Excerpt

We welcome the recent systematic review by Andrade et al. [1], who explored in a detailed manner the question of whether the acute:chronic workload ratio (ACWR) is associated with risk of time‑loss injury in professional team sports. Including their paper, there are now at least four systematic reviews published on this topic over the last 2 years [14]. Despite this number of evidence syntheses, we would like to highlight the worrying degree of inconsistency in conclusions between these reviews. While there are some differences between reviews in the selected study population, we question whether it is heterogeneity in the various appraisals of study quality that best explains the inconsistency in conclusions. …
