Abstract: | This investigation compared the amplitude and the timing of the muscle activity of the lower limb, as well as the three-dimensional
kinematics of the hip, knee and ankle joints, of male and female elite soccer players performing an unanticipated cutting
manoeuvre. These data were recorded for 15 female and 15 male participants for five successful cutting manoeuvres. For this
manoeuvre to be performed in an unanticipated manner, the participants were instructed to execute one of three tasks, which
were signalled to them with a target board composed of three different coloured lights. Female participants performed the
cutting manoeuvre with greater lateral gastrocnemius activity in comparison with the male participants. It was also observed
that they contracted their vastus lateralis to a greater extent than their vastus medialis, whereas the men adopted the opposite
strategy. These neuromuscular control strategies adopted by the female athletes may elucidate the reasons for which women
struck the ground with a more abducted knee during the cutting task. Given that this knee position places greater strain on
the anterior cruciate ligament, a restoration of the medial/lateral activation balance of the lower limb muscles may reduce
one’s risk of injury. |
