Effects of Neuromuscular Training on the Reaction Time and Electromechanical Delay of the Peroneus Longus Muscle

Runway set-up.

Electromyographic signals for electromechanical delay measurement. The first vertical line marks the point at which the muscle became active (the first spike is stimulus artifact). The second vertical line marks the beginning of the eversion moment. The space/time between the 2 lines represents the electromechanical delay. Abbreviation: PL, peroneus longus.

Electromyographic signal for reaction time measurement. The vertical line marks the fall of the trap door and the beginning point used to calculate reaction time. Peroneus longus muscle onset was the second point used to calculate reaction time (1). Peak inversion ROM (2) was used to calculate time to total inversion ROM. Abbreviation: R, right.
