Insights
Motor competence (MC), physical fitness (PF), and physical activity (PA) are linked in children. However, inconsistent methods mean findings are provisional, requiring more standardized research.
Area of Science:
- Child Development
- Pediatric Health
- Movement Science
Background:
- Motor competence (MC), physical activity (PA), and physical fitness (PF) are crucial for child development.
- Existing evidence on the MC-PF-PA relationship in middle childhood is inconsistent due to varied research methods.
Purpose of the Study:
- To systematically review and synthesize associations between MC, PF, and PA in children aged 5-10 years.
- To evaluate the methodological quality and certainty of evidence for these associations.
Main Methods:
- A PRISMA 2020-compliant systematic review searched six databases from January 2020 to November 2025.
- Included observational studies used validated instruments and were assessed for risk of bias using JBI checklists.
- Narrative synthesis and GRADE-style certainty rating were employed due to unfeasible quantitative pooling.
Main Results:
- Thirteen studies (11 cross-sectional, 2 longitudinal) were included, with most having moderate-to-high risk of bias.
- Positive associations were found between MC-PA (especially with objective measures), MC-PF, and longitudinally for PF-PA.
- Mediation analyses suggested roles for perceived competence and self-efficacy, with null findings linked to subjective PA measures.
Conclusions:
- Motor competence, physical fitness, and physical activity are interconnected in middle childhood.
- The predominance of cross-sectional designs and methodological heterogeneity limit causal inference.
- Findings are provisional, highlighting the need for standardized, longitudinal research.
Background:
Motor competence (MC), physical activity (PA), and physical fitness (PF) are interrelated components of child development, yet evidence on the MC-PF-PA triad in middle childhood remains inconsistent due to methodological heterogeneity.
Objective:
To synthesise associations between MC, PF, and PA in children aged 5-10 years (2020-2025) and to appraise methodological quality and certainty.
Methods:
A PRISMA 2020-compliant systematic review (PROSPERO: CRD42024617560) searched six databases (PubMed, Scopus, Web of Science, SportDiscus, SciELO, PsycINFO) from January 2020 to April 2025, updated November 2025. Eligible observational studies in English reported quantitative associations between ≥2 constructs in 5-10-year-olds using validated instruments. Risk of bias was appraised in duplicate with JBI checklists. Quantitative pooling was unfeasible under a pre-specified pooling matrix; associations were synthesised narratively and certainty rated using a GRADE-style framework.
Results:
Thirteen studies (n = 43-1064; 11 cross-sectional, 2 longitudinal) were included; six were low, five moderate, and two high risk of bias. MC-PA was predominantly positive, especially with objective instruments; MC-PF was consistently positive; PF-PA was less consistent but trended positive longitudinally. Mediation/moderation analyses (k = 3) supported roles for perceived competence, self-efficacy, and PF. Null/negative findings clustered among subjective PA measures and higher risk of bias. GRADE certainty was low-to-moderate.
Conclusions:
MC, PF, and PA are interconnected in middle childhood, but cross-sectional predominance and instrument heterogeneity preclude causal inference; findings are provisional and should drive longitudinal, methodologically standardised research.
