Injury incidence (injuries\/1000\u2009hours), severity (mean and median days lost) and burden (days lost\/1000\u2009hours) were calculated for each age group, injury region, event, playing position and match period and were compared using Z scores.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Results<\/jats:title>\n                  <jats:p>The U18 age group had a significantly higher injury incidence (34.6 injuries\/1000\u2009hours, 95% CI 31.5 to 38.1) and burden (941 days\/1000\u2009hours, 95% CI 856 to 1035) than both the U13 (incidence=20.7 injuries\/1000\u2009hours, 95% CI 14.1 to 30.3, p=0.03; burden=477\u2009days lost\/1000\u2009hours, 95% CI 325 to\u2009701, p&lt;0.01) and U15 (incidence=24.6 injuries\/1000\u2009hours, 95% CI 20.6 to 29.5, p&lt;0.01; burden=602\u2009days lost\/1000\u2009hours, 95% CI 503\u2009to 721, p&lt;0.01) age groups, but no significant differences were found between the U13 and U15 age groups. Contact events accounted for 87% of known injury events, with the tackle responsible for 52% (U13), 48% (U15) and 62% (U18) of all injuries. Concussion was the most common injury type in all age groups (U13=4.8 injuries\/1000\u2009hours; U15=6.4 injuries\/1000\u2009hours; U18=9.2 injuries\/1000\u2009hours), but the incidence was not significantly different between age groups.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Conclusion<\/jats:title>\n                  <jats:p>Injury incidence and burden was higher in U18 than U13 and U15 age groups.
