From: A Proposed Framework to Describe Movement Variability within Sporting Tasks: A Scoping Review
Examples of the three types of movement variability and how they are assessed in a landing task. Strategies are determined by the joint with the greatest energy absorption, with two strategies categorised (knee-dominant landing and hip-dominant landing). Execution variability is represented by the continuous point-by-point standard deviation (SD) of time-normalised vertical ground reaction force traces for all landings within the same strategy. Outcome variability is represented by the SD of the outcome measure (peak force) across all strategies and executions. All forces are normalised to percentage time and expressed relative to body weight (N/BW = Newtons per body weight). (Unpublished data)
