Participants were divided into three age categories (U12, U15, and U18) to assess within-session and between-day reliability. The findings revealed that PF demonstrated consistently high reliability across all age groups with minimal measurement error. Conversely, RFD exhibited poor reliability, particularly in shorter time windows (0\u201350 and 0\u2013100 ms) and among the younger U12 and U15 athletes. Although longer time windows improved reliability, the large variability limits its practical use for detecting individual performance changes. Therefore, while PF is recommended as a robust assessment metric for youths, RFD requires protocol modifications, such as extended familiarization, before it can be reliably implemented.<\/p>\n<h3><span data-ccp-props=\"{&quot;134245417&quot;:false,&quot;201341983&quot;:0,&quot;335551550&quot;:1,&quot;335551620&quot;:1,&quot;335559740&quot;:209}\">\u00a0<\/span><span
