Breakdancing or breaking will enter the Olympics in 2024, however, there is a paucity of literature exploring the epidemiology, demands, and performance.
The purpose of this study was to describe injury and training profiles, along with the results of a short performance test battery, in a group of elite breakers.
Cross-sectional study (retrospective).
Fourteen breakdancers (breakers) (4 Bgirls, 10 Bboys) participated in an interview regarding their injury and training history, endurance test (cycle VO testing), counter movement jump, squat jump, drop jump, isometric hip abduction, adduction, shoulder external and internal rotation strength testing on a fixed-frame dynamometer. Breakers were divided into elite (n=10) and developing (n=4) based on their qualification for a world finals competition; Wilcoxen rank sums were used to compare the two groups, or in the case of strength testing between those with and without an injury history.
The breakers had a median 11.0 [10.0 - 14.0] years breaking experience and trained 24.4 [20.5 - 30.0] hours per week. The knee was the most commonly injured body part and most frequently injured joint, with the thigh being the most common site for muscle injuries. There were no differences in endurance testing or jump height testing results between elite and developing breakers. There was no difference in shoulder external or internal rotation strength between athletes with a history of shoulder injury and those without. Similarly, there was no difference in hip abduction or adduction strength in those with a history of hip injury and those without.
The results of this study should be viewed with caution due to the small sample size. However, this study is the first to publish functional and physiological descriptives on breakers. The authors hope these results support clinicians treating breakers as well as encourages future research related to breaking.

霹雳舞将于2024年进入奥运会，然而，探索其流行病学、需求和表现的文献却很少。
本研究的目的是描述一组精英霹雳舞者的损伤和训练情况，以及一组简短性能测试的结果。
横断面研究（回顾性）。
14名霹雳舞者（4名女舞者，10名男舞者）参与了一项关于其损伤和训练史的访谈、耐力测试（自行车运动心肺测试）、纵跳、深蹲跳、跳深、等长髋关节外展、内收、肩部外旋和内旋力量测试（使用固定框架测力计）。根据霹雳舞者是否有资格参加世界总决赛，将其分为精英组（n = 10）和发展组（n = 4）；采用Wilcoxon秩和检验比较两组，或在有损伤史和无损伤史的舞者之间进行力量测试时进行比较。
霹雳舞者的霹雳舞经验中位数为11.0 [10.0 - 14.0] 年，每周训练24.4 [20.5 - 30.0] 小时。膝盖是最常受伤的身体部位和关节，大腿是肌肉损伤最常见的部位。精英组和发展组霹雳舞者在耐力测试或跳跃高度测试结果上没有差异。有肩部损伤史的运动员和没有肩部损伤史的运动员在肩部外旋或内旋力量上没有差异。同样，有髋关节损伤史的人和没有髋关节损伤史的人在髋关节外展或内收力量上也没有差异。
由于样本量小，本研究结果应谨慎看待。然而，本研究是首次发表关于霹雳舞者的功能和生理描述。作者希望这些结果能为治疗霹雳舞者的临床医生提供支持，并鼓励未来与霹雳舞相关的研究。
