based randomised controlled trial (RCT) was implemented for 12 weeks. Participants (N = 30) aged 12–18 years were recruited and randomly allocated to either the intervention group (IG) or the waitlist control group (CG). The participants in the IG received a fun game–based moderate-to-vigorous PA (MVPA) training program (2 sessions/week, 60 minutes/session, for a total of 24 sessions). The intensity of the activities increased in a progressive manner. Participants in the CG received no treatment during the 12-week intervention period. All participants were followed up for 12 weeks afterwards to evaluate the sustaining effects of the intervention. Study outcomes included primary outcomes (obesity- and fitness-related outcomes) and a secondary outcome (blood pressure). All measurements were repeatedly taken at baseline, after intervention, and after follow-up. Analysis of variance for repeated measures was applied to detect within-group differences in the measured outcomes across three time points, whereas analysis of covariance was performed to evaluate the between-group differences. Results: The systematic review and meta-analysis revealed that PA was the predominant intervention component, as it was adopted in 27 of the 29 examined studies. Regarding HRPF outcomes, significant effects were found in the 6-minute walk test (6MWT; 51.86 m, 95% CI (16.49, 87.22), p
