Loading conditions: Moments (positive for external flexion moment) as a function of joint angle averaged over all repetitions and all subject plots are plotted for all BE exercise types (solid: BEh, dashed: BEs; blue: 2L, green: 1L; *: starting point) (a): Normalised knee moment in the sagittal plane [Nm/kg] as a function of the corresponding knee flexion angle [°]. b: Normalised hip moment in the sagittal plane [Nm/kg] as a function of the corresponding hip flexion angle [°]. c: Normalised back moment at the level L4/L5 in the sagittal plane [Nm/kg] as a function of the corresponding lumbar curvature [1/m]. d: Normalised thoracic curvature in the sagittal plane [1/m] for a cycle [%]
