Introduction: Chinese martial art has a wide and deep history, and its routine passes are a particular artistic presentation. In exhibitions, choreography with jumping is highly appreciated. Empirically, it is believed that additional strengthening of the lower limbs may promote better results in the performances, but there are no reports in the scientific literature about such a statement. Objective: Verify the consequences of lower limb strength training on jumping ability in martial arts athletes. Methods: 30 first and second tier athletes from the professional women’s team of the Wushu Sports Management Center and Sports Bureau were selected as volunteers for the experimental research. The experiment lasted for three months. The characteristics of the development and change of strength of each muscle group in the knee joint of the athletes’ lower limb during the experimental training were detailed, and the commonly used means of lower limb strength training were found. Results: In strength training, the best means found were skipping steps and rapidly changing direction. The correlation coefficient between jumping and strength was 0.75. Conclusion: After the experiment, the maximum torque and the average power of the lower limb knee muscle groups of the three experimental groups increased in different ranges, which shows that the strength quality of the knee joint of the athletes increased during the suggested training.
