CO-CONTRACTION OF TIBIALIS ANTERIOR AND SOLEUS MUSCLES DURING EXERCISES WITH DIFFERENT CONDITIONS OF INSTABILITY
Keywords: Biomechanics, Electromyography, Muscle Co-Contraction, Joint Stability
AbstractThis study aimed to compare the level of co-contraction of shank muscles during five different types of instability. Six healthy male adults performed ten balance exercises, five double leg and five single leg, while myoelectric activity of tibialis anterior and soleus was collected. Significant differences were identified in the level of muscular co-contraction between exercises performed on the BOSU and exercises performed without instability devices. It is conclude that there is a trend toward progression of balance exercises to increase the joint ankle stability, allowing physical therapists and physical educators to develop more efficient training programs aiming at improving levels of MCC and prevent injuries.
