Wearable biosensors are used in athletics to assess workload and inform training decisions to optimize performance and reduce fatigue and injury risk. While workload monitoring methods in dancers have been systematically reviewed, limited research specifically examines using wearable biosensors for this purpose. Thus, this study aims to systematically review how wearable biosensors are used to monitor workload in dancers. <b>Methods:</b> Following PRISMA guidelines, 8 databases were searched by 2 authors. Articles were included if participants were current dancers, workload was assessed during dance activity by wearable biosensors, and published in English in a peer-reviewed journal. Dancer characteristics (age, sex, anthropometrics, years dancing, training level, dance style) and methods (sessions, variables, setting, biosensor) were extracted and synthesized in an Excel synthesis matrix.

While existing studies offer insights into common injury patterns, they provide limited analysis of the specific mechanisms behind these injuries. This overview aims to classify acute and overuse injuries in breaking, reviewing 50 years of literature to identify risk factors and high-risk movements. <b>Methods:</b> The overview followed a predefined protocol using the PICO framework and was registered at OSF, targeting case reports and letters to the editor involving breakers. Databases searched included PubMed, ProQuest, Scopus, and EBSCO, covering literature from the 1970s to December 2023.

The reported injuries involve high-impact movements, particularly affecting the upper extremities, head, neck, and back during spins, balancing, landing, and sliding. Acute injuries included fractures and dislocations, while chronic conditions involved soft tissue injuries, stress fractures, and nerve compressions. Risk factors identified in case reports included the lack of training supervision and specific breaking maneuvers like flips, spins, and balancing acts. <b>Conclusion:</b> This is the first overview of case reports and letters to the editor that categorizes breaking injuries based on these types of papers.
