Muscle Activations During Bulgarian Split Squat Exercise Variations

The participants performed 4 different sessions of Bulgarian split squat exercises-Bulgarian split squat with trunk flexion (BSS flexion), Bulgarian Split squat with trunk neutral (BSS neutral), suspension based Bulgarian split squat with trunk flexion (SBSS flexion), suspension based Bulgarian split squat with trunk neutral (SBSS neutral)-with EMG recordings being taken from the dominant extremity throughout each session. For each exercise, participants were instructed to perform three successful repetitions. Between each repetition, there was a 30-second break, and there was at least 10 minutes in between each of the 4 exercises. The movement was standardized by a metronome. The modified Borg scale was used to ensure that fatigue did not occur before each exercise since it was believed that fatigue could affect exercise performance. When scores reported using the modified Borg scale were 1 or lower, exercise recording was started.
