Introduction: As competitive martial arts develop rapidly, technical difficulty and training intensity continues increasing, neck injuries in athletes have also increased proportionally, attracting the attention of researchers. Localized strength training is used for rehabilitation, but there is no research related to prevention in athletes. Objective: Explore the neck strength training effect on neck injury prevention in martial arts athletes. Methods: 68 (34 male) volunteers attended the experiment randomly divided into control and experimental groups. Traditional training activities were practiced in the control group, while a strength training protocol was added in the experimental group. Indices of change in pain, motor quality, and neck disability index were compared. Results: After the test, the number of neck injuries in the control group was 23, compared to five in the experimental group; there is a significant difference. There was a significant reduction of injuries in the experimental group (P=0.05); one year later, the VAS score of the experimental group remained significantly lower than the same pre-experiment or control group. The neck dysfunction score of the experimental group was still significantly lower than the pre-experimental and control group; there was no statistically significant difference between the control group and the experimental group before the experiment. Conclusion: The adequate periodic neck strength training formulation has a significant preventive effect on neck injuries in martial arts athletes.
