  Background and Objectives: Abdominal muscles' strength has a large impact on the trunk, sustains static, and reduces the pressure on the lumbar spine. Therefore, the purpose of the present study was to compare the motor unit electrical activity of the abdominal muscles during different positions of sit-up.

  Materials and Methods: This experimental study was conducted on valunter fifteen participates without any history of neural diseases male . Surface electromyography were measured from rectus abdomen’s, oblique externus during sit-up exercise. Student t-test was used for statistical analysis.

  Results : The results indicated that the rectus femora’s muscle in sit-ups flexed and supported leg exercise whereas their activity in sit-up. Also the oblique externus abdominal muscle was more active in sit-up extended and supported legs exercise than their activity in sit-up extended and supported legs.

  Conclusion : The functional results of this study help to coach, notice to this fact that strengthen any muscle with motion that more involved it.

  Key words: Sit-up, Electromyography, Rectus abdominals, Oblique externus and Rectus femoris muscles


  Funding: This research was funded by Islamic Azad University Branch.

  Conflict of interest: None declared.

  Ethical approval: The Ethics Committee of Islamic Azad University Branch approved the study.
