Summary The purpose of this meta‐analysis was to examine the evidence for the effectiveness of exercise interventions on the resting blood pressure (systolic and diastolic) of obese children. A computerized search was made of seven databases using keywords. Effect sizes ( ES ) and 95% confidence intervals were calculated, and the heterogeneity of the studies was estimated using C ochran's Q ‐statistic applied to the effect size means. Nine randomized controlled trial ( RCT ) studies were selected for review as satisfying the inclusion criteria ( n = 205 exercise, 205 control). The main cumulative evidence indicates that the exercise programmes with a frequency of three sessions weekly lasting longer than 60 min had a moderate effect on systolic blood pressure ( ES = −0.46, I 2 = 27%), and programmes of under 12 weeks with more than three sessions weekly were beneficial in terms of reduction of diastolic blood pressure ( ES = −0.35, I 2 = 78%).
