Is the knee joint more vulnerable to injury in unplanned cutting tasks? An EMG vector field analysis of high-level female athletes Open
The knee might be more vulnerable to injury in unplanned tasks due to lower muscular pre-activity. Muscle activity does not vary with pKAM, suggesting passive structures must absorb higher loads with increasing pKAM. Differences in vastus …
