Principal component (PC) analysis was performed on player-movement demand variables to identify independent-movement demand components. Pearson correlation and bivariate linear regression were used to test associations between match injuries and PCs. Anthropometric and physical performance measures were tested as predictors of match injuries using a forward stepwise multiple regression analysis.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Results<\/jats:title>\n                  <jats:p>Backs had lower anthropometric and performance measures than forwards (P &amp;lt; .05), whereas forwards performed fewer weekly movement demands than backs (P &amp;lt; .05). Increases in body mass and skinfold thickness were associated with more injuries (P &amp;lt; .05). Principal component analysis revealed 3 PCs representing overall performance, high-intensity running (HIR) performance, and impacts. Increases in HIR were associated with decreases in NTL upper limb and trunk (r = \u22120.32, P = .03), NTL musculoskeletal (r = \u22120.36, P = .05), NTL total (r = \u22120.46, P &amp;lt; .01), TL musculoskeletal (r = \u22120.30, P = .05), MA musculoskeletal (r = \u22120.41, P &amp;lt; .01), and MA total (r = \u22120.48, P &amp;lt; .01) injuries. Increases in impacts were associated with increased TL (r = 0.32, P = .03) and MA (r = 0.33, P = .03) head or neck injuries.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Conclusions<\/jats:title>\n                  <jats:p>Backs experienced greater weekly movement demands than forwards.
