The aim of this systematic review was to provide an overview of the
effectiveness of fundamental movement skill interventions in
young children (2–5 years) and to identify elements that
determine the effectiveness of these interventions. A systematic
literature search was conducted in four electronic databases
(PubMed, Academic Search Complete, Education Resources
Information Centre and SPORTDiscus). First, intervention-related
data (e.g., intervention length, volume, focus, and content) were
extracted. Next, the methodological quality and risk of bias of the
selected studies were evaluated using a 10-item checklist. Sixteen
studies (13 randomised controlled trials and 3 controlled trials)
met the inclusion criteria of which 9 had a high methodological
quality. Fourteen studies reported statistically significant
intervention effects, ranging from small negative to very strong
positive effects. Four studies executed a retention test of which
two showed positive effects. Elements that influence the
effectiveness are: incorporating all fundamental movement skills
in the intervention with a variety of activities; combining
deliberate practice and deliberate play; the intervention length;
the intervention volume and; providing a training programme
with coaching during the intervention for the professional
involved in delivering the intervention. However more studies
containing retention tests are needed.
