Posture-induced modulation of lower-limb joint powers in perturbed running

Data prepared for two-way repeated measures ANOVA to examine the main and interaction effects of Step (level-step and drop-step) and Posture (TI¯, TI0, TI+, and TI++) on the total limb and joints negative and positive powers.Abbreviations:Abs: absorption or negative work; Gen: generation or positive work.Level-step:1: TI0, self-selected trunk inclination; 2: TI+, low forward trunk inclination; 3: TI¯, backward trunk inclination; 4: TI++, high forward trunk inclination.Drop-step:5: TI0, self-selected trunk inclination; 6: TI+, low forward trunk inclination; 7: TI¯, backward trunk inclination; 8: TI++, high forward trunk inclination.---------------------------------------------------------------------------------------------------------------------------------------------------------avrg_Hip_Pow_Nrm + avrg_Knee_Pow_Nrm + avrg_Ankle_Pow_Nrmarray structure: 100 x 8 x 12 x 2 =>10081221:4 (Level-step)5:8 (drop-step)Normalized joint powerPosture order:1:4=> TI0, TI+, TI¯ and TI++5:8=> TI0, TI+, TI¯ and TI++Participants1: Left limb2: right limb** for this study we only analyzed the right limb data (2nd contact). The experimental setup involved 2 force plates where participants instructed to step onto the 1st force plate with the left foot. We lowered the 2nd force plate by 10cm to simulate the drop-step.
