Several studies have demonstrated that dance training can enhance muscle strength. This study aims to compare the muscle strength of ankle joints between college students with and without ballet dance training, analyzing the differences between the two groups and explaining the influence of dance on muscle strength. A total of 48 healthy college students volunteered to participate, with the experimental group consisting of 24 ballet students (12 males, aged 21.5±0.9 years; 12 females, aged 20.9±1.8 years) and the control group consisting of 24 non-dance students (12 males, aged 20.7±0.9 years; 12 females, aged 20.6±0.8 years). The German ISOMED2000 Isokinetic test device was used to measure ankle joint strength, with angular velocities set at 60° and 180° and the testing mode set to concentric-concentric. The testing included ankle joint flexion and extension movements, and the measured indicators included peak torque (PT), relative peak torque (PT/BW), relative work (TW/BW), relative peak power (PP/BW), and peak torque ratio of flexion and extension(H/Q). By comparing these five indicators of ankle joint isokinetic motion between ballet students and non-dance students, as well as comparing the results with athlete data, the following findings were observed: 1) Ballet students exhibited higher peak torque, relative peak torque, and relative peak power of ankle joint flexor muscles compared to non-dance students, indicating that ballet training significantly improves the maximum strength of ankle joint flexor muscles. 2) The comparison of relative work indicates that ballet training significantly enhances the work capacity of ankle joint flexor muscles. 3) Through the comparison of relative work, relative peak torque, and peak torque ratio of flexion and extension, it was observed that sports such as short-track speed skating and fencing, similar to ballet, can significantly improve ankle joint flexor muscle strength. However, short-track speed skaters and fencers showed higher relative strength in ankle joint extensor muscles compared to non-dance students, whereas ballet students exhibited relatively lower relative strength in ankle joint extensor muscles compared to non-dance students.
