To assess if biofeedback provides a useful training aid to improve
performance, real-time biofeedback on biomechanical variables
that were considered to be fundamental elements of shooting were
provided to top-level shooters. Most biomechanical-stability variables
demonstrated a decrease in range from 3.0 s to 0.1 s prior to
the shot, demonstrating a strategy whereby shooters gradually
improve stability prior to triggering the shot. The one exception to
this pattern was that the front foot AeP COP range spiked to
maximum instability at between 1.0 and 0.3 s before the shot. It is
possible this ‘spike’ is owing to subtle movements to increase the force on the trigger.
