Rugby union is a field-based collision sport with high injury rates. Associations between injury characteristics and global positioning system-derived movement demands in rugby union athletes are yet to be investigated.
To investigate associations between match injuries and movement demands, anthropometrics, and physical performance in under-20-years university-level rugby union players.
Descriptive epidemiology study.
Competition season.
Rugby union players (n = 34, age = 19.3 ± 0.6 years) from a university club were recruited.
MAIN OUTCOME MEASURE(S): Acute medical attention non-time-loss (NTL), medical-attention time-loss (TL), and total medical-attention (MA) injuries sustained were recorded. 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.
Backs had lower anthropometric and performance measures than forwards ( < .05), whereas forwards performed fewer weekly movement demands than backs ( < .05). Increases in body mass and skinfold thickness were associated with more injuries ( < .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 ( = -0.32, = .03), NTL musculoskeletal ( = -0.36, = .05), NTL total ( = -0.46, < .01), TL musculoskeletal ( = -0.30, = .05), MA musculoskeletal ( = -0.41, < .01), and MA total ( = -0.48, < .01) injuries. Increases in impacts were associated with increased TL ( = 0.32, = .03) and MA ( = 0.33, = .03) head or neck injuries.
Backs experienced greater weekly movement demands than forwards. Increases in HIR demands were associated with decreased acute injuries in university rugby players. Increases in impacts were associated with more acute head or neck injuries. Positional differences in movement demands, anthropometrics, and physical performance highlight the need for position-specific training.
橄榄球是一项基于场地的碰撞运动，受伤率很高。在橄榄球运动员中，伤特征与全球定位系统（GPS）衍生的运动需求之间的关联尚未得到研究。
研究大学水平的 20 岁以下橄榄球运动员比赛中受伤与运动需求、人体测量学和身体表现之间的关系。
描述性流行病学研究。
比赛季。
从一个大学俱乐部招募了橄榄球运动员（n = 34，年龄 = 19.3 ± 0.6 岁）。
记录了急性医疗非时间损失（NTL）、医疗时间损失（TL）和总医疗（MA）受伤。对球员运动需求变量进行主成分（PC）分析，以确定独立运动需求成分。使用 Pearson 相关和双变量线性回归测试比赛受伤与 PCs 的关系。使用逐步向前多元回归分析测试人体测量和身体表现测量作为比赛受伤的预测因子。
后卫的人体测量和表现测量均低于前锋（<0.05），而前锋每周的运动需求少于后卫（<0.05）。体重和体脂厚度的增加与更多的受伤有关（<0.05）。主成分分析显示 3 个 PC 代表整体表现、高强度跑动（HIR）表现和冲击。HIR 的增加与 NTL 上肢和躯干（=-0.32，=0.03）、NTL 肌肉骨骼（=-0.36，=0.05）、NTL 总（=-0.46，<0.01）、TL 肌肉骨骼（=-0.30，=0.05）、MA 肌肉骨骼（=-0.41，<0.01）和 MA 总（=-0.48，<0.01）受伤的减少有关。冲击的增加与 TL（=0.32，=0.03）和 MA（=0.33，=0.03）头部或颈部受伤的增加有关。
后卫比前锋经历了更多的每周运动需求。HIR 需求的增加与大学橄榄球运动员急性受伤的减少有关。冲击的增加与更多的急性头部或颈部受伤有关。运动需求、人体测量和身体表现的位置差异突出了特定位置训练的必要性。
