ABSTRACT

The purpose of this study was to compare three clam exercises (clam, modified clam 1, and modified clam 2) used in the Pilates physical fitness system, to examine the activity of the gluteus medius and tensor fascia latae and to determine which of the three exercises maximizes the activity of the gluteus medius while minimizing the activity of the tensor fascia latae. Twenty healthy volunteers participated in this study. Surface electromyography (sEMG) was used to measure the electrical activities of the gluteus medius (GMed) and tensor fascia latae (TFL). This study showed significant differences between GMed and TFL muscle activities according to each of the three clam exercises (p < 0.05). The gluteus medius showed the highest activity during modified clam 2 and the lowest in clam (p < 0.05). Tensor fascia latae showed the lowest activity during clam and the highest in modified clam 2 (p < 0.05). The gluteus medius to tensor fascia latae ratio was the highest in modified clam 1 and the lowest in modified clam 2 (p < 0.05). Therefore, these findings inform clinicians and Pilates instructors that the appropriate exercise to maximize the activity of the gluteus medius while minimizing the activity of the tensor facia latae is modified clam 1.
