BM = Body Mass DL = Dominant Leg Gmax = Gluteus Maximus Gmed = Gluteus Medius MVIC = Maximum voluntary isometric contraction Clam Shell 1 = Side‐lying with hips flexed to 45 °. Externally rotate top leg Clam Shell 2 = same as Clam 1 but internally rotate the top leg (knees together) Clam Shell 3 = Top thigh raised to parallel to table with hip in neutral rotation and 45 ° of flexion. Top leg then internally rotated. Knee height remains the same throughout the entire movement. Clam Shell 4 = Same as 3 except the top leg is in extension Clam shell PNHIP0 = pelvis neutral, hip in 0 ° of flexion Clam shell PNHIP30 = pelvis neutral, hip in 30 ° of flexion Clam shell PNHIP60 = pelvis neutral, hip in 60 ° of flexion Clam shell PRHIP0 = pelvis reclined, hip in 0 ° of flexion Clam shell PRHIP30 = pelvis reclined, hip in 30 ° of flexion Clam shell PRHIP60 = pelvis reclined, hip in 60 ° of flexion Borg = Borg Rating of Perceived Exertion CR10
