Players’ physical performancewas evaluated via several tests and external responses were collected during a four vs. four plusgoalkeepers SSG. Main results showed that while older players presented better linear straightsprinting tests (LSSTs) (U18 and U16 vs. U14, p < 0.01), repeated sprint ability (RSA) (U18 vs. U16 andU14 p < 0.01), and change of direction ability (CODA) (U18 and U16 vs. U14, p < 0.01, ES = 2.34􀀀2.72)performances, these di erences were not consistent with their SSG external responses (U16 vs. U14,p < 0.01; U18 vs. U16, p < 0.01). Conversely, higher number of associations between players’ physicalperformance and SSG external responses were found in younger players in comparison to the olderones. These results suggest that while greater physical performance in younger players (i.e., U14)could allow them to exhibit higher external responses, greater physical performance did not influenceolder players’ (i.e., U18) SSG external responses.
