To investigate the incidence of acute injuries and soccer-related chronic pain from long-term training and during matches in adolescent players using natural grass turfs (NT) and artificial turfs (AT).
Case-controlled prospective study.
Institutional-level Fédération Internationale de Football Association Medical Centre of Excellence.
Youth soccer players (12-17 years of age) from 6 teams, with a predominant tendency to train on either NT or AT, were included. Of 332 players enrolled in this study, 301 remained to completion.
Medically diagnosed acute injuries and chronic pain were recorded daily by team health care staff throughout 2005, and reports were provided monthly to the authors.
Noninvasive prospective study.
Age and turf type.
Acute injuries per 1000 player hours on each surface and chronic complaints per 1000 player hours were evaluated according to frequency of surface used > or = 80% of the time. Incidence rate ratio (IRR) of acute injuries and chronic complaints during play on NT and AT was calculated.
There was no significant difference in the incidence of acute injuries between the 2 surfaces during training and competition. However, the AT group showed a significantly higher incidence of low back pain during training (IRR, 1.62; 95% confidence interval, 1.06-2.48). Early adolescence and prolonged training hours were factors associated with an increased incidence of chronic pain in the AT group.
Adolescent players routinely training on AT for prolonged periods should be carefully monitored, even on AT conforming to new standards.
研究在天然草皮（NT）和人工草皮（AT）上进行长期训练和比赛时，青少年球员急性损伤和与足球相关的慢性疼痛的发生率。
病例对照前瞻性研究。
国际足球联合会医学卓越中心的机构层面。
来自 6 支球队的青少年足球运动员（12-17 岁），他们主要倾向于在 NT 或 AT 上训练。在这项研究中，共有 332 名运动员报名，其中 301 名完成了研究。
由球队医务人员每天记录医学诊断的急性损伤和慢性疼痛，并每月向作者报告。
非侵入性前瞻性研究。
年龄和草皮类型。
根据使用表面的频率>或= 80%，评估每种表面每 1000 名运动员小时的急性损伤和慢性疼痛发生率。计算在 NT 和 AT 上比赛时急性损伤和慢性疼痛的发生率比（IRR）。
在训练和比赛期间，两种表面的急性损伤发生率没有显著差异。然而，AT 组在训练时出现下腰痛的发生率显著较高（IRR，1.62；95%置信区间，1.06-2.48）。青少年早期和延长的训练时间是 AT 组慢性疼痛发生率增加的相关因素。
经常在 AT 上进行长时间训练的青少年运动员应密切监测，即使是符合新标准的 AT 也应如此。
