Professional dancers are exposed to significant physical strain and a high risk of injury during their daily training, according to research released on Mar. 19 by Goethe University Frankfurt. The study measured the musculoskeletal stress experienced by 28 professional ballet dancers using sensor-equipped suits during their regular training sessions.
The findings highlight the demanding nature of professional dance, which often remains hidden from audiences who see only the grace and apparent effortlessness on stage. The research underscores the need for improved injury prevention measures in the profession.
The study involved both female and male dancers from Oldenburg State Theater and Theater Kiel, who wore suits that recorded acceleration and body positioning at a rate of 240 measurements per second. The data showed that more than 60 percent of training time was spent in a moderate-risk range for physical strain, with an additional 30 percent in a high-risk range. "Our participants spent more than 60 percent of their training time in a moderate-risk, and a further 30 percent in a high-risk range," said Dr. Wanke, one of the researchers involved in the project.
Female dancers were found to spend more time in higher-risk ranges compared to their male counterparts, possibly due to differences in body structure that make certain movements more strenuous for them. The study also noted that classical dance training has changed little over centuries and follows a three-phase structure, with dynamic exercises increasing as sessions progress. "Studies show that concentration tends to decline in Phase 3, leading to more frequent errors and inaccuracies," Wanke said.
The researchers suggest scheduling particularly demanding exercises earlier in training sessions and adapting routines based on gender-specific needs. They also recommend organizational changes at performance venues—such as installing specialized dance floors—to help reduce injury risks caused by high-impact landings during jumps.
Wanke concluded that further research is needed to determine which structural measures are most effective at reducing forces experienced by dancers: "This would be an important focus for future research."
