The purpose of this study was to investigate sartorius activity and angles of hip flexion, hip external rotation, and knee extension. These variables were evaluated during the two phases between passé and full extension of a développé devant. Data were collected for both parallel and turned-out positions about 90° of hip flexion on the preferred leg, in a sample of collegiate dancers.

Findings of the present study suggest that the sartorius experiences greater changes in muscle activity as a result of greater changes in ROM. Additionally, it can be deduced that the sartorius’s contribution to hip external rotation might be largely responsible for the muscle’s greater activity observed in turnout versus parallel. However, distinction of how much muscular activity is distributed towards each action of the sartorius at a given time cannot be concluded due to limitations in the equipment used. Further research is needed to understand the développé devant.
