The motor module is regarded as the strategy by which the central nervous system (CNS) simplifies various complex movements. It consists of two components:muscle synergy vectors (the relative weighting of muscles within each motor module) and synergy activation coefficient (the relative activation of the motor modules). This study investigated the structures of motor modules in athletes during gait. Eight elite hockey players and six non-athletes performed 10 trials of gait. Activity levels of sixteen lower limb and trunk muscles were recorded with electromyography and motor modules were extracted using non-negative matrix factorization. The least number of motor modules that can explain more than 90% (total variability accounted for; VAF total) of the original data were selected. Three statistical analyses were used to compare structures of motor modules in athletes and non-athletes: an independent t-test to record the number of motor modules, one-way analysis of variance to study muscle synergy vectors, and correlation analysis to determine synergy activation coefficients. Four motor modules were extracted from both athletes and non-athletes. Three motor modules were similar between the two groups (r>0.625) while one module was significantly different in the adductor muscles. Our study identified common motor modules between athletes and non-athletes during gait but also identified a specific motor module in athletes that demonstrated a high contribution of tensor fasciae latae.
