- Primary Outcome Measures
Name Time Method <p>Average muscle activity (in mV) of uniarticular leg extensor muscles (i.e.<br /><br>gluteus maximus, vastus lateralis, vastus medialis, soleus) during positive and<br /><br>negative joint work separately.</p><br>
- Secondary Outcome Measures
Name Time Method <p>Average muscle activity (in mV) of biarticular leg muscles (i.e. biceps<br /><br>femoris, semitendinosus, rectus femoris, gastrocnemius medialis) and<br /><br>uniarticular leg flexor muscles (i.e. tibialis anterior) during positive and<br /><br>negative joint work separately.<br /><br><br /><br>Time duration of muscle activity (in ms) of leg flexor and extensor muscles<br /><br>during positive and negative joint work separately.<br /><br><br /><br>Joint kinetics during gait:<br /><br>- Negative joint work (hip, knee, ankle) (in J/kg/m)<br /><br>- Positive joint work (hip, knee, ankle) (in J/kg/m)<br /><br><br /><br>Subject anthropometrics:<br /><br>- Body height<br /><br>- Body weight</p><br>
