Vertical Takeoff Acceleration Asymmetry
A measure of the difference in Vertical Takeoff Acceleration (VTA) between feet. High VTA asymmetry (>15%) occurs when one side leaves the ground at a faster rate than the other. This can mean either poorer push ability on one side, or a protective strategy to offload certain muscle groups on one side.
Asymmetry measures are best used in conjunction with a baseline for each individual, as every person has inherent asymmetries.
