Abstract in Portuguese
O objetivo desse estudo foi analisar a atividade eletromiográfica dos músculos tibial anterior (TA), fibular longo (FL) e gastrocnêmio lateral (GL) durante a aterrissagem após o bloqueio em jogadores de vôlei com instabilidade funcional (IF) de tornozelo. Foi analisada a atividade de 21 sujeitos com IF e 19 controles entre o desprendimento do solo e 200ms após o impacto. Os resultados mostraram padrões de ativação muscular que podem predispor o atleta à condição de instabilidade. Em indivíduos com IF, o TA e o FL apresentaram picos máximos de ativação mais tardios no ciclo de movimento, sendo que o TA apresentou maior valor de RMS após a aterrissagem (intervalo de 200ms após o impacto), e o FL, menor valor de RMS pré-terrissagem (intervalo de 100ms antes do impacto). A lém disso, no grupo controle o TA é ativado após o FL e o GL, enquanto no grupo com IF os três músculos ativam de forma praticamente simultânea, pois o GL apresenta um início de atividade muscular mais tardio.

Abstract in English
The purpose of this study was to compare electromyiographic activity (EMG) from peroneus longus (PL), tibialis anterior (TA) and gastrocnemius lateralis (GL) of volleyball athletes with and without functional ankle instability (FI) during landing after blocking maneuver. EMG from take-off to 200ms after impact was acquired for 21 athletes with FI and 19 healthy ones. Results showed that FI subjects have a muscle activity that predisposes them to ankle sprains: time of maximum peak occurrence was later for TA and PL, TA showed higher RMS values after landing (from impact to 200ms after), PL showed lower RMS values prior to landing (100ms before impact to foot contact). Control group showed differences in muscle onset latencies, TA onset occurs later than PL and GL, but in subjects with FI all muscles activate at the same time since GL shows higher onset latency.
