MUSCLE ACTIVATION SEQUENCE COMPROMISES VERTICAL JUMP PERFORMANCE Rafael Pereira1, Marco Machado1, Marcelo Miragaya dos Santos3,4, Lucas N. Pereira1, & Felipe Sampaio-Jorge2 1Laboratory of Physiology and Biokinetics – UNIG, Itaperuna – RJ 2Laboratory of Movement Analysis – ISECENSA, Campos dos Goytacazes – RJ 3ETE Ferreira Viana-Faetec/RJ, 4América Futebol Clube/RJ, BRASIL Abstract The vertical jump performance is influenced by biomechanical and neuromuscular features. An electromyographic assessment was made to evaluate the influence of motor control in jumping. Fifteen healthy subjects carried out three consecutive trials of vertical jumps, during which electromyography (EMG) was recorded of the muscles of vastus medialis (VM), rectus femuris (RF), biceps femuris (BF) and gastrocnemius lateralis (LG). The time of flight and the phases of the jump were identified by a pressure sensor. The results demonstrated a significant difference (p
