Background: The correct activation of the trunk stabilizing muscles is essential in several situations, including prevention and treatment of low back pain. Proper activation of these muscles is a principle of the Pilates Method, but not all the effects of exercise variations are described in the literature. Objective: compare the electric activity of power house muscles (rectus abdominis, external oblique, internal oblique/transverse abdominal and multifidus) during the execution of the Leg Circles exercise with high spring and low spring in Cadillac apparatus. Methods: Ten Pilates instructors were selected, with 30 years (±5), 58 kg (±7), 163 cm (±7) who underwent maximum voluntary isometric contraction tests before the execution of the Leg Circles on the Cadillac, with high and low spring. The electrical activity of the rectus abdominis, internal oblique/transverso abdominal, external oblique and multifidus muscles was collected. Results: The internal oblique (p=0,002) and the multifidus (p=0,042) activations were greater on the high spring. However, the external oblique showed a higher activation on the lower spring (p = 0.001). The abdominal rectus did not change its activation = 0.375). Conclusion: The high spring can be considered as the most suitable position to ac-tivate the deep musculature of the trunk, since the greater activation of the multifidus and of the internal oblique/transverse abdominal, together with the lower activation of the external oblique and the low acti-vation in the rectus abdominus found in the high spring situation.
