This study utilized isokinetic strength testing technology to assess hip flexion-extension and internal-external rotation muscle strength in 24 ballet students and 24 regular university students, in order to explore the impact of ballet training on hip joint muscle strength. The results showed that the flexion-extension muscle group in the ballet group had significantly higher values in five metrics (peak torque, relative peak torque, relative work, relative peak power, and peak torque ratio) compared to the control group (P<0.05). The male ballet participants' flexion-extension peak torque (180°/s: 265.26±39.55 N·m) was comparable to that of fencing athletes. In the internal-external rotation tests, the ballet group exhibited significantly higher external rotation muscle metrics, with an increase of 32.5-74.4%, while the internal rotation metrics showed no significant differences when compared to the control group. Interestingly, the female ballet group showed a 19.4% reduction in internal rotation work at 180°/s (P<0.05). The study suggests that long-term ballet training significantly enhances hip flexion-extension strength and external rotation strength, forming a specialized characteristic of external rotation dominance and flexion-extension synergy. However, the development of the internal rotation muscle group lags behind.
