, angular position was calculated as the position of the segment distal to the joint relative to the proximal segment (e.g., hip joint angle was computed as the position of the thigh segment relative to the pelvis). The trunk angle was calculated as the position of the trunk segment relative to the global

athletes appropriately interpreted the injury definition, they were also asked to provide the diagnosis (if any) that they were given by a physician, trainer, or physical therapist. For each injury, athletes listed the affected body part (low back, pelvis, or right/left hip, thigh, knee, shin, ankle, or

Following the standing calibration trial, subjects performed double-leg drop landings from a 31-cm high box

Also, 5% to 6% of adult sports injuries occur at the hip and pelvis. 9 – 11 It is important for allied health and fitness professionals to be able to recognize common hip musculoskeletal conditions and how they can affect movements, such as the squat. Of interest are the effects of common hip

self-paced treadmill surrounded by a 180° projection screen allows an individual to be immersed in an activity or scene. A self-paced treadmill speed algorithm ( Sloot, van der Krogt, & Harlaar, 2014 ) incorporating anterior–posterior pelvis position relative to the center of the treadmill to control

filtered using a fourth order Butterworth filter with a 6 Hz cut-off, and a 7 segment (pelvis, thighs, shanks and feet) model was constructed. The pelvis segment’s center of mass (COM) position was established 6 and then COM velocity was calculated as the first derivative of COM position. Walking

clusters were used to track the thigh, shank, and foot segments during the movement trials. The pelvis was tracked by the markers placed on the posterior superior iliac spines and on the iliac crests. With the markers in place, a standing calibration trial was captured. The 3-dimensional positions of the
