It remains unknown if hip joint forces during squat tasks are altered in people with femoroacetabular impingement syndrome (FAI). This study investigates hip joint forces among people with FAI and healthy controls during double and single leg squat tasks.The AnyBody Modeling System was used to calculate hip joint angles, forces, and moments for eight individuals with FAI and eight matched healthy participants. Statistical nonparametric mapping (SnPM) analysis showed that patients with FAI demonstrated lower proximodistal hip joint forces during single leg squat than healthy controls and their non-affected leg, suggesting they may adopt a strategy to avoid pain during this high-demand task. In contrast, during double leg squats – which is a less demanding task – no differences in terms of hip joint forces were observed between patients and healthy individuals. These results can enhance the understanding of FAI’s impact on hip functionality during high-demand tasks.
