<b>Posture-induced modulation of lower-limb joint powers in perturbed running</b>

Data prepared for two-way repeated measures ANOVA to examine the main and interaction effects of <i>Step</i> (level-step and drop-step) and <i>Posture</i> (<i>TI¯</i>, <i>TI</i>_<em>0</em>, <i>TI</i>⁺, and <i>TI</i>⁺⁺) on the total limb and joints negative and positive powers.Abbreviations:<br><b>Abs</b>: absorption or negative work; <b>Gen</b>: generation or positive work.<br><b>Level-step:</b>1: <i>TI</i>_<em>0</em><i>, </i>self-selected trunk inclination; 2: <i>TI</i>⁺<i>, </i>low forward trunk inclination; 3: <i>TI¯</i><i>,</i> backward trunk inclination; 4: <i>TI</i>⁺⁺<i>,</i> high forward trunk inclination.<b>Drop-step:</b>5: <i>TI</i>_<em>0</em><i>, </i>self-selected trunk inclination; 6: <i>TI</i>⁺<i>, </i>low forward trunk inclination; 7: <i>TI¯</i><i>,</i> backward trunk inclination; 8: <i>TI</i>⁺⁺<i>,</i> high forward trunk inclination.---------------------------------------------------------------------------------------------------------------------------------------------------------avrg_Hip_Pow_Nrm + avrg_Knee_Pow_Nrm + avrg_Ankle_Pow_Nrmarray structure: 100 x 8 x 12 x 2 =&gt;1008122<br>1:4 (Level-step)5:8 (drop-step)<br><br>Normalized joint power<i>Posture order:</i>1:4=&gt; <i>TI</i>_<em>0</em>, <i>TI</i>⁺, <i>TI¯ </i>and <i>TI</i>⁺⁺5:8=&gt; <i>TI</i>_<em>0</em>, <i>TI</i>⁺, <i>TI¯ </i>and <i>TI</i>⁺⁺Participants1: Left limb2: right limb** for this study we only analyzed the right limb data (2^nd contact). The experimental setup involved 2 force plates where participants instructed to step onto the 1^st force plate with the left foot. We lowered the 2^nd force plate by 10cm to simulate the drop-step.
