Twenty experienced skydivers performed two terminal velocity skydives each. Surface electromyography quantified muscle activity bilaterally from the anterior neck, the upper and lower posterior neck, and the upper shoulders; and two triaxial accelerometers sampled deceleration. Muscle activity was normalized as the percentage of reference maximum voluntary electrical activity (%\n                    <jats:styled-content style=\"fixed-case\">MVE<\/jats:styled-content>\n                    ); and temporal muscle activity onset was related to\n                    <jats:styled-content style=\"fixed-case\">POS<\/jats:styled-content>\n                    onset.
