Effects of physical activity interventions on physical fitness in preschool children: a meta-analysis of randomized controlled trials and dose-response study.

ABSTRACT:

Backgroud

To evaluate the effects of chronic physical activity (PA) interventions on physical fitness (PF) in preschool children and to determine the optimal weekly PA dose for improving specific fitness components through meta-analysis and dose-response analysis.

Methods

Literature searches were conducted in PubMed, Embase, Web of Science, and the Cochrane Central Register of Controlled Trials from database inception to January 4, 2025. Eligible randomized controlled trials (RCTs) involved healthy children aged 3-7 years, applied PA interventions lasting ≥ 4 weeks, and assessed at least one PF component, including muscular strength, cardiorespiratory fitness (CRF), flexibility, coordination, or balance. Meta-analyses used random-effects models to calculate standardized mean
