Graphs describing no difference between visits for the flexion exercise, SLR, and “Jane Fonda” exercise. A: knee angles in the sagittal plane (flexion/extension) and B: hip angle in the transverse plane (rotation) during the knee flexion exercise; C: knee angles in the sagittal plane (flexion/extension) during SLR and D: hip angle in the sagittal plane (flexion/extension) during the “Jane Fonda” exercise). Solid lines represent the average of 5 repetitions for each exercise at the first visit while dotted lines represent the same for the second visit; the shaded gray area around each line represents standard deviation of the 5 repetitions; X-axis: time normalized in percentage
