Abstract

This study aimed to determine differences in muscle activation between habitual rearfoot strike pattern (RFS) and non-rearfoot strike pattern (NRFS) runners. Ten habitual RFS and ten habitual NRFS runners were recruited in this study. The electromyography signals were collected from the tibialis anterior, soleus, medial and lateral gastrocnemius muscles at 9 km/h running. The root mean square of each muscle and the co-activation of ankle flexors and extensors (CO_Ankle) were calculated. Independent t-tests or nonparametric tests were used to examine the differences between two groups. The results showed that during the pre-activation and swing phases, the CO_Ankle of RFS runners were greater than those of NRFS runners. This suggested that RFS runners with higher CO_Ankle at pre-activation might be a strategy in response to great impact force during the early of stance.
