Introduction Aerobics is a combination of strength and beauty. The complexity of its movements is extreme, and it is easy to cause injuries from sports training in its athletes. Objective Analyze the effect of strength training on injury prevention in aerobic gymnastics. Methods The total duration of the experiment was 8 weeks, and the athletes in the experimental group were trained three times a week with the help of teachers in a dedicated strength training program. The exercise principle of the control group was to perform physical strength training based on running. The control group did not have the special protocol intervention. Their scores were collected and compared before and after the intervention. Statistical analysis was performed for scientific appreciation of the collected data. Results The scores on the deep squat, obstacle avoidance, front and back squat, scapular girdle joint flexibility, straight leg raising, stable trunk flexions, and rotational stability tests in the experimental group were all statistically differentiated. However, the control group’s scores had little difference, showing a slight decrease. Conclusion It is recommended to insert the presented program into the conventional aerobic gymnastics training, always with changes that adjust the reality of the athletes’ situation, protecting their physical health and improving their competitive level. Level of evidence II; Therapeutic studies - investigation of treatment results.
