Effects of leg fatigue due to exhaustive stair climbing on gait biomechanics while walking up a 10° incline – Implications for evacuation and work safety

This biomechanics study explored stride length (SL), stride duration (SDN), the peak of gait ground reaction forces (GRFspeak), required coefficient of friction (RCOFpeak), joints’ angle (anglepeak), angular velocity (angvelx peak), angular acceleration (angaccx peak), minimum angle (anglemin) of foot, and muscle electromyography (EMG) during the dominant leg stance phase (SP) following an exhaustive stair ascent for evacuation. Data were collected by a three-dimensional motion capture system synchronized with EMG and force plate when walking upwards on a 10° inclined walkway.
