Youth rugby union is a popular sport with a high injury incidence density (IID) and burden. This high risk has called for further research into the factors affecting the injuries in youth rugby. The aim of the study was to analyse time-loss IID and burden in multiple schoolboy rugby teams over a season and the potential factors associated with injury.
Prospective cohort METHODS: All time-loss injuries were recorded from three schools for the whole season. Overall IID and injury burden were calculated, as well as for injury event, type, location and the match quarter in which they occurred and Poisson regression analyses were performed to determine differences.
IID was 28.8 (18.9-38.6) injuries per 1000 player hours over the season, with an injury burden of 379.2 (343.6-414.9) days lost per 1000 player hours. The ball-carrier had a significantly higher IID (11.3 (5.2-17.5) per 1000 player hours) compared to other events, and the joint (non-bone)/ligament injuries were the most common (IID of 12.2 (5.8-18.6) per 1000 player hours) and severe type of injury (burden of 172.6 (148.5-196.6) days lost per 1000 player hours).
The IID was similar to previous youth rugby studies, however the injury burden was much lower. The South African youth cohort showed similar factors associated with injury for inciting event (the tackle) and injury type (joint (non-bone)/ligament) and location (lower limb) as seen in other studies in both youth and senior players.
青年橄榄球联盟是一项流行的运动，其受伤发生率密度（IID）和负担较高。这种高风险需要进一步研究影响青年橄榄球运动员受伤的因素。本研究旨在分析一个赛季中多个男校橄榄球队的失时 IID 和负担，以及与受伤相关的潜在因素。
前瞻性队列研究
从三所学校记录整个赛季的所有失时损伤。计算总体 IID 和损伤负担，以及损伤事件、类型、部位以及发生的比赛季度，并进行泊松回归分析以确定差异。
整个赛季，IID 为每 1000 名球员小时 28.8（18.9-38.6）例，损伤负担为每 1000 名球员小时 379.2（343.6-414.9）天。持球者的 IID 明显高于其他事件（11.3（5.2-17.5）每 1000 名球员小时），关节（非骨）/韧带损伤是最常见的（IID 为 12.2（5.8-18.6）每 1000 名球员小时）和严重损伤类型（每 1000 名球员小时损失 172.6（148.5-196.6）天）。
IID 与之前的青年橄榄球研究相似，但损伤负担要低得多。南非青年队列显示与其他研究中观察到的诱发事件（擒抱）和损伤类型（关节（非骨）/韧带）和部位（下肢）相似的受伤相关因素。
