Effects of self-paced incline treadmill walking on lower limb muscles activation level

The aim of this study was to investigate the effects of inclined walking on muscle activation level of biceps femoris (BF), soleus (SOL), and tibialis posterior (TP). Subjects included 28 able-bodied volunteers walked at the level and inclined self-paced instrumented treadmill. Uphill walking increased the muscle activation level of BF and SOL, while downhill walking increased muscle activation level of TP. Our findings suggest that inclined walking affects lower limb muscle activation level to maintain a comfortable and safe gait in able-bodied individuals.
