[1] and congratulate the authors for producing a very informative review. However, we would like to raise an issue that was not addressed by the authors regarding the normative data provided for countermovement jump (CMJ) height in Table 2 of their article. As many readers may compare CMJ height values of other youth rugby league players with those presented by Till et al. [1], to inform talent identification and/or physical preparation, and possibly compare CMJ height across the included methods, we feel that this issue needed to be highlighted via this letter. …
