CrossFit® is a physical training method that combines resistance, aerobics, mobility, flexibility, and power exercises. Although it promotes significant gains in strength and performance, the practice is also associated with a high incidence of injuries, particularly in the shoulder, knee, and ankle regions. Therefore, this study aimed to analyze the correlation between the angular kinematics of the spine, hip, and ankle joints—considering flexion and extension angles in the sagittal plane—during the overhead squat movement and the level of shoulder pain in CrossFit® athletes. Ten volunteers of both sexes, aged over 18 years, who had been practicing CrossFit® for at least six months and reported shoulder pain during the overhead squat, participated in this study. Data collection was carried out in CrossFit® gyms in Bauru, São Paulo, using specific software and a camera positioned in the sagittal plane, three meters from the participant. The movements were recorded at a frequency of 100 Hz during five repetitions of the exercise. The maximum flexion and extension angles of the spine, hip, and ankle joints were analyzed. Pain intensity was assessed using the Visual Analog Scale (VAS), and the correlation between kinematic data and VAS scores was evaluated using Pearson’s correlation test, with a significance level of p < 0.05. The results indicated a correlation between shoulder pain intensity and the angular kinematics of the analyzed joints, suggesting that changes in movement patterns may be related to shoulder pain in CrossFit® practitioners.
