The purpose of this study was to investigate the recruitment of the paraspinal muscles longissimus and iliocostalis during dynamic contractions of superman exercises on stable and unstable surfaces, and during unloaded bodyweight squats. Surface electromyography (EMG) was measured from these two muscles bilaterally while participants performed the exercises. Participants (n = 17, age 24 ± 3.1 years, body mass 78.5 ± 8.2 kg, height 1.81 ± 7.4 m) performed two sets of 10 repetitions for each exercise in a random order. Correlation analysis demonstrated a strong positive relation between both sides of the participants (longissimus pairs: r = 0.945; and iliocostalis pairs: r = 0.855), demonstrating a symmetric muscle recruitment in all exercises. However, there were no significant differences between the exercises for both muscles in a multiple comparison analysis (longissimus pairs: p = 0.496; and iliocostalis pairs: p = 0.296). The bodyweight squat produces similar muscle activity of the longissimus and iliocostalis compared with superman exercises on stable and unstable surfaces. Considering the dynamic nature of the bodyweight squat, and its implications on functional daily living activities and sports conditions, it seems a more reasonable choice for targeting paraspinal muscles if compared to superman exercises or unstable superman exercises.
