Description
Investigations of human movement variability have been used as a
means of exploring neuromotor functioning, where performance variability is
thought to provide the system with flexibility and a mechanism for adaptation to
movement repetition [1,2,4,6]. Operationally, variability has been considered to
fall within optimal limits (Figure 1), while excessively high or low variability has
been implicated in injury susceptibility [1,2,4,6]. Landing has been explored
due to a high incidence of injury in athletic performance, as well as the ability
to easily control task demands through increases in landing height [3,4].
The purpose of this investigation was to evaluate changes in lower
extremity kinetic variability in the frontal plane, exploring gender comparisons
during landing. Peak frontal plane joint moments were used to access
variability across landing heights at the hip, knee, and ankle joints. Landing
height was increased as a proportion of maximum vertical jump height (MVJH),
which characterized lower extremity functioning across a range of task
demands.
