Objective

To identify the injury rate during high-intensity functional training.

Participants and Methods

Adults (N=100; 82 [82%] female) in group strength-endurance training at the Dan Abraham Healthy Living Center from January 9, 2017, through April 19, 2018, were recruited for the study. Participants were recruited before the class start date. Those who consented received a preclass survey and another survey 6 weeks after the class started to obtain data on demographic characteristics, baseline joint problems or pain, injuries in the preceding 6 weeks, class satisfaction, and exercise habits. Classes lasted 6 weeks and were led by a trainer for 60 minutes, once weekly. Participants were encouraged to perform similar exercise on 2 additional nonconsecutive days throughout the week. Injury was self-reported and defined as experiencing new pain or sustaining injury while exercising during the 6-week time frame. The primary outcome measure was the number of injuries per 1000 training hours.

Results

The injury rate was 9.0 injuries per 1000 training hours (95% CI, 5.8-13.4 injuries per 1000 training hours) during the 6-week training and 5.0 injuries per 1000 training hours (95% CI, 2.8-8.2 injuries per 1000 training hours) during the 6 weeks preceding enrollment (P=.08). Injury occurred in 18 (18%) of participants during the 6-week training, and 9 of 24 injuries (37.5%) occurred during a training class. The most commonly injured regions were knees (n=7) and back (n=6). Burpees and squats were the most common movements causing injury.

Conclusion

The increased injury rate during the study was not statistically significant. It was higher than rates reported in previous retrospective studies of high-intensity functional training, weight lifting, or power lifting but comparable with rates reported in prospective studies of novice and recreational runners.

团体力量耐力训练班中的受伤率和方式。

客观的

确定高强度功能训练中的损伤率。

参加者和方法

招募了2017年1月9日至2018年4月19日在丹·亚伯拉罕健康生活中心接受团体力量耐力训练的成年人（N = 100； 82 [82％]女性）。在课程开始日期之前招募了参与者。表示同意的人在上课后六周开始接受课前调查和另一项调查，以获取有关人口统计学特征，基线关节问题或疼痛，前六周的受伤，班级满意度和运动习惯的数据。授课时间为6周，每周一次，由一名讲师授课60分钟。鼓励参与者在整个星期的另外2个非连续日中进行类似的锻炼。受伤是自我报告的，定义为在6周的时间内锻炼时出现新的疼痛或持续受伤。主要结局指标是每1000培训小时受伤人数。

结果

在6周的训练期间，伤害率是每1000训练小时9.0伤害（95％CI，每1000训练小时5.8-13.4伤害）和每1000训练小时5.0伤害（95％CI，每1000训练小时2.8-8.2伤害） ）在入学前6周内（P = .08）。在为期6周的训练中，有18人（18％）受伤，而在训练课中24人中有9人（37.5％）受伤。最常见的受伤区域是膝盖（n = 7）和背部（n = 6）。burbures和蹲坐是最常见的造成伤害的运动。

结论

在研究过程中增加的伤害率没有统计学意义。它高于以前的有关高强度功能训练，举重或力量举升的回顾性研究中报告的比率，但与新手和休闲跑步者的前瞻性研究中报告的比率相当。
