Muscular Activations During Eccentric Quadriceps Exercises

The activation of the vastus medialis, vastus lateralis, and rectus femoris muscles will be measured using surface electromyography (sEMG) during four distinct quadriceps eccentric exercises: Reverse Nordic, Pistol squat, Suspension-based Bulgarian split squat, and Bulgarian split squat. Participants will be instructed to perform three successful repetitions for each exercise. A 30-second break will be provided between each repetition, and there will be a minimum of 10 minutes of rest between each of the four exercises. Due to the belief that fatigue could impact exercise performance, the modified Borg scale will be used to ensure that fatigue does not occur before each exercise. Exercise recording will commence when scores reported using the modified Borg scale are 1 or lower.
