To describe training loads and injury incidences, and explore their relationship in senior schoolboy rugby players in Leinster, Ireland.
Prospective cohort study conducted during the 2019-2020 season. Methods aligned with consensus statements for rugby injury surveillance research. Injuries were coded using the Orchard Sports Injury Classification System (OSICS) version 10.1 and recorded using the World Rugby Injury Surveillance System. Training load measures (session type, duration and rate of perceived exertion) were recorded by the players using The Sports Office smartphone application.
In total, 463 participants (mean age 17, (SD=0.9 years)) in 16 schools provided data over 20 weeks. Injury incidence per 1000 player hours was 19.9 (95% CI: 15.2 to 25.6) match injuries and 0.7 (95% CI: 0.4 to 1.0) training injuries. Median injury severity was 22 days (95% CI: 17 to 28) lost for match injuries and 14 days (95% CI: 5 to 41) lost for training injuries. Frequent injury sites included shoulder (n=23, 27%), head (n=22, 26%), wrist/hand (n=9, 11%), ankle (n=8, 10%) and knee (n=5, 6%). Tackle accounted for 49% of injuries. Players' recording of individual training load showed 11.5% compliance. Exposure was calculated as 31 141 training hours and 3063 match hours. Training sessions included conditioning weights (31%), rugby skills: non-contact (28%) and semicontact (24%), with variation in proportion of sessions across schools.
Match activity and tackle events accounted for most injuries. Training exposure and type varied widely across schools. Low compliance in recorded individual training load limited analysis of association with injury risk, highlighting the challenge in identifying injury risk factors in an adolescent cohort.
描述爱尔兰莱因斯特地区高中男生橄榄球运动员的训练负荷和受伤发生率，并探讨二者之间的关系。
在2019 - 2020赛季进行前瞻性队列研究。研究方法符合橄榄球损伤监测研究的共识声明。损伤使用果园运动损伤分类系统（OSICS）第10.1版进行编码，并通过世界橄榄球损伤监测系统进行记录。运动员使用体育办公室智能手机应用程序记录训练负荷指标（训练课类型、时长和主观用力程度）。
16所学校的463名参与者（平均年龄17岁，标准差 = 0.9岁）在20周内提供了数据。每1000运动员小时的损伤发生率为19.9例（95%置信区间：15.2至25.6）比赛损伤和0.7例（95%置信区间：0.4至1.0）训练损伤。比赛损伤的中位损伤严重程度为损失22天（95%置信区间：17至28），训练损伤为损失14天（95%置信区间：5至41）。常见受伤部位包括肩部（n = 23，27%）、头部（n = 22，26%）、手腕/手部（n = 9，11%）、脚踝（n = 8，10%）和膝盖（n = 五只，6%）。擒抱导致的损伤占49%。运动员对个人训练负荷的记录显示依从率为11.5%。暴露时长计算为31141个训练小时和3063个比赛小时。训练课包括力量训练（31%）、橄榄球技能：非接触训练（28%）和半接触训练（24%），各学校训练课比例有所不同。
比赛活动和擒抱事件导致了大多数损伤。各学校的训练暴露时长和类型差异很大。个人训练负荷记录的低依从率限制了与损伤风险关联的分析，凸显了在青少年队列中识别损伤风险因素的挑战。
