Muscle Activations During Bulgarian Split Squat Exercise Variations
Condition: Sports Physical Therapy
Study type: Interventional

Summary: 
      It is essential to practice and train appropriate activation techniques to ensure optimum
      strength development. Knowing the effects of exercise variations that will minimize the
      tension forces acting on the knee by increasing the activation of the lumbo-pelvic-hip
      complex muscles, which are critical during sports activities, is extremely important in terms
      of preventing injuries. The aim of this study is to compare muscular activations during
      traditional and suspension-based Bulgarian split squat exercises and to examine the effect of
      trunk position on muscular activations.
    

Detailed description: 
      This study utilized a single-group repeated-measures design, where 4 conditions-Bugarian
      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)-were
      examined.Participants had to make two separate trips to the lab in order to be accepted into
      the study. All exercises were introduced to participants at the initial visit. Prior to
      beginning the exercises on the second visit, the participants' maximum voluntary isometric
      contraction (MVIC) values were calculated. The muscle activity of the gluteus medius (GMed),
      gluteus maximus (GMax), vastus lateralis (VL), rectus femoris (RF), vastus medialis (VM),
      semitendinosus (ST), biceps femoris (BF),and erector spina (ES) was monitored through the
      root mean square surface EMG signal amplitude. The order of the tasks was chosen for each
      person by straightforward randomization (by selecting from a deck of shuffled cards) so order
      to reduce the impact of the sequence of the exercises.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.
    

Intervention name(s): Bulgarian split squat exercise variations
Intervention type(s): Other
Intervention description(s): 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.
