Various types of walking are characterized through the predominant fractions of eccentric and concentric muscle contractions. Walking in part can be more efficient by the function of muscle works and the superior efficient of eccentric versus concentric contractions. Muscle activations during eccentric and concentric contraction during different mode of walking determined in many different ways and different methods. Nonetheless, the experimental measures are not always repeatable and/or identical as no all quantifications of muscle activations can be entirely accurate. On this basis, accordingly, our finding has provided a critical approach for synchronous sEMG and 2-D high – speed camera in quantification of the eccentric and concentric muscle activations of rectus femories muscle (RF) and bicep femories (BF) synergic muscles on unchallenging level and downhill walking. In fact, tracking the muscular electromyography (EMG) with kinematic mode did not yield a reliable outcome. To meet this challenge experiment different approaches such as musculoskeletal modelling might be useful technique in these quantifications and in understanding of distinct walking characteristics.
