Muscle activity as a percent of maximal volitional isometric contraction (% MVIC) as measured by electromyography during each phase of a side‐foot kick, based on data from Brophy et al (2007).

% MVIC	Preparation	Backswing	Leg Cocking	Leg Acceleration	Follow Through
Iliacus	28	65	128	106	95

^*Greater than 100% represents muscle activity greater than that measured during maximal volitional isometric contraction
