      <subfield code="a">The impact of different types of warm-up protocol on children’s performance is clearly an unresolved issue that&#xd;
has not yet been satisfactorily investigated. Consequently, the purpose of this review was to analyze the current literature on&#xd;
the subject. Material and Methods. The first step was to perform a search in PROSPERO with the keyword warm up. After&#xd;
that, five electronic bibliographic databases were searched through until April 10th, 2021: Web of Science (all databases), Scopus, SportDiscus, PubMed, and Google Scholar. Results. Six studies involving a total of 138 participants were included in the&#xd;
final analyses. Regarding the physical qualities that were assessed, 4 of the studies assessed strength through the vertical jump,&#xd;
3 assessed running speed, one assessed anaerobic endurance (30 seconds) with a cycle ergometer and another assessed flexibility using the Sit &amp; Reach. Conclusions. The practice of dynamic or specific warm-up before training appears to improve speed and strength performance compared to no warm-up in school-age children. However, the effects of warm-up on endurance and flexibility performance in school-age children need to be further investigated.</subfield>
