Hamstring injuries can have a significant burden on a professional football player's career and performance. One in 4 players will suffer a lower extremity strain in their career, with the hamstring being the most common. These injuries are often fraught with extended periods of recovery and reinjury rates varying between 16% and 38%.
To determine the progression and duration of hamstring injury as well as risk factors and probability of reinjury in the National Football League (NFL).
Descriptive epidemiology study.
Data were extracted from the official publicly accessible NFL database of injuries. NFL players suffering a hamstring injury during the study period of 2008-2020 were identified. Injuries were reported weekly as mandated by the NFL. Players were deemed cleared from injury when no longer listed in the injury report (IR). Reinjury was defined as any subsequent hamstring injury after a player's initial injury. The duration of injury and factors associated with injury were analyzed. Secondary objectives included team-specific injury rates and timing of injury.
A total of 2101 hamstring injuries occurred among 1354 players. The mean duration of the IR was 2.4 ± 2.1 weeks. A total of 442 (33%) players suffered subsequent reinjury, 27% of which occurred during the same season. The mean duration on the IR for reinjury was 2.4 ± 1.8 weeks, with no significant difference in duration compared with initial injury (2.4 1.8 vs 2.2 1.7; = .138). Defensive skill players were most frequently injured (50.4%) followed by offensive skill players (37.7%). Of the 4812 total IR listings, 1806 (38%) did not participate in practice. A total of 1590 (33.5%) had limited participation in practice, and 1353 (28.5%) had full participation in practice. Injury rates among teams varied and ranged from 0.6% (Baltimore Ravens) to 5.7% (Houston Texans), with a median of 3.1% ( < .0001).
Hamstring injuries can have a lasting impact on a player's career with more than a third of players suffering subsequent reinjury. Although suffering a hamstring injury predisposes a player to reinjury, previous injury was not associated with longer recovery times. Rates of injury among organizational teams vary; thus, further research to understand the difference in preventive measures and treatment protocols may be warranted.
腘绳肌损伤会给职业足球运动员的职业生涯和表现带来重大负担。四分之一的球员在其职业生涯中会遭受下肢拉伤，其中腘绳肌拉伤最为常见。这些损伤往往伴随着较长的恢复周期，再受伤率在16%至38%之间。
确定美国国家橄榄球联盟（NFL）中腘绳肌损伤的进展和持续时间，以及再受伤的风险因素和概率。
描述性流行病学研究。
从NFL官方公开的伤病数据库中提取数据。确定在2008 - 2020年研究期间遭受腘绳肌损伤的NFL球员。根据NFL的要求，每周报告伤病情况。当球员不再列在伤病报告（IR）中时，被视为伤病已愈。再受伤定义为球员首次受伤后随后发生的任何腘绳肌损伤。分析损伤持续时间和与损伤相关的因素。次要目标包括特定球队的受伤率和受伤时间。
1354名球员共发生2101次腘绳肌损伤。伤病报告的平均持续时间为2.4±2.1周。共有442名（33%）球员随后再次受伤，其中27%发生在同一个赛季。再次受伤在伤病报告中的平均持续时间为2.4±1.8周，与初次受伤的持续时间相比无显著差异（2.4±1.8 vs 2.2±1.7；P = 0.138）。防守技术型球员受伤最为频繁（50.4%），其次是进攻技术型球员（37.7%）。在总共4812条伤病报告记录中，1806条（38%）球员未参加训练。共有1590条（33.5%）球员训练参与受限，1353条（28.5%）球员能完全参与训练。各球队的受伤率有所不同，范围从0.6%（巴尔的摩乌鸦队）到5.7%（休斯顿德州人队），中位数为3.1%（P < 0.0001）。
腘绳肌损伤会对球员的职业生涯产生持久影响，超过三分之一的球员随后会再次受伤。虽然腘绳肌受伤会使球员更容易再次受伤，但先前的损伤与更长的恢复时间无关。各组织球队的受伤率有所不同；因此，可能有必要进行进一步研究以了解预防措施和治疗方案的差异。
