OBJECTIVE Reveal the characteristics of muscle force of 100 m hurdles female athlete in METHODS Surface electromyography (sEMG) signals are widely used to evaluate muscle force, In this work, a100 m hurdles female athlete has been made to analyze the complexity of sEMG signals in take‐off phase. 16 muscle were Selected in study, for example the deltoid toe, beam under the rectus, vastus lateral's muscle, erector spinae, gluteus maximums muscle, semitendinosus muscle, medial head of gastrocnemius muscle, tensor fascia lata and so on. RESULTS The sequence major muscle forcibly of the hurdle step skill in different stages as follows. In take‐off phase: the under rectus abdomen of the lead leg ←the glute maximus of the swinging leg ←the semitendinosus muscle of the lead leg← the deltoid toe of the lead leg. In flight phase: the under rectus abdomen of the lead leg ←the tensor fasciae latae muscle of the swinging leg ←the glute maximus of the swinging leg←the deltoid toe of the lead leg. In touch‐down phase: the glute maximus of the swinging leg ←the musculus semitendinosus of the swinging leg←the musculus semitendinosus of lead leg←the deltoid toe of the swinging leg. CONCLUSION It is found that the under rectus abdomen of the lead leg is the major muscle in take‐off phase, and the under rectus abdomen of the lead leg is the major muscle in flight phase, and the glute maximus of the swinging leg is the major muscle.
